The US Navy has confirmed the loss of an MQ-4C Triton surveillance drone, one of the most expensive unmanned aircraft in the American military’s arsenal, during the ongoing conflict with Iran.

The MQ-4C Triton is valued at over $200 million per aircraft, approximately twice the price of two Lockheed Martin F-35 fighter jets, making it among the most expensive unmanned platforms in the US military inventory.

According to the United States Naval Safety Command, an MQ-4C Triton crashed on April 9, with no injury to personnel. According to the mishap summary, the high-altitude long-endurance (HALE) unmanned surveillance aircraft crashed in the Persian Gulf. However, it did not specify the exact location of the crash as it was withheld for operational security reasons.

The incident has been classified as a “Class A" mishap, a category used when damage exceeds $2.5 million or an aircraft is destroyed. The reconnaissance aircraft involved in the latest incident is worth around $240–250 million, according to US-based CBS News.
