HMS Broadsword (D31): The Destroyer That Accidentally Shelled Portsmouth

A Wartime Design, Built Too Late for War

HMS Broadsword was built by Yarrow Shipbuilders at Scotstoun, her keel laid on 20 July 1944, but by the time she was launched on 5 February 1946 the war she had been designed to fight was already over. She did not complete trials until 17 September 1948 and entered full operational service on 4 October that year, a Weapon-class destroyer displacing 1,980 tons standard and up to 2,850 tons at full load, armed with six 4-inch dual-purpose guns, six 40mm Bofors guns, ten 21-inch torpedo tubes and two Squid anti-submarine mortars, a heavily armed destroyer that entered service into a peacetime, Cold War fleet rather than the wartime one for which she had originally been conceived.

An Unscheduled Shot Over the City

HMS Broadsword joined the 6th Destroyer Flotilla of the Home Fleet on 29 December 1948, but her most memorable moment came not at sea but alongside her berth at Portsmouth, when on 25 March 1949 one of her 4-inch guns discharged accidentally, sending a live shell passing directly over the city, a genuinely alarming incident for anyone within earshot and a story that no doubt circulated around Portsmouth's pubs for years afterwards, even if the Admiralty's own account of the affair was considerably more measured than the version residents likely told their friends.

Tragedy at Sea

The following year brought a genuinely sombre incident: on 14 January 1951, a fire broke out aboard HMS Broadsword, and one rating was killed by smoke inhalation, a stark reminder that even routine peacetime service aboard a warship carried real danger, and that the fires, machinery and confined spaces of a destroyer could prove just as lethal in port or on exercise as any wartime action.

A New Role as a Radar Picket

HMS Broadsword entered reserve at Chatham in April 1953 before transferring to Portsmouth in April 1955, and in 1957 was converted at Rosyth to a radar picket configuration, recommissioning in October 1958 with her torpedo tubes removed to make way for the additional radar and command facilities the role demanded, reflecting the Cold War's growing emphasis on early warning and air defence coordination over traditional torpedo attack. She was allocated to the 7th Destroyer Squadron and served in Home and Mediterranean waters until paying off in 1963.

Target Practice, and the Scrapyard

HMS Broadsword was towed to Rosyth on 25 April 1968 for use in target trials, her hull put to one final use testing the effects of weapons before she was scrapped at Inverkeithing, arriving there on 8 October 1968, closing out the career of a ship whose most enduring legacy was probably not her decade and a half of solid Cold War service, but the memorable afternoon in 1949 when Portsmouth briefly found itself, quite unintentionally, within range of one of its own destroyers.
