Lockheed Martin has been awarded a contract to integrate the Patriot missile, an Army missile interceptor, into the US Navy’s Aegis combat system, a milestone the company said on Tuesday marks the first time the weapon will be fielded at sea.

Reuters was first to report in October 2024 that the Navy was moving forward with plans to arm its vessels with Patriot Advanced Capability-3 Missile Segment Enhancement (PAC-3 MSE) interceptors, driven by fears that China would deploy hypersonic weapons to sink ships in the Pacific.

The deployment will strengthen the missile defense shield protecting the Navy’s fleet of destroyers. Lockheed Martin has pursued the integration for several years, but the new contract marks the first concrete step toward fielding the Army interceptor on Navy surface ships. The rationale for the move has been building for years. As Reuters reported in 2024, PAC-3s are more agile than existing Navy interceptors, and their “hit to kill” concept – in which the missile strikes its target directly rather than exploding nearby – makes it particularly lethal against high-speed maneuvering ballistic missiles.
