What is the guidance method of the Tomahawk Guidance System?

The Tomahawk Guidance System predominantly employs inertial guidance as its primary method. Inertial guidance relies on onboard sensors to measure the missile's acceleration and orientation throughout its flight. This data is processed to calculate the missile's position and velocity, allowing it to navigate to its target with high precision while remaining completely self-sufficient in terms of inputs.

Inertial guidance is particularly advantageous in situations where other guidance methods, such as active radar or semi-active targeting, may be less effective due to countermeasures or environmental conditions. This allows the Tomahawk missile to maintain a predetermined flight path without relying on external signals, which contributes to its effectiveness in strike missions.

The Morton system, though it may also incorporate elements of other guidance methods, primarily relies on inertial guidance until it gets closer to its target where it may switch to terminal guidance techniques. The ability to navigate accurately without needing constant updates from external sources is what makes inertial guidance a solid choice for the Tomahawk missile.
