HMS Diomede (F16) was a Leander-class frigate of the Royal Navy (RN). She was built by Yarrow Shipbuilders in Glasgow. Diomede was launched on 15 April 1969 and commissioned on 2 April 1971. Her nickname was "Dimweed".

Royal Navy Service

In 1972, Diomede took part in the Second Cod War during the fishing dispute with Iceland, though thankfully Diomede's involvement was more quiet than her involvement in the subsequent Cod War. Also that year, Diomede joined the 3rd Frigate Squadron which was then based in the Far East.

In 1974, Diomede, took part in Task Group (TG) 317.2 which was a deployment that caused some controversy back in the UK when the TG, on its way to the Far East/Pacific, visited South Africa, which was at that time under apartheid rule, as well as performing military exercises with the South African armed forces. Diomede, along with the nuclear submarine Warspite, visited the port of Simonstown while the rest of the TG visited Cape Town. The TG, upon reaching the Far East performed a number of exercises and 'fly the flag' visits with Far East and Pacific countries. They did not visit South Africa on their return, and headed to Brazil for an exercise with the Brazilian Navy. Diomede returned to the UK in June 1975.

The following year, Diomede joined the Fishery Protection Squadron, and took part in the Third Cod War. During that 'war' in February, Diomede was rammed by the Icelandic gunboat Baldur, which performed a number of similar incidents to many ships during the Cod Wars. The following month, Diomede was involved in a similar incident with the same gunboat and just three days after that incident was again rammed by another gunboat, the Tyr, equally notorious to the RN during the Cod Wars. Astonishingly, later that month, Diomede was rammed once again by Baldur.

In 1977, Diomede took part in the Fleet Review, in honor of Queen Elizabeth II's Silver Jubilee as part of the 3rd Frigate Squadron.[1]

Also in the 1970s, Diomede was one of the seven Leanders used as the fictional "HMS Hero" for the BBC TV drama series Warship. All members of the crew were given Hero cap tallies for filming purposes.

Her modernisation that would have given her Exocet and Sea Wolf was cancelled due to John Nott's 1981 Defence Review and she was intended to be placed in the Standby Squadron but the decision was repealed due to the 1982 Falklands War. During that year, Diomede was deployed to the Persian Gulf on patrol.

Diomede returned to the South Atlantic in 1985 where she performed a number of patrols in the vicinity of the Falkland Islands as well as visiting the Island of South Georgia.

In 1986 she deployed again to the West Indies as the 'West Indies Guardship' accompanying HM Queen Elizabeth II aboard HMY Britannia. The Queen was so impressed by the way her ships company performed their duties, that she ordered 'splice the mainbrace'.

Pakistan Navy Service

In 1988, Diomede was decommissioned from the Royal Navy and subsequently sold to Pakistan where she was renamed PNS Shamsheer. PNS Shamsheer continued in service for many years until she was decommissioned by Pakistan Navy and scrapped.
