The US Navy has confirmed the crash of an MQ-4C Triton surveillance drone over the Persian Gulf, marking one of the costliest unmanned aircraft losses during the ongoing tensions with Iran.
Valued at over $200 million per unit, the MQ-4C Triton ranks among the most expensive drones in the US military inventory. Estimates place the cost of the lost aircraft between $240 million and $250 million.

Classified as ‘Class A’ mishap
Per News 18, according to the United States Naval Safety Command, the drone crashed on April 9, with no injuries reported. The exact location of the crash has not been disclosed due to operational security concerns.
The incident has been classified as a “Class A" mishap, a designation used when damage exceeds $2.5 million or when an aircraft is destroyed.
Emergency signal before disappearance
The drone reportedly vanished over the Strait of Hormuz after declaring an in-flight emergency. It was operating over the Persian Gulf when it began to descend unexpectedly.
Flight tracking data from Flightradar24 showed the aircraft transmitting a code 7700 general emergency signal. It then turned slightly toward Iran, entered a rapid descent, and disappeared from tracking systems shortly after.
What is the MQ-4C Triton?
Built by Northrop Grumman, the MQ-4C Triton is a high-altitude, long-endurance (HALE) unmanned aircraft designed for maritime surveillance.
It operates above 50,000 feet and can remain airborne for over 24 hours, covering a range of up to 7,400 nautical miles. The platform is equipped with a 360-degree multi-intelligence sensor suite, enabling continuous monitoring of large ocean areas.

The Triton plays a key role in coordinating with aircraft such as the P-8A Poseidon, acting as a high-altitude surveillance node while other systems operate below.
As of 2025, the US Navy had 20 Triton drones in service, with plans to expand the fleet further.
