U.S. is about to deploy F-22 Raptor stealth jets to Europe in a show of force against Russia

F-22 Raptors to be deployed to Europe “very soon.”

The Air Force is about to deploy the F-22 Raptor 5th generation multi-role stealth fighter to the European theater, as a potential deterrent to Russian aggression, Air Force Secretary Deborah Lee James said on Aug. 24.

The Raptor deployment had already been announced in June, when Air Force Secretary, at Le Bourget airshow in Paris, said that Russia was the “biggest threat” her mind, but it now appears to be few days away.

So far the U.S. has responded to the proxy war in Ukraine and to the spike in Russia Air Force activity in the Baltic region with two 6-month TSPs (Theater Security Packages), made up of F-15s and A-10s, and stepping up its presence at regional exercises with NATO allies and partners, attended also by B-52 strategic bombers and A-10 attack planes.

Raptors have often taken part in rotational deployments in the Asia-Pacific region since 2009, but have never been deployed to Europe. It would be interesting to know which airbases are being considered for such deployment that should include 12 aircraft and 200-300 support personnel even though the aircraft will probably not be stationed at a single base but will perform short rotations to a few airports in eastern Europe as already done by the F-15s and A-10s of the previous TSPs (that have visited Germany, UK, Poland, Estonia, Slovakia, Bulgaria, etc.).

Although it was born U.S.’s premier air superiority fighter the F-22 has become a multirole aircraft that has had its baptism of fire in the air-to-surface role during the air war against ISIS: along with air-to-air missiles, the Raptor can also drop Precision Guided Munitions: two 1,000-lb GBU-32 JDAMs (Joint Direct Attack Munitions) or 8 GBU-39 small diameter bombs.

However, according to the U.S. Air Force, during the air campaign against the Islamic State in Syria and Iraq, the once troubled stealth plane has emerged as F-22 is pivotal to ensure the safety of the other aircraft involved in the air campaign: the Raptors act as “electronic warfare enabled sensor-rich multi-role aircraft” that provide key kinetic situational awareness to other aircraft: they escort strike packages into and out of the target area while gathering details about the enemy systems and spreading intelligence to other “networked” assets supporting the mission to improve the overall situational awareness.

Is this China’s next generation stealth fighter bomber?

Most probably, not. However, the artworks  are interesting.

Although China is known to be working also on a new stealth fighter bomber, we don’t know much about the H-20, as the aircraft is believed to be dubbed.

The long-range strike aircraft should be built around the concept of a subsonic, radar evading, flying wing configuration and some scale models have even appeared at aviation exhibitions.

While previous artworks depicted shapes of Beijing’s LRS (long-range strike) inspired to several existing U.S. planes, including the F-117 Nighthawk, the YF-23 and the B-2, a new image has recently popped up on the prolific Chinese Internet.

It shows a manned tactical plane, with internal weapons bay as well as external pylons which carry stand-off missiles. The cockpit reminds the one of the Soviet-era Su-24 Fencer, a side-by-side two-seater.

The “new” shape seems like an evolution of previous concepts, even though it may well be just fan art.

Last but not least, the new stealth bomber is depicted as flying over the disputed Senkaku islands.

What do you think? Can this be Beijing’s response to the American LRS project?

These may be the only F-22’s Achilles’ heels in a dogfight against 4th gen fighter jets

Considered almost unbeatable in the air-to-air role, the F-22 successfully debuted in combat, taking part in air strikes against ISIS targets. But what if the F-22 found a 4th Gen. opponent?

Even though we don’t know much details about them, missions flown by the F-22 Raptor over Syria marked the combat debut of the stealth jet.

As already explained, the radar-evading planes conducted air strikes against ISIS ground targets, in what (considering the 5th Generation plane’s capabilities) were probably Swing Role missions: the stealth jets flew ahead of the rest of the strike package to cover the other attack planes, dropped their Precision Guided Munitions (PGMs) on designated targets, and escorted the package during the way back.

Considered that it could not carry external fuel tanks (to keep a low radar signature), the F-22 were refueled at least two or three times to make it to North Syria and back to the UAE, flying a mission most probably exceeding the 6 – 7 hours flying time.

Raptor’s stealthiness is maintained by storing weapons in internal bays capable to accomodate 2x AIM-9 Sidewinder missiles, some AIM-120C AMRAAM air-to-air missiles (the number depending on the configuration), as well as 2x 1,000 pound GBU-32 JDAM or 8x GBU-39 small diameter bombs: in this way the Raptor can dominate the airspace above the battlefield while performing OCA (Offensive Counter Air) role attacking air and ground targets. Moreover its two powerful Pratt & Whitney F-119-PW-100 engines gave to the fifth fighter the ability to accelerate past the speed of sound without using the afterburners (the so called supercruise) and TV (Thrust Vectoring), that can be extremely useful, in certain conditions, to put the Raptor in the proper position to score a kill.

All these capabilities have made the F-22 almost invincible (at least on paper). Indeed, a single Raptor during one of its first training sorties was able to kill eight F-15s in a mock air-to-air engagement, well before they could see it.

These results were achieved also thanks to the specific training programs which put F-22 pilots against the best US fighters jocks in order to improve their abilities to use the jet’s sophisticated systems, make the most out of sensor fusion, then decide when and to execute the correct tactic.

The Raptor has a huge advantage against its adversaries as demonstrated by the F-22’s incredible kill ratio against USAF Red Air (which play as enemy air forces during exercises) and its F-16s and F-15s, during the exercises undertaken in the last decade: for instance, during exercise Noble Edge in Alaska in June 2006, few F-22s were able to down 108 adversaries with no losses, while during the 2007 edition of the same exercise, they brought their record to 144 simulated kills.

