    Guy with nick Stealth Spy has a lot of info about it, but you should use forum search engine first: http://forum.keypublishing.co.uk/search.php?searchid=559060

    Nothing to write home about… Rockwell Collins AN/ARN-118 TACAN and comm systems, BAe Systems CNIR bird slicers IFF, some cockpit enhancements (PUS-29 HUD and MFI-54 LCD display). Pretty much disappointing, but I agree that there is no need for some kick-ass Zhuk-MSFE installations..

    I agree that this was only necessary modernisation. Just to be more concrete:

    Rockwell-Collins AN/ARC-210(V) (with H.R. Smith 10-150-11 antenna), AN/ARN-147 (VOR/ILS/GS/MB), AN/ARN-153(V) TACAN (with two H.R. Smith 10-222-19 antennas),at cockpit PUS-29M/MS and MFI-54, BAe Systems AN/APX-113(V) (five FS-X FMA and AM-002MH) but only in single seat planes. Two seat have AN/APX-117(V); MIL-STD-1553B serial bus, two flash lights Hella and metric units in the cockpit are replaced with feets and knots. Maybe I missed something, but I think that it is all.

    How can any aerodynamic concept be “out of date” what a silly notion!

    Yes, this one is really up-to-date….

    I never said “aerodynamic concept” but tailess design, or aircraft shape or I dont know which other word I should use in english. I said that tailess design was considered at the beginning of Interim Bomber iniciative, but after requirement of initial operational capability in 2015 it was abadoned in favor of simplier and a bit cheaper version with vertical tails etc.

    Like the F-18 and the Bell X-1??? 😉

    By using term “supersonic” I had in mind something above Mach 3, but OK, next time I should use better words. 🙂 Anyway I still cant imagine high aspect ratio flying wing combined with high speed ramjet.

    Now a bit serious idea – why dont they use some plastic bag or bottle? Its simplier, cheaper and with lower “death weight” during flight…

    more information plz,thanks.

    First of all, this tailess design is out of date. It is based on Lockheed X-44 MANTA (MultiAxis No Tail Aircraft), that was proposed in late 90s. Current design (as shown in link posted by bring_it_on) has greater wingspan, two vertical tails and wing weapons bays.

    Now I know where was the mistake in AWST article (writing about currently revealed Lockheed Polecat). It was not ramjet, but:

    One report refers to the aircraft using engines from an inventory that has been in storage since the 1970s. This almost certainly refers to the General Electric J97-GE-3 engine for the Teledyne Ryan AQM-91 Compass Arrow UAV (a project terminated in 1971). In 1998, a NASA paper reported that 24 J97 engines were in storage at the agency’s Ames research centre. The Compass Arrow exceeded 80,000 ft during tests, the highest unclassified altitude ever recorded for a subsonic jet-powered aircraft. The J97 was rated at around 25 kN and the new UAV is probably a twin-engine design. The new UAV is much larger than the small stealth UAV that has been evaluated operationally in Iraq. That aircraft – believed to be powered by one or two Williams FJ33 engines – has only eight hours’ endurance, like DarkStar, and that is currently seen as inadequate.

    What aiming system is used for this device? IR, AESA radar or just eye-guided? 😀

    Didn’t the crash take place onboard Admiral Gorshkov??

    Were the test trials done onboard Admiral Kuznetsov or on modified Kiev class Admiral Goroshkov :confused:

    AFAIK, Yak-41 doesn’t exist, this is the Yak-141 “Freestyle” VTOL

    OK, to be precise: original plane was named Jak-41, modified multipurpose naval fighter Yak-41M and four ordered prototypes (only two were built “48” and “77”) had designation Yak-141.

    Is that Kuznetsov’s island I see in the background…?

    Yes, this is Admiral Kuznetsov in november 1991 and crashed Jak-41 “77”.

    Europe does not have stealth experience?? What about Lampyridae, TDEFS, FTTU, Dornier LA-2000, Dassault FACE, BAe Replica and that are only manned projects, I am not going to mention UAS and UCAS.

    Last maybe 15 years it is not necessary to have manned full-scale and extremely EXPENSIVE technology demonstrator, when you can do 99 % of basic research by computer simulators and on small radio controled models.

    What not many people know is that the most intensive stealth research was done in Sweden. They came with conclusion, that total stealth is only the fiction. When you have MOVING object, it is always trackable.

    I am not expert on ships, but except LaFayette class (that bought also Saudi Arabia and Taiwan), there is also experimental ship HMS Smyge and its successor Visby class, greece stealthy corvette modified by Vosper Thorneycroft LDT from Quahir and some british designs…

    All I know is that the shelf above the wing is a result of intensive aerodynamic research which conluded that such a feature would be a cheap way of adding performance (what type I am not sure) other than that it looks very JL-9 like and so probably has similar lineage, but the shelf is the primary feature.

    Shelf above wing was designed to replace expensive and complicated FBW system.
