Anduril and Raytheon complete AFRL‑contracted static‑fire of Highly Loaded Grain SRM for air‑to‑air missiles

Anduril Industries and Raytheon (an RTX business) completed an AFRL‑contracted static‑fire test of a Highly Loaded Grain (HLG) solid rocket motor intended for air‑to‑air weapon systems. HLG architecture enables larger propellant volumes, higher specific impulse and tailored thrust profiles to extend engagement ranges by hundreds of kilometres.

Briefing

What Hype is tracking

  • The static‑fire validates an HLG SRM approach that increases propellant load and specific impulse to extend air‑to‑air engagement ranges into the "hundreds of kilometres" regime, directly addressing adversary over‑the‑horizon A2A threats and range shortfalls. See recent extended‑range SRM static fires (https://hype.aero/?story=4d16edae-e9c5-4040-8550-8cc2b94fbae6).
  • The test signals collaborative scaling of domestic propulsion capability under AFRL contracts and complements moves to shore up the SRM industrial base — including Pentagon efforts to expand U.S. solid rocket motor production capacity (https://hype.aero/?story=b4adab53-dd88-4dc9-a560-da56c1c30d06) and Anduril’s own SRM factory build‑out (https://hype.aero/?story=756c075a-7303-4673-8f33-77cc9a33296d).
