The UK and Israel, Italy etc shouldn't be too concerned, the Chinese will soon get their hands on it and reverse-engineer it to work with their J-xx's , the Euros can simply buy it from them !! :roll:

IAI, EADS discuss adapting A320 for airborne early warning
IAI and EADS officials see a huge market opportunity for AEW technology, Reshef says, amounting to more than $10 billion over the next five years. IAI expects that an A320-based system could capture 30-40% of the market share, he says.
The first such A320 AEW platform could be available for service entry within three to four years of a contract award, Reshef says. The installation process "would be quite short in comparison to other programmes", he adds.

Bulava fails Test
Russia's error-prone Bulava intercontinental ballistic missile has suffered its eight failure in 12 tests, the Defense Ministry said Thursday, dealing another blow to Kremlin hopes that the sea-based weapon would become a cornerstone of its nuclear arsenal.

In a written statement, the Russian Defense Ministry said the missile failed in the third stage of its trajectory.
"Unstable work of the engine of the [missile's] third stage was detected by the monitoring systems," the statement said. "The causes of the technical error are being established by a state commission."

It is funny how that class of missile is immediately classified as error prone, while US Tomahawk missile is state of the art!
Two submarines and a number of surface ships fired Tomahawk cruise missiles during the Gulf War. According to initial US Navy reports, of 297 attempted cruise missile launches, 290 missiles fired and 242 Tomahawks hit their targets. But TLAM performance in Desert Storm was well below the impression conveyed in DOD's report to the Congress, as well as in internal DOD estimates.

(8/12)*100 = 66.67% Failure Rate

(55/297)*100 = 18.52% Failure Rate (including failure to hit designated target which could possibly include a greater than design/acceptable CEP)

At it's current Failure Rate if you were to fire the missle 297 times (same figure as Tomahawk from your post) you would have almost 200 failures vs 55 for the Tomahawk.

That's almost 3.5 times the failure rate of the Tomahawk; please try harder to conceal your bias next time.

Thanks,

X-51A WaveRider Gets Airborne
The B-52 climbed to the planned launch altitude of 50,000ft during a 1.4h flight that checked out systems and telemetry. The next flight, planned for mid-January, will be a full dress-rehearsal for the first of four planned X-51A hypersonic test flights.

I searched for the reason behind spiral thing...but was not that successful....except I found...
"The spiral suggests the object came off course and balance and entered the spiral movement. Leaking rocket fuel could account for the blue light.

Seeing the number of failures of Bulava probably Russians are trying out a number of new technologies. It must have a ultra maneuverable warhead to create such a pattern even though it failed.

Re: Technical Information & Link Repository

It was posted by me only.....in the above forum....the papers talk about failure of Anti Tank Missiles when the mid-body wings are damaged...!
Vertical mid-body wing damage had little effect on performance while damage to horizontal and adjacent mid-body wings resulted in significant failures. The failure mode demonstrated was not a large increase in CEP but rather seeker failure due to excessive roll and yawing of the airframe. This highlights that the seeker and seeker gimbal performance are significant factors in an ATGM’s ability to tolerate field handling damage.
perhaps this explains speculations that MISSILES ARE ROLLING AND THERE WAS FUEL LEAKAGE...WHICH CAUSED AND RARE BUT ILLUSIVE [HUH???] DEMONSTRATION....!

Well one is comparing failure rate of an operational deployed missile versus a one under testing or in development stage.

One is a cruise the other is an SLBM

Sir, That is photo is clearly PHOTOSHOPPED. :) the video tells how it actually looked. Well it seems that fuel was leaking out from lower side of the missile

F-22 Raptor: Procurement & Events A GOOD READ for those who would want to compare it with PAKFA/FGFA
The F-22’s central integrated processor (CIP) offers the equivalent of 2 Cray supercomputers, used for “sensor fusion” that aims to put all of the information the plane is gathering into one simple display. Furthermore, a radical design departure embeds passive sensors for various wavelengths all around the plane’s structure. This greatly improves first detection ability, even with its radar off; and the combination with sensor fusion means that F-22 pilots are almost certain to know where their opponents are, long before the reverse is true.

The F-35 shares this approach. It uses even more modern internal electronics, and a wider array of sensors. Including infrared and TV sensors that can be used to target both aerial and ground foes at the same level as top-end targeting pods and air-to-air IRST (Infra-Red Search and Track) systems.

“I can’t see the [expletive deleted] thing,” said RAAF Squadron Leader Stephen Chappell, exchange F-15 pilot in the 65th Aggressor Squadron. “It won’t let me put a weapons system on it, even when I can see it visually through the canopy. [Flying against the F-22] annoys the hell out of me.” :D the things a 5th GEN AIRCRAFT CAN DO

Craig,

LM's company mag dedicated the main topic to the F-22 - in the late 90s. That article was a few pages long and gave a year by year (IIRC) development of the F-22. F-22 took 10 years to finalize - each year there was a substantial change in the plane.

I was not the one comparing; I was just bringing the irrational comparision to it's logical conclusion.

Expect stories of how the Pakistani pilots shot down all the Rafales and Eurofighters, and could have got the F22s also, but were told not to do so to spare the USA embarrassment.

Test Vehical for Brahmos 2 ?

Timeline for new hypersonic missile development?

Russia will develop a target missile with a strait-flow engine in two or three years. The missile may be the prototype of a hypersonic aircraft, a Russian defense sector source told Interfax-AVN.

“The target missile development started in 2009, and the entire works will take three years. Documentation is ready,” he said.

The target missile “may eventually develop into a hypersonic vehicle, because it is easier to test prospective technologies this way,” he said.

“Key elements of the new engine were tested in the aerodynamic tube of the Central Aerohydrodynamic Research Institute this year. A model of the target missile will be tested in 2010,” the source said.

KUALA LUMPUR: Malaysia will take action against air force personnel involved in the theft of a 14.5-million-dollar fighter jet engine sold to a South American company, according to reports Sunday.
M AF operates Su -30 MKM and F/A-18D and some MiG-29N Fulcrums .

the stolen engine could be either an thrust vectoring Al-31FP turbofan (of Su -30 MKM) or F404-GE-402 of F/A-18D both of which ordinarily cost around $3-5 million (leaving out the fairly ordinary Klimov RD-33 of MiG-29N ).

now the question is who will want to buy an engine for $15 million when they are ordinarily sold for 3 times less ?

PS: AoA i got my 72 with this bost onlee
now having visions and pheeling of Djannat :oops:

believed to have eventually ended up with a final purchaser in the Middle East
The engine, used for single-seat fighter and reconnaissance jets, is believed to have eventually ended up with a final purchaser in the Middle East, the New Straits Times said.

From the Link
...
The newspaper also said police had arrested four individuals, including the buyer, the seller and air force personnel who assisted in stealing the engine, used as powerplant for a single-seat fighter and reconnaissance aircraft.