In its first Red Flag participation, in February 2007, the Raptor was able to establish air dominance rapidly and with no losses.

As reported by Dave Allport and Jon Lake in a story which appeared on Air Force Monthly magazine, during an Operational Readiness Inspection (ORI) in 2008, the F-22s scored 221 simulated kills without a single loss.

Still, when outnumbered and threatened by F-15s, F-16s and F-18s, in a simulated WVR (Within Visual Range) dogfight, the F-22 is not invincible.

Raptors refuel

Apparently along with the Rafale, one aircraft which proved to be a real threat for the F-22 is the Eurofighter Typhoon: during the 2012 Red Flag-Alaska, the German Eurofighters not only held their own, but reportedly achieved several kills on the Raptors.

Even though with don’t know anything about the ROE (Rules Of Engagement) set for that training sorties and, at the same time, the outcome of those mock air-to-air combat is still much debated (as there are different accounts of those simulated battles),  the “F-22 vs Typhoon at RF-A” story, raised some questions about the threat posed to the Raptor by advanced, unstealthy, 4th Gen. fighter jets.

In fact, even though these aircraft are not stealth, Typhoons are equipped with  Helmet Mounted Display (HMD) systems and IRST (the Infra-Red Search and Track), two missing features on Raptors.

The Typhoon’s HMD is called Helmet Mounted Symbology System (HMSS). Just like the American JHMCS (Joint Helmet Mounted Cueing System) which is integrated in the U.S. F-15C/D, F-16  Block 40 and 50 and F-18C/D/E/F, HMSS provides the essential flight and weapon aiming information through line of sight imagery. Information imagery (including aircraft’s airspeed, altitude, weapons status, aiming etc) are projected on the visor (the HEA – Helmet Equipment Assembly – for the Typhoon) , enabling the pilot to look out in any direction with all the required data always in his field of vision.

The F-22 Raptor is not equipped with a similar system (the project to implement it was axed following 2013 budget cuts). The main reason for not using it on the stealth jet is that it was believed neither an HMD, nor HOBS (High Off-Boresight) weapons that are fired using these helmets, were needed since no opponents would get close enough to be engaged with an AIM-9X in a cone more than 80 degrees to either side of the nose of the aircraft.

Sure, but the risk of coming to close range with an opponent is still high and at distances up to 50 km an aircraft equipped with an IRST (Infra-Red Search and Track) system, which can detect the IR signature of an enemy fighter (that’s why Aggressors at Red Flag carry IRST pods….), could even be able to find a stealthy plane “especially if it is large and hot, like the F-22″ as a Eurofighter pilot once said.

Summing up, the F-22 is and remains the most lethal air superiority fighter ever. Still, it lacks some nice features that could be useful to face hordes of enemy aircraft, especially if these include F-15s, Typhoons, Rafales or, in the future, the Chinese J-20 and Russian PAK-FA.

Camouflage color schemes: how many Marines can you count in this photo?

Camouflage color schemes are not only important for fighter planes’ survival in combat.

The following image, released by the U.S. Marine Corps shows Marines with Scout Sniper Platoon as they mingle with members of Special Shooting Team at the Hijudai Maneuver Area, Oita, Japan on Aug. 21.

The team were taking part to Exercise Forest Light 12-01, a series of bilateral training exercises with the Japan Ground Self-Defense Force,  practicing stealth and proper shooting techniques.

The effectiveness of camouflage was already proved by the Israeli Defense Forces with a stunning image of the guerrilla warfare specialists from the elite Egoz reconnaissance unit blended with the landscape of northern Israel.

China's J-18 Snowy Owl: Myth or Reality?

Over the past year or so, rumours on the Internet have persisted that China has been building a stealthy STOVL (Short Take Off Vertical Landing) aircraft in a similar vein to the F-35 Lightning II. Pictures of said aircraft are non existant but the rumour mill still persists that it’s either real or will be at some point in the future.

It doesn’t take long looking on the chinese defense forums and websites to see the odd snippet of information, although there is a lot of miss information out there also, of which some could be started by the Chinese government to hide what they are really up to.

The common theme does seem to favour an engine set up similar to the F-35B which in itself wasn’t a new design. Take a look at the Russian Yak 141 and you will see the lift fan at the front and the swivelling jet nozzel at the rear. There is even talk that the engine will be a modified version of what is planned to go into the well documented J-20 when it reaches production. Is this definite? of course not, it doesn’t even appear to be off the drawing board yet and probably will remain so for quite a while (if not indefinately).

So what will the fabled J-18 Snowy Owl look like if it were to take to the skies?

Well, many analysts favour the canted twin vertical stabilisers high wing design in a similar vein to the F-35 with some sort of lift fan at the front just behind the cockpit. It’s interesting to note that the Yak141 had two lift fans one behind the other and it’s suspected that the J-18 would be the same. The big question is: would it sport one or two engines at the rear?  The rendering below seems to favour two engines both with the swivelling nozzels and a smooth low RCS (Radar Cross Section) fuselage internal weapons bays and other stealthy features.

Assuming for a moment the aircraft is real and it’s near to flight testing how would China use it?

It has been widely reported that China’s first Aircraft Carrier has been under going sea trials. Again it has been widely reported that China has a navalised version of the J-15, itself  a copy of the Sukhoi SU-30, which is real and is flying so it is hard to see the need unless there is some sort of unknown plan to build smaller carriers in the vein of the USS Wasp to provide maritime support of amphibious forces.

The STOVL project is going to be a huge technological exercise and that is going to take time. The J-18 is likely to remain rumours and internet chatter for a long time to come, and in true Mythbusters style, this Myth is busted at least for now.
