About this update from Lockheed Martin Corporation

DALLAs, Aug. 2 8 , 2026 - Lockheed Martin (NYSE: LMT) has successfully tested its new Joint Reduced Range Rocket (JR3) solution for the second time, a n affordable training round with a reusable launch pod designed to replace the current Reduced Range Practice Rocket for the U.S. Army and global partners. During a flight test conducted at Yuma Proving Ground, Arizona, Lockheed Martin successfully launched multiple training rounds demonstrating range, trajectory , accuracy and marking payload effects. What's New Second flight test: JR3 rounds launched from a HIMARS at Yuma Proving Ground , validating range , accurac y and marking payload . Designed for HIMARS | M270 : The ne w all-up round and 24-rocket launch pod supports launcher crews training in different environmental conditions , enabl ing high - volume live fire s . Reusable and affordable: B uilt on mature rocket m otor technology , our modular solution has a low-cost motor an d adaptable payload for cost - e ffective, repeatable training cycles. Why it Matters Higher - training volume: Launcher crews can conduct realistic live - fire drills on constrained ranges, day or night, across multiple locations . Cost savings: Our solution offers lower expense - per - round , with reloadable launch tubes and the ability to reuse the launch pods . Expert Perspective "Our new training round offers a scalable, very affordable solution built on mature rocket motor technology," said Dave Griser, vice president , Lockheed Martin Precision Fires Rockets . "With a 24 - round rocket launch pod , our JR3 s ystem meets the Army's demand for higher training volume and lower cost without sacrificing performance." What's Next Next flight test : Another JR3 flight test is planned later this year to further validate performance. Scalable to future programs: Our JR3 architecture and technology can be transferable to future evolutionary efforts like the Army's Direct Support Fires Technology initiative for mass produced low - cost , direct - fire rockets.
