The U.S. government announced a contract with Lockheed Martin for the development, integration and testing of PAC-3® Missile Segment Enhancement (MSE) into the Aegis Combat System. This move places the U.S. Navy among the ranks of PAC-3 MSE users around the world, including the U.S. Army and 16 partner nations, giving U.S. Navy warships a razor-sharp defense that helps keep America’s freedom of the seas unchallenged.
AC-3 MSE is combat proven in real-world operations and is a key IAMD capability for the U.S. and its allies. The U.S. government awarded Lockheed Martin a multi-million contract to continue munitions acceleration efforts and deliver a record number of PAC-3 MSE interceptors in 2026. This contract builds on the framework agreement Lockheed Martin signed with the U.S. Department of War to rapidly accelerate the production and delivery of PAC-3 MSE in support of the Arsenal of Freedom.
By integrating PAC‑3 MSE’s capabilities into Aegis, the Navy is taking a decisive step forward in defending America’s fleet and our global interests against the most advanced threats,” said Jason Reynolds, vice president and general manager, Lockheed Martin IAMD. “Lockheed Martin is driving the innovation behind this effort—bringing together advanced, combat‑proven systems in new ways to accelerate capability and deliver a decisive advantage in maritime defense.”
“This integration further expands the capability of Aegis to engage missile threats at multiple layers, enabling a more comprehensive and effective defense against evolving threats, ensuring the warfighter has the strategic advantage,” said Chandra Marshall, vice president, Lockheed Martin Multi-Domain Combat Solutions.
