Thank you, Todd. We're pleased to have you aboard as our Vice President of Investor Relations. I also want to thank Steve Movius for his many years of service in that role. Good afternoon, everyone. Welcome to our third quarter 2019 earnings call. I want to thank the entire Northrop Grumman team for another solid quarter. We delivered strong business capture and backlog growth, higher sales at all four sectors, strong earnings, and healthy cash flow. Year-to-date results supported a substantial increase in our EPS guidance, as well as an increase to the lower end of the free cash flow guidance. We are on track to achieve the other major elements of guidance. Before discussing the quarter in more detail, I want to touch on the realignment we announced in September.
Beginning in January, we will have four operating sectors that more closely align with our customers' priority investment areas. Our new sectors are Aeronautics Systems, Defense Systems, Mission Systems, and Space Systems. These changes will enable our teams to quickly identify and deliver solutions for rapidly evolving national security challenges. The realignment is also aimed at driving continued strong execution, sustained profitable growth, and operational efficiency. Under the new structure, Aerospace Systems becomes Aeronautics Systems and continues under the leadership of Janis Pamiljans. In addition to long-duration franchise manned and unmanned programs, the sector will also include the aerostructures work currently being performed at Innovation Systems. A new sector, Defense Systems, brings together Technology Services, the defense businesses of Innovation Systems, and select capabilities for Mission Systems.
In addition to being our global sustainment and modernization business, Defense Systems includes tactical missiles, munitions, and our integrated air and missile defense programs. Defense Systems will focus on products and services that address evolving threats and quick turn requirements for a wide variety of national security, military, civil, and international customers. Chris Jones, the President of Technology Services, has announced his intention to retire. I want to thank Chris for his many contributions to Northrop Grumman, particularly for leading the effort to position Technology Services for the future. We wish him the best. Mary Petryszyn, who currently heads land and avionics C4ISR within Mission Systems, will lead the new sector. Mission Systems remains largely intact, but with a sharpened focus on growing its leadership position in open, cybersecure, software-defined systems for defense and intelligence applications. Mark Caylor will continue to lead Mission Systems.
The fourth and final sector, Space Systems, brings together our significant space and launch capabilities from across the company into one organization. Space Systems will be a robust platform to accelerate the development of innovative and affordable offerings for our national security, military, civil, commercial, and international customers. We expect Space Systems will be the fastest-growing sector in our new structure. Blake Larson, currently the President of Innovation Systems, will lead Space Systems. This realignment is the next logical step to maximize the powerful revenue synergy opportunity we envision from our combination with Orbital ATK. It also further enables strong execution and our organization's agility. Turning to financial highlights for the quarter. Sales rose 5% to approximately $8.5 billion and included sales growth at all four sectors. Our year-to-date segment operating margin rate of 11.5% is tracking to our guidance of approximately 11.5% for the year, reflecting solid operational results.
Cash from operations increased $327 million to $1.1 billion in the third quarter, and free cash flow increased to $882 million. Year to date, operations have generated $1.8 billion of cash. After capital expenditures of approximately $800 million, year to date free cash flow increased to approximately $1 billion. New awards remain robust and demonstrate our strong competitive position in critical national security domains. In the third quarter, we booked more than $10 billion in new awards or 1.2 times sales. Book-to-bill was above one at Innovation Systems, Mission Systems, and Technology Services. At Aerospace Systems, year-to-date book-to-bill is 1.6 times sales and backlog is up 28%. During the third quarter, Japan exercised an option for nine additional E-2D Advanced Hawkeyes for approximately $1.4 billion. This is in addition to the $3.3 billion multi-year award we booked last quarter.
I would also note that France has indicated they're interested in purchasing three E-2Ds. At Innovation Systems, we booked the initial $300 million of a $1.1 billion Missile Defense Agency competitive award to supply new targets and countermeasures used to test the Ballistic Missile Defense System. Our offering provides a new solution to the complex threat scenarios our customers face. I'd also note that IS has been awarded approximately $1.3 billion for hypersonic and counter-hypersonic activities as both a prime and subcontractor. At Mission Systems, we were awarded a 13-year IDIQ contract to produce and sustain next-generation navigation systems for the U.S. Air Force and international customers. This sole source award has a potential value of $1.4 billion. Mission Systems also booked a six-year, $375 million order to provide surveillance radars for the Navy's Triton aircraft and a $200 million IDIQ award for our Layered Systems and related support.
