Thank you, Kathy, and good morning, everyone. I'll begin my comments with top-line results for the quarter. As shown on slide four in the earnings deck, second-quarter sales were $10.4 billion, up 1% year over year. Sequentially, Q2 sales were up 9% compared to Q1, with all segments contributing to this meaningful growth. Our organic sales were $10.3 billion, up 2% year over year, reflecting the divestiture of the training services business which closed ahead of schedule at the end of May. Aeronautics second-quarter sales increased by 2% year over year, due to higher volume on B-21 and TACOMO, partially offset by lower restricted sales. At DS, sales grew by 7% on a GAAP basis, driven by the Sentinel program, from higher ammunition sales. The training services business generated $40 million of sales in Q2 before the transaction closed. So on an organic basis, DS sales increased 9% compared to the prior year. Mission Systems was our fastest-growing segment in Q2, with sales up by 14% year over year. This was driven in part by liquidation of inventory on restricted awards which we had originally expected in Q1, and higher volume on marine programs. At Space, Q2 sales were lower primarily due to the previously communicated wind-down of work on two programs, reflecting $283 million of year-over-year headwinds. Turning to slide five, operational performance for the quarter was strong. Segment operating income was higher by 11% compared to Q2 of last year, and our segment operating margin rate increased 100 basis points year over year to 11.8%. AS operating income was up 3% compared to the prior year, with a Q2 operating margin rate of 10.3%. This portfolio continues to have a mix of mature production programs and newer development programs, and with coupled with strong program execution and disciplined cost management, it provides a formula for AS to deliver healthy margin rates. Defense Systems had a standout quarter of margin performance, with the Q2 margin rate improving to 12.7%. This performance was driven by the recognition of a favorable EAC adjustment on the E&D phase of the Sentinel program, primarily based on expectations for achieving certain contract incentives. Mission Systems' second-quarter margins expanded to 14%, and operating income increased 22% year over year. This quarter's margin reflects improved production efficiencies and performance across airborne radar programs. At Space Systems, operating income dollars were reflective of the lower sales volume, partially offset by improved program performance. Operating margin rate was 10.6%, up 50 basis points from Q2 of last year, driven by higher net EAC adjustments. Moving to earnings per share, slide six shows year-over-year EPS comparison. In total, second-quarter diluted earnings per share was $8.15, an increase of 28% compared to the second quarter of 2024. This was driven by two factors: higher sales and improved segment performance, which contributed $0.80 of year-over-year benefit, and a gain of $1.04 recognized on the divestiture of the training services business. Next, I'll provide updates on our forward outlook, starting with segment-level guidance on slide seven. For sales, we are maintaining our top-line outlook at AS and DS of low $13 billion and low $8 billion respectively. Aeronautics sales reflect mid-single-digit annual growth, driven by the continued ramp on B-21 and TACOMO, as well as higher volume on F-35 and D2. We continue to expect DS will achieve double-digit sales growth this year, driven by Sentinel, IVCS, and higher volume in our weapons business stemming from 2024 award volume. At Mission Systems, we are increasing our sales expectations to low to mid $12 billion, based on the strength of their year-to-date results and continued growth on domestic and international programs throughout their portfolio, including airborne and ground-based radar, EW, and restricted programs. At Space, we now project sales of mid to high $10 billion, reflective of the award decision on the ESS program. With respect to operating margin rate, we are maintaining our margin rate expectations for AS, MS, and Space. At DS, we are increasing our margin rate expectations to mid-10%, based on their notable Q2 results. At the company level, as shown on slide eight, we are narrowing the range of our top-line outlook and expect organic sales growth of approximately 3% for the year. Our outlook projects sales in the second half of the year to be higher than in the first half by approximately $2.5 billion. This increase in revenue is driven by a few factors. First, we expect the TRIAD programs on B-21, Sentinel, and Columbia to collectively deliver roughly $750 million in higher second-half sales. B-21 LRIP lot three and lot five advanced procurement are expected to be awarded in Q4. These awards will also include a significant amount of revenue recognition due to inventory liquidations for materials purchased to support production schedules. Meanwhile, the Sentinel and Columbia programs are expected to continue to ramp, including higher material receipts and subcontractor deliveries in the second half of the year. Another element of second-half growth is the ramp on new recently awarded programs, including TACIMO, IBCS, international ground-based radars, and multiple ammunition programs. Collectively, these new programs are expected to contribute nearly $700 million of higher second-half sales. Lastly, Q4 has historically been our strongest quarter of revenue generation, driven by production schedules and timing of materials. We expect this normal seasonality to continue this year, contributing roughly $1 billion of higher second-half sales. Altogether, we expect Q3 sales to be up 3% to 4% compared to Q2, with further acceleration in Q4, positioning us to deliver on our full-year sales guidance. For segment operating income, we are increasing the guidance range by $50 million at the midpoint, driven by higher margins at DS that I previously described. This reflects the company-level segment OM rate of almost 11.4% in the second half. I reemphasize that excluding the B-21 EAC adjustment in Q1, first-half margins were also 11.4%. MS is expected to be the driver of margin dollar growth in the second half. The MS profile is enabled by continued strong program performance, higher international sales, and seasonal volume increases to higher margin production later in the year. With respect to earnings per share, we are increasing our guidance range driven by higher segment operating income. This increase in operational performance is being partially offset by nonoperating items. While the reconciliation bill recently signed into law includes several provisions that benefit cash flow, it also modifies the treatment of certain R&D tax credits that increase our estimated tax rate. As a result, we now expect a tax rate of high 17% for the year. Given the bill was approved in July, we expect an effective Q3 tax rate of approximately 21% to reflect the cumulative impacts to date. We are reaffirming our guidance for corporate unallocated expenses and expect roughly $100 million of expense in both Q3 and Q4 due to timing of state taxes and normal seasonality. Taking all those elements into account, we are increasing our EPS guidance by $0.05 and now expect a range of $25 to $25.40. Lastly, with respect to cash, we are increasing our 2025 guidance range and now expect free cash flow of $3.05 billion to $3.35 billion. This increase is driven by the revision to section 174 in the tax code related to the treatment of R&D expenditures, partially offset by the application of the corporate minimum tax. In the quarter, we generated $637 million in free cash flow, a significant improvement compared to the first quarter. We continue to expect the largest quarter of cash generation in the fourth quarter, consistent with our seasonal pattern and sales ramp. In addition, there are a few other unique items driving higher Q4 cash flows. First, as previously noted, reduced cash tax payments this year. Second, we have a higher than average level of milestone payments in the second half, including contract closeout payments at Space. Lastly, we expect a significant benefit from inventory liquidations, particularly in Aeronautics in Q4. In summary, we had an outstanding quarter of operational financial performance. Sales, margins, earnings per share, and cash all increased neatly from Q1, with momentum that we expect to continue in the second half of the year. These results demonstrate the value of the Northrop Grumman portfolio as well as our continued focus on disciplined program performance. We remain focused on delivering on our full-year commitments while executing our business strategy and deploying our capital in value-creating ways. With that, we'll open the call to questions. Thank you.
