Bismarck went to sea in a tiny group, while its cruiser companion later separated for its own protection. Without carrier support, the battleship lacked long-range reconnaissance and fighters able to break up incoming air attacks. The deeper problem was structural: Plan Z demanded modernization and expansion of existing yards, construction of new yards, and much greater maritime infrastructure before its paper fleet could exist. Placing the construction program under Göring compounded the difficulty, while earlier direction by Speer appears only as a possible improvement. Germany had not built a balanced foundation, and the destroyer losses at Narvik left too few suitable escorts for its surviving heavy ships.