At Technology Services, in addition to winning two large recompetes, TS won a competitive restricted award valued in the hundreds of millions of dollars. We're particularly pleased with this award as it demonstrates the sector's ability to win new restricted work and expand our national security services portfolio. A good indicator of our company's portfolio alignment to the National Defense Strategy is our growing share of restricted work. Year-to-date, restricted awards total $8.5 billion. At the company level, restricted work across multiple domains continues to grow as a % of total revenue. As of September 30th, total restricted backlog has grown 22% since year-end, and new awards of approximately $36 billion are 1.4 times year-to-date sales. Looking ahead, we have large opportunities across our portfolio in all four sectors and program execution remains solid. Turning to Aerospace Systems. F-35 production continues to ramp up.
Year-to-date, AS has delivered 100 center fuselage units, and we are on pace to deliver a total of 134 units in 2019, 13 more than last year. As we celebrate the 30th anniversary of our B-2 Spirit, the world's first stealth bomber, we continue to perform well on the B-21 Raider, our nation's next-generation stealth bomber. Last month, the then acting Secretary of the Air Force, Matt Donovan, noted that the development program is on schedule and production will occur in Palmdale, California. At Mission Systems, our IBCS system successfully intercepted a cruise missile at an extended range with Sentinel and Patriot systems. The flight test demonstrated the value of IBCS to detect, track, and engage low-flying threats at a distance well beyond the range limitation of the current Patriot system.
In August, Innovation Systems submitted our proposal for the National Security Space Launch down select, which is currently planned for the third quarter of 2020. Our OmegA vehicle is on track to meet the customer's requirement for a first launch in 2021 and operational launches of national security payloads in 2022. On GBSD, we have assembled an exceptional nationwide industry team that is ready to meet the Air Force's technical and schedule requirements. We are successfully executing on the TMRR phase of the program. We look forward to submitting our proposal for the next phase of the competition. The Air Force has been clear that our nation urgently needs to modernize the ICBM system. It is critical that this acquisition remains on schedule. Turning to the U.S. defense budget. We're now working under a continuing resolution that expires on November 21st.
More often than not, we begin each fiscal year under a CR, and we don't expect this to cause a significant disruption to our fourth quarter activities or our outlook for next year, as long as there is not a prolonged CR. Our customers need predictable funding that is not constrained by continuing resolution limits. This enables investment in the critical technologies we need to stay ahead of rapidly advancing global threats. We believe our nation's leaders will provide the necessary resources to modernize key capabilities, and therefore, we are hopeful that the government will act quickly to finalize appropriations. In closing, based on a solid quarter, strong year-to-date performance, and our outlook for the remainder of the year, we are again increasing 2019 earnings per share guidance.
We now expect mark-to-market EPS will range between $20.10 and $20.35. We are maintaining our sales guidance of approximately $34 billion. We are updating our free cash flow guidance by raising the bottom end of the range by $100 million. We now expect free cash flow of $2.7 to $3 billion for the year. Regarding the 2020 outlook, we will provide detailed guidance in January. We expect mid-single-digit sales growth in 2020, which now includes the impact of the Lake City contract winding down in the latter part of the year. We also expect segment margin rates consistent with 2019 and strong and growing free cash flow. Now I'll turn the call over to Ken for a more detailed discussion of our financial results and guidance. Ken?
Thanks, Kathy, and good afternoon, everyone. I also want to thank the team for another solid quarter. We had excellent awards, strong book-to-bill, and higher sales at all four sectors. Year-to-date awards support our outlook for continued top-line growth. As Kathy said, we are tracking to our segment margin rate guidance. Turning to the sectors. Aerospace Systems sales rose 5%. Higher manned aircraft reflects volume increases on the E-2D and F-35 programs. Space sales also increased, reflecting growing activity on next-gen OPIR programs. Autonomous system sales were also higher due to volume increases in multiple areas, including Global Hawk. AS third quarter operating income declined to $324 million, and operating margin rate was 9.4%. This was driven by lower net favorable EAC adjustments. AS had fewer favorable adjustments this quarter, primarily due to timing. We also had negative performance adjustments on two activities.
