Look at Life was a popular British film series, short 8-10 minute documentaries shown in British theaters before a main attraction. Most were upbeat and interesting, if somewhat overly chipper.
But the short on the end of HMS Vanguard, in spite of the relentless optimism of the of the narrator, is poignant and sad.
HMS Vanguard was the last battleship completed anywhere. Laid down during World War II, competing shipbuilding needs meant she wasn’t completed until after the end of the war. A modified Lion class, she bore King George VI on a Royal Visit to South Africa. Other than that, she mostly spent her time in routine training, and serving as the flagship for various fleets and stations. And in 1960, she was decommissioned, and sent to the Clyde for scrapping.
