Enterprise's crew left the ship after her last homecoming in 2012, and they were then dispersed to new drafts across the fleet. Other carriers mainly, They did not march down one gangplank from the Big E straight onto the Ford, although inevitably some will have ended up on the Ford.Is it not connected to the decommissioning of the Enterprise?
It was decommissioned on the 3rd of February 2017, and in six month time they commissioned the Ford.
I presume that the Enterprise crew could lose lot of experience if they don't have another deployment.
By the same token the crews of the British carriers were kept busy in between Ark Royal paying off in 2010 and Illustrious paying off in 2014, mostly by being posted aboard USN Carriers and the French CdG, so that their skill were maintained in the interregnum.
