Three Royal Navy members die after helicopter crash in Devon early Wednesday

Three Royal Navy personnel have died after a Merlin Mk4 helicopter crashed in a Devon field during a night training exercise, the Ministry of Defence confirmed on Wednesday. The aircraft went down at around 3:45am near Sourton Down, close to Okehampton, on the edge of Dartmoor. The Standard reported the crash site as a field at Sourton Down, with several road closures immediately put in place.
General Sir Gwyn Jenkins, head of the Royal Navy, said the crash would be a "huge shock to all in our Naval community." Defence Secretary John Healey called the loss "devastating," saying the three personnel "served with excellence." No names have been released while families are informed, according to The Argus.
The crash happened in pre-dawn darkness at approximately 3:45am. Local resident Eddie Amhof described hearing the aircraft in trouble before impact. "I heard this horrendous noise... the engines were gone... then an almighty flash of red," he told ITV News. A loud explosion followed around five to six minutes later, likely caused by fuel igniting after the initial impact.
Devon and Cornwall Police received the first emergency calls at 3:45am. Fire crews, ambulances, and search-and-rescue teams reached the scene by 4:30am. The A386 and A30 Sourton Cross slip roads were closed immediately. Plymouth Live reported those closures are expected to remain in place for several days as investigators recover the wreckage.
The aircraft is believed to be a Merlin Mk4, operated by 846 Naval Air Squadron out of RNAS Yeovilton in Somerset, according to UK Defence Journal. The squadron regularly uses the Okehampton battle camp area for low-altitude exercises. The Merlin Mk4 can carry up to 24 troops, but only the crew was on board during this sortie. The Royal Navy operates around 25 of these airframes in total.
The crash site falls within the Commando Helicopter Force training zone — a stretch of Dartmoor used for high-stress qualification exercises. The Guardian reported that 846 Squadron may have been participating in a scheduled annual exercise. The Defence Accident Investigation Branch has taken charge of the inquiry.
This is not the first time a Merlin Mk4 has been involved in a fatal accident. In September 2024, a Merlin ditched in the English Channel during a night-flying exercise from HMS Queen Elizabeth. That crash killed Lieutenant Rhodri Leyshon and led to a temporary grounding of the entire fleet, according to Aerospace Global News.
Investigators and aerospace analysts are already drawing links between the two incidents. Witness accounts of the engines "cutting out" before Wednesday's crash suggest a possible dual-engine failure or gearbox fault. Safety experts warn it is too early to draw firm conclusions before the flight data recorder is recovered. A fleet-wide safety pause is widely expected while the investigation gets underway.
Prime Minister Sir Keir Starmer acknowledged the crash during Prime Minister's Questions at around noon, calling it a "deeply worrying time" for the families involved. He pledged to share more information as soon as it became available, according to The Guardian. The statement came roughly eight hours after the aircraft went down.
Defence Secretary John Healey and General Sir Gwyn Jenkins both issued formal statements by mid-afternoon. Local MPs, including Fred Thomas, adopted a cautious tone while waiting for further details from the MoD. The Independent noted that the government faces growing pressure to explain how a training exercise in a well-used zone led to the loss of an entire crew.
