The PAC-3 Adapted Capability Effector is designed to defeat several threat types. Those include airbreathing threats, cruise missiles, and close-range and short-range ballistic missiles.
Lockheed Martin is positioning PAC-3 ACE as a complementary effector for allied air defenses. The company said it can be fielded quickly and add magazine depth.
The interceptor is built on the proven PAC-3 fire control system. It is fully linked to the Patriot weapon system and the Integrated Battle Command System.
That architecture is intended to shorten development, testing and deployment timelines. It also allows allied forces to field a common interceptor across the PAC-3 network.
Lockheed Martin said PAC-3 ACE is meant to reduce cost-per-kill. The company also said it will retain the reliability associated with PAC-3 systems.
The program will include American and European industry partners and suppliers. Lockheed Martin said that approach will improve the resilience of the U.S. defense industrial base worldwide.
The allied production model is also tied to transatlantic defense cooperation. Lockheed Martin said joint development and production with European partners would support interoperability.
“American and allied warfighters need a solution that is battle-tested and budget-smart, and PAC-3 ACE delivers exactly that by building on the unrivaled performance of the PAC-3 MSE,” said Tim Cahill, president, Lockheed Martin Missiles and Fire Control.
“As we look to partner with our allies, we can further enhance resiliency and ensure our forces can swiftly counter emerging threats today and tomorrow.”
The announcement places PAC-3 ACE inside a wider push for cheaper air defense capacity. Lockheed Martin framed the interceptor as a faster path to stronger Patriot-linked missile defense for U.S. and allied forces.
The system also reflects a growing demand for interceptors that can be bought and deployed at scale. For allied militaries, the stated aim is simple: more shots available against more threat types at a lower unit cost.
