§ Mr. Hancock
To ask the Secretary of State for Defence what assessment his Department made of the(a) United States Navy exercise in January and June 1993 to test the accuracy of Tomahawk missiles and (b) the United States Defense Department publication Gulf War Air Power Survey findings in procuring Tomahawk missiles for Royal Navy submarines. 
§ Mr. Spellar
The US Department of Defence has assured us that no Tomahawk exercise firings were conducted during either January or June 1993. The US Government reported in both January and June 1993 that Tomahawk attack operations were conducted against targets in Iraq under the auspices of UN Security Council Resolution 688. Information received from the US DoD about those operations was used with much other information in reaching the decision to procure the Tomahawk weapon system for the Royal Navy.
There is no record of the US DoD publication entitled 'Gulf War Air Power Survey' being used in relation to procurement of Tomahawk.
