She was
commissioned on 16 May 1973 into the Royal Navy as HMS
Mermaid with the
pennant number F76 and after working up was dispatched to the
Far East where she was based at
Singapore. Her light armament and minimal sensor fittings made her unsuitable for a role in the European environment but could provide a useful presence in the
Far East, undertaking what is now known as 'defence diplomacy' roles. She stood in for (the guardship for
Hong Kong) at times and stood by at the end of the
Vietnam War in case
British nationals had to be evacuated from
Saigon. Returning to home waters in 1976,
Mermaid was deployed to protect British
trawlers off
Iceland during the
Third Cod War. After a previous ramming incident with the Icelandic gunboat on 12 March, she suffered heavy collision damage on 6 May during aggressive manoeuvring with the patrol boat . During a
NATO exercise on 20 September 1976, she was involved in a collision with the
minesweeper that resulted in the
Fittletons sinking and the deaths of 12 personnel, mainly RNR members.
Mermaid's last task before being
paid off was to conduct trials on a
moving target indication system that enabled
radar to pick out targets moving against the clutter generated by the surface of the sea. Her Royal Navy career of only five years ended in early 1977. She was the last British warship to operate twin 4-inch guns, which had been in service for well over thirty years. == Royal Malaysian Navy service ==
