Would Britain choose helicopter cruisers or sloops?

Would the Royal Navy take the helicopter-cruiser route?

It did so after World War II, but this earlier scenario could begin with helicopter-carrying sloops based on a lengthened Black Swan design.

The Royal Navy adopted helicopter cruisers after World War II, but a prewar program could follow a smaller escort design. The original Black Swan provides a 1,250-ton starting point with six four-inch guns in three twin mounts. A longer hull could accommodate a helicopter, although the hangar must be tall enough for maintenance. A gun mounted above the hangar is one possible arrangement. Depth charges normally carried aft would conflict with the landing area, requiring a flight deck raised above that gear. The resulting layout could resemble a later helicopter frigate.
