The author suggests that NATO missiles should be based on high-speed craft capable of operating in coastal shallow waters rather than on shore. For this purpose he proposes that use be made of planing-hull craft equipped with a Wave-Forming Keel; this concept is briefly described. Basically the wave-forming keel is a free-flooding and free-breathing structure of triangular section mounted beneath the main hull. The "keel" is made up of a number of units spaced along the length of the vessel, each being of lesser depth at the forward end than aft, and penetrating a short distance into the base of the next ahead. This arrangement overcomes a defect of the conventional stepped hull planing craft which loses the air supply to the planing surface in rough water. With the wave-forming keel air is drawn in from aft by the venturi action of the keel sections and discharged to the hull surface at the base of each section. In addition the triangular cross-section of the keel units enables them to withstand high slamming loads. It is suggested that with this arrangement speeds of 60 to 100 knots can be obtained with about one shaft horsepower per 25 lb of ship weight.
