Summary
In 1995 the Ministry of Defence (MoD) ordered 15 Chinook Mk2a helicopters from Boeing, of which six were retained as Mk2a with the other eight modified as Mk3 to meet a longstanding requirement for dedicated helicopters for special operations. Those eight Chinook Mk3 helicopters cost some £259 million and the Department took delivery of them in December 2001. Although Boeing met its contractual obligations, the avionics software fell short of UK military airworthiness standards and the helicopters have not flown in operations.
This Report from the National Audit Office, 'Chinook Mk3 Helicopters' (HC 512), examines whether the MoD has taken appropriate steps to make the eight Chinook Mk3s operational.
