- #Ammonium Perchlorate Bottleneck
- US munitions stockpiles have significantly declined since the Cuban Missile Crisis, with estimates suggesting depletion within days in a major conflict.
- Ammonium perchlorate (AP) is a critical bottleneck in solid rocket motor production, with only one US producer (American Pacific Corporation) as of May 2026.
- Solid propulsion missiles dominate US defense due to storability and safety, but their production relies on a fragile supply chain concentrated in a few companies.
- Liquid propulsion offers advantages like throttling, higher performance, and a more scalable supply chain using widely available hydrocarbon fuels and hydrogen peroxide.
- Hybrid propulsion combines solid fuel with liquid oxidizer but faces combustion instability and regression rate challenges.
- Air-breathing missiles (ramjets/scramjets) offer high specific impulse but require solid boosters, still depending on AP.
- Gel propellants provide throttleability but face toxicity and immaturity issues.
- Key industry players include L3Harris (solid motors), Northrop Grumman (prime and propulsion), and neoprimes like Anduril, Castelion, Galadyne, X-Bow, and Ursa Major.
- Scaling missile production requires addressing AP bottlenecks, with liquid propulsion seen as the most viable near-term solution due to faster scaling and commercial supply chains.
