Gas turbines give Coastal Forces a forty-knot test bed

Small attack craft turn the experimental turbine program into an operational advantage before the machinery reaches major warships.

Notes

The scenario follows the Royal Navy's historical practice of testing marine gas turbines in motor torpedo boats, with that path moved into the mid-1930s. Two early 15,000-shaft-horsepower turbines could give a British craft roughly 30,000 shaft horsepower and a speed near forty-five knots. The result combines the profile and armament of a British Dog Boat with speed comparable to a German Schnellboot. The small hull absorbs development risk while demonstrating whether the compact machinery, gearing, and high power-to-weight ratio work at sea.
