The United Kingdom’s Ministry of Defence (MOD) is preparing for the construction of the Royal Navy’s two new Future Aircraft Carriers (CVFs), slated to enter service in 2012 and 2015, respectively. The CVFs could be the largest warships ever built in the United Kingdom. At the request of the MOD, the RAND Corporation looked at the risks of current contractor plans and estimated the cost implications of using alternative manufacturing options in the coming years.
