The British Steam Gunboats The Germans Could Not Outshoot In A Diesel War

In November 1941, while every other navy on Earth was building petrol or diesel coastal craft, the British Admiralty signed off on a steel-hulled, turbine-driven, 165-ton steam gunboat. Critics called it impossible. An engineering anachronism. Too slow, too large, too vulnerable. By June 1942 one of them was on the bottom of the Baie de la Seine, and the critics said they told the Admiralty so. They were wrong. This is the story of the British Steam Gun Boats — the seven-strong class that carried the First Steam Gun Boat Flotilla through Dieppe, the Channel battles of 1943, and the cross-Channel screen for D-Day. Commanded by Lieutenant Commander Peter Scott, the only son of the Antarctic explorer, the flotilla earned a Distinguished Service Cross and Bar in eight months of close-range night actions against German E-boats, armed trawlers, and minesweepers. HMS Grey Goose was the last to survive. In 1953, the Royal Navy lifted out her Metropolitan-Vickers steam turbines and replaced them with two Rolls-Royce RM60 marine gas turbines, making her the first warship of any kind to be powered entirely by gas turbines. The propulsion line that runs from Grey Goose runs through every Type 23, every Type 45, and every Type 26 frigate being built today. The boat the critics called impossible became the founding ship of the modern Royal Navy's propulsion system. ⚓ CHAPTERS 0:00 — A steam ship in a diesel war 2:00 — Why the Admiralty chose steam 4:30 — The boat that went to sea in 1941 6:30 — Baie de la Seine, June 1942 8:30 — Dieppe and the armouring decision 10:30 — Peter Scott and the First Steam Gun Boat Flotilla 12:30 — Le Havre, April 1943 14:00 — Cherbourg, July 1943 15:30 — The Straits of Dover, September 1943 17:00 — How the design compared 19:00 — Grey Goose and the gas turbine revolution 📚 SOURCES — London Gazette, 1 June 1943 (Distinguished Service Cross citation, Peter Scott) — London Gazette, 9 November 1943 (Bar to the DSC citation) — London Gazette, 28 September 1943 (Mention in Despatches) — Lay & Baker, paper to the Institution of Naval Architects on Steam Gun Boat design — Institute of Marine Engineering records on Grey Goose's 1953 gas turbine conversion — Imperial War Museum photographic archive and oral history collection — Admiralty action reports, ADM 199 and ADM 1 series, The National Archives, Kew 🚢 ABOUT THE CHANNEL British Warships is the only YouTube channel dedicated exclusively to Royal Navy vessels, weapons, and naval technology.
