Spooky Science In The Military

I have read about "entangled photons" and it is definitely a subject beyond my understanding. But, if true, this application to radar detection may have disastrous implications for American military aircraft.
CHINA claims it has a radical new ‘quantum’ radar capable of detecting stealth fighters at great distances. Does this mean our ultra-expensive new F-35 is obsolete, even before we get it?

The RAAF’s first F-35’s will be making their debut Australian appearance at the Avalon air show this week. It’s not a combat-capable aircraft, yet, though the first partially operational US squadron of the type was deployed to Japan earlier this year.

But Beijing state media has boasted its scientists have successfully tested a new type of radar capable of defeating stealth technology at ranges out to 100km.
With a single stroke, such a capability would render the $US1 trillion F-35 Joint Strike Fighter program obsolete. This includes Australia’s $17 billion investment in some 72 examples of the controversial aircraft.

Existing radars cast beams of radio waves into the sky, with sensors detecting reflections from aircraft or ships. The whole point of stealth technology is to minimise such reflections.

But what if the beam was something other than a radio wave?

What if Albert Einstein’s mysterious “spooky action at a distance” could be harnessed?

[...]The implications of such quantum radar are enormous.

If true, it could negate the effectiveness of the single aircraft in which all the West’s defence hopes lay — the F-35 Joint Strike Fighter. This controversial aircraft is 10 years overdue and billions of dollars over budget.

And this is all due to its complete reliance on an ability to fly unseen.

What if it was visible?

It carriers fewer weapons, flies slower and is less manoeuvrable than its predecessors. But all this was justified on the basis that its design was optimised to be invisible to radar.

Take that invisibility away and the F-35 looks much less capable than its counterparts.

This Doesn't Sound Good

Okay, it's the Daily Mail, but I still wonder:
It’s the most expensive weapon in history but America's F-35 stealth jet has been outperformed by a 40-year-old F-16 jet in a dogfight.

A mock air battle was held over the Pacific Ocean between the cutting-edge F-35 - meant to be the most sophisticated jet ever - and an F-16, which was designed in the 1970s.

But according to the test pilot, the F-35 is still too slow to hit an enemy plane or dodge gunfire. So far it has cost the US military more than $350billion.
More here and here.

And this story alleges that the F-35 has been made more vulnerable when engineers got rid of eleven pounds of safety equipment.
The report, conducted by the Pentagon's Operational Test and Evaluation office (OT&E), found that shedding a few pounds from Lockheed Martin's F-35 Joint Strike Fighter (also known as Lightning II) has made the aircraft 25 percent more vulnerable in certain dangerous situations.

The Lightning II lost two safety features in 2008, including the PAO shutoff valve and the fueldraulic system. The PAO shutoff valve weighed 2 pounds and the fueldraulic system weighed 9 pounds, bringing the grand total to an 11 pound weight loss.

However, the new report from OT&E suggests that getting rid of the PAO shutoff valve could lead to a rupture below the cockpit and ridding the fueldraulic system increases the chance of a sustained fire if exposed.
