According to Thomas Harding in The Daily Telegraph, in order to get the Merlins out to Afghanistan by the end of the year, Kevlar armour has been omitted from the load compartment – thus producing a saving of £100,000.
The armour, similar to that fitted to a Snatch Land Rover, protects troops from small calibre weapons and fragmentation from RPGs, and has been a requirement in operational helicopters ever since June 2003. Then, a Chinook attempting to land a relief force to aid embattled troops in the Iraqi town of Majar al-Kabir, took heavy gunfire which injured seven, some seriously.
Writes Harding, the lack of armour will severely restrict the operational use of these helicopters. Possibly, they will be restricted to "safe" areas (if there are any) and for the transport of supplies rather than personnel. At over £30 million each for the six ex-Danish Merlins, this would make them the most expensive delivery trucks in the world.
