F-22 Raptor to join naval drill in Korean seas

Four state-of-the-art U.S. stealth fighters will join a massive combined air and naval exercise to be held by South Korea and the United States in the East Sea later this month in a show of the allies’ strong deterrence plans against North Korean provocations, South Korean and U.S. defense officials announced Tuesday.

The plan was made public after consultations between Defense Minister Kim Tae-young and his U.S. counterpart Robert Gates in Seoul. The two defense chiefs discussed a series of combined maritime and air readiness drills in waters around the peninsula in the coming months.
...................

About 200 fighter jets, and naval aircraft and helicopters will fly training missions in and around Korea. In addition, approximately 20 warships, including the U.S. nuclear-powered aircraft carrier USS George Washington, the South Korean Navy’s 14,000-ton Dokdo large-deck landing ship, and attack submarines will participate in the exercise.

The deployment of the F-22 Raptor, the world’s most advanced aircraft, will be symbolic in heralding the solid and broader alliance of the two governments against emerging regional threats, including a North Korean provocation, said Maj. Gen. John A. Macdonald, director of the ROK-U.S. Combined Forces Command’s operations bureau.

“The Raptor is the capability that we brought here to help in the defense of the Republic of Korea. It is part of the ROK-U.S. alliance,” Macdonald said.

“We will have four Raptors to participate in the exercise, and they will be involved in strike operations that will take place on ranges.”

This will be the first time that the “fifth-generation” radar-evading aircraft will participate in exercises with South Korea. The F-22, built by Lockheed Martin, is equipped with an active electronically scanned radar for cruise missile detection and is capable of evading advanced air defenses to bomb ballistic missile launch sites.

The single-seat fighter can fly at a maximum speed of Mach 1.8 and has an operational radius of 2,000 kilometers. Its weapons systems include AIM-9 Sidewinders and Joint Direct Attack Munitions (JDAM).

.............

TIME FOR THE CHINESE INTELLIGENCE TO WORK OVER TIME....The RUSSIANS won't be far behind either!!!! Time to see how good the S3/400 MDS really is! Good exercise to practice with L-band radars to see how far can they detect aircrafts and IF it is able to detect F-22!!!!

Canada may back out of F-35 buy

C anada won't be required to sign a contract committing it to purchasing new multibillion-dollar stealth fighters until 2013, opening the door for any future government to back away from the proposed deal if needed.

The Conservative government's decision in mid-July to spend an estimated $16 billion on the Joint Strike Fighter has sparked controversy, with opposition parties questioning whether the purchase is needed at a time when the country's deficit has ballooned to $50 billion.

PICTURES: Venezuelan pilots escape K-8 trainer crash
By Craig Hoyle

Venezuela has lost its first Hongdu K-8 to an accident, just four months after accepting its first batch of the jet trainer and light attack aircraft.

Both crew members survived the 21 July accident, ejecting shortly before the aircraft came down new Barquisimeto, around 360km west of Caracas.

Venezuela’s air force in mid-March took delivery of its first six K-8s from an 18-aircraft order with China, and the last its remaining examples had been due to arrive in-country this month.

Designated as K-8Ws, Venezuela’s aircraft can also be armed to perform light attack duties.

President Hugo Chavez early last month announced that more than $80 million had been set aside to acquire a further 22 K-8s, in a move which will enable the air force to retire its aged Canada VF-5A fighters.

So much for the 'reliability' talk of the Chinese jets in the Farnborough 2010 thread !

F-35 - take it or leave it

Just imagine Israel's position today had the Lavi fighter jet project not been canceled.

Now they are staring at a $3 billion price tag for 20 F-35s. They said Israel should not be developing military platforms but only accessory systems to be mounted on the platforms. Now Israel will not be allowed to mount Israeli systems on the F-35.

We would have to look for partners who are prepared to invest resources in such a project, who have the necessary technological capability, and who are not involved in the F-35 project. Are there such candidates? In theory, yes. France, with a great aeronautical industry, chose not to participate in the F-35 project. India, with a considerable aeronautical capability and a meteorically growing economy, might be another candidate.

I am not trying to defend the K-8! There have been quality issues brought up by Egypt, Myanmar etc etc. However, attrition hasn't been a big concern for the K-8. in spite of being used widely and in big numbers and for some time. I don't believe, one crash will dent the "reliability" of the K-8 among the fraternity.

There is a huge market for cheap intermediate/advanced trainers. China exported close to 300 K-8s over the past decade. We should come up with our HJT ASAP and show case it. If we can price ours between that 3-5 million and provide good QC, there is still a big market out there.

Also it is high time that India developed advanced trainers. The Chinese are again far ahead (with a flying prototypes, read L-15 or JL-9)! The price is expected to be half of BAE Hawk. We certainly have the know how! Wonder when we will atleast start planning for such a trainer? When will we start seeing the market?

Two Russian Tu-95MS Bear-H strategic bombers have carried out a record-breaking 40-hour patrol over three oceans, an Air Force spokesman said.

