U.S. lost 25% of Reaper drones in Iran war, Washington Post reports

The United States military has lost at least 45 MQ-9 Reaper drones during its five-month war against Iran, representing roughly 25% of its 185-drone fleet. With each drone costing up to $50 million, the losses total up to $1.3 billion. The depletion of these vulnerable, slow-flying aircraft has intensified concerns over dwindling U.S. stockpiles, prompting Deputy Defense Secretary Steve Feinberg to demand accelerated production plans from industry leaders. In response to these vulnerabilities, the Pentagon is shifting its focus toward developing cheaper drone swarms.

Reaper drone combat losses

• ▪The United States military has lost at least 45 MQ-9 Reaper drones, representing approximately 25% of its stockpile, during the ongoing war against Iran as of August 13, 2026.
• ▪Air Force Lieutenant General David Tabor informed the Senate in May 2026 that the number of remaining United States military drones had fallen to roughly 135.
• ▪While some MQ-9 Reaper drones were shot down during the war against Iran, others crashed after operators lost connection to the aircraft, according to a United States official.
• ▪United States Marine Corps spokesperson Lieutenant Colonel Joshua Benson stated that none of the Marine Corps' 20 MQ-9 Reaper drones have been lost in the war against Iran.
• ▪At the start of the war against Iran, the United States military fleet had approximately 185 MQ-9 Reaper drones, including 165 in the Air Force and 20 in the Marine Corps.

Drone production costs

• ▪Each MQ-9 Reaper drone costs between $30 million and $50 million to produce, depending on its sensor payload, bringing the total cost of the lost drones to up to $1.3 billion.
• ▪The slow, low-flying design of the MQ-9 Reaper drones makes them vulnerable targets in the conflict against Iran, according to reports on August 13, 2026.

U.S. weapons stockpile depletion

• ▪The Trump administration's war against Iran has reached an estimated total cost of more than $100 billion over more than five months of military operations.
• ▪A Center for Strategic and International Studies report from May 2026 estimated that restoring the United States missile stockpile to pre-war levels will take until at least 2030.

Pentagon production acceleration efforts

• ▪Pentagon spokesman Sean Parnell stated that the Department of Defense is actively focusing on boosting munitions acquisitions to meet warfighter needs, claiming the effort predated the war with Iran.
• ▪Deputy Defense Secretary Steve Feinberg directed defense industry leaders in August 2026 to submit plans within three weeks to accelerate delivery schedules and increase production of critical military capabilities.

Cheap drone swarm development

• ▪During military exercises earlier in 2026, Ukrainian operators easily defeated United States forces, highlighting a learning curve as the Pentagon shifts to cheap drone swarms.
• ▪The Pentagon is shifting its development focus toward cheap drone swarms to replace older, more expensive platforms like the MQ-9 Reaper drone.
