Would leaving Béarn for Germany be a useful way to burden German carrier development?
Short answerNo. France and the Allies could use Béarn more practically as an escort carrier for anti-submarine work in the mid-Atlantic.
NotesThe answer rejects sacrificing an imperfect carrier merely because it cannot match a modern fleet unit. Béarn's lower performance still suits convoy escort and anti-submarine coverage. Those duties value aircraft presence and endurance more than high fleet speed. In the mid-Atlantic gap, even limited aviation capacity could address a real operational shortage.