The B-2 Defensive Management System Modernization program is experiencing schedule delays. Although the upgrade has taken longer than planned, installation of DMS has been completed on the first test aircraft, and aircraft checkout is underway. AS has now completed most milestones on the program and are well along toward completion. We also experienced production delays for certain commercial space components. We have introduced new leadership and processes in this business in order to successfully complete these contracts. In both cases, we believe our current EACs have captured the cost to complete the required work. Excluding these two adjustments, AS third quarter margin rate would have been in the mid 10% range. We continue to expect AS sales for the year in the high $13 billion range. We are maintaining operating margin rate guidance of mid to high 10% with a bias toward the lower end of the range.
At Innovation Systems, third quarter sales rose 12% in its first full quarter comparison. In space, we had higher volume on national security satellite systems. Defense systems had higher volume on precision munitions, armaments, and tactical missiles, including the AARGM-ER program. Flight systems had increased volume on military and commercial aerospace structures. IS operating income increased 2%, reflecting higher sales. Operating margin rate for the quarter was solid at 10.4%. The prior year period benefited from favorable indirect performance and the recovery of an insurance claim. Year to date, operating margin rate is 11.1%. For the year, we continue to expect IS sales of approximately $6 billion with a high 10% operating margin rate. No change to prior guidance. Turning to Mission Systems. Third quarter sales grew 4%, and operating income was comparable to last year. Advanced capabilities had higher volume on marine programs.
Cyber and ISR had higher volume on space and restricted programs. Sensors and processing had increased activity on airborne radar and electronic warfare programs, including F-35 and radars. Based on year-to-date results, we continue to expect MS revenue to grow to the low to mid $12 billion range, and we are raising margin rate guidance to the low 13% range. At Technology Services, sales rose 3%, and operating income rose 23%, with an operating margin rate of 12.7%. As we discussed last quarter, program headwinds are moderating, and we are now seeing the underlying sales growth in both TS businesses. Operating income benefited from a focus on cost reduction, as well as a favorable adjustment on a sustainment program. We continue to expect TS sales in the low $4 billion range. No change to prior guidance.
Based on strong year-to-date performance, we are raising guidance for TS operating margin rate. We now expect a high 10% range versus prior guidance of low 10%. As we roll all that up, we continue to expect 2019 sales of approximately $34 billion with a total segment operating margin rate of approximately 11.5%. Below segment OM, we continue to expect unallocated corporate expense of $225 million. Unallocated corporate expense is typically higher in the fourth quarter, and our guidance contemplates an estimate for state deferred taxes and year-end accruals. We are increasing our guidance for total operating margin rate to approximately 11%, largely due to updated CAS pension estimates as we completed our annual demographic study. The presentation materials we posted this morning include updated estimates for CAS, net FAS/CAS pension adjustment, and required funding for 2019 through 2021.
Our 2019 estimates do not include the mark-to-market adjustment we will be recording in the fourth quarter. 2020 and 2021 estimates are based on year-to-date trends and assume a discount rate of 3.31%, 12% plan asset return in 2019, and 8% plan asset returns thereafter. Through September 30, our actual returns were about 14%. I'd also note that our CAS prepayment credit approximates $2 billion. The demographic study increased 2019 CAS and net FAS CAS adjustment by $60 million. For 2020 and 2021, our updated assumptions increased net FAS CAS adjustments by $140 million and $80 million respectively, and over the three-year period, our required funding is about $100 million lower. Moving to taxes. Our effective tax rate for the quarter was 11.6%. Based on year-to-date results and our updated fourth quarter analysis, we now expect a tax rate in the low 16% range for the year.
Wrapping all that up considering year-to-date results, we are increasing our mark-to-market adjusted earnings per share guidance to a range of $20.10 to $20.35. This continues to be based on approximately 170 million weighted average shares outstanding. Free cash flow increased $352 million in the quarter. Year-to-date, we've generated more than $1 billion in free cash flow. Based on year-to-date results and our fourth quarter outlook, we are raising the bottom end of the free cash flow range by $100 million. We now expect $2.7 billion-$3 billion for the year. We continue to expect capital expenditures of approximately $1.2 billion, as well as share repurchases of approximately $750 million. As planned, we retired $500 million of debt in the third quarter. Beyond this year, we expect growing cash flows driven by higher sales and earnings, some improvements in working capital, and modest required pension funding.
Regarding capital expenditures, we continue to invest in growth opportunities as robust backlog growth continues. We are still targeting CapEx at about 2.5% of sales in 2021. In summary, we had a solid third quarter, and we expect strong results for the remainder of the year. I think we're ready for Q&A. Todd?
