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.
