The United States Navy has asked for funding in the Fiscal Year 2027 budget to procure 676 Standard Missile series interceptors, comprising 136 RIM-161D SM-3 IIA Block IIAs and 540 RIM-174 SM-6 missiles. This purchase signals a sustained modernization of the Navy's shipboard air defense posture and a focus on expanding engagement options against anti-access/area denial — and potential long-range missiles. The exact block/iteration details for the SM-6s were not fully enumerated in the initial budget summary, but the total count emphasizes an aggressive build-out of the naval surface-to-air defense layer.
