With modern digital processing, lower-frequency radars would work just dandy. Their only real use would be counter-stealth, but I am SURE we have them. The design is too easy. You can do it without surface mount parts. If WE have 'em, then we have to assume top-tier potential enemies have them, too.
I am NOT insinuating that the F-35 could not handle a limited engagement by any means. I am saying if it goes up against a top-tier opponent who is expecting it, it might come up quite short. I cannot be proven wrong until I actually am by events, no matter what the argument is.
I don't want to fight Russia or China and I certainly don't want an incident that "validates" my opinion. What I DON'T want is a real need in the future, when this thing is in service, to come up short.
I do NOT have a warm, fuzzy feeling about the F-35 and likely won't unless and until it is proven. When and if it is, I may become a fan. Until then the jury is out.
It is too slow, with too little wing area, and has too little thrust-to-weight combined with a poor fuel fraction (29 - 31% at attack weights). None of those bode well, but it could happen that it works out. Canada is very likely pulling out (
Canada's F-35 Decision Poised To Shake Up Fighter Jet Market).
Others may follow. That does NOT fill me with confidence in the plane and when they lowered the g-limit rather than strengthen it, I started to doubt it. Why fight faster 9-g fighters with a slower 6 - 7-g unit? It makes no sense to me and, apparently, not to Canada, either.
The F-35 first flew in 2006 as a MULTI-ROLE FIGHTER. Don't EVEN try to tell me it isn't. Here is a quote from F35.com ... "The F-35 Lightning II is a 5th Generation fighter, combining advanced stealth with fighter speed and agility, fully fused sensor information, network-enabled operations and advanced sustainment. Three variants of the F-35 will replace the A-10 and
F-16 for the U.S. Air Force, the
F/A-18 for the U.S. Navy, the
F/A-18 and
AV-8B Harrier for the U.S. Marine Corps, and a variety of
fighters for at least ten other countries."
The normal loaded weight is some 49,000 pounds and the thrust, in A/B!, is some 43,000 pounds. Max weight is 70,000 pounds and it goes Mach 1.6 . A 1959 T-38 will do Mach 1.3. That gives the F-35 a thrust to weight of 0.87 for normal loaded weight and 0.61 at max weight. A 1950's fighter was right there. The F-100 had a thrust to weight of 0.55 . The MiG-29 first flew in 1977 and has a thrust to weight at normal loaded weights of 1.09 and it goes Mach 2.25 . The Su-37 normally flies at some 45,000 pounds with a thrust to weight of about 1.4 and it first flew in 1996 as a development of the Su-35 that first flew in 1988. The Su-37 goes Mach 2.35. And these are older airplanes.
Doesn't seem like much of an advance to me, except in avionics, which SHOULD be first rate and above reproach. It ain't the avionics I'm worried about or even Canada is worried about. It's the airframe performance, pure and simple. It doesn't seem to have it with respect to the potential competition.
Only time will tell whether or not the avionics make up for the lack of airframe performance. I hope they DO and look forward to being able to retract some of the above if and when the F-35 proves itself in the arena of combat. It will or it won't. I'm in the cheering section only because we're buying them, not because I'm a fan. If it works out, I may become a fan. If it doesn't, I may not have the chance to change my mind. That is not a comfortable thought.
For the first time in my lifetime, there is NO manned follow-on fighters in the design stage in case the F-35 flops. THAT worries me, too. If you don't plan for a replacement, you surely won't be able to make a change if it is required in the event things don't work out quite as expected. You don't see the Russians doing that, do you? They are flying new prototypes and keeping the possibility of manufacturing them alive and well at a mere fraction of the cost of our "Lightning II."
Why aren't WE exploring alternatives in case things don't happen to work out? Like we used to do? A study isn't a production run and no metal need be cut. But the "next gen" should be taking shape. It isn't. Talk about short-sighted .... we are THERE.
Maybe we need a squadron of Eurofighters ... or Su-37s ... with US avionics in them ... or a military acquisition system that doesn't change things on an aircraft continuously once the contract is awarded. Buy what you spec and be done with it! If you don't get what you want, learn from it and be smarter next time.
