The fleet was spotted by the Germans and attacked by aircraft from the KG 26 and KG 30 bomber wings. Hood was hit by a 250 kg (550 lb) bomb from a Junkers Ju 88 bomber that damaged her port torpedo bulge and her condensers. By early 1940, Hood's machinery was in dire shape and limited her best speed to 26.5 knots (49.1 km/h; 30.5 mph); she was refitted between 4 April and 12 June.[60]
