It however would have faced a greater submarine threat, going by that. And that would have made a proper buildup harder.This was a question of production priorities. In 1942 LSTs were the number 1 production goal. When it became apparent that there would be no invasion in 1942 and probably not in 1943 LST production was dropped to 11. The new number 1 were destroyer escorts and that together with the allocation of B-24 planes to anti submarine duty won the war, or at least avoided a defeat. Now LST production could have been higher than 11th and this would have allowed a cross channel invasion in 1943, IT would in my opinion have been a risky move but it could have worked.
