Thanks, Todd. Good morning, everyone. Thank you for joining us today for our first quarter earnings conference call. A lot has happened since our last call in January. We're looking forward to providing you an update on the quarter, and our expectations for the year. We are operating in a rapidly evolving world, and we are managing through a dynamic US defense budget environment. With a first-of-its-kind full-year continuing resolution. Within this environment, we continue to see strong demand signals from our global customers, resulting in another record backlog in the first quarter of $92.8 billion, and that's inclusive of strong international bookings. As we indicated in mid-February, we've experienced delays in certain awards, which resulted in a slower sales ramp in the first quarter than we previously anticipated. We expect this to improve throughout the year. Margin rates, setting aside the B-21 adjustment, were in line with expectations. We have updated our 2025 financial guidance and we are reaffirming our outlook for sales and free cash flow. With a growing backlog and progress on award timing, we have confidence in achieving our outlook and remain focused on delivering transformative capabilities for our customers. I'd like to take a minute to discuss the B-21 profit adjustment made in the quarter. As you saw in the earnings release, we recognized an additional $477 million pretax loss. This is largely relating to higher manufacturing costs primarily resulting from a process change we made to enable higher production as well as increases in the projected material costs, some of which are related to macroeconomic impacts on material prices. While I'm disappointed with this financial impact, we continue to make solid progress on the program. Demonstrating performance objectives through tests, and we are progressing through the first two lots of production. With significant learning behind us, we are ready to deliver the Air Force this highly capable strategic deterrent. During the quarter, we continued to make significant progress on other key programs as well. On Sentinel, the US Air Force and Northrop Grumman Corporation completed a successful static fire test of the stage one solid rocket motor for the missile in March. This critical milestone for the weapon system further validates the motor's design and paves the way for the production and deployment of a safe, secure, and reliable strategic deterrent. We are also continuing to work with the customer to identify cost and schedule efficiencies. As they evaluate requirements to balance capability, affordability, and schedule for the program. In January, the US Army awarded us a nearly $500 million contract for IBCS. Under this award, Northrop Grumman Corporation will expand software development and include additional AI and model-based systems engineering capabilities. To allow more rapid integration, for the Army, and our international partners. Earlier this month, we announced the opening of a state-of-the-art production and integration facility in Alabama to support accelerated modernization plans for air and missile defense systems, including IBCS. With this investment, it doubles the size of the previous facility footprint, leverages Northrop Grumman Corporation's digital ecosystem, and gives us the ability to scale production, and field new capabilities at speed. Also, we received nearly $300 million in awards in the first quarter from the U.S. Navy to produce two additional Triton aircraft and associated support services. We are also making good progress on delivering Tritons to Australia. The first of four was delivered last year, and the second and third aircraft have completed testing with the US Navy prior to delivery to the Royal Australian Air Force this year. Triton is playing a critical role surveilling high-priority areas of interest in multiple regions. It was just announced last week that Triton will soon be deployed from Southern Japan to commence surveillance and information-gathering operations. I'd like to take the next few minutes to provide our view of the market outlook for both the industry in general and Northrop Grumman Corporation more specifically. For our industry, demand ultimately stems from the global threat environment. Over the past decade, this environment has grown increasingly complex with the reemergence of peer adversaries. Making the pace of innovation and production crucial for deterrence. As a result, our global customers are increasing their investments in national security. In the US, we continue to see signs that defense spending will increase. Driven by a few ongoing developments. The first is the finalization of a continuing resolution for the 2025 defense budget. This CR comes with several provisions that set it apart from previous ones. The most notable of which are an increase in the top line over FY24 and increased flexibility with spending accounts. Meanwhile, there is a push for additional funding through the reconciliation process. Which could add up to $150 billion to the defense budget to be allocated over multiple years. Both the House and the Senate have passed initial legislation that lays the groundwork for this additional funding. We believe much of this will be used to support investments to maintain our nation's edge against evolving global threats. Lastly, the administration continues to prepare their fiscal year 2026 budget request. And we are encouraged by recent commentary that suggests a continued strong commitment to national security funding at levels higher than prior projections. The administration has highlighted key priority areas such as the triad, missile defense, and weapon systems, all of which are aligned to core capabilities of Northrop Grumman Corporation. Additionally, the significant increase in defense investment outside the US is leading to a growing pipeline of requests for our products across Europe, Asia Pacific, and the Middle East. As countries seek to protect their sovereign territories, and deter aggression. In Q1, our international sales represented approximately 14% of total sales. We have broadened our customer base, and increased the number of products that we can sell internationally, and established new partnerships globally to enhance our addressable market. As a result, we continue to see our opportunities to increase our international sales over the coming years. And we are making steady progress in this area. With a first-quarter international book-to-bill of 1.45 times. And international sales up 11% in the quarter. International bookings were driven in part by over a billion dollars in international awards in mission systems. Also in the quarter, Poland signed a $745 million letter of acceptance for 200 Argum ER missiles adding to the growth potential for our defense systems business. We continue to see a broad pipeline of opportunities in the areas of air and missile defense, airborne ISR and C2 systems, and ammunition across multiple markets including newly emerging opportunities in the Middle East. Our strategy is to compete and win in global markets through technology differentiation. Bringing innovation and capability beyond what commercial alternatives can provide. To further our ability to innovate and deliver we invested $13.5 billion in R&D and infrastructure. As a result, we now have the ability to scale, design, and produce while fielding new capabilities at speed. We also have a track record of delivering defense technology that stays ahead of the pacing threats. For example, our technology is inside 90% of US national security space satellites. We're a leader in low observable technology, having produced the first stealth bomber, the B-2, and now its successor, the B-21. We've delivered more than 1.3 million solid rocket motors, and we are a leader in mission systems where we produce over a million secure microchips per year, some of which are a thousand times faster than the microchips in your smartphone. As we look to the future, we are leveraging our own hardware and software capabilities to develop the next generation of systems and we're also partnering with leading companies in areas such as AI. To ensure our customers have the most advanced capabilities. In the world. In conclusion, given our key franchise program, record backlog, strong competitive position, and global market dynamics, we continue to project significant potential ahead. Our focus remains on our strategy of driving innovation, expanding our market presence, and optimizing performance to deliver profitable, sustainable growth. We are committed to our long-term vision of creating value for our shareholders meeting our customer needs, and staying ahead in an ever-evolving global market landscape. So with that, I'm gonna turn the call over to Ken to discuss our first-quarter results and our updated guidance. Ken?
