Pentagon quadruples interceptor output to refill a drained magazine
SM-6 funding leaps to over $8.5B and a terminated SM-3 line is restored — but full depth won't return before 2028
Summary
Stung by the Iran-war drawdown, the Pentagon is surging interceptor production. SM-family funding jumps from $1.26B to $8.5B between FY26 and FY27; RTX plans to lift SM-6 output above 500 units a year — fourfold its ~125 baseline — while accelerating SM-3 IB and IIA, and a previously terminated SM-3 IB line has been restored to procurement. The MDA funded 25 SM-3 in its FY26 base request plus 12 from reconciliation, with 114 of 136 SM-3 IIAs paid via the reconciliation bill ($4.2B). Yet the timeline is unforgiving: officials say pre-2025 magazine depth won't return until 2028–29, constrained by testing capacity, qualification cycles and Chinese-controlled critical minerals. The Patriot and THAAD holes drive the same push.
By the numbers
- $1.26B → $8.5B — SM-family funding, FY26 to FY27.
- 500+/yr — RTX's SM-6 target, up 4x from ~125 baseline.
- 114 of 136 — SM-3 IIAs funded through reconciliation ($4.2B).
- 2028–29 — earliest restoration of pre-2025 magazine depth.
Why it matters
Money is the easy part; throughput is the constraint. The two-to-three-year lag between spending and missiles means the US carries a thin magazine through a period of acute great-power and regional risk — and allied rebuilds compete for the same lines.
What to watch
- Whether RTX hits the 500/year SM-6 and accelerated SM-3 marks on schedule.
- Critical-mineral supply (gallium/germanium) as a throughput limit.
- FY27 appropriations sustaining or cutting the surge.
