I think you mean tanker(s). An F-22 would still need multiple refuellings to cross the Pacific.
indeed F-22s will need multiple refueling especially as the standard procedure is to follow the tanker and top off whenever fuel gets to about 50 percent (this is to create the largest safety margins possible in case of an emergency divert) but it typically means multiple F-22s following 1 tanker (perhaps more if needed) for the duration of the crossing.to be clear though they basically just follow the tanker to the destination on ferry flights. topping off constantly
Tankers severely limit bandwidth. The problem is that almost all targets of interest in the Pacific are skewed towards China, so longer legged fighters/bombers from Chinese bases as well as land-based missiles can strike almost everything of note but American ones cannot without tankers. They could base closer to China, but that puts them against enormous fires disparity and will suffer very high attrition.
I surmise the hope is for NGAD to have sufficient range so as to not need to need go through the bandwidth compression that is tanker support and still operate from bases in relative safety. China doesn't have anywhere close to this degree of problem with range.
That is not likely to change with NGAD in the sense that there is simply not going to be enough NGAD anyway. The US is already saying the cost and expense of these airplanes is going to make them rare and the magic number being brought about is "100" presuming every one of them is diverted to the war against China (including all the test and training aircraft) that is not exactly a lot to hold off all of China until more can be built (I think it takes 2-3 years to build a modern fighter)
There are going to be losses. and I think a lot of people still struggle to understand that in a full war with China the attrition is going to be nasty no matter what.
if we are going to say the F-22 and F-35 can't do this in terms of range, then its safe to say the F-15s and F-16s and F-18s are not going to be able to do this as well. Which means the entire thing will hinge on NGAD alone. I don't think that is really realistic. It will be a matter of making due with tankers and the US and other allies in the pacific must also be careful to not "trick themselves" into obscurity. caution is important, but if the fear of losses forces everyone to retreat to New Zealand or California, then we might as well not bother. if one looks at the US Marines they are basically making peace with operating in "missile envelopes" they really don't have much other option, which means the US Navy is in the same boat (haha) Some of this is the cold war problem form the 1980s were AWACS, Tankers, and Airfields were all prime targets. There are ways of mitigating some of it, but in the end, people are going to die.
I agree that NGAD will hopefully be able to forgo a lot of tanking and that it will be able to be based far afield, but how far is a big question. and to wrap up my too long post, we must be careful not to trick ourselves into positioning NGAD so far away that it becomes nearly useless in terms of its ability to loiter in important areas when needed. We don't want 12 hours of flying, with 11 of those hours commuting.
The US military which has been very risk averse the last 30 years is going to have to wake up a little and get ready to be punched in the face, early and often. Not there yet at all, but a big fat loss might be the only thing that works I'm afraid. and some things are just geographic realities, we can't ask Japan to move east toward California. if it is a matter of a "meeting engagement over the vast expanse of the pacific, perhaps that is a different equation. but from my point of view, Japan is unsinkable. and so long as its around it forms a base to hit back with.
