It's not just the carriers, but the bombers, which should be able to reach Iwo Jima from Hawaii.
Just a single bomber squadron could launch 200 JASSMs from 900km out.
Then you have to figure on some surface vessels launching Tomahawks
Just exactly which air field is setup for bombers in Hawaii? And also Hawaii is 4000 miles away from Iwo Jima. I mean Alaska seems like a more reasonable suggestion.
What is the typical mission availability of bombers like B-2? What % of available B-2s can be available for attack missions on any given day?
Any time you add in tankers (+ enough tankers to support say 10 B-2s). You'd need probably 1 tanker per B-2 at least.You don't have a fighter jet that can escort it that far, so you are now vulnerable to long range AAMs from whatever is stationed at Iwo Jima like J-20A for example.
Plus say 2 carriers, with the aircraft mainly focused on air-to-air, DEAD and escorting the bombers/missiles, although some aircraft may do air-to-ground.
For each carrier, a full sortie of 14 rhinos (rest are used for other purposes) can launch 28 LRASMs per deployment. And these would be rather long missions.
I don't see them targeting the runways. It makes more sense to hit aircraft on the ground (such as large tankers and AWACs) which take some time to launch and infrastructure such as the fuel tanks.
We've seen US military fly over and bomb Houthis. We've also seen Indian lob missiles at Pakistan. Both facing much weaker air defense. How well do you think those attacks went in terms of taking out large tankers and AWACS?
Transport won't stay there. It flies stuff in and then turn around and fly away (we've seen them do this with y-20 already when they flew in HQ-12 into Serbia). They can fly in construction equipment, CIWS, repairing tools, radar systems, SAMs, construction material.
Tankers won't stay there until they setup some level of protection.
Y-20 series should have no issue flying 18 hours a day for a few days.
At most, I see a few days for a combined bomber and aircraft carrier force to level the facilities on Iwo Jima.
Of course, Iwo Jima needs to be worth the effort, which it will be if it starts hosting significant numbers of aircraft.
So the scenarios are:
1. Iwo Jima hosts only a few Chinese aircraft, and is therefore not worth the effort for the US military to attack. But then how useful is Iwo Jima for the Chinese?
2. Iwo Jima hosts a lot of Chinese aircraft. In which case, it makes sense for the US military to concentrate enough forces to break through, then destroy everything at the base.
Hence my view that Iwo Jima is of limited use, at least until China can field a sufficient large air battle network.
That means more J-36 and carrier aircraft, in addition to the aircraft based at Iwo Jima
doing full blockade of East Asia so they can completely sever East Asian supply chain from America and cause US industrial production grind to halt and same with its allies in Europe.
Have some number of longer ranged aircraft say J-20A and UCAVs that can help provide protection for carrier groups, so that they can enforce a blockade of America from the industrial center of the globe.
It takes 40 days to work up 3 carrier groups for a Westpac showdown. Let's say China takes Iwo Jima in the first week and then enforce 30 days of full blockade of America from Asian trading routes. What do you think that looks like?
I remember a few years ago, Patch mentioned that at the beginning of a conflict (assuming the 1IC targets and Guam are disseminated in initial strike) that US military options will be down to bombing from Darwin & Diego Garcia. So, I would think those are realistic options for bombers and that attacking targets 6400km away from Alaska or Hawaii are not realistic options.