Erica, we're ready for questions.
Ladies and gentlemen, if you wish to ask a question, please press star followed by one on your touch tone telephone. Again, press star one to ask a question. If your question has been answered or you wish to exit the questions queue, press the pound key to exit the queue. Press star zero at any time for operator assistance. Your first question comes from Peter Arment with Baird.
Good afternoon, Kathy, Ken, Todd. Welcome.
Thanks.
Kathy, thanks for all the details on the realignment. Could you maybe give us just your thoughts on sometimes when you do a realignment, you do shine a bright light on something that doesn't fit. Is this going to result in any portfolio shaping? Just any updated thoughts on that. Thanks.
Thanks for the question, and you're absolutely right. As we did this realignment, we looked in depth at what we had in the portfolio to ensure that we were getting things aligned in a way that would create the most value for the company going forward, and I'm really pleased with the structure we're putting in place. It seizes the opportunity that we knew we had in space to bring the portfolio together in the new Space Systems. I'm also excited about the creation of the Defense Systems, as it brings together some of our munitions and integrated air and missile defense capabilities in a tighter way, along with our sustainment strategies, which deal with customers' very quick term requirements. This has really been about the forward look in our company and seizing those opportunities that exist.
As we did shine a light on the whole of the portfolio, there wasn't anything that didn't fit within the structure that we created. Of course, I continue to look at that on a regular basis. As we execute the strategies that we've defined in this newer realignment, we'll continue to assess just that question.
Your next question comes from Ron Epstein with Bank of America Merrill Lynch.
Hi, good afternoon, everyone. This is Kristine Liwag dialing in for Ron today.
Hey, Kristine.
In AS, I just wanted to follow up on the B-2 Defensive Management System Modernization effort. Are the operating issues you're facing there related to the rebaselining of the program? Also, should we expect lower margins in this program to continue to your B-2 contracts going forward, or is this issue kind of a one-time thing?
Kristine, I'll start and then hand it over to Ken to talk about the financial implications of what we saw in B-2 this quarter. We're managing thousands of contracts across the company and delivering very strong performance, and sometimes contracts are rebaselined, as we did report earlier in the year on the B-2 program. What we saw this quarter was an adjustment there that Ken outlined in his comments.
Related to the performance on that program. We feel very good about where we are in completing major milestones on our way to finalizing and executing the B-2 program. It is complex to update a system of that type, but we now have our arms around those challenges. I'll turn it over to Ken to talk a little more about the financial implications.
Thanks, Kathy and Kristine. Appreciate the question. Let me just say that, as I mentioned in my comments, we do believe that our EAC reflects the cost that we think will be required to complete the program. As we look at our portfolio, and I'll just go back to Kathy's comments, a portfolio of many different programs and contracts across not just the aerospace sector, but across the company. We don't expect this program, as it will book essentially a lower margin from now until completion, to have any material impact on our overall segment margin rate at either AS or in total for the company. Again, given the very diverse portfolio that we manage on a day-to-day basis.
Your next question comes from Seth Seifman with JP Morgan.
Hey. Good morning. Thanks. Ken, maybe if you could talk about, you mentioned repaying some of the debt. When you look out beyond this year, there's some debt coming due each of the next couple of years. Can you talk about the approach that you plan to take there?
Sure, Seth. I would say, as we look forward, we do have debt coming due. We also have a growing EBITDA as we look at growing the business, growing the top line, and maintaining strong margins. That growing EBITDA gives us some naturally de-leveraging there. As we look at that, I would say we've got some optionality on what to do, and depending on the value-creating opportunities that we see in front of us will very much shape what we do in terms of that debt repayment strategy. We'll continue to evaluate what are the most value-creating uses of our capital, and that'll really shape it.
Your next question comes from Sheila Kahyaoglu with Jefferies.
Thank you. Good afternoon, Kathy and Ken.
Hey, Sheila.
Kathy, you made some preliminary comments on 2020. Can you talk about your comments regarding margin mix and having it consistent or margins being consistent? Can you talk about mix within the portfolio, how you see it transitioning from mature to development programs? If you could give some color.
We'll be giving detailed guidance in January in our new structural alignment. My comment did apply to the company as a whole, seeing our segment operating margin rate stay consistent with 2019 guidance. As we look at what's happening within our segment operating margin rates, we are taking on additional development work, and there is some downward pressure on margin rates as a result. We're also having very good cost management, which is offsetting our rates and allowing us to keep both competitive rates to win new business, but also healthy segment operating margin rates. We expect that trend to continue into 2020. It's like a duck on water. While we're remaining consistent, there's a lot happening beneath to keep those margin rates consistent, even as we take on additional development work.
