 Many of the program's financial and technical complications result from the Marine version of the JSF, capable of vertical take-offs and landings.On 11 March 2010, United States Senate Committee on Armed Services investigated the progress of the JSF program in a meeting with Pentagon officials, emphasizing cost due to the risk of a Nunn-McCurdy process.According to the Government Accountability Office, F-35A cost has risen from $50m in 2002, via $69m in 2007 to $74m in 2010, all measured in 2002 dollars.
