Thanks Jim, and good morning, everyone. Today, I will walk you through our consolidated and business area results for the first quarter and cover our 2023 outlook. As I highlight our results, please follow along with the web charts we have posted with our earnings release today. Let's begin with chart three and an overview of consolidated financial results. Overall, 2023 is off to a solid start, positioning us well to meet our commitments for the year. We delivered just over $15 billion in sales with $1.7 billion in segment operating profit, resulting in 11.1% segment operating margin. Earnings per share was $6.61 and we generated $1.3 billion of free cash flow, enabling a solid shareholder return to share repurchases, and dividends. Our book-to-bill ratio for the first quarter was 0.7 as anticipated. With backlog expected to increase in the second quarter, from the upcoming order for F-35 Lot 17 production. And we continue to strategically invest in our growth strategy with $600 million of capital expenditures and independent research and development this quarter. These financial results are on track with our expectations for the year. Taking a closer look at the quarter's results with consolidated sales and segment operating profit on chart four, first quarter sales increased year-over-year by 1% as space led the way with 16% growth. Segment operating profit was down 2% as lower ULA equity earnings and contract mix more than offset the benefits from slightly higher volume and step ups. As expected, margins contracted mostly due to the lower equity earnings from ULA. Moving to earnings per share on chart five. GAAP earnings per share were up $0.17 or 3% over 2022. Adjusted for mark-to-market investment gains, EPS was flat. On an adjusted basis, the unfavorable year-over-year impacts from segment operating profit, interest expense and FAS/CAS pension income were offset by the lower share count. Moving to cash flow on chart six, we generated nearly $1.3 billion of free cash flow in the quarter, including nearly $300 million of capital expenditures, as well as over $600 million of accelerated payments and continued support of the supply chain. Our cash deployment plan is on track, which we expect to accelerate throughout the year. In the quarter, we had $500 million of share repurchases and paid almost $800 million in quarterly dividends. Total cash return to shareholders in the quarter was 101% of free cash flow. Moving to segment results and starting with Aeronautics on chart seven. First quarter sales at Aero decreased 2% year-over-year. Lower F-35 production sales were partially offset by higher F-16 and classified program volumes. Operating profit was slightly lower than prior year as the impact from lower net profit adjustments and sales volume was partially offset by favorable contract mix. For the year, we expect F-35 deliveries to be lower than previously anticipated due to software maturation with the Tech Refresh 3 program and hardware delivery timing. We will refine the impact as the year progresses, but do not expect the change to Aero’s 2023 sales and profit ranges that we had previously communicated in January as we maintain our production cost throughput profile for the year. Looking at Missiles and Fire Control on page eight, sales decreased 3% as lower sales volume on sensors and global sustainment, as well as our tactical strike missile programs were partially offset by growth in integrated air and missile defense. Segment operating profit was down 2%, driven by lower sales volumes and net profit adjustments, partially offset by favorable contract mix. At Rotary and Mission Systems on page nine, sales were down 1% from 2022, driven by lower volume on Black Hawk production and our C6 ISR programs. These declines were partially offset by favorable volume on radar programs and integrated warfare systems and sensors. Including Defense of Guam, an important growth area for RMS that was won in 2022. Operating profit decreased 14%, due to lower sales volume and timing of net profit adjustments. Turning to chart 10 and our space business area. Sales were up 16% in the quarter driven by strong growth on the next gen interceptor and classified programs and further boosted by favorable program lifecycle timing on Orion, protective communications, and fleet ballistic missile programs. Operating profit was up 13%, driven by the increase in volume and favorable profit adjustments partially offset by the lower equity earnings from United Launch Alliance. Okay. Now shifting to the outlook for 2023 on page 11. For the year, we are reaffirming guidance for all key metrics. We continue to expect sales to be in the range of $65 billion to $66 billion with segment operating margin at 11.2% at the midpoint. We also still expect to deliver free cash flow at or above $6.2 billion, while repurchasing $4 billion of outstanding shares. We believe our first quarter results position us to achieve these expectations as we continue to add orders, we program execution commitments and pursue new opportunities throughout the year. Right, so let's close on page 12 to summarize with the comments. As noted, first quarter represents a solid start to 2023. We reaffirm key financial metrics as previously guided and continue to expect a return to growth in 2024 and beyond. With consistent free cash flow per share growth. Looking ahead, our strategic focus on 21st Century Security Solutions aligns with expected increases to defense and security spending. With our continued discipline and focus on execution, we are on track to meet our expectations for long-term growth and value creation for our shareholders. With that Lois, let's open up the call for Q&A.
