How 26-knot freighters would change Atlantic convoys

What would change if Britain and the United States had many 26-knot freighters in World War II?

They could form fast convoys that challenged U-boats, but would need new turbine-powered escorts.

Large numbers of 26-knot freighters would make genuinely fast Atlantic convoys possible. Their speed would make it much harder for U-boats to gain an attacking position or keep contact. The change would not eliminate escort requirements because Britain and the United States would need turbine-powered escorts capable of crossing the ocean at the same pace, and aircraft would remain a threat. Slower Flower-class corvettes would still have work with ordinary convoys. Long-deployed Deutschland-class raiders might eventually struggle to match the freighters, although that remains a qualified possibility. Faster merchant hulls would reshape escort and interception problems without solving commerce protection by themselves.
