Thanks, Kim. Now let me review the quarter in the context of the business segments and provide detailed color as appropriate. First, Aerospace. Aerospace did particularly well in the quarter. It had revenue of $3.03 billion and operating earnings of 432 million with a 14.3% operating margin. Revenue is $942 million more than last year's first quarter, a 45.2% increase. To give you a little color here, the increase was driven by a 50% increase in aircraft deliveries, including 13 new G700s and higher services revenue at both Gulfstream and Jet Aviation. The 36 deliveries in the quarter are about as planned. Recall, however, that there were no G700 deliveries in the first quarter of 2024. So this quarter really shows the robust revenue increase driven by the introduction of the G700. In addition, we saw improved margins on our G700 deliveries. In short, we expect revenue growth throughout the year, but at a slowing rate of growth because G700 deliveries began in the second quarter of last year. As I indicated last quarter, the supply chain continues to improve and is performing better to both schedule and quality. We are finding fewer faults and those we are finding are becoming easier to fix. In short, I am increasingly confident that we can meet this year's delivery plan. We are also pleased that the G800 was certified by both the FAA and EASA on April 16th. This is expected to be a smooth entry into service and we have some reason to believe that we can exceed our planned deliveries of G800. I would be remiss if I failed to mention that Jet Aviation made a significant contribution to the quarter's results. Its revenue was up 8% and earnings up 22% over the year ago quarter on 160 basis point improvement in operating margin. This business has become a real jewel. In summary, the aerospace team has had a good quarter. G800 FAA and EASA certification is behind us and we are improving our G700 delivery cadence and operating margin. Turning to market demand, we had a 0.8 book-to-bill in the quarter even as aircraft deliveries increased by 50%. Orders are consistent with our internal plan at about the same number of units as the first quarter in 2023 and 2024. We expect that the certification of the G800, it's better than plant performance characteristics and the early deliveries to customers will stimulate demand. We continue to see improved interest across all models in the U.S. albeit with cautious concern by customers about the macroeconomic environment and the impact of tariffs on their businesses. Middle East activity remains strong, so let's move on to the defense businesses. Combat had revenue of $2.18 billion, up 3.5% over the year ago quarter. Earnings of $291 million are up 3.2%. Margins at 13.4% are consistent with the year ago quarter. It's interesting to observe that this year's revenue growth is on top of our first quarter 2024 growth of almost 20%, so nice compound growth. The increased revenue performance occurred at Ordnance and Tactical Systems in European land systems, land systems held steady. We also experienced good order performance. Orders in the quarter drove backlog to 16.9 billion, up 3 billion from this time a year ago. Demand for combat system products continues to be robust with particular strength in Europe. Orders for wheeled and tracked vehicles are up, reflecting the heightened threat environment. In addition to several new combat vehicle starts, we are working closely with the U.S. Army to accelerate Abrams modernization. In the U.S. we are rapidly increasing munitions capacity and production with the opening of our projectile facility in Texas and our load and assembly and PAC facility in Arkansas. All-in-all, Combat had a solid quarter and is off to a good start for the year. Turning to Marine Systems, once again, our shipbuilding units are demonstrating impressive revenue growth. Let me repeat the recent history that I gave you at this time last year with respect to growth in this decade. The first quarter 2020 was up 9.1% against Q1, 2019. Q1, 2021 was up 10.6% over Q1, 2020. Q1, 2022 is up 6.8% over Q1, 2021. Q1, 2023 was up 12.9% over Q1, 2022. Q1 2024 was up 11.3% over Q1, 2023. And finally, this quarter is up 7.7% over Q1.24. This has been a really nice rate of growth for the shipyards and the repair yards. This growth has come at significant cost for facilities and significant increase in hiring. The good news is we've been able to hire and train the people we require to support our growth. This particular quarter's growth was driven by Columbia Class and Virginia Class construction, as well as an increase in DDG-51 construction. Operating earnings are $250 million in the quarter, up 7.8% from the year ago quarter. Operating margin is identical to last year's quarter. We have struggled to achieve operating leverage to go with our rapid revenue growth, but operating earnings have grown on a consistent basis as well. We continue to be impacted by delays and quality problems in the supply chain. Material and parts are late and sometimes exhibit quality escapes, and new shipbuilders continue to come down learning curves. We have more work to do, but we have made progress. In addition, one of the unions, the draftsmen's, a largely white collar union that converts engineering specs to drawing has voted to authorize the strike. We are working closely with the Navy and the new administration to continue to address the problems in the supply chain and look for opportunities to improve throughput and performance at the shipyard. The growth profile continues to look strong and demand is not abated. Our job is to continue to improve ourselves and to help the industrial base get stronger with the help of the government. The Technologies Group had a strong start to the year with revenue of $3.43 billion. This was an increase of 6.8% over the first quarter of 2024. Both businesses contributed to the growth in the quarter with GDIT up 9% and Mission Systems up almost 2%. Operating earnings of $328 million were up 11.2% over the year ago quarter on a 40 basis point improvement in operating margins from 9.2% to 9.6%. The operating margin improvement is encouraging given the top line shift toward IT services, which carry a lower margin than the defense electronics side of the portfolio. This reflects strong performance admission systems as the transition from legacy programs to new franchises continues. The group's order activity was also encouraging with a book-to-bill of 1.1 times for the quarter and trailing 12 months even against the strong revenue growth. As a result, the group's backlog is up almost 7% from a year ago and their total estimated contract value is up more than 10% over the same period. Their focus on advanced technology enabling autonomous platforms, smart munitions, subsea warfare and strategic deterrence as well as advanced AI, cloud, cyber 5G and quantum solutions is driving demand for the group. Their pipeline of qualified opportunities remains strong at 120 billion and their win and capture rates in the 80% range reflect the compelling value they're providing their customers. While this year is off to a strong start, a significant amount of uncertainty hangs over the market, particularly on the IT services side of the business as the administration establishes its own spending priorities. That said, our team has a great understanding of the government's emerging technology needs and is committed to innovating to solve the toughest technical challenges across the government at the best return for their customers. As you know, we never update guidance at this time of year. Apart from what I've already said about aerospace, I will continue with that practice. There is, however, no hiding from this quarter's performance and its implication for the year. Let me speak to tariffs for a moment. We cannot yet discern to what extent the defense businesses will be impacted over time. The more potentially impactful problem is in aerospace, where we are a significant net provider of export revenue to the U.S. We do not know the scope and breadth of the tariffs issue at the moment and will not for a while. Accordingly, anything I might say on that subject would be sheer speculation. So I do not intend to answer questions on the subject of tariffs because anything I say on that subject, given our lack firm of knowledge, will almost certainly be wrong. Rest assured that we are working the related issues diligently. This concludes my remarks about a good quarter and let me turn the call back to Nicole to take questions.