Okay. Thank you.
Your next question comes from David Strauss with Barclays.
Thanks. Good afternoon, everyone. On the mid-single-digit sales growth guidance, Ken, you had been hinting potentially at something higher than that on the last call. I know you talked about Lake City. Was Lake City kind of the only change versus what you said prior, and how does that impact things in 2020, and I guess into 2021 as well? Thanks.
Of course. As we look at our sales growth for 2020, really Lake City is the biggest impact that we see versus the previous outlook that we had provided. We look at Lake City as probably having about a 1% impact on what we had expected for 2020 sales. Certainly, as we look forward, we see, again, after Lake City coming out mid-single sales growth, solid margins, and then again, that growing cash. We're looking forward to performing on the existing portfolio, driving that growth, and turning that into margin cash.
Your next question comes from Rajeev Lalwani with Morgan Stanley.
Hi, good afternoon. Ken, question for you. Just coming back to the couple of comments you made on cash. I appreciate the color on easing CapEx and improving working capital. Can you maybe take it a step further and give us an idea of what conversion looks like over the next few years and maybe in 2021, in particular, given your comments there on CapEx levels?
Sure, Rajeev. Let me first comment. From a conversion perspective, I would just say you really need to be careful as you think about conversion for a number of reasons. First of all, the pension impact, as well as the amortization of PI and things like that. Let me really focus on how we're looking at cash and as we look forward to 2020 and beyond. We'll provide detailed guidance in January and walk you through all that. I'll just say that we've been clear that this business is going to be a strong generator of cash as we look forward. Let me just walk through some of the drivers there. As I said, we continue to expect solid sales growth for several years, and that's really driven by our portfolio alignment to customer needs.
I would say it's demonstrated by the strong backlog that we've been generating, and quite frankly, we continue to expect to generate in Q4 and 2020. As I mentioned, we continue to expect to generate strong margins and convert those margins into cash.
Yeah, that's what I was just about to take it and ask you, do you want to say it or can I just turn it?
Erica, can you mute the other line, please? Given our confidence on our expected 2019 cash performance, we did increase the bottom end of the range, as Kathy mentioned, to $2.7 billion. We continue to be confident on our 2020 free cash flow growth. As we've been investing in the business to drive growth, a lot of that investment at AS, where we've grown the business 30% in three years, and at IS, that'll grow double digits in 2019. We continue to expect about $1.2 billion of CapEx this year or about 3.5% of sales. Looking at 2020, we expect CapEx to be in the range of 3%-3.5% of sales as we trend down to the 2.5% range in 2021.
I'd just say these investments continue to support our growing backlog and a robust set of near-term opportunities across multiple domains, including restricted space. Just moving on from CapEx, again, pensions are well-funded, some of the best-funded plans in the industry, and that offers us structural advantage in our new business captures. Working capital, as I mentioned, should moderate a bit starting in 2020. A bit more opportunity probably in the out years. Some of that being timing of cash receipt milestones and some of that continued focus on solid working capital management.
Your next question is from Doug Harned with Bernstein.
Thank you. Good afternoon.
Hey, Doug.
Hi. I wanted to understand a little bit better the growth trajectory on the AS side. If you look at the elements of this and you have F-35, clearly there's some restricted space growth. On autonomous systems, in the release you refer to Global Hawk, but when we look at autonomous systems, it looks heavily biased toward HALE systems, and those appear to be somewhat episodic in nature around Global Hawk, Nanoedge, Triton. Can you talk about how we should think about this as more of a long-term trajectory with autonomous platforms?
Yeah, Doug. As I think about the opportunity for unmanned systems, we've clearly seen some adoption for unmanned in applications like intelligence, surveillance, and reconnaissance. As we look into the future, we believe unmanned systems will be utilized for more missions, and we also see the opportunity for more international sales of unmanned systems as export regulations are considered and perhaps addressed to allow more of this capability to get into the hands of our allied nations. When we think about UAS over a long-term trajectory, we see a continued evolution of these platforms into additional missions. We see them continuing to evolve in terms of their technical capabilities, and these are the areas that we are investing in as a company. Today, there's everything from remotely piloted to truly autonomous systems.
