Carrier days 'on the line'?
Posted on: 11/10/2016 11:35:52 PM
A reason HMAS Melbourne didn't go to Vietnam in 1966 or 67 was she could only spend 10 days 'on the line' compared to 30 or so of a USN carrier, the Sydney was the same in Korea.

So we know a Majestic class spends 10 days on the line, a USN carrier 31 days but does anyone know how long the RN carriers of the 60s HMS Eagle, Ark Royal, Victorious and Hermes could spend on the line conducting war operations?

I'm trying to find a source for the 16 and 12 day figures but the percentages are OK, so bear with me.

I recall reading that a Nimitz class was designed sustain 16 days of continuous strike operations compared to 12 days for the Enterprise by having 20% more aviation fuel and stores due to much less machinery. The Enterprise had 50% more aviation fuel and stores than the Kitty Hawk class, Wiki says the Nimitz class had 90% more fuel and 50% more ordnance than the KH/Forrestal, so circular logic of the numbers are more or less right as far as I can tell. With this amount of aviation fuel and stores and the USN fleet train the USN carriers could stay on Yankee station for ~30 days, meaning 4 carriers with ~30 days on the line and 10 days off line back to Subic could keep 3 carriers on Yankee Station indefinitely.

The proposition was for Melbourne to be an ASW carrier on Yankee Station, but the 10 days on station and 10 days return to Subic cycle didn't fit in with how the USN operated and the idea was knocked on the head. IIUC the Melbourne's magazines carried enough ordnance for each aircraft in the CAG to conduct 4 of its primary missions, so 12 Sea Venoms carrying a pair of 500lb bombs means ~100 500lb bombs were in the magazine.

She was only a wee one.. 'but perfectly formed' as the saying goes...

Certainly, the Chinese have gotten much more than scrap value - from buying her...

You can see why the US has veto provisos placed on the final disposition of mil-spec equipment they sell,
- such as the Australian F-111's retired from the RAAF - being buried, rather than 'scrapped' too...
