Unleashing the drones of war comes at a cost

A heavy reliance on Reapers avoids putting more US pilots at risk, but it has also led to Iranian air defenses shooting down dozens of the hunter-killer drones. The US military had lost nearly 30 Reaper drones as of May 2026, including some destroyed on the ground by Iranian counterstrikes, according to Air & Space Forces Magazine. The Air Force acknowledged such combat losses as reducing its Reaper fleet to about 135 drones.

The total US taxpayer bill for the destroyed Reapers comes to about $1 billion, according to Bloomberg. A typical Reaper may cost $30 million per aircraft, but the Air Force has said a Reaper equipped with a full sensor package can cost up to $50 million.

That number of Reapers lost in combat has almost certainly increased since May, as the United States and Iran have continued to trade airstrikes and drones despite so-called ceasefire periods and attempted negotiations. On July 8, as hostilities ramped up again recently with new Iranian strikes on commercial shipping triggering more US military airstrikes, Iran’s Islamic Revolutionary Guard Corps claimed to have shot down yet another Reaper drone.

The defense company General Atomics stopped manufacturing Reaper drones for the US military in 2025. But a General Atomics executive told Breaking Defense that the company is interested in pursuing the newest drone contract offering from the US military, and seemed to suggest it would provide a cheaper successor to the Reaper.

The Defense Innovation Unit notice called for drones capable of carrying many different sensor and weapons payloads up to 2,800 pounds and flying with a combat radius of at least 2,300 nautical miles—or 8,000 nautical miles on a one-way strike mission—while executing the same missions that the MQ-9A Reaper drone currently performs for the US military. It envisions delivery of “20 mission-ready aircraft” by 2031.

Whether the US military and companies can deliver on that vision of deploying cheaper yet capable strike drones remains to be seen. The Pentagon is asking for about $54 billion in its fiscal year 2027 budget to spend on drones and autonomous warfare technologies—an amount that rivals wartime Ukraine’s entire military budget.
