Why It Matters

RTX Corp. is lobbying on the National Defense Authorization Act and appropriations bills amid unprecedented congressional urgency around missile defense. The U.S. faces a critical hypersonic weapons gap: Russia’s Oreshnik travels at Mach 10 and China’s GDF-600 outpaces American capabilities.

This geopolitical pressure has driven record defense spending, with Congress authorizing $900.6 billion for FY2026—$8 billion above Pentagon requests—explicitly prioritizing missile defense modernization. RTX’s challenge is navigating a competitive lobbying landscape while securing sustained funding and production commitments for its PATRIOT air defense systems and next-generation missile defense platforms.

RTX’s strategy leverages Cornerstone’s six seasoned lobbyists, including personnel with direct Senate Armed Services Committee and House Armed Services Committee experience, positioning the company to influence both authorization language and appropriations earmarks.

By the Numbers

RTX Corp. has deployed a multi-firm lobbying strategy since 2020, spending approximately $86.5 million across internal and external advocacy. The company’s in-house operation accounts for nearly $73 million of that total.

RTX engaged Cornerstone Government Affairs Inc. for $60,000 in the last quarter of 2025. Other key firms include American Defense International Inc. ($1.46 million), Invariant LLC ($1.57 million), and Akin Gump Strauss Hauer & Feld LLP ($1.38 million).

Cornerstone provides access to defense experts including Anthony J. Lazarski, who brings 8.5 years on the Senate Armed Services Committee, and Jessica Searle Calio, a former House Armed Services Committee military legislative assistant.

The Agenda

The aerospace giant targets legislation funding its core programs: PATRIOT air defense systems, F-35 fighter jet components, and next-generation missile defense systems. The Senate’s FY2026 NDAA authorization of $900.6 billion—$8 billion above administration requests—directly supports RTX’s business areas.

Broader Context

RTX’s Q4 2025 lobbying engagement occurs within a highly favorable environment for defense contractors. Geopolitical pressures amplify congressional urgency—Russia’s Oreshnik hypersonic missile and China’s GDF-600 create sustained demand for advanced air and missile defense systems.

Global demand is unprecedented. Spain awarded RTX a $1.7 billion Patriot contract in December 2025, while Romania placed a second order within one year. Ukraine continues receiving PATRIOT systems, with congressional provisions extending the Ukraine Security Assistance Initiative through 2028.

Production bottlenecks and workforce shortages favor contractors securing legislative support for multi-year contracts. The Trump administration signals 15 percent defense spending increases in FY2026, though it has threatened specific contractor actions, increasing the value of direct legislative relationships.

Between The Lines

Congress is moving aggressively on defense spending benefiting RTX’s core business. The Senate’s $900.6 billion FY2026 National Defense Authorization Act fully funds missile defense modernization and F-35 production.

Russia’s Oreshnik hypersonic missile creates Congressional urgency around air defense systems. RTX’s PATRIOT system has successfully intercepted Russian hypersonic weapons in Ukraine, validating lawmakers’ priorities. International orders accelerated with Spain’s 1.7 billion Patriot contract and Romania’s $168 million order.

Competitive Landscape

The FY2026 National Defense Authorization Act has attracted lobbying from 375 organizations, reflecting intense competition among defense contractors.

RTX faces direct pressure from other major firms lobbying on identical issues. Boeing Co. and General Dynamics Corp. also retain Cornerstone, creating overlapping access strategies. Individual members like Rep. Aaron Bean (R-FL) secured $9.4 million for RTX’s Collins Aerospace subsidiary, demonstrating how member-directed funding can bypass broader lobbying efforts.

The Bottom Line

RTX hired Cornerstone for $60,000 in the last quarter to lobby on defense authorization and appropriations, supplementing its $86.5 million lobbying operation since 2020. The timing aligns with congressional debate over the FY2026 National Defense Authorization Act, which directly funds RTX’s missile defense and fighter aircraft programs. Congressional focus on strengthening U.S. missile defenses against hypersonic threats creates favorable conditions for RTX’s legislative priorities.
