General Dynamics was awarded the (£1.7 billion) Prime Contractor and Systems Integration contract for the BOWMAN secure, digital voice and data communications system in September 2001, while Walmsley was still in charge of MOD procurement. On retirement in April 2003 Warmsley was offered a lucrative directorship of General Dynamics. A government watchdog committee advised Walmsley not to take up the post for one year after he had retired from the MOD, to avoid the appearance of a 'reward' being given by General Dynamics to Walmsley. Walmsley publicly joined General Dynamics in April 2004. He had by then, already become a non-executive director on the board of British Energy.
