§ Dr. McDonald
asked the Secretary of State for Defence when he now expects the Challenger tank to come into service; how many have been ordered; and at what estimated unit cost.
§ Mr. Pattie
Challenger will begin to enter service in the mid-1980s. An order has been placed for sufficient Challenger tanks to equip four armoured regiments. The estimated unit cost is £1.5 million for a fully equipped tank at September 1980 prices.
