Lockheed Martin unveils the PAC-3 Edge defensive interceptor.

Lockheed Martin introduced PAC-3 Edge, describing it as a missile-defense interceptor for advanced threats, including hypersonic missiles. The company said the design combines a new seeker and upgraded flight controls with a Northrop Grumman multi-pulse rocket motor.

Tim Cahill, head of Lockheed Martin's missiles and fire-control business, told Reuters that the interceptor should cost about as much as the existing PAC-3 MSE and could eventually be produced at roughly 2,000 units a year. Those cost and production figures are company projections rather than completed program results.
