He will oversee the continuing build of the Type 26 and Type 31 frigates, with them expecting to become operational towards the end of his tenure; the steel cut of the first Solid Support Ship; the seventh Astute-class submarine entering service and the continuing development of the Dreadnought-class of submarine.

A graduate of the Advanced Command and Staff Course at the Military College Shrivenham, General Gwyn went on to oversee global operations in PJHQ before serving in Afghanistan where he was awarded an OBE. Moving to No 10 Downing Street as the Military Assistant to the Prime Minister, he then worked in the Cabinet Office and led 3 Commando Brigade.

Rising to the position of General as Vice Chief of the Defence Staff in 2022 he was responsible for running the armed forces aspects of defence business, and in 2024 he was appointed Commandant General of the Royal Marines, a role which he will continue to hold.

Controversy hits Royal Navy

General Gywn takes on the role after his predecessor, Admiral Sir Ben Key, was asked to step back from his role after an alleged sexual relationship with a female officer under his command. Although no crime has been committed and the alleged affair is believed to be consensual, his conduct breached the force’s “service test” - banning relationships between commanders and subordinates. The Admiral, 59, has a wife and three children.

Adm Key, who was expected to retired this summer, is still under investigation. An MoD spokesperson previously said it would be “inappropriate to comment” while the investigation is taking place.

Lieutenant Commander Martyn Mayger, who was assigned to be Commanding Officer of the Portsmouth-based patrol vessel HMS Tyne in February, has also been removed from his post after allegations of “unacceptable sexual behaviour”.

The Times reports that Lt Cdr Mayger is being investigated by the Defence Serious Crime Command after a complaint regarding “unwanted” behaviour was raised in the past week.
