			Why it constrains
Ammonium perchlorate	Material	Critical	AMPAC's Cedar City plant is the only DoD-approved domestic source of AP for weapons motors. Northrop Grumman was approved as an alternative source for space launch in 2021. AMPAC is adding a line to raise capacity by more than 50%.
Energetic materials	Material	Critical	Propellant and explosive supply has many single-source nodes. Ammonium perchlorate for weapons motors has one DoD-approved domestic source (AMPAC in Cedar City, Utah), and DoD calls single-source reliance a resilience risk.

Criticality is how much a shortage would constrain production; open an input for producers, concentration and trade controls.
