Farnborough 2026 Sees Introduction Of Affordable Air Defence Solution

Lockheed Martin has unveiled its Patriot Advanced Capability-3 Adapted Capability Effector (PAC-3 ACE) interceptor at the Farnborough International Airshow 2026. The PAC-3 ACE is designed to be a low-cost solution, with a cost per unit less than half that of the PAC-3 Missile Segment Enhancement (MSE) interceptor. The new interceptor is intended to counter airbreathing and cruise missiles, as well as close-range and short-range ballistic missiles. Lockheed Martin plans to collaborate with US and European companies to speed production, and the PAC-3 ACE will work with existing systems such as Raytheon’s PAC-3 fire control system and Northrop Grumman’s Integrated Battle Command System. This development was first reported by Janes.