As you know, we tend to operate on the high end of that spectrum, and we believe more missions will continue to evolve to that higher-end capability as well.
Your next question comes from Myles Walton with UBS.
Thanks. Good afternoon. Hey, Kathy. I know that in the 10-Q, you allude to the FTC disclosure, specifically as it relates to the competition for GBSD. I'm just curious, in your conversations with the customer, how they may or may not view this as an impediment to kind of bids being received, which I guess mid-December is the timeline for that.
Thanks, Myles. We did indeed receive an inquiry from the FTC, and I want to note that we've been working with the FTC and the Department of Defense to ensure our compliance with the FTC's decision and order that governs our ability to enter into the transaction of acquiring Orbital ATK, and we're going to continue to do so. This is just a more formal inquiry that we are responding to as part of this latest request, and that's why we disclosed it in the 10-Q. With regard to the GBSD competition, we haven't seen any changes regarding the RFP process since the final RFP was released this summer. As you know, we have established a nationwide team, and it's ready to go in meeting the U.S. Air Force's technical and schedule requirements for the competition. We're looking forward to supporting and submitting our proposal in December.
We've had no indications that there'll be any change to the acquisition strategy, at this point. Both the department and the Air Force have made statements as recently as this week about their support for the program.
Your next question comes from Carter Copeland with Melius Research.
Hey, good afternoon, team. Kathy, I just wanted to ask about more broadly program performance. This is, I think, only the second quarter I can recall in a decade where there were more than one negative performance call-out, and I think the last one was a little more than a year ago. I just want to make sure there's not some sort of trend here that, especially with the realignment, you guys will have some stuff moving around. I wonder as we go through that, if you can just talk about your confidence level that you have that other stuff may not emerge as you go through that process, because it's got a lot of complexity, and you guys are managing a lot right now. Just broadly, if you could speak to program performance, I'd appreciate it.
Yeah. Thanks, Carter. As I look at our program performance, it continues to be very strong. I'm particularly proud with some of the large development efforts that we've undertaken, as well as our ramp on major production programs, that we are delivering on those very well. You've seen some public statements by our customers about how pleased they are with our performance on some of those. I won't rehash them here. Every year, we do have a small number of programs that require negative EAC adjustments based on performance out of the thousands of contracts that we're managing. Sometimes the timing of those adjustments causes a particular segment's operating margin rate to fall below our expectations in that quarter. You're referring to that this quarter with AS and a little over a year ago, with Mission Systems.
As you've seen over time, our performance management has remained strong, and we're yielding good margins as a result of these circumstances being few and far between and fairly isolated. That was the case that you saw in AS this quarter. I'll also note we had positive EAC adjustments that delivered above expected segment operating margins, and that happened in TS this quarter and is driving the increase in segment operating margin guidance at both MS and TS for the year. Performance overall is still very strong in our company, and as a result, we're continuing to hold our guidance for the year on operating margin performance.
Carter, if I could just add, I would say that in terms of the items that we called out this quarter, we were really trying to indicate what was the trend between last year's third quarter and this year's third quarter and help you understand the movement there as opposed to trying to identify the two items as having a longer impact on our performance. Really, it was a comment with respect to just the trend between Q3 2018 and Q3 2019.
Your next question comes from Robert Spingarn with Credit Suisse.
Hi, good afternoon. Hey, guys. I wanted to turn to TS, especially since we really won't be able to see it in the future, but it seems like under the hood, it's accelerating here with high single-digit growth to the U.S. government, double-digit growth internationally. Since the headwinds are dissipating here in Q4, could this business, in its old form, for example, see mid to high single-digit sales growth next year if we thought about it in its present form? Because I think that's going to be a little bit obscured, so I'm curious.
Rob, certainly this year we have worked to reposition TS to be more competitive. That's been some good cost management. It's been rebuilding a stronger pipeline, and I'm really proud of what the team has done there. You see in the third quarter a return to growth year-over-year and strong operating margins. I believe that can persist, and as we've said, we do expect this to be a growing segment of our business in 2020. I would not go as far to say high single digits. I would see it more in the low to mid-single digits. It is on a bit of a ramp, and we still have some VITA burning off through the remainder of this year. That would be my macro outlook, and I'll hand it to Ken for any other comments he wants to make.
