An RAF officer examines the impact point of a 'Grand Slam' 22,000 lb bomb dropped on the U-boat factory at Farge, near Bremen, on 27 March 1945. The site at Farge – codenamed Valentin - was one of several hardened U-boat assembly facilities planned by the Germans in response to Allied bombing. Protected by massively thick roofs of reinforced concrete, they were invulnerable to all conventional bombing. Construction work was almost complete when 617 Squadron attacked on 27 March 1945. Of 12 'Grand Slams' dropped, two penetrated the 15 ft ferrous concrete roof and exploded, collapsing much of the structure.
