FIGHTERJETS compared: Sukhoi T-50 PAK FA vs F-22 RAPTOR

First of all, here is a video on the first T-50’s public display (Moscow – MAKS 2011, August 17, 2011):

The Lockheed Martin/BIDS F-22 Raptor, and the brand new Sukhoi T-50 PAK FA are the current leading-edge 5th generation fighter aircraft. Lots of people would like to assess the capabilities of the two fighterjets. However, no aircraft can be compared regarding its specifications only as fighter aircraft are designed within a wider system – radars; weapon systems; training; and sharing information through data links.

All we know is that the F-22, and the PAK FA are equipped with excellent AESA radars. Though still secret, the Raptor’s stealth is deemed to feature a record-breaking RCS (Radar Cross Section). The T-50, which is to be fielded within the Indian and Rusian air forces, might be equipped with anti-AWACS missiles. The Chinese Chengdu J-20 has not disclosed much information so far, but it will be interesting to this new 5th-gen fighter with the two other aircraft.

Video – SAAB 35 DRAKEN tested as an interceptor

The Swedish-made Saab 35 Draken was a second generation jet fighter. 644 of them were built. This fighter aircraft used to fly during the Cold War as early as 1955, and entered in service in 1960.

Maybe her particular double-delta shape was worth calling it “Draken” which means “kite”. She was more an air defense aircraft than a dogfighter aircraft.

She retired from the RDAF, the Royal Danish Air Force in 1993; from the SwAF, the Swedish Air Force in 1999; from the FIAF, the Finnish Air Force in 2000; and from the AAF, the Austrian Air Force in 2005.

Hereafter an interesting video featuring a Saab 29 Tunnan (Flying Barrel); a Saab 32 Lansen (Lance); and a Draken momentarily as an interceptor; with her rate of climb nearing 35,000ft/min, she could reach FL650 – more than 20 kilometres above the earth – to hit her target:

RAFALE, GRIPEN, TYPHOON for Swiss AF – Purchase postponed!

08/26/2010 Article adapted from AVIANEWS

As far as the Swiss Air Force is concerned, there has been two options so far – the choice of new fighter aircraft or postponement thereof, the second alternative has been chosen. You will find hereafter the Avianews webmaster’s analysis:

This is the Swiss Federal Council Message:

“However, given the current state of federal finances and priorities taken as a whole, the time of acquisition is postponed to no later than 2015. The Federal Council decided on the proposal of DDPS (Federal Department of Defence, Civil Protection and Sports) to postpone the replacement of 54 obsolete combat aircraft F-5 Tiger Air Force. The Head of the DDPS, Ueli Maurer held a news conference on the postponement which is expected to last at most until 2015. The Federal Department of Finance and the DDPS together confirm by the end of 2011 the conditions for an acquisition during the second half of the decade. ”

The reasons for non selection:

First, this is an organizational problem from the financial organization of Armée XXI. Remember, the people had voted for the new military organization with a comfortable 70% “yes”! id est a military downsized with a budget of only 4.3 billion Swiss Francs now. However, the parliament has never put forward this budget that painfully reaches 3.6 billion. The Swiss People is reportedly disappointed by such loss of income, and deception as well.

No F-5 replacement:

Replacing the F-5 is out of the question anymore but to get prepared for the next generation of F/A-18 from 2025. Consequently, there is more urgency to acquire a large number of aircraft as a whole block but split into several ones.

Consequences:

The losers in this case are the Swiss industry and jobs. Indeed, if the cost of a fighter plane is expensive, the returns on partnerships to “Offsets” were significantly higher and would have revitalized both the Swiss manufacturing industry and employment.

Competitors:

The three companies will meet in a few years for a new offer and therefore cannot comment on this “no choice”!

Dassault must be disappointed for they would certainly have won the contract with his Rafale. The version of the Rafale-04T was proposed with more powerful engines, the wiring for the METEOR missile, the new targeting pod Damocles XF and the brand new IDM (Improved Data Modem).

It bodes well for Saab because they now may complete the Swedish version of the Gripen E / F (NG), whose development is not completed yet and find a buyer with the Swedish Air Force (SwAF). Indeed, it must order the Gripen E / F by 2015.

EADS Eurofighter will be able to finalize its AESA E-scan radar and they are likely to reduce maintenance costs of the aircraft as promised this summer to the Switzerland Economy Minister Doris Leuthard at the ILA Berlin Airshow.

… To be continued …

RAFALE or EUROFIGHTER to become next Indian Air Force fighter jet according to Indian media – Russian and US media deny

Amazing rumours have spread for a couple of days regarding the MMRCA (Indian Air Force Medium Multi-Role Combat Aircraft) or the MRCA Tender which is an ongoing competition to supply the Indian Air Force with 126 Multi-Role Combat Aircraft maybe up to 189 fighter jets.

The Indians have considered 6 bidders so far:

Typhoon (European Eurofighter Consortium)
Rafale (French Dassault)
MiG-35 Fulcrum-F (Russian UAC subsidiary RSK-MiG)
Gripen NG/IN or JAS 39 (Swedish Saab)
Super Hornet F/A-18 E/F (US Boeing)
F-16IN Fighting Falcon (US Lockheed Martin)

As you can watch the video below, two fighter aircraft have been quoted as finalists for the last stage: The EUROFIGHTER-Typhoon and the RAFALE.

However, American and Russian media deem that such statement cannot be true. Official results should be announced soon. Well, wait and see…
