Could the Allies have used a captured Bismarck?

What would happen if the Royal Navy captured Bismarck and brought her into an Allied port?

She would most likely be studied and stripped rather than quickly recommissioned; even an American rebuild or Free French carrier conversion would be costly and late.

Germany would try to sink a captured Bismarck while the crippled ship was being towed to an Allied port. Even if she arrived, unfamiliar machinery, missing plans and spares, and extensive battle damage would make a return to service difficult. Nevada provides an unfavourable repair comparison because the Americans already possessed her drawings, parts, and materials. An American rebuild of Bismarck is estimated to take until late 1944 or early 1945, with a substantial risk that wartime priorities would cause the project to be set aside. Fleet's alternative is a Free French carrier conversion, which would replace the machinery and remove the need to adapt the German gun batteries. Intelligence exploitation is judged the more realistic outcome, with surviving guns, radar, and fire-control equipment examined before the ship was stripped. The remaining steel could be scrapped, or the hulk could conceivably become a Mulberry breakwater for the Normandy landings.
