The MQ-1 Predator was retired by the US Air Force in 2018. Eight years later, Iran just shot one down over the Persian Gulf. CENTCOM confirmed on 31 May that an American “MQ-1” drone was engaged and destroyed by Iranian air defences while operating over international waters. The US retaliated within hours, striking radar installations and drone command facilities at Goruk and on Qeshm Island. Fighter aircraft followed up by destroying Iranian air defences, a ground control station, and two one-way attack drones. The interesting question is not why Iran shot it down. The interesting question is why the MQ-1 is flying at all.

Back from the Boneyard?

The USAF officially retired the MQ-1B Predator in March 2018, replacing it with the larger, faster, more capable MQ-9 Reaper. As of September 2024, fifteen MQ-1Bs were still sitting in the Arizona boneyard at AMARG. CENTCOM declined to clarify whether the downed aircraft was an actual MQ-1B Predator pulled from storage or an MQ-1C Gray Eagle — the Army’s variant, which remains in active service and is deployed in the Middle East. The distinction matters. If the USAF is pulling mothballed Predators back into service, it suggests the MQ-9 fleet is under severe strain. And it is: Lt. Gen. David Tabor reported that the Air Force’s MQ-9 inventory has dwindled from 231 aircraft at the start of FY2025 to just 135 — a loss of nearly 100 Reapers in 18 months of operations against Iran. At roughly $30 million per MQ-9, the attrition is unsustainable. A mothballed MQ-1B, by contrast, costs almost nothing to reactivate. If the airframes are structurally sound, the logic writes itself.

The Retaliation

The US response was swift and kinetic. Strikes hit Iranian radar sites and drone command facilities, followed by fighter attacks on air defence systems on Qeshm Island — a strategic choke point overlooking the Strait of Hormuz. Two Iranian one-way attack drones assessed as threats to shipping were also destroyed. The exchange reflects the fragility of the April ceasefire. Both sides are still shooting. The only question is how long the pauses between the shooting last. Sources: The War Zone, Washington Times, Gulf Business, CENTCOM
