Iran has destroyed more than 24 MQ-9 Reaper drones operated by U.S. forces since the beginning of the war. This represents a significant loss worth nearly $1 billion, accounting for 20% of the Pentagon’s unmanned systems inventory before the war – systems that are difficult to replace. This was reported by Bloomberg, citing a source involved in the matter. Many of the attack drones were shot down during flight by Iranian fire, but some were destroyed on the ground in missile attacks or in accidents.
