Development and History
Mark IX
It included an improved version of the heater and engine from the VI*** H torpedo, with B 2 design.
It was 12 feet, 10 inches in overall length, weighted 996 pounds and carried a 170 pound Amatol warhead. It could make 29 knots to 2,000 yards. It had -45.5 pounds buoyancy at total weight, and +16 pounds empty: 39 pounds air, 18.9 pounds water (282 fluid ounces), 2.1 pounds fuel (42 fluid ounces). The A.V. could hold 5 cubic feet at 1,500 psi action pressure.[3]
In 1918, "B" warheads with 250 pounds rather than 170 pounds of explosive were being manufactured.[4]
