Lockheed Martin completes second successful JR3 training rocket flight test at Yuma Proving Ground

(AWP Alliance News) - Lockheed Martin reported a second successful flight test of its Joint Reduced Range Rocket, an affordable training round with a reusable launch pod intended to replace the US Army's Reduced Range Practice Rocket. The test at Yuma Proving Ground in Arizona launched multiple rounds from a HIMARS launcher, validating range, trajectory, accuracy, and marking payload effects.

The system uses a new all-up round with a 24-rocket pod designed for HIMARS and M270, targeting higher-volume live-fire training on constrained ranges. Another flight test is planned later this year as Lockheed Martin positions the architecture for potential use in future low-cost rocket programs.
