Is making a public fuss really the best way of doing things? Is there a magic pot of money for recruiting extra people? The RN was meant to get an uplift of 3000 people last year.....
If not - then they would be better of trying to manage what we do have.
However:
....on a ship there is a definite minimum crew and if you can't meet that it goes nowhere - like the T45's last year
Apart from HM Ships Dauntless, Defender, Dragon, and Duncan which all deployed in 2015. Interestingly perhaps, the other two (Daring and Diamond) have both recently deployed on operations.
