Long range, subsonic cruise missile used for land attack warfare.
An all-weather submarine or ship-launched land-attack cruise missile.
After launch, a solid propellant propels the missile until a small turbofan engine takes over for the cruise portion of flight.
Highly survivable weapon.
Radar detection is difficult because of the missile's small cross-section, low altitude flight.
Infrared detection is difficult because the turbofan engine emits little heat.
Systems include Global Positioning System (GPS) receiver; an upgrade of the Digital Scene Matching Area Correlation (DSMAC) system; Time of Arrival (TOA) control, and improved 402 turbo engines.
The land attack version of Tomahawk has inertial and terrain contour matching (TERCOM) guidance. TERCOM uses a stored map reference to compare with the actual terrain to determine the missile's position. If necessary, a course correction is then made to place the missile on course to the target.
