This is one of the best-known tools of the US Navy, and not without good reason. The range of a Tomahawk cruise missile is incredible - they can land with precision on a target over a thousand nautical miles away.
That means they can be fired by submarines and ships at sea, and reach targets which lie far inland from them. GPS systems and cameras help operators to ensure they stay on the right path, and make it all the way to their intended destination.
