• The US faces a munitions stockpile crisis due to high costs and low production rates.
• New entrants are developing low-cost, high-volume munitions using commercial supply chains.
• Legacy munitions are expensive, with some costing $2-4 million per unit.
• The Pentagon is shifting towards low-cost alternatives, with some new programs capping costs at $300,000 per round.

The US munitions affordability crisis may indicate a need for a strategic shift towards low-cost, high-volume production. New entrants could disrupt the traditional defense industry, offering affordable solutions that may change the dynamics of military procurement. This could suggest a move towards more cost-effective and sustainable defense spending, which may benefit the US and its allies in the long run.
