§ Mr. Hancock
To ask the Secretary of State for Defence what modifications will be required to the dimensions of the Joint Strike Fighter to permit it to be operated from Invincible class aircraft carriers. 
§ Mr. Spellar
The operational requirements document for the Joint Strike Fighter incorporates Royal Navy requirements, which are very similar to those of the US Marines. Royal Navy requirements include the ability for the Short-Take Off, Vertical Landing variant to operate from the invincible class aircraft carriers without modification to the aircraft.
