How Argentine navy came toÂ HMS Sheffield's aidÂ a few years before destroying battleship in Falklands War
The sinking of the HMS Sheffield during the Falklands War is a tragedy which will never be forgotten in the city which gave the battleship its name.
Twenty people on board the destroyer died and many more were injured when it was hit by an Argentine missile on May 4, 1982, making it one of the darkest days in Britain's modern military history.
As the city welcomes the announcement a fourth HMS Sheffield will be built, a trawl through the archives reveals how quickly international relations can change.
It is hard to believe that just seven years before the second HMS Sheffield's sinking, when the doomed ship was commissioned in 1975, its builders had been hailing aÂ collaboration with the very nation againstÂ which Britain would soon be at war.
A commemorative programme produced by the shipbuilders Vickers and Barrow describes, in a feature titled '˜A new Sheffield '“Â a new age',Â how the Argentine Navy helped ensureÂ the British ship was completed on time.
'An example of the builders' ingenuity followed a tragic accident which occurred not long before the planned launch day,' it reads.
'Two men lost their lives in an explosion and part of the ship was extensively damaged.
'Vickers had already won an order for two Type 42 Destroyers for the Argentine Navy and the first of these was already being built in the yard.
'With the ready agreement of the Argentine Navy, Vickers '“Â rather than delay the launch '“Â repaired the Royal Nacy vessel by direct replacement with the equivalent section from the Argentine ship.
'Valuable time was thus saved by a '˜round-the-clock' effort, reminiscent of the 1939-45 war years.'
The D80 destroyer was eventually launched by the Queen as planned on June 10, 1971.
The commemorative programme states: 'HMS Sheffield of 1975 is proud of the tradition behind her name. The Senior Service has, times without number, written glorious pages in the history of Great Britain, and the first Sheffield played her part to the full.
'The story of the new Sheffield has only just begun.'
