For the delectation of 'WEBF' (& any interested others). The attached PDF is written by the chap responsible for setting up the CCA onboard MELBOURNE in the A4G/S2 era. I'll have to confirm this thought: the original CCA was the Venom radar being replaced by the GCA radar (also new in late 1960s I believe) at NAS Nowra. Anyhoo one does not get better first person stories than this one. Perhaps some detail is not correct such as 'I was told the A4G hook to ramp clearance was six feet' whereas the NATOPS minimum for A-4s was 6.5 feet. The detail about the first A-4B USN deck lander says it all - I had only heard his exclamation after his first and only cat shot.
