The 20ft Tomahawk missile carries a 1,000lb high-explosive warhead with the power to destroy a building.
It has a range of more than 1,550 miles, travels at more than 550mph and has a GPS guidance system allowing it to switch targets mid-flight.
Tomahawk land-attack cruise missiles were last fired by the Navy in 2011 against Gaddafi’s military facilities in Libya.
And they were used by the Navy in Iraq in 2003 and Afghanistan in 2001.
