Leidos joins US Army's Reveille Forge, a "permanent hackathon" for early tech integration testing

Leidos is taking part in Reveille Forge, the US Army's new permanent integration and testing environment, to help spot technology integration problems sooner. The Army set up the site after its Operation Jailbreak exercise earlier this year. Reveille Forge replaces periodic events with a continuous "integrate-first" approach. Government, industry, and academia can test how technologies work together before they reach soldiers in the field. Leidos recently completed Jailbreak Sprint 1.5 at Redstone Arsenal in Alabama. It followed the first sprint at Fort Carson, Colorado, in June, where the company tested its IFPC Inc 2, MXR, and ALPS systems. "Now, Reveille Forge gives the Army and industry an enduring environment to integrate early, test together and mature capabilities faster," said Matt Becker, a Leidos vice president.

Leidos picks X-Bow to supply rocket motors for US Army's low-cost cruise missile

X-Bow Systems, a US maker of solid rocket motors, has been selected by Leidos to develop and produce booster motors for the US Army's new Low-Cost Containerized Munition (LCCM), a low-cost cruise missile. The company announced the deal on October 12, 2026, at the Association of the United States Army annual meeting in Washington. X-Bow will handle design, qualification testing, and static fires before full-rate production in 2027. Leidos will build the munitions in large quantities under the Department of War's "Arsenal of Freedom" initiative. "Modern conflict is decided by how many rounds you can put downrange, not how exquisite each one is," said chief executive officer Jason Hundley. It is the sixth new propulsion program X-Bow has won in 2026. The company recently completed its first major production contract, delivering more than 2,100 rocket motors.
