Jackies from the U. S. SS. Utah recovering a
spent torpedo after target practice.
A torpedo
is like a small, independent submarine. It is 21
feet long, 21 inches in diameter, and is divided
into six compartments. The first or front com-
partment contains damp gun cotton and detona-
tor which explodes the torpedo when it comes
into contact with anything solid, as a ship's
side. Second, compressed air tank containing
1,350 pounds of air to drive the propellers.
Third, balance compartment from which project
horizontal planes. Fourth, engine compartment
containing turbine type motor driven by com-
pressed air. Fifth, buoyancy compartment hold-
ing enough air to keep torpedo from sinking
and make it easily propelled. Sixth, gyroscope
compartment to insure its continuance on the
course aimed. The torpedo also has horizontal
and perpendicular rudders which may be set at
any angle, and strong twin propellers.
