About this forum

HMS Blyth is the second Royal Navy ship to bear the name. The previous Blyth was a Bangor-class minesweeper that was launched in 1940 and served in the Second World War.

The ship is crewed by 41 personnel, including ten mine warfare ratings and eight divers, along with officers, engineers and chefs. She has had 24 Commanding Officers over her 18 years of service.

Despite being a minesweeping vessel, HMS Blyth still packs a punch. She is fitted with a 30mm machine gun, two general purpose machine guns, three Mk44 miniguns and two .50 calibre heavy machine guns.

Commanding Officer

Lieutenant Commander Peter Ellison

Born and raised in Birmingham, Peter joined the Royal Navy in 2004 after completing a Master’s Degree at the University of Edinburgh. Fleet time was completed in HM Ships YORK, ST ALBANS and OCEAN before his first complement job as an Officer of the Watch (OOW) in HMS PORTLAND where he deployed to the North Atlantic for APT(N).


HMS Blyth's role

HMS Blyth’s job is to seek out, detect and destroy enemy mines. Mines are disposed of using the SeaFox unmanned underwater vehicle, or by highly trained Mine Clearance Divers.

Along with its fellow Sandown-class minehunters, HMS Blyth could be protecting trade routes in the Northern Gulf, taking part in NATO exercises alongside other nations, or patrolling the British coastline in search of unexploded ordnance from past conflicts.

By keeping international waters safe, HMS Blyth helps protect the UK’s economy and way of life.
