The Submarine Torpedo Boat
Its Characteristics And Modern Development

CHAPTER IX TACTICAL EVOLUTIONS OF THE SUBMARINE Submarine warfare, like all other naval fighting, re- solves itself into defensive and offensive operations. The defensive operations of the submarine consist chiefly of the protection of harbors and the prevention of an enemy’s fleet from bombarding seaports and from landing an invading army anywhere along the coast. The effectiveness of the weapon in this respect is a well demonstrated fact, but to sucessfully carry out a pro- gram of protection by its means, it is evident that with the extensive coast lines this country has, we must provide a considerable number of coast defense submarines for the purpose. These boats should be distributed in groups of six or eight at various bases along the coast and more particularly at points where it is considered essential for strategic reasons to concentrate defense. These groups accompanied by mobile tenders should be located particularly at the strategic points as follows: On the East Coast at Eastport, Me., Portsmouth, N.H., Provincetown, Mass., Woods Hole, Mass., Newport, R.I., New York, N.Y., Delaware Breakwater, Norfolk, Va., Charleston, S.C., Key West, Fla., Pensacola, Fla., Gal- veston, Texas, and at the eastern entrance to the Panama Canal. On the West Coast at some port in Alaska, Port Townsend, Wash., Columbia River, Ore., San Francisco, Cal. (2 groups), Santa Barbara, Cal., San Pedro, Cal., 153
