I'd like to see some quotes on that.  Everything i've read about the J20 suggests it's using last gen "fake stealth" technology.  Nevermind the differencein sensors and in genreal software.

Kasz cannot find the interview it was done when the J20 was first announced. I have read conflicting info at times it seems to be a debate. However most agree the F35 is not a defensive air craft capable of taking on Russia or China's latest fifth Gen stealth fighters.

The F22 still appears to be the best possible fighter. Honestly America and her allies should be mass producing them yes they are expensive more expensive then the F35. But they are the best fighter air craft to date. If we want to spend so many billions of dollars designing a new fighter it should be able to out perform our existing one.

The F35 is a first strike fighter not a defensive fighter. Which is the primary concern of most journalists and analysts I talk to. Read about Australia's recent doubts among other allies.

Unfortunetly their is no currently viable alternative to the F35. We cant get another fighter built fast enough to meet the threat of the J20 by 2020. We aren't going to buy Russia's fighter and the Americans will not sell us F22's.

If we did design our own fighters it would be at least 2025 before any of us could get our new fighters in the air. We cannot wait that long to get a fighter.

Personally as a member of the JSF program I would rally the other members and demand the US sell us F22's and each member use the technology of the F35 to develop our own air craft.

However we do need a fifth generation stealth fighter to challenge Russia's and China's.

Here is a list of the top ten fifth generation fighters.

I think the JSF has been an utter disaster, it's way over budget and far too behind schedule and too much of a one size fits all design.

But the West has committed to it and to turn back now would be even more expensive. No one exactly wants to see $1.5trillion go down the drain. I find it mad this much money has been committed for a strike jet that will only be carrying out strikes against 3rd world countries with rudimentary air defences. If it's in case of a future war against China or Russia, well you're going to need the meagre 187 F-22 for that as the F-35 won't be advanced enough to rout their air defence. They can keep making advances in radar technology to detect stealth (which they can already using radiation detectors) while we are stuck with the the F-35 airframe for the next 30-50 years.

Btw way this link is a load of crap- http://www.mostbeautifull.net/most-advanced-aircraft.html

Only one has been produced (F-22), one is behind schedule (F-35), 2 are still in the prototype stage (J-20 and T-50) and the rest are not even past the design stage so the pictures used are very misleading. For example it uses pictures of the J-20 for the Black Eagle and the Pak FA (T-50) for the Sukoi HAL. And a 4th Gen MiG-29 for the MiG LMFS!

When the J20 was first announced we literaly knew nothing about it and had nothing to go off of but observations of videoclips of it flying.

It was all pure speculation.

I mean if that's all we want....

Maybe I'm missing something, but it seems like everyone is arguing over whether the F35 will be the best aircraft for 1 on 1 dog-fighting; which I didn't think was the goal of the project ...

I thought the point was to have a versatile fighter which could be re-equipped to fill several different roles well; and to have this fighter used across as many allied forces to reduce the number of planes and the amount of equipment that needs to be supported in a joint force.

Realistically, the most likely scenarios for wars involving these planes is to patrol airspace that has already been controlled by the allies. Most likely the a bombardment from sea would cripple the opponents air force, specialized fighters would be used to eliminate all airborne opposition, and then the F35 would be used as a jack-of-all trades to control the airspace and support ground troops.

^Re-equipped is a bad choice of word, F-35 is a platform designed to lower manufacturing and maintance costs thanks to unification of differently-specialized aircrafts. A-la FCS's MGV. Pretty basic and rational idea if not for skyrocketing pricetag that's killing the whole program.

Don't be beleive it gonna be cancelled though despite the cost, it's too big for that (though that's what they said about FCS :D ). Not sure about the actual production series, it might be limited compared to what's been planned.

The real issues with the F-35 are due to bureaucracy and procurement, rather than the actual aircraft.

Not only that, the other aircraft you're talking about - the J-20 and Pak-FA are either crappy or do not exist. The F-35 has already made trials. It takes time to get something like this right.

Its not going smoothly, but it will be worth it in the end. America and her close allies will get a real 5th generation multi-role stealth fighter which will be usable for probably the next 30 years in any potential conflicts.

The J-20 is a joke, and its the only other stealth out there. Why is it a joke? Its about twice the size of the F-35, and it has rivets on the outside of the aircraft. RIVETS! Do you know how stealthy that design is? Its likely only slightly more stealthy than a newer F-15.

Actually the JSF has numerous issues identified by the Pentagon last year in their 'F35 FSF Concurrency Quick Look Review'. Download the pdf and have a read yourself. I bet the Pentagon is regretting their one size fits all requirement. Same airframe to replace F-16, F-18, A-10 and Harrier VTOL.....

And the Pak FA will be out before than the J-20. Russians have already carried out trials before the Chinese.

When will they be at the airshow by my house?

The British government may revert to ordering the jump jet version due to the spirraling cost of fitting catapults to the carrier version which some consider to be superior due to it's increased range and ability to carry extra weapons. Here's a link.
