Problems in Prince of Wales turrets during her first action against Bismarck, according to her Gunnery Aspects Report: "A" Turret: No. 1 gun failed after the 1st salvo, from a previously known defect. No. 2 and No. 4 guns suffered from intermittent safety interlock problems. "A" turret suffered from water entering the lower portion of the turret/barbette structure, but there is no indication that this caused any problems other than discomfort for the crew. At Salvo 18, when Prince of Wales turned away, three of 'A' turret's guns were in operation. "B" Turret: No problems reported. At Salvo 18, when Prince of Wales turned away, both of 'B' turrets guns were in operation. "Y" Turret No.2 gun had loading problems and missed salvo 14 onwards.