"The Tu-95MS bombers carried out patrols over the Arctic, the Atlantic and the Pacific oceans and set a new flight duration record of about 40 hours, exceeding the previous record by four hours," Lt. Col. Vladimir Drik said at a news briefing on Thursday.

The crews practiced instrumental flight and carried out four in-flight refuelings from Il-78 aerial tankers, the official said.

Lockheed Martin is going to preserve F-22 tooling after production ceases in 2012 to allow for service life extension as well as to give the USAF an option to order more F-22s in the future..this will give Japan and Israel some hope as well that maybe, just maybe they can still keep asking for F-22s beyond 2012.

RoKAF doesnt come out looking too impressive from that strike eagle article
- no aesa on these costly planes- only a modified apg63(v1)
- no aar tankers hence no ability to deploy across the pacific to nellis - why couldnt they use drop tanks and fly via hokkaido, aleutians, alaska?

makes me think our IAF does certain things daily without comment which more of these "small chi chi munna" types dont even try.

same for IN sailing a couple of ships through a hurricane in the china sea which amazed the hosts!

The aesa point struck me too given the exorbitant cost of the strike eagles that ROKAF has gone for also now they have two different injuns in service the 129 and the 110 IIRC one of em is in commonality with the solah that they have.

I think they may not have taken the drop tank route because the strike eagle is a relatively new platform for the ROKAF and I dont believe they have done any long range flights yet, plus from a cost perspective its mucho easier to take the newer planes to red flag and then back to korea than the other way round considering the delivery itself was in KHAN....we live in the world of bean counters onlee...

Singha · Post by **Singha** » 31 Jul 2010 10:17

I guess at full mach2 speed, the eagle will cross all of korea in a few mins only...have to wonder where they train....most strikes on Noko would be <10 min ride from base. N-S, Soko is only 430 km max and E-S around 200km.

so they hardly need any drop tanks to smack Noko, all those weapons stations on strike eagle can carry bombs.

Turkish Medium Altitude Long Endurance Anka UAV

The Anka UAV, which has a 17.3-meter wingspan, is eight meters long and has a maximum payload of 200 kilograms, will make its maiden flight in October and reach initial operating capability with the Turkish Air Force in September before reaching full operating capability in December 2012, TAI said at the Farnborough Air Show.

TAI sister company Aselsan is supplying the UAV's EO/IR pod and SAR/GMTI radar, while TAI is providing a ground control station, a mobile set-up for exploiting imagery and remote visual terminals supplying real-time imagery to ground troops.

The Anka will have automatic take-off and landing and autonomous flight capabilities, as well as retractable landing gear, a heavy fuel engine, line-of-sight navigation with a range of 200 kilometers and deicing capability.

"There is a high interest in this UAV from export customers and we are prepared to invite them to join the program at observation or associate level," said TAI CEO Muharrem Dortkasli.

GPS guided weaponry for Mirage 2000-D of the French Air Force

Until 2009, the Mirage 2000 D, two-seat fighter-bomber, was equipped with a mode of laser-guided bombs or missiles. Two years ago, the General Delegation for Armaments (DGA) has decided to join the GPS-guided laser system to its entire fleet of 80 Mirage 2000 D The modification work began at the end of last year. In total, two hundred kits (for every bomb and missile) will be modified. The whole operation should be completed in 2015.

Christopher Sidor · Post by **Christopher Sidor** » 02 Aug 2010 12:26

The way I see it, the future of IAF is in UAW and not in any 5th Generation Fighter aircraft. With progress in swarm intelligence, enhanced operating radius, UAW will be a superior choice compared to a Fighter Aircraft. Who knows it is even possible that the 6th Generation Fighter Aircraft will probably be a UAW with limited AI.
Moreover the economics and human factors make UAW more enticing compared to a human Fighter aircraft. With air refueling there is nothing stopping a UAW to remain airborne for more than 24 hours. This feat cannot be matched by a human manned fighter aircraft. A UAW can be sent to places where we would not fear about our fighter pilots getting shot down. For example in Kargil, if we had lethal UAW, it would have made life much easier for us. We could have easily sent it across the LoC. If it gets shot, big deal, replace it with another UAW. Also it takes time to train a figther pilot. It costs money to keep him or her in service. And if he or she gets shot down in enemy territory, then we have to find a replacement. With a lethal UAW it will keep fighting till the enemy is destroyed or it gets destroyed.

A lethal UAW will be able to provide a more effective tactical air strike capability to our military. It can be transported along with our infantry and mechanized forces. We can deploy two UAWs per destroyers or battleships, which can be lauched by a catapult and captured by a hook for landing. This will increase the strike capability of our naval ships. We can have a group of lethal UAW always in the air, so that in case of a fresh terrorist strike, then can respond against our enemies within minutes, and not days as is the norm now. The possible list of applications for lethal UAW are only limited by our imagination.

The only problem that I foresee is that currently, lethal UAWs are perfect fit for terrorist targets or small Special Ops. But for large scale warfare, they might not be that capable. But this will change with advancement in S&T. Maybe instead of MCA and LCA India should be concentrating on a lethal UAW program.

