Mk 54 Lightweight Torpedo
Mod 1 upgrade-kit estimates are separated from complete Mod 0 torpedoes and proposed export packages.
Mod 1 hardware kit / unit
$1.152M
FY2025 request · Nominal USD · source budget basis
P-5 F5110 MK-54 MOD 1 kit line. Upgrade hardware, not a complete torpedo. Values shown in thousands in the source are preserved at that precision.
U.S. Navy · government budget document mirror ↗U.S. inventory
Not verified
A current U.S. inventory was not established. Annual procurement, cumulative deliveries and production capacity are not a stockpile count.
Requested Mod 1 hardware kits
51
FY2025 request · U.S. only; stated source scope
Kit quantity only; not complete new torpedoes or current inventory.
U.S. Navy · government budget document mirror ↗R&D program total
Not verified
A lifetime program R&D total was not established. Development contracts and shared program budgets are not substituted for that total.
Cost & funding breakdown
Lightweight torpedo annual RDT&E reference
$102.159M / yr
FY2027 total request · PB2027 · Nominal USD; source budget basis
R-1 PE0604610N Lightweight Torpedo Development. Annual appropriation, not lifetime development. FY2026 includes listed reconciliation spend-plan funds; FY2027 is requested funding. Shared scope; cannot be attributed solely to this product.
Department of Defense Comptroller ↗Kit, torpedo and export package are different units
The headline is a Mod 1 modification kit. India’s proposed Mod 0 package includes complete torpedoes and associated equipment. Dividing its full value by 53 would not yield a directly comparable kit or bare-torpedo price.
Operations & sustainment
Annual operations & support
Not verified
A complete, system-specific annual operating and support cost was not established. Procurement, replacement rounds and contract support are different measures.
Cost over time · 6 observations
Each row retains its original scope and dollar basis. Changing quantities, service life and inflation can change the estimate without changing the price of building one unit.
