OK, clearly some here not familiar with JFH.
The RN couldn't provide the necessary number of crews that had been agreed (50/50 split) to man the OCU and the sqns. Hence the collapse into a "NSW". It isn't contentious, just straight fact. The reasons why may be contentious and it would be interesting to hear from those involved why it was the case (not random idiots who have no idea what they are talking about).
The perception, which may be totally incorrect, is that the RN marginalised this aspect of the FAA while they were desperately trying to defend the surface fleet. Essentially they took their eye off the ball which they now realise was a huge mistake and are trying to scramble back. Unfortunately their reputation in terms of joint orgs and fixed wing flying has taken a pretty bad bashing.
