Relax pal.. I just wanted to prove that the above statement is so unuttarably assinine that one can only imagine this guy typed it without even thinking.

The construction details of the Chobham armour developed in the 1960s at the British tank research centre on Chobham Common, Surrey, England, still remains top secret, it has been described as being composed of ceramic tiles encased within a metal matrix and bonded to a backing plate and several elastic layers. The US might have invented Kevlar, but Kevlar is only one component in Chobham

If Chobham is not so secret, why aren't other nations using it? Only the M1 Abrams, Challenger 1, and Challenger 2 tanks have been disclosed as being thus armoured. The armour was first tested in the context of the development of a British prototype vehicle, the FV4211.

As always British governments don't back their inventors when they should be backing them to the hilt.

What about the Leopard II? I think the Germans used a similar armor for their MBTs and still use similar when the Leo II has developed during the years

Among other things such as penicillin, fingerprinting, DNA analysis, hovercraft, VTOL technology, (I could go on) who gave you the jet engine and the Magnetron which heralded the evolution of modern radar? Ring a bell?

VSTOL?? are you sure ?? The Convair/Navy XFY-1 VTOL fighter was the first of its kind in the world ahead of its time, long before the Brits developed the HARRIER. And the "staggeringly brilliant VTOL technology" used in the JSF was designed at Skunk Works, here in California. Jet engine is controvertial the US has also profited from German jet engine technology after the WW2 ,as a matter of fact the real first US fighter SABRE's engine was based on German concept .


Magnetron ?? The first simple, two-pole magnetron was developed in the US . Remember, it was the inventor Percy Spencer who pioneered the mass production of magnetrons. The RADAR was developed by several countries quite independently. The first CXAM-1 antenna went to sea aboard USS TEXAS in 1938 !

You obviously don't understand British humour, his statement was made tongue in cheek as it were.

Yep I'm sure, the Harrier was the first VTOL fighter in the world. The XFY1 didn't get into production, the Harrier did. I think people are still waiting patiently for the JSF

The British shared Whittle's technology with the United States, enabling the engine-builder General Electric (GE) to build jet engines for America's first jet fighter, the Bell XP-59. The aircraft company Lockheed then used a British engine in the initial version of its Lockheed P-80, America's first operational jet fighter, which entered service soon after the war's end.

Percy Spencer built a magnetron in 1945 for use in microwave ovens. The cavity magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field. The 'resonant' cavity magnetron variant of the earlier magnetron tube was invented by John Randall and Harry Boot in 1940 at the University of Birmingham, England.

The magnetron enabled the first effective airborne ground scanning radar to be fitted to aircraft such the Lancaster Bomber.

A lot of these things are a trade off we gets bits of American technology and they get bits of ours. Lets face during the war they got the jet engine, radar, the design for liberty ships also the design for the tail on your rocket planes came from a Martin Baker and the rights to Penicillin amongst many other things.

Like the Miles 52? Miles were ordered to send all their research to the US on the understanding that US research would be available to Miles. None was forth coming, the US stating that their research was classified. The Miles 52 project was ordered to be scrapped by the British Government.

Miles engineers are still bitter (those that are still alive) about being ripped off. One highly annoyed Miles engineer stated "We didn't get anything from the US, because they didn't have anything to send us."

The design of the single piece elevator used on supersonic aircraft came from the Miles 52 research.

The Challenger thus far has the better service record a lot of that is due to the chobham armour.

I did some research on this subject mate.. Current M1 and those being updated incorporate depleted uranium mesh into the formula,before this the Abrams used ceramic armor the formulation of which was also classified-- not layered amor ( though there were some layered components) British Chobham was two generations ago.
Nobody is that stupid to share their latest technology with anyone ,allies included. For example, the radar absorbing stealth panels on British F-35's ,will be imported directly from Lockheed Martin based in US and not manufactured under licence in Britain. They won't give the ingredient to the Brits to replicate
