A proposed game refit would rapidly convert Sweden's coast-defence ships to a preferred type, producing twelve of them. The recommendation explicitly acknowledges that the conversion would be physically impossible in reality. Its attraction in the game is enough firepower to make an attack by Germany's navy more difficult. A later check finds that Sweden already has a 1936 destroyer hull and a reasonably good starting destroyer design.

The game permits a rapid Swedish coast-defence conversion that the players explicitly regard as physically impossible.
