Abdiel was ordered from Thornycroft in June 1965. She was laid down at Thornycroft's Woolston shipyard on 23 May 1966[3] and launched 22 January 1967. She was commissioned on 17 October 1967.[1] Her pennant number was N21.[3]

Minelayer

Abdiel was designated by the Ministry of Defence as an "exercise minelayer" and her official role was to train Royal Navy personnel in minelaying operations using test/dummy naval mines, not to lay offensive mines operationally. She was fully capable of laying offensive mines during wartime.[4]

MCM support ship

Abdiel fulfilled an additional role as a support ship for mine countermeasure vessels. She served in this capacity with the Armilla Patrol from 1987 to 1988. During this deployment, the air conditioning units aboard ship proved insufficient for the climate and additional units had to be dispatched.[5]

Refits
  • 1977
  • 1981

Abdiel was paid off in 1988 and sold for scrapping. After her disposal, the Royal Navy had no dedicated minelaying vessel, although provisions were made for "suitably modified vessels" to undertake the work as required.[6]

Media

Abdiel appears in the Royal Navy instructional film 'Minelaying' (Admiralty catalogue no. A2788) produced in 1976. Classified as restricted at the time of its release, the film is now unrestricted and available on archive DVD collections and the Internet.
