# US Defense Contractors Secure Massive AI and Submarine Deals Amid Naval Tech Overhaul

Major US defense and aerospace contractors are capitalizing on a heavy pipeline of government spending in 2026, locking in billions of dollars in long-term commitments as the Pentagon accelerates its push for next-generation naval and aerial technologies.

RTX (RTX.US) has demonstrated significant momentum across its subsidiaries this August. Pratt & Whitney secured a USD 1.3 billion sustainment contract for F135 engines, while Raytheon landed a USD 745 million deal for SM-3 IIA interceptors alongside a seven-year Tomahawk cruise missile agreement. Crucially, Collins Aerospace completed high-altitude testing for the F-35's new cooling system (EPACS), a vital engineering step to manage the intense power and thermal loads anticipated in future fighter upgrades.

The scale of naval investments remains staggering. General Dynamics (GD.US) secured a massive USD 76.6 billion Navy contract via its Electric Boat division for the construction of 14 submarines, a move that guarantees extensive backlog visibility for years to come. The conglomerate's IT division also pulled in a USD 1.3 billion enterprise network and cybersecurity contract for the Army National Guard. On the executive front, GD announced that Senior Vice President Greg Gallopoulos will officially step down at the end of 2026.

Meanwhile, Huntington Ingalls Industries (HII.US) is aggressively modernizing its manufacturing capabilities. The shipbuilder signed a novel automation agreement in August—potentially worth up to USD 900 million over seven years—incorporating AI-driven physical automation from GrayMatter Robotics and Path Robotics into US Navy shipbuilding programs. Beyond completing acceptance trials for the aircraft carrier John F. Kennedy (CVN 79), HII’s Mission Technologies division was awarded a USD 2.2 billion STRINGRAI task order to support Southern Command surveillance operations.
