- U.S. DoD requests $1.04T FY2026 budget, driving defense sector growth amid geopolitical tensions and tech innovation.

- Leonardo DRS and Mercury Systems show strong Q1 2025 performance, aligning with DoD priorities in radar, AI, and secure systems.

- Companies benefit from $150B supplemental funding and long-term modernization trends like hypersonic tech and electric propulsion.

- Strategic spending and 11% cost increase by 2039 create durable opportunities for niche defense contractors with mission-critical capabilities.

The U.S. defense sector is entering a new era of strategic investment, driven by geopolitical tensions, technological innovation, and a renewed focus on military readiness. With the Department of Defense (DoD) requesting a staggering $1,042.6 billion in total funding for FY2026—including $892.6 billion in base budget authority and $150 billion in supplemental funding—the sector is primed for sustained growth US Defence Spending 2025–26: Full Budget Breakdown, [https://warfarenews.org/us-defence-spending-2025-26/][1]. This spending surge, coupled with long-term projections of an 11% cost increase over the next decade Long-Term Implications of the 2025 Future Years …, [https://www.cbo.gov/publication/61017][2], creates a fertile environment for defense contractors specializing in cutting-edge capabilities. Two companies standing out in this landscape are Leonardo DRS and Mercury Systems, whose recent financial performance and strategic positioning align closely with the DoD's modernization priorities.

Sector Momentum: A Perfect Storm of Demand and Innovation

The defense industry's momentum is underpinned by three key factors: geopolitical urgency, technological disruption, and capital efficiency. Global defense budgets grew by 9% in 2024, with the U.S. market projected to expand at a 3.58% compound annual growth rate (CAGR) through 2030 US Defense Industry - Military Market - Size, Share, Trends, [https://www.mordorintelligence.com/industry-reports/united-states-defense-market][3]. This growth is fueled by a shift toward next-gen technologies such as artificial intelligence (AI), hypersonic systems, and unmanned platforms. For instance, Palantir Technologies saw a 45% surge in government revenue in Q1 2025, driven by AI-powered battlefield analytics Defense Market Quarterly Review – May 2025, [https://defense-update.com/20250518_defense-market-quarterly-review.html][4], while Kratos Defense's hypersonic systems pipeline now exceeds $12.6 billion Defense Market Quarterly Review – May 2025, [https://defense-update.com/20250518_defense-market-quarterly-review.html][4].

The DoD's emphasis on “multi-domain deterrence” further amplifies demand for specialized industrial capabilities.

and , though smaller than industry giants like Lockheed Martin or Boeing, are uniquely positioned to capitalize on niche but high-growth segments of the defense ecosystem.

Leonardo DRS: A Powerhouse in Tactical Innovation

Leonardo DRS, a subsidiary of Italian industrial giant Leonardo S.p.A., has emerged as a critical player in tactical computing, radar, and electric propulsion systems. Its Q1 2025 results underscore its strong alignment with DoD priorities:
- Revenue rose 16% year-over-year to $799 million, driven by ground and naval network computing, tactical radars, and electric power systems Leonardo DRS Announces Financial Results for First Quarter 2025, [https://www.leonardodrs.com/news/press-releases/leonardo-drs-announces-financial-results-for-first-quarter-2025/][5].
- Bookings totaled $1 billion, with a robust book-to-bill ratio of 1.2x, and a record $8.6 billion backlog Leonardo DRS Announces Financial Results for First Quarter 2025, [https://www.leonardodrs.com/news/press-releases/leonardo-drs-announces-financial-results-for-first-quarter-2025/][5].
- Adjusted EBITDA grew 17% to $82 million, with the Integrated Mission Systems (IMS) segment delivering a 38% EBITDA increase Leonardo DRS Announces Financial Results for First Quarter 2025, [https://www.leonardodrs.com/news/press-releases/leonardo-drs-announces-financial-results-for-first-quarter-2025/][5].

Leonardo DRS's success stems from its focus on modernization programs that align with the DoD's 2025–2029 Future Years Defense Program (FYDP). For example, its electric propulsion systems are critical for next-gen naval vessels, while its tactical radars support the Air Force's need for advanced air defense. The company's reaffirmed 2025 guidance—$3.425–$3.525 billion in revenue and $435–$455 million in adjusted EBITDA—reflects confidence in its ability to scale amid rising demand Leonardo DRS Announces Financial Results for First Quarter 2025, [https://www.leonardodrs.com/news/press-releases/leonardo-drs-announces-financial-results-for-first-quarter-2025/][5].

Mercury Systems: Navigating Challenges with Strategic Resilience

Mercury Systems, a leader in secure RF and sensor processing technologies, has faced headwinds in recent years but is showing signs of recovery. Its Q1 2025 results highlight a turnaround:
- Revenue increased 13% to $204.4 million, with bookings of $247.7 million (a 1.21 book-to-bill ratio) Mercury Systems Reports First Quarter Fiscal 2025 Results, [https://ir.mrcy.com/news-releases/news-release-details/mercury-systems-reports-first-quarter-fiscal-2025-results][6].
- Adjusted EBITDA improved dramatically to $21.5 million, up from $2.0 million in Q1 2024 Mercury Systems Reports First Quarter Fiscal 2025 Results, [https://ir.mrcy.com/news-releases/news-release-details/mercury-systems-reports-first-quarter-fiscal-2025-results][6].
- A $12.3 million contract for avionics subsystems underscores its role in next-gen aircraft development Mercury Systems Reports First Quarter Fiscal 2025 Results, [https://ir.mrcy.com/news-releases/news-release-details/mercury-systems-reports-first-quarter-fiscal-2025-results][6].

Despite a GAAP net loss of $17.5 million, Mercury's focus on high-margin, mission-critical technologies positions it to benefit from the DoD's push for AI-integrated systems and secure communications. Its backlog of $1.34 billion, up 16% year-over-year, suggests strong near-term visibility Mercury Systems Reports First Quarter Fiscal 2025 Results, [https://ir.mrcy.com/news-releases/news-release-details/mercury-systems-reports-first-quarter-fiscal-2025-results][6].

Strategic Government Spending: The Catalyst for Growth

The DoD's FY2026 budget allocates significant resources to areas where Leonardo DRS and Mercury Systems excel:
- Hypersonic weapons and counter-hypersonic systems: Leonardo DRS's radar and sensor technologies are essential for detecting and neutralizing hypersonic threats.
- Cybersecurity and AI: Mercury's secure processing solutions are critical for protecting defense networks and enabling AI-driven decision-making.
- Electric propulsion and naval modernization: Leonardo DRS's electric power systems align with the Navy's goal to upgrade its fleet with energy-efficient, high-performance vessels.

According to the Congressional Budget Office (CBO), these modernization efforts will drive a 11% cost increase in DoD spending by 2039 Long-Term Implications of the 2025 Future Years …, [https://www.cbo.gov/publication/61017][2]. This long-term trend creates a durable tailwind for companies that can deliver scalable, mission-critical solutions.

Conclusion: A Compelling Case for Defense Innovation

Leonardo DRS and Mercury Systems exemplify the disruptive potential of industrial stocks in the defense sector. While Leonardo DRS benefits from its established backlog and alignment with high-priority modernization programs, Mercury Systems is leveraging its technical expertise to overcome past challenges and secure a foothold in next-gen defense technologies.

For investors, the key takeaway is clear: strategic government spending is not just a short-term boost but a long-term tailwind. As the DoD continues to prioritize innovation and readiness, companies like Leonardo DRS and Mercury Systems are well-positioned to deliver outsized returns.
