Lütjens had requested that Raeder delay Rheinübung long enough either for Scharnhorst to complete repairs to her engines and be made combat worthy and to rendezvous at sea with Bismarck and Prinz Eugen or for Bismarck's sister ship Tirpitz to accompany them. Raeder had refused, as Scharnhorst would not be ready until early July. The crew of the newly completed Tirpitz was not yet fully trained, and over Lütjens's protests Raeder ordered Rheinübung to go ahead.
