Further to my last, here's another comparison that makes you wonder WTF the Storm Shadow was ever ordered.
Combat range with 2 external tanks and 2 Storm Shadow: 972 km
Range of Storm Shadow: 250 km
Combined combat range Tornado/Storm Shadow without air-to-air refuelling: 1,222 km
Range: 2,500 km
Since entire coast of Libya is within 2,500 km of London, a sub sitting in the Thames could have done the same job as the Tornados and their refuelling tankers, more accurately and at a fraction of the cost.
