Aircraft Carriers III

Carriers replenish at sea at least once a week and more often if required, typically every three to four days, so only having a week's worth of jet fuel is no handicap per se.

No dispute with how fine tuned the replenishment process and frequency that routinely happens generally during peace time. However I would ask whether you hold the same conviction of "no handicap" in a conflict situation between long vs short replenishment cycles. Military ships are specs for conflict and not peace time operation even though the ship might never engage in any conflict situation in its lifetime.

Replenishment cycles is an important consideration in any design. For example,
French officials tell Aviation Week that a nuclear carrier needs to refuel its tanks of aviation fuel every 10 days, while a conventional carrier needs to replace its own fuel every four days, a possible hint that the nuclear option may be favored.

you can estimate in your head (and I know, because I botched this estimation in my head Jun 23, 2019 LOL! by confusing gallons with pounds)

about two and a half thousand tons of aircraft fuel is needed for one week of flying one-hundred hours daily;

this favors large carriers in an obvious way, and is one of the reasons I said Friday at 8:29 PM

2 The Government’s View on Article 9 of the Constitution
1 Permitted Self-Defense Capability

ends with "For example, the SDF is not allowed to possess intercontinental ballistic missiles (ICBM), long-range strategic bombers, or attack aircraft carriers."

so let me ask this Forum:
  1. what would be a "non-attack", or perhaps "defensive", aircraft carrier?? all I can think of were converted civilian ships during WW2 (sorry I don't remember any name), but even those of course wouldn't have become carriers if there were no WW2; note typical escort carriers like the USN Casablancas (here I happen to know the Gambier Bay) were not limited to anti-submarine patrols or nothing
  2. even if there were "non-attack" aircraft carrier available now (there isn't), what for would Japan need her?? I don't know the geography of Japan much, but I guess coast-to-coast is 500 km MAX (on Honshu, right?) so a string of airports covering each other should work for the Archipelago protection, I think Japan should leave the rest to the US 7th Fleet

I read somewhere that it was only a political move and that the military branch was never actually asked about the feasibility or viability of this project.

If I was the JSDF I would just call it a multi purpose destroyer when the F-35B is able to operate aboard the ship. Those who have a beef against Japan operating carrier borne fighters will attack it regardless.

As to the idea of offense vs defense, it is a descriptive term of the intended action of the operator and not the platform. A warship is a benign instrument and only becomes offensive or defensive depending on the nature of the actor operating it. This principle applies whether it is a gun, a submarine or a fighter. I don't see why it is somehow a unique issue to aircraft carrying platforms.

and here we are missing the "Whole Point?" defending against what?????

For the first time since World War II, China has an offensive Naval, Air, and Army capability against Japan, so every means necessary are "constitutional" for the first time! lots of small minded thinking here gents, get over it....

and Jura, if you were making the decisions, the F-35A, F-35B, and F-35C would NOT be available to defend Japan, even you should be beginning to see where that would leave us my friend, in a piss poor place overall!
