U.S. DEFENSE – Sequestration Cuts Looming

As explained in the video here below, the U.S. military could undergo the most dangerous budgetary cuts ever.

As far as the Air Force is concerned, the 5th-generation fighter aircraft programs had widely been questioned already as a RAND study issued in 2008 (then withdrawn, following the Australian press statements about the JSF war game results), and the umpteen glitches encountered on the F-35 Lightning II shocked the public opinion. Not to mention the F-22 Raptor – its 67-billion-dollar program is questioned too as this amount of money, for instance, would be enough to finance the French defense budget for two years.

The F-22 air supremacy stealth fighter had numerous problems – Flight control software errors, OBOGS (On-Board Oxygen Generating System) investigated after U.S. pilots reported dizziness; and “Raptor cough“, MADL (Multifunction Advanced Data Link) has been delayed, the U.S. 5th generation fighterjets – either JSF or RAPTOR – cannot outperform the 4.5-generation Dassault RAFALE multirole fighter aircraft in DACT (Dissimilar Air Combat Training), and so on. It is the taxpayers who must pay for this.

What will happen? Nobody knows. Leon Panetta, the Secretary of Defense, has already stated that “full sequestration would be devastating to DoD and the defense industry.” The US military power could become a “paper tiger unable to keep up with potential adversaries.” He added later, and – “In effect, it invites aggression.”

Flying an F-22 Raptor – Amazing Experience

The Lockheed Martin / Boeing F-22 Raptor 5th-generation fighter aircraft is a supermaneuverable, or rather a HiMAT – Highly Maneuverable Aircraft Technology – fighterjet which can shoot the enemy before they even see it thanks to its cutting-edge stealth technology:

F-22 Pilots would be Suffering from “Raptor Cough”

According to the CBS news video report below, F-22 pilots would have stopped flying 5th-generation F-22 Raptor for they would have reported HH (Health Hazards) incidents onboard the most advanced fighter aircraft in the U.S. Air Force, and the most expensive ever.

 

“The F-22 has been plagued by a mysterious flaw that causes its pilots to become disoriented while at the controls, from a lack of oxygen.”

 

Thanks to this interview, we now know that a pilot would have touched a tree while flying an F-22 as he may have been suffering from hypoxia (oxygen deficiency in body tissue). Some other pilots reported dizziness, vertigo, and coughing spell.

 

“The Air Force launched an investigation that focused on the plane’s On-Board Oxygen Generating System, or OBOGS which takes air from outside the jet, passes through the engine, and through a chemical process to produce a concentrated oxygen that the pilot breathes – Watch the video:

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.

French FIGHTERJETS and/or PILOTS possibly SUPERIOR

First of all, it is not that simple. Last instance: The “World’s Armed Forces Forum” has recently posted a new topic relating to this Prepa PLS Anglais post: /rafale-vs-typhooneurofighter/ which was edited here on December 20, 2009. It is very clear that this was just a post to pass rumors on to other websurfers who may not have already read/heard such gossips.

This post may have been deemed as a preposterous one among the aviation community. That is why I then posted this post: /french-fighter-aircraft-performance/ in early 2010. Well, in hindsight I ought to add that I had forgotten that confrontation between the French Dassault fighter aircraft with the Eurofighter: the Rafales – there were only two of them according to the report – shot down four Typhoons during an exercise. Yes, twice as many…

The assumption that a Rafale might have shot down an F-22 Raptor left my readers in utter disbelief in 2009. Well, in hindsight again, I ought to add that I had forgotten to quote the Korean balance sheet about the Rafale performance, as I had forgotten that a United Arab Emirates Air Force (UAEAF) Mirage 2000-9 (variant of Mirage 2000-5 Mk.2) flown by a French pilot would have – virtually – shot down an F-22 Raptor as well…

I would never write anything like “an F-5 cannot down any French jetfighter”. Let us get real on this – I guess that either an F-5 or a MiG-21 could down any Mirage 2000 or Rafale. It depends on the radars; the sensors; the weapon systems used that day; the weather conditions; the pilots’ training; and their skills; the distance – BVR or WVR, not to mention autonomy; etc. When I read that some people remain adamant that any Rafale cannot have downed any F-22 Raptor, I think that they have the right to take such a stance. As I have the right to believe that they are wrong in their assertion. All-in-all, everything would be rumors… So, why should they care about them?

The pragmatic Swiss have honestly stated that they would be interested in the French Rafale for they got the results of their demanding NAC tests. However, due to a shrinking defense budget, they may not buy Rafales.

As far as the Brazilian, Emirati, Greek, and Indian (for MMRCA tender) media are concerned, they have already issued – at least once – breaking news according to which their countries would not purchase any Rafale for it would be “too expensive“.

Blimey! Let them buy what they like. I do not know whether it is worth paying for such performance because with these tenders, it is not a question of purchasing warplanes but foreign policies. Nonetheless, I would not be suprised to learn that some French Rafale pilots might be eager to challenge the brand new Chinese J-20 5th-generation fighter aircraft as it is deemed to be less performant than the F-22 Raptor.

If it were to happen – J-20 vs Rafale – the result would remain, as usual, among the rumors.   ;-)

Brand new F/A-18F Super Hornets for RAAF

The Royal Australian Air Force has flown F/A-18 Block-II Super Hornets since December 2010. Australia almost ordered F-35s but following a controversy about the JSF program (Joint Strike Fighter), purchased F/A-18Fs instead of the F-35 Lightning IIs expected in order to replace the old F-111s.

These fighter jets have taken up the F-4 Phantom II’s nickname “Rhino”. The Super Hornet is equipped with an AESA radar (Active Electronically Scanned Array radar – APG-79), and it can refuel other aircraft with its ARS – Aerial Refuelling System. Moreover, it has a low RCS signature (RCS: Radar Cross Section) with its rectangular air intakes, and its maneuverability has been improved thanks to enlarged Leading-Edge eXtensions or LEX.

The F-22 Raptor offer is likely to be turned down. However, Australia might purchase the convential take-off and landing (CTOL) variant of the JSF/F-35A
