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.

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.
