Thats a complex cost-benefit question and I doubt anyone here could answer it.

I'll stick my neck out and say stealth/anti-radar technology will be defeated by a technological fix, as historically it always has been.
So really I wouldn't recommend spending a lot of cash on something which always has a shorter lifespan than the salesman tells you.
Has it? As in are there modern systems that could detect F-117s & B-2's easily?

From as far as I know, the F-22 radar cross section is 0,0002m^2, F-35 has one of 0,0015m^2 (which is comparable to the B2 they say), and the F-117 has about double that.

Well, it would be about the same lifetime that the F-16 has had, that's the goal anyway. To have a jet that will be a capable piece of equipment for up to 30 years of service.

I know that F-22s have allegedly shadowed Tu-160s, but its RCS is about 7x smaller than that of an F-35. I have no idea if the Chinese or Russians can detect an aircraft with about the same RCS as a B2 (which the F-35 allegedly has). The problem is, I have no idea how such a concept translates to radar technology.

What I hear is that stealth makes you less visible on the radar, and I get forwarded comparisons to metal marbles and golfballs. What does that actually mean though? That just about every radar system detects it as such? How does that happen? Stuff like that.

Comparing jets to replace the existing fleet of F-16s basically.

As a more basic question how do the listed jets compare, modernizing the F-16 would entail new radar, updated avionics and perhaps a better engine, I'm not sure on the details of the upgrade as those haven't really been discussed.

Gripen NG, Rafale and F-35 capabilities are known. (But as I said before, I don't really know how stealth works and how important it would be in a jet, I know that the operational history of aicraft that did deploy stealth capabilities such as the F-117 and B-2 is near flawless - but how does it work and how does it translate to the modern battlefield etc).

Keeping in mind the jet should have a useful lifespan of 30 years as stated before. Should be able to compete for a long time anyway, having a healthy balance in between cost and capability.
To answer your earlier question, the RCS numbers vary based on the type/band of radar that's going against the particular aircraft. Most fighter A/A radars operate in the X band, most ground radars operate in the L or S bands. Shapes are generally frequency agnostic, but RAM is very frequency sensitive.

You're comparing upgrading a 4th gen fighter to a pseudo 4.5 gen fighter to go up against true 4.5 gen and 5th gen fighters, possibly 6th gen fighters over the next three decades. While the upgraded F-16s are pretty capable jets, I wouldn't want to take one up against a Rafale or F-35. Maybe a Gripen, but not one of the other two. A Gripen and an upgraded F-16 are roughly the same.

And with the RAM you mean for example the coating they use on the F-35? I read reports that they want to use it on the F-22 as well. Can it be that the used RAM is effective over multiple frequencies or is it more likely that it's best on the X band but worse / much worse on the L or S bands?

I also read that the F-35 is supposed to replace the B-2 in certain situations where its very doubtful it can get to its target safely. I would assume the B-2 is most stealthy on L or S bands?

And the shapes have about the same effect on RCS on all bands then yes?

How would new radars circumvent the stealth technology?

Yeah, contender was the Gripen NG though. Supposedly that's quite a step up from it's 'normal' predecessor. How would it fare against a Rafale? And how would a Rafale fare against an F-35? Assuming both BVR and WVR fights.

The point is to have a multi role fighter that's capable for (ideally) the next 30 years. So lifespan is also an important issue as this obviously affects cost a lot as well. Seeing as the F-16s we had have been mainly used for ground support and bombing, this would probably be the primary role of its successor; but it does need adequate air to air capability.

Obviously I can't go into the level of detail you're looking for here. Suffice it to say that the capability of the RAM is linked to the primary mission of the aircraft. It's not like you can just paint the F-35 with F-22 RAM, or vice-versa.

How one fighter performs against another, particularly when talking BVR/WVR, relies as much on the armament as on the aircraft itself. If your missiles don't work well, your BVR capability will degrade. If your IR missile capability is poor, your WVR capability will be poor, as well. Most of the fighter pilots I've spoken with are screaming for multi-spectral passive detection capability (IR/TV sensor), like the Rafale has. That helps quite a bit in getting the edge in a WVR engagement, and RF stealth doesn't matter.

Ahh alright, that makes sense. I'll just assume that considering the role of the F-35 for the USAF (as you're going to be the primary customer of your own product) will mainly be one that's about bombing ground targets while the F-22 functions as the air superiority fighter. So I guess there's more emphasis on L / S frequencies for the F-35.

Just an off question, don't you feel 187 Raptors is a bit few to guarantee US air dominance? I would assume that, especially on missions where the primary role is to protect ground forces or other aircraft numbers have to count for something. Although test results of F-22s vs other aircraft have been very impressive, I suppose it's best to have a decent amount of them in your own arsenal to make sure you eliminate any possible threat quickly as possible. The small number also limits the amount of theaters it can be involved in simultaneously.

Alright, makes sense. Then if we'd pass extensive analysis and you'd have to pick a fighter based on cost/efficiency - being multi role with it's primary goal being bombing missions and supporting ground troops, which one would you bet your money on?

I assume air superiority is less of a deal for us as we've got neighbours on both sides that deploy the Eurofighter, and south of us one that deploys the Rafale.

Doesn't radar cross section also depend on whether an aircraft is flying directly toward or across the radar's path?  For example, a side view produces a larger cross section than the front view, therefore when flying in one should plan his flight path so as to "thread the needle" (depending on the type of radar).

