The United States Navy has confirmed the loss of one of its most advanced and expensive drones, an MQ-4C Triton, which crashed over the Persian Gulf on April 9. The Navy’s Safety Command disclosed the incident in a report released on Tuesday but withheld the exact crash location for operational security reasons. According to flight tracking data from FlightRadar24, the drone took off from the Sigonella naval base in Italy and went missing while flying over the Persian Gulf.

Data showed that the drone suddenly dropped from 50,000 feet to 9,000 feet before losing all communication. It first transmitted a '7400' signal, indicating loss of contact with ground control, and about 70 minutes later sent a '7700' emergency signal before disappearing from radar at 9,250 feet. The Navy has not yet provided any explanation for the cause of the crash.

The report, citing CNN, marks a rare public acknowledgment of a high-value drone loss by the US military in the Middle East.
