"PAC-3 Edge is designed to go after the most stressing targets that we — and, more importantly, that the Department of War — believes are the next-generation [threats] that they’re going to be seeing in the fight from our adversaries," Tim Cahill told Breaking Defense ahead of the Association for the US Army conference.
Tim Cahill and Lockheed's PAC-3 Edge reveal
Lockheed Martin unveiled the PAC-3 Edge today as its entry for the Army’s Future Interceptor program, positioning the design as a next-generation successor to the current PAC-3 missile segment enhancement (MSE). Tim Cahill, president of Lockheed’s missiles and fire control unit, said the company is one of two firms selected to advance in the Army’s Future Interceptor effort, though he did not name the other competitor and the Army did not respond to a request for more information.
Lockheed plans to present a full-scale model of the new interceptor at the Association for the US Army conference on Monday, the company said.
Performance claims: range, altitude, seeker sensitivity and maneuverability
Cahill described PAC-3 Edge as longer ranged and able to operate at higher altitude than the legacy PAC-3, with enhanced ability to engage targets attempting to hide. He said the missile will include a seeker with "greater sensitivity" and a greater capability to maneuver and respond to threats. Lockheed framed these capabilities as responses to what it called "next-generation" threats identified by the Department of Defense.

End the scrambleSeeker development: in-house work and heavy investment
Lockheed said it is developing the PAC-3 Edge seeker in-house and intends to reuse the technology across other offensive and defensive systems. The company plans roughly $800 million of investment into the seeker and has already put "several $100 million dollars" into it; overall missile investment from Lockheed, Cahill said, will total "hundreds of millions of dollars" beyond the seeker work. Cahill also said Lockheed has already invested "somewhere between $50 [million] and $100 million or better" into PAC-3 Edge development.
Three-pulse motor and industrial partnerships
For propulsion, Lockheed is collaborating with Northrop Grumman on a three-pulse solid rocket motor intended to provide greater range and altitude compared with the legacy PAC-3 missile, Cahill said. Separately, Lockheed noted progress with a partnership announced in 2024 with General Dynamics to expand solid rocket motor production for other systems: that collaboration produced a motor firing "in the last few days," according to Cahill.
Camden, Ark. production line and factory modernization
Lockheed intends to manufacture PAC-3 Edge on its existing PAC-3 line in Camden, Ark. The company said it is currently ramping PAC-3 MSE production under an agreement with the Pentagon to triple interceptor output over the next seven years. To support higher rates and future Edge production, Lockheed is building a new MSE production facility equipped with robotics, automation and artificial intelligence to boost manufacturing efficiency; PAC-3 output will move to the new facility when complete, and the legacy plant will receive the same upgrades.
How the Army, Lockheed, and Congress are positioned
- The Army: The PAC-3 Edge is tied to the service’s Future Interceptor program, a follow-on to earlier efforts. The Army previously canceled the Lower-Tier Future Interceptor (LTFI) in 2024, though Maj. Gen. Frank Lozano, then the program executive officer for missiles and space, said in October 2025 that aspects of LTFI were "somewhat pre-decisional" and that he believed the program could move to program-of-record execution within a year.
- Lockheed Martin: The company is committing substantial internal funds to development and is already accelerating factory investments and supplier partnerships. Lockheed said it received undefinitized contract actions (UCAs) from the department to ramp PAC-3 and Terminal High Altitude Area Defense production and believes the UCAs provide the contractual authority needed to proceed while final contract definitization follows.
- Congress and budgeters / foreign buyers: Lockheed acknowledged that eventual congressional appropriations will be required to sustain production increases, but suggested that foreign military sales contracts and current domestic orders could help bridge short-term budget timing issues while lawmakers work out funding.
Lockheed intends to begin testing PAC-3 Edge in 2027 and aims for first deployment in 2031. Earlier this year the company also announced PAC-3 ACE, a lower-cost, less capable MSE variant for international customers. The immediate next public milestone is the full-scale model showing at AUSA; the program’s path through testing, formal Army decisions, and congressional appropriation will determine whether PAC-3 Edge moves from company prototype to fielded interceptor on the timeline Lockheed has outlined.