I guess what I would say is, just to kind of frame up TS for the quarter and just to make sure we're all on the same page, we did see 3% growth at TS quarter-over-quarter. I think you might be referring to in the schedules in the footnotes, there were some higher sales to the U.S. government as opposed to some inter-segment sales. We've been working at TS to, essentially for TS to be the prime on certain international programs and particularly international HALE and some others where they were previously a sub to AS. I think you're seeing somewhat there is they are priming some of those programs that are some FMS, some through the U.S. government as well. There was some B-2 work where they were previously through AS, where now they're the prime.
As we look at it at a top level, 3% growth this quarter, we look forward to the continued growth of the TS sector in 2020, as it's a part of the Defense Systems. Broadly, we wouldn't necessarily see it in that high single-digit range that you were referring to. I think some of that is just movement in the different parts between intersegment and the prime work.
Your next question comes from Noah Poponak with Goldman Sachs.
Hi. Good afternoon, everyone.
Hey, Noah.
Good afternoon.
Ken, just going back to the segment margins for 2020. I think you've talked about the possibility of expanding margins modestly over time here, because you've mixed down a bunch over the past few years and maybe have hit a floor in that mixing down. In 2020, at AS, you'll be now comping against the issue in this quarter, hopefully not repeating it. Lake City out, I think helps the margin compare. Mission Systems is your largest earnings contributor and highest margin segment, and I think may grow the fastest next year. Actually, would love to hear your thoughts on that, since that one's maybe not accelerating as quickly as we thought. It seems like there are some margin uppers next year.
Am I not appreciating how much development or classified work is still coming in, or should we be thinking about flat as a floor with some upside potential?
As we look at 2020 margins, I would say, first of all, as we think about 2019, we are essentially for the full year, still projecting where we expect it to be for 2019 from a segment margin basis. Each of the sectors is consistent to where it's been, with the exception of TS, where we're looking at that increasing. You had some questions about AS, I would say, again, their forecast for '19 is consistent with where it is today. I don't necessarily think of that differently from a Lake City perspective. Certainly, we don't see that as having a significant impact overall on the portfolio. Just kind of thinking through it, we'll provide guidance in January when we get to that point.
We certainly will work in 2020 to continue to perform on our portfolio and see the ability to drive up those margin rates, as we work through the year and we've tried to do in the past. We do continue to have some early-phase development work. In particular, IS has some early-phase development work in the restricted space area or in the national security space, as we call it. That will be one of the drivers to what you will see, I think, to your question about the fastest grower, what I think you'll ultimately see as the Space sector as the fastest grower in 2020. Again, we'll provide more detail and guidance when we get to the January call.
Your next question comes from Jon Raviv with Citi.
Thank you. Just following up on margin question in 2020, but a bit bigger picture. Ken, you started talking about the IS classified being some of the pressure there. Can you just identify some other areas of the business that are seeing more of that development pressure? On a related note, is there something different about the development that you're doing today versus what you were doing maybe a few years ago that might be putting a little more pressure on early on rates? Perhaps anything to do with contract structures requiring more risk up front or anything like that? Thank you.
As we look at it, I don't see anything different, honestly, Jon, with respect to what we're doing today. Simply when we start in the early phase of a long development program, we're identifying the risks and therefore we're tending to book a lower rate as we try to burn down those risks over time. No change in how that's worked over the years. I think the biggest change being that we're seeing more opportunities for early development growth, and those are opportunities that we're more than willing to take on. Those will lead to those next generation production programs that will provide that additional opportunity for margin expansion down the road. I don't see any change. As I think about some of the restricted programs, they may not be multi-year awards, but many of them are multi-year in periods of performance.
We're just managing risk over that long-term period of performance and, again, trying to create those opportunities as we look forward.
Your next question comes from Cai von Rumohr with Cowen and Company.
Thank you very much. Maybe going back to Myles's question, the FTC investigation. Do you expect it to have any impact on when the GBSD decision might be made, and roughly when might that be? Have you had any pressure or kind of suggestion from the customer that maybe you might consider the national team proposal that Boeing has made?
Cai, we do not currently expect any change to the Air Force acquisition strategy as a result of this inquiry. They do plan to award next August, there is some time. Our proposal is due in December, obviously we will continue to monitor that. Right now, we do not see any impact. In terms of the question about any pressure, we are not receiving any pressure to engage in a national team, because I would point out that we do have a, what we're calling nationwide team that includes many large and small companies across the country who are bringing strong capability that will support our GBSD bid.
