1R-1 PE0604932F Long Range Standoff Weapon. Annual appropriation, not lifetime development. FY2026 includes listed reconciliation spend-plan funds; FY2027 is requested funding. Not a contract award or recurring hardware price.
2MLRSO1: net procurement plus current-year advance procurement. Not the gross procurement line plus advance procurement, which would double-count prior advance funding.
Keep advance procurement and warhead development separate
The budget’s total obligation authority already combines net procurement with current advance procurement. The LRSO missile program and its nuclear warhead are separate acquisition efforts; the figures here do not claim a combined weapon-plus-warhead price.
