1. Depends on the mission profile and threat. Certainly the F-22 fills a gap, but the question is how big a gap and at what cost. I could see a squadron of F-15SE (or even current legacy upgraded F-15's) with support aircraft (jammers, tankers, etc) still being cheaper and just as effective as using a squadron of F-22's by themselves. It is just a matter of what you want to trade. Using the F-22 alone should certainly still be on the table, but the cost-benefit is the limiting factor. In a perfect world with unlimited funding, yes, the F-22 is the best option.
2. As of now, I believe the Navy 2020 architecture is to replace the F-18 mission with a mix of F-35's as interceptor, and UCAS's as bomb haulers. The use of UCAS to do the D3 (Dull, Dirty, Dangerous) missions is the added benefit of using two platforms to conduct the mission the F-18 currently does as a single platform. Not completely sure about all that because the DoD holds that pretty close to the vest, but it seems like the direction they want to go.
1. Let's say you wanted air superiority over Iran, Taiwan or Kashmir or even Alaska for instance and you couldn't get air carriers near enough to be effective, (for whatever reason), I don't think the F-15s could accomplish the mission. Perhaps with disposable fuel pods. At any rate we seem to have unlimited funding these days for most everything else.
2. They must be planning on using the F-18 for several more years, I doubt the F-35 will be in production for quite a while, if ever. Looks like the F-22 could be carrier based and cost considerably less than F-35s.
You would still need something for D3 work but after just a few hours the F-22 can eliminate enemy aircraft, radar and anti-aircraft sites. (At least that's my understanding of F-22 capability without reviewing.)
I wasn't familiar with the UCAS (I guess the latest of which is the XB-47) so I looked it up.
Article on testing.
It's sort of a 'technology is moving so fast it's hard to settle on one set of factors and put it into production.'
I'm not impressed with either payload or sustained air time or range. Call me old fashioned but I hate to see us get totally away from manned aircraft.
When it comes to drones Israel recently announced their newest drone (not feasable for carriers), it has a 24 hr sustained flight time, huge payload with wings about the size of a 707 and is 79' long. (wonder what the mullahs have to say about that?)
From March 4, 2010, yesterday:
The Boeing Company today announced that it has been awarded an $11.4 million contract to supply Laser Joint Direct Attack Munitions (Laser JDAM) to meet the U.S. Navys Direct Attack Moving Target Capability (DAMTC) requirement.
Thanks for you knowledgeable feedback, like the DoD gives a hoot about what I think anyway.