This month, one year since the Deepwater Horizon explosion in the Gulf of Mexico, the Noble Clyde Boudreaux—an ultra-deepwater semi-submersible drilling rig—will start operations off the coast of Brazil. Until a few weeks ago it was stationed in the Gulf.

The two events are not unrelated. Moving the Noble out of U.S. waters is one of the adverse consequences of the Obama administration's overreaction to last year's Gulf spill.

Despite the president's repeated claims that he's been "encouraging" domestic oil production, administration policies have been driving drilling rigs out of the Gulf (six deepwater rigs in addition to the Noble have left the Gulf, with two more possibly on the way out). The overall result has been lower domestic oil production, slower economic growth, job losses and higher energy prices.

In the immediate aftermath of the Deepwater Horizon explosion and spill, President Obama announced a six-month moratorium on new deepwater drilling. According to the administration's estimates, this cost nearly 19,000 jobs in the Gulf states alone—even though federal researchers then cut the figure by an ad hoc factor of 40%-60% to make the results more palatable.

In the months after lifting the ban, the administration slowed drilling permits to a crawl, effectively creating what some have called a "permatorium." Dismayed by the delays, in February U.S. District Court Judge Martin Feldman tried to force the administration to act on seven pending permits, calling the inaction on permits "increasingly inexcusable." Permitting has picked up recently, thanks in part to increasing political pressure, but remains far below pre-spill levels.

In December, the White House reversed course on its own five-year plan to open portions of the Eastern Gulf of Mexico, the Mid-Atlantic and the South Atlantic to offshore exploration. This effectively locks up an estimated 7.6 billion barrels of oil and 36.6 trillion cubic feet of natural gas.

In March, as part of the release of its energy blueprint, the White House touted figures from the Energy Information Administration showing that domestic production had climbed in 2009 and 2010, with production last year at a level not seen since 2003. "So any notion that my administration has shut down oil production might make for a good political sound bite, but it doesn't match up with reality," the president said.

But an uptick in production—such as the one the White House is currently touting in its press materials—cannot be attributed to permits granted yesterday, last week, or even five years ago. Companies spend years developing a well—the process from initial permit to production can take up to eight years. The increased production we're seeing now is mostly due to permits granted before Mr. Obama took office.

This year, the Energy Information Administration forecasts a 240,000 barrels-per-day drop (13%) in the Gulf, and another 200,000 drop next year. The administration blames oil companies for sitting on existing permits. "These are resources that belong to the American people," Interior Secretary Ken Salazar recently complained, "and they expect those supplies to be developed in a timely and responsible manner and with a fair return to taxpayers."

But Mr. Salazar's definition of "inactive" leases includes areas in the Gulf and onshore where significant activity and investment are occurring. By Interior's dubious parameters, the administration considers any company working on critical preproduction activities—such as geological surveys, seismic data collection and environmental analysis—to be "sitting" on its lease.

As the Noble Clyde Boudreaux starts drilling for Brazilian oil—and gasoline prices rise past $4 a gallon—the unfortunate effects the White House could have foreseen from its war on oil are becoming clear to everyone.

Obama's handing the election to Palin on a plate, then again maybe thats the plan.

US economy just a notch above Greece

US finances are in almost as troubled a state as the worst-hit members of the euro zone, economists say, underscoring the pressing need for Washington to reach agreement on how to reduce the deficit.
A gauge of "sovereign risk" from economists at Deutsche Bank placed the United States just behind Greece, Ireland and Portugal among 14 advanced economies.

The report, from economists led by Peter Hooper, warned that a failure to make substantial political progress on deficit reduction "would substantially raise the risk of a bond market crisis".

The warning comes days after Standard & Poor's said that it may lower its AAA assessment of the US, amid a political log jam over debt reduction in Washington, and will intensify market concerns about Western governments' debts.
...
Projections from the Congressional Budget Office suggest that the national debt could rise from 62 per cent of GDP to 100 per cent in 2025 and 200 per cent by 2040, compared with its 1946 high of 122 per cent.

He's not going to want to be stuck with that shit, let Palin and the Republican congress geniuses come up with a plan.

I reckon the Republicans didn't want to win the last election so they put up McFail, from here on its going to be a slow bicycle race to see who can come second.

wat?

Off the top of my head I know the Japanese, Spanish, and Italian dept to GDP ratio is worse than ours and none of them have the resources or the human surpluses we do.
Deutsche Bank's analysis acknowledged that the risk attached by financial markets to US debt remained very low, as demonstrated by the country's modest borrowing rates. That was in part due to the US dollar remaining the premier reserve currency for world governments.

However, the report noted: "Reputation and reserve currency status can be lost, and failure to move US fiscal policy off its currently unsustainable path would certainly increase the risk."
oh okay. Meaningless headline grabber. Got it.

Not sure how thats meaningless but anyway.

China is slowly moving away from the USD as its reserve currency.
If they, and others, stop buying dollars and your debt you're screwed, well and truly.

Im pretty sure German radar can pickup F117s and caught them again when they tried to shadow commercial jets.

As is said below though, I dont think any country in Europe is realistically planning on being in a large scale war with an equal power. Look at the mess in Libya for example, this is all our collective armed forces are specified for and we're struggling with that.

Yup they definitely aren't. Libya is a mess because our common defense, or what it's supposed to be, has been neglected and is grossly being mis-managed. Everyone is cutting everywhere and efforts at integrating the armed forces of different nations have been lackluster at best. NATO contribution is about 80% USA and 20% EU. And you can divide that EU number by the amount of members because they're honestly incapable of cooperating properly.
