§ Mr. Jenkin
To ask the Secretary of State for Defence how many Sea Harriers have been equipped with JTIDS; and at what cost. 
§ Dr. Moonie
JTIDS has been fitted to three Sea Harrier aircraft. Two of these are development aircraft operated by BAE Systems. The costs are currently the subject of negotiation with contractors and I am therefore withholding this information in accordance with Exemption 13 of the Code of Practice on Access to Government Information.
