Lockheed Martin Introduces PAC-3 ACE, a Lower-Cost Interceptor

Lockheed Martin used the Farnborough International Airshow on July 20, 2026 to unveil two new air-and-missile-defense products aimed at a market it says is being reshaped by drone warfare and interceptor shortages: PAC-3 ACE (Adapted Capability Effector), a lower-cost interceptor for the Patriot air-defense system, and MORFIUS X-Rotor, a reusable counter-drone weapon.

Lockheed says PAC-3 ACE will cost less than half of what a PAC-3 Missile Segment Enhancement (MSE) interceptor costs, a unit that has run around $4 million, while remaining compatible with the existing Patriot weapon system and the Integrated Battle Command System. The interceptor is built on the proven PAC-3 fire-control architecture and is designed to counter airbreathing threats such as cruise missiles alongside short- and close-range ballistic missiles, with Lockheed targeting initial production within about 36 months and joint development alongside American and European partners.

Alongside PAC-3 ACE, Lockheed detailed MORFIUS X-Rotor, a ground-launched, field-reusable high-power-microwave system it says can disable more than 50 hostile drones in a single flight without relying on a dedicated fire-control radar, part of the Pentagon's 2025-2028 Rapid Response Counter-UAS Roadmap. The dual announcement follows a stretch in which US and allied forces have burned through expensive interceptor stockpiles against far cheaper threats, with reports noting a roughly $4 million PAC-3 has at times been used against Iranian-made drones that can cost around $35,000, and comes about three months after the Pentagon awarded Lockheed a $4.7 billion contract in April 2026 to accelerate PAC-3 MSE production.

For LMT, a genuinely cheaper interceptor could widen margins on future Patriot orders or let allied buyers stretch existing budgets into larger stockpiles, though neither PAC-3 ACE nor MORFIUS X-Rotor has a disclosed government contract or firm delivery date yet, so the near-term revenue impact is not quantifiable from this announcement alone. Investors could watch for a formal Army or NATO-partner order, plus progress against the roughly 36-month production timeline, as the next concrete signals of whether these programs convert the drone-defense narrative into booked revenue rather than remaining a trade-show unveiling.
