Cost & funding breakdown
Patriot modifications budget
$757.8M
FY2026 · PB2026 · Nominal USD; source budget basis
Army Missile Procurement line 29. Modernization program funding, not a new-battery price; FY2026 is the request.
U.S. Army ↗Shared Patriot / PAC-3 / LTAMDS annual RDT&E
$317.9M / yr
FY2025 request · Nominal USD; source budget basis
Broader weapon-system book category. Not attributable solely to Patriot, PAC-3 MSE, or LTAMDS; do not add this to their development figures.
DoD Comptroller ↗Specify what a battery package contains
The Romanian notification enumerates the equipment rather than a universal battery configuration. Launcher count, interceptor type, radar, training and support must be specified before comparing package prices.
A complete Patriot package contains several products
The German award includes radar, launchers, control equipment, spares and support. PAC-3 MSE interceptor and LTAMDS radar costs have separate profiles and cannot be assumed to be included in this award.

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 · 3 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.

Coverage & open research
- Current U.S. inventory and complete annual operating-and-support costs require additional public evidence.
- Buyer records are selected examples, not a complete global order book.
- Unit cost (per unit)Reported$1.10BEstimate / observation: 2022-12-16 · Then-year $ · 1 unit
Unit = one newly produced Patriot battery (US cost), CSIS estimate (Cancian/Karako): ~$1.1B total = ~$400M for the system (radar, launchers, control/support equipment) + ~$690M for the missiles (initial load plus two reloads, mix of PAC-2/PAC-3). CSIS also cites ~$1.27B per new US Patriot battalion excluding missiles. Same figures repeated in CRS IF12297 (Jan 2023). Official figures not published.
Source - Contract unit priceEstimated$425MEstimate / observation: 2025-12-23 · 4 units · Spain
Unit = one Patriot air and missile defense system (fire unit) for Spain. Raytheon contract worth $1.7B to deliver four Patriot systems (Reuters). Derived: 1,700,000,000 / 4 = $425M per system; contract scope may include training, support and spares; interceptor content not stated.
