WEA. Joined Sep 83 picked up my hook Jan 87, PO April 88 then joined ship as section head July 88, buttons early 91. The regime at that time was to not draft you to sea until you were a PO.I have to dispute that Wrecks.
In my day (joined 1977) as a WE Artificer it was:
1 year at Fisgard
1 year at Collingwood
1 year on a ship
18 months at Collingwood
Out to the fleet as WEA3 (Leading Hand)
In the last 6 months of Collingwood we picked up our 'hooks' so the actual timescale from joining to LH was more like 4 years.
It was possible to reduce this by 4 months by only doing 2 terms at Fisgard instead of 3 as a 'accelerator'. (I did this).
I'm aware that things changed a bit when Fisgard closed but I'm not sure of the timescale.
Maybe that's what you're referring to...?
