TOMAHAWK CRUISE MISSILE
The Tomahawk, shown in figure 1-12, is a long-
range, subsonic cruise missile. The Tomahawk can
be a conventionally armed antiship version for
antisurface warfare, a conventionally armed land-
attack version, and a nuclear armed land-attack
version.
The Tomahawk is an all-weather submarine-
launched or surface combatant-launched antiship
or land-attack cruise missile. After launch, a solid-
propellant rocket booster propels the missile until
a small turbofan engine takes over for the cruise
portion of the flight. The land-attack version of
Tomahawk has an inertial and terrain-matching
guidance system.
The antiship version has a modified Harpoon
cruise missile guidance system. This system
permits Tomahawk to be fired and to fly at low
altitude in the general direction of an enemy
warship to avoid radar detection. At a
programmed distance, the missile begins an active
radar search to seek, acquire, and hit the target
ship.
