The U.S. Navy has confirmed that an MQ-4C Triton surveillance drone crashed on April 9, 2026, ending a flight that disappeared from online tracking sites while it was over the Persian Gulf. The service described the loss as a mishap and said no personnel were injured.
The Navy said the incident was a Class A mishap, its most serious category, and budget documents last put the unit price of an MQ-4C at just over $238 million. As of 2025, the Navy had 20 of the drones in service and planned to buy seven more.
The aircraft had been heading back to Naval Air Station Sigonella in Italy after a surveillance mission over the Persian Gulf and Strait of Hormuz, and its transponder was broadcasting code 7700 during the emergency. There were also reports that the Triton had initially squawked 7400, though the last public tracking placed it in international airspace over the Persian Gulf and pointing toward Iran.
The drone had dropped suddenly from around 50,000 feet to below 10,000 feet before the tracking feed ended, but there is no evidence it went down in Iran. The circumstances that led to the loss remain unknown, and there are no indications that hostile fire caused the crash.
The missing aircraft matters because the Triton is built to collect surveillance data from long range, and the Navy and Northrop Grumman have been upgrading its signals intelligence suite in recent years. If wreckage is recovered, those systems could represent an intelligence loss as much as a hardware one, but for now the crash site has been withheld for operational security and the key question is where the drone came down.
