Which missile system uses an inertial guidance method?

The Tomahawk missile system utilizes an inertial guidance method as part of its guidance suite. Inertial guidance involves the use of accelerometers and gyroscopes to calculate the missile's position, orientation, and velocity throughout its flight. This method allows the missile to maintain a predetermined flight path and makes real-time adjustments based on its internal measurements, which is crucial for precision targeting.

Tomahawk missiles can also use GPS and terrain contour matching in conjunction with their inertial guidance system to enhance accuracy, especially as they approach the target area. However, the foundation of their guidance during the initial phase of flight is based on inertial navigation. This guidance capability is crucial for the Tomahawk's role in long-range, low-level cruise missile applications, enabling it to strike targets with a high degree of accuracy.
