One estimate gives the Royal Navy roughly three cruisers backing the historical North Atlantic patrol line and raises that support pool to about five with the conversions. These ships do not have to defeat Scharnhorst and Gneisenau in a gun battle. Their task is to reach a sighting, transmit accurate positions, and remain fast enough to shadow the raiders until heavy forces arrive. The old Town hull's proven Atlantic seakeeping and the proposed bow and machinery changes make that information-and-contact role plausible.

More cruisers strengthen the North Atlantic patrol line
Adding rebuilt cruisers behind the armed merchant cruiser patrol line improves the Royal Navy's speed, radio reporting, and ability to maintain contact with German raiders.
