Nato's firepower: The cruise missile
Up to 80 cruise missiles were fired at Sudan and Afghanistan
The Tomahawk cruise missile's apparent ability to strike at enemy targets with pinpoint accuracy was well documented in the 1991 Persian Gulf War.
Current variants of the missile are 18ft long and weigh 2,650lbs.
They can carry conventional 1,000lb bombs or nuclear weapons, or clusters of smaller 'bomblets'.
They were used in the US air strikes that helped end conflict in Bosnia in 1995.
The Clinton administration also launched about two dozen missiles against Iraq in 1993 to retaliate for an assassination attempt against President Bush.
Development of the cruise missile, as we know it, has been underway since World War II.
The German V1 bomb, which caused massive destruction in London, was really the precursor for the highly sophisticated weapons inuse today.
Many modern cruise missiles, however, have a far greater range than the V1's 200 miles.
And whereas the V-1, which flew a predictable course at a fixed altitude, was ultimately defeated, modern cruise missiles pose far greater challenges to air defences.
They can be launched from concealed land locations, from submarines or warships, or just as easily from merchant ships, fishing boats or even commercial airliners.
In flight they can follow erratic courses, actively evade air defences and attack their targets from unpredictable directions.
Their bodies are basically un-manned aeroplanes which can be programmed to reach a target, or can be guided, in-flight, from base.
And they cost up to one tenth of the total required to develop, purchase and deploy ballistic missiles - such as Iraq's infamous Scuds.
