Among the problems which the paper said it had identified were:
:: An inability by the “stealth” F-35 to transmit data to British ships and older aircraft without revealing its position;
:: The aircraft’s software system is vulnerable to cyber attack and cannot be tested independently by the UK;
:: Weak broadband on the Royal Navy’s principal aircraft carrier is hampering the jet’s abilities;
:: The department responsible for the computer networks essential to the aircraft’s operation needs to find savings of £400 million this year.
The Ministry of Defence (MoD) said that all the issues raised had been reported in the past and were under “active management” by the Joint Strike Fighter joint programme office and the MoD.
