What to Know About US Weapons Stockpiles in the Iran Campaign

As US operations against Iran expand, attention is turning to the scale of weapons being deployed and how long stockpiles can sustain the pace of activity.

According to US Central Command, more than 20 weapons systems are being used across air, sea, land and missile defense forces, including advanced bombers, fighter jets and missile defense batteries such as Patriot and THAAD.

Missile interceptors are drawing particular focus. During last year’s 12-day conflict involving Iran, US officials cited in media reports said more than 150 THAAD interceptors were fired, accounting for roughly a quarter of available THAAD stocks at the time.

Lockheed Martin reports there are nine active THAAD batteries worldwide, each costing between $1 billion and $1.8 billion according to previous reporting.

Analysts note that interceptor production is complex and can take months due to manufacturing, integration and testing requirements.

Each interception can also cost hundreds of thousands to millions of dollars, depending on the system used.

While US officials maintain that stockpiles remain strong, the discussion highlights the financial and logistical demands of sustaining high-intensity operations over time, especially when advanced precision munitions and missile defense systems are involved.
