DIRECT TO PHASE II: Extended Range 10-inch Air Launched Rocket
SBIR Opportunity Analysis
The U.S. Navy is offering Direct to Phase II SBIR topic DON26BZ01-DV001 to integrate Highly Loaded Grain propulsion technology into existing 10-inch rocket motors in order to improve range, performance, and tactical flexibility. The work centers on developing, documenting, fabricating, and validating a tactical solid rocket motor, including ballistic modeling with Government-furnished CLWire software, thermal and structural design, nozzle and igniter development, propellant casting, and static fire testing. Key context includes a 10-inch tactical casing based on the HARM aft-end structure, an expected total impulse increase of about 30 percent over the legacy baseline, support for both all-boost and boost/sustain thrust profiles, and the possibility that later work may become classified, with U.S.-owned and operated contractors able to obtain and maintain secret clearances. The topic is pre-release, opens on May 6, 2026, and the application due date is June 3, 2026 at 4:00 PM UTC.