Your next question comes from Richard Safran with Buckingham.
Thanks. Kathy, Ken, Todd, good afternoon. How are you?
Good. How are you, Rich?
Well, thanks.
An F-35 question with just a few parts to it as usual, partly based on your opening remarks. The House and Senate fiscal 2021 markup has an increase in the F-35 quantities by 12 or 18 aircraft, depending on which version you believe, impacting, I think, lot 14. To the best you can, as always, could you tell us what's being assumed in your 2020 guide for F-35 quantities? Kathy, you mentioned no disruption to your guide from the CR, but I wanted to know, and maybe it's pressing you a little bit here, is it possible that you could alter your guide depending on what happens in November when the CR expires and we potentially have a budget with possibly higher F-35 quantities? Do you think you've likely captured all likely scenarios? Finally, you've had enviable margins on the program.
Just wanted to know if that continues with the block buy. Thanks.
Right. I'll start with some of your more macro questions and then turn it to Ken on the quantities specifically. As I noted in my comments, we do not see an impact on our guide for a short-term CR. If we were to sustain a longer-term CR, that would impact and cause us to revisit our guidance, and I would include F-35 quantity in that statement. We have contemplated the possible quantities on F-35 changing through the appropriations process and feel that that's adequately reflected, will be, in our guide for 2020, because of course, at this point, we've just given 2020 outlook. The other thing that I'll note is on F-35, we continue to focus on performing and driving down the cost curve and being a good partner to Lockheed Martin.
We also have opportunities on the program that are causing some growth for us over the next several years. One, of course, is increased sustainment work on the program, which I've spoken to before, and we're also seeing growth from the Block 4 modernization program. We're working new development on our sensors, specifically radar, comms, navigation, and identification sensors, and this will yield production opportunity in the long term. We think lots 14 and beyond. We have some production growth to support additional sparing with quantities increasing between lots 12 and 14. Those aren't significant drivers. They're not nearly as significant as the production quantity itself. Those are some additional opportunities that we have in both the near and the longer term on the program. I'll turn it to Ken to add anything he'd like.
I think you've nailed it there, Kathy. I would say we certainly wouldn't want to go into the quantities that we've assumed for our 2020 outlook at this point, Rich. We are continuing to perform on the program, proud of the performance that we've seen at both, really, at all of the sectors who are supporting the program, supporting our customers. We have continued to increase quantities, and we'll see some continued ramp. Kathy kind of talked about what that longer term profile looks like. I think that really captures it.
Erica, we have time for one more question.
Your final question comes from George Shapiro with Shapiro Research.
Yes. You made a comment that Lake City would be about 1% sales impact next year. That says to me that you may have Lake City for half of the year, because I would have thought the total impact would have been about 2% of sales. My second question is, how long does the current B-2 contract for which you took what looked like a pretty sizable hit in the quarter last? Thanks.
Sure. Thanks, George. On Lake City, you are correct. We do have a transition from ourselves to the new provider of that service, and so we will be performing on that program for at least the first half of the year for 2020. We will see some volume on that. The 1% I was referring to was actually the reduction that we see to the previous
outlook we had for sales. About a 1% reduction to our previous outlook relative to Lake City. From a B-2 perspective, George, I wouldn't want to comment extensively on the period of performance other than to say that, as I mentioned in my remarks, we're well along on the program. We're making good progress. We're passing milestones. I would just point out to your question about the substantial amount of the adjustment. I would just say that, in regards to the adjustments at Aerospace Systems this quarter, neither one of them was in excess of $20 million. Again, we largely highlighted those as having impact on the trend from our Q3 margin rate of 2018 to our Q3 margin rate of 2019. Just a little color there for you.
Okay. I'd like to turn the call over to Kathy for final remarks.
Thank you, Todd. One correction from my commentary that I want to make sure I convey is the total backlog, not total restricted backlog growth year to date is 22%. Again, I want to thank our team for another strong quarter of financial and operating performance. We're executing well, building on our backlog for profitable growth and strategically aligned to our customers' highest priorities. All of this provides us an exceptional platform for sustained value creation. We're focused on delivering a solid finish to 2019 and a strong start to 2020 with our new organization alignment. I look forward to updating you again in January and providing detailed 2020 guidance in that call. Thank you for joining our call today.
Ladies and gentlemen, that concludes today's conference call. Thank you for your participation.