Next-Gen Jammer Key To F-35 EffectivenessNext-Gen Jammer Key To F-35 Effectiveness

...............
New integrated air defense networks — some of them fielding improved versions of the S-300 family like the NATO-dubbed SA-20 and SA-22 — are already on the way. The antidote for these long-range, high-altitude missiles is expected to be the NGJ, which is to be fielded in 2018.

There have been two directions of research in the exploratory stages of NGJ. One is the world of elegant, low-power techniques using tailored waveforms to unlock enemy electronics. The second is the use of extremely well-directed, high-power radiation that can incapacitate enemy electronics.

“We do need to go to smarter techniques like coherent jamming, where you spend a substantial amount of time listening and then respond in-band in a more deceptive construct than just simply putting out jamming noise,” says Capt. John Green, the U.S. Navy’s program manager for airborne electronic attack and the EA-6B Prowler.

Well I guess it is a world of claim and counterclaim while NGJ is advertised to be an effective jammer against SA-20/22 , the advertorial from SA-20 will tell you it can remain effective in all current and future jamming conditions and defeat stealth.

NORAD and Russian Air Force plan cooperative air defense exercise

PETERSON AIR FORCE BASE, Colo. - The Russian Federation Air Force and the North American Aerospace Defense Command will conduct a first-ever cooperative air defense exercise.

The civilian air control agencies of Russia (Federal Air Navigational Service) and the United States (Federal Aviation Administration) will also be involved in the exercise along with the military air operations centers at Elmendorf AFB, Alaska, and Khabarovsk, Russia.

The exercise, named VIGILANT EAGLE, will take place on or about Aug. 8-11 and involves Russian, Canadian and U.S. Air Force personnel operating from command centers in Russia and the United States.

This exercise is authorized under a cooperative military agreement signed by the presidents of the Russian Federation and the United States of America. The agreement tasks NORAD, the bi-national U.S. and Canadian command, and the Russian Federation Air Force to conduct a live-fly exercise for up to five days.

It will consist of two international flights: one originating in Alaska and traveling to the Far East followed by one originating in the Far East and traveling to Alaska. Both flights will follow the same route.

The basic premise is that a U.S. flagged commercial air carrier on an international flight (Fencing 1220) has been taken over by terrorists. The aircraft will not respond to communications. The exercise scenario will create a situation that requires both the Russian Air Force and NORAD to launch or divert fighter aircraft to investigate and follow Fencing 1220. The exercise will focus on shadowing and the cooperative hand-off of the monitored aircraft (Fencing 1220) between fighters of the participating nations.

Airborne warning and control aircraft (AWACS E-3B and A-50) from Russia and the United States will be involved along with fighter-interceptor aircraft and refueling aircraft from both countries.

This combined exercise moves us forward in the development of cooperation between the Russian Federation Air Force and NORAD in preventing possible threats of air terrorism. This exercise provides the opportunity to cooperatively detect, track, identify, intercept and follow an aircraft as it proceeds across international boundaries.

State tests of Su-35S is coming near
13/08/2010/Red Star

The company "Sukhoi" completes preliminary testing of a new multipurpose fighter Su-35 and plans this fall to provide an aircraft for the state joint tests (ICG). Su-35 as a promising Complex Frontal Aviation (PAK FA), will ensure the safety of the sky of Russia in the new century.

According to Interfax-AVN director of the Su-35, the chief designer of the Sukhoi Design Bureau Igor Demin, bringing the aircraft to the ICG can be expected in September or October. According to him, now in flight testing involved two Su-35 fighter. At the stage of ICG their number will be increased to six. The third car will take off in the fourth quarter of this year.

As Igor Demin, a program of flight tests of the Su-35 provides for the implementation of a fairly large number of flights. This is due to the fact that this machine set a lot of new systems and components, apply the most modern aircraft weapon.

Earlier it was reported that during the preliminary tests multi-purpose fighter Su-35 is fully confirmed the declared characteristics. In particular, it has been a top speed at sea level 1.400 km / h, at a height - 2.500 km / h, ceiling - 19 thousand meters range target detection in the "air - air - more than 400 km, which is significantly higher than figure standing in the arsenal of aircraft.

Company Sukhoi is also negotiating with foreign clients interested in re-equipping its air force. Production deliveries of Su-35 for export are planned for 2012.

Su-35 - deeply modernized super maneuverable multifunctional fighter generation "4 + +". It uses a fifth-generation technology, providing superiority fighter class.

Distinctive features of the aircraft are new avionics based on digital information management system that integrates avionics systems, new radar station (radar) with a phased array with long-range detection of air targets with an increased number of simultaneously tracked and fired targets. The airplane is the new engines with increased thrust and turning thrust vector.

Su-35 has the broad nomenclature of weapons large, medium and short range. It can be operated air attack antiRLS, antikorabl general purpose, adjustable, bombs, and unguided weapons.

Radar visibility fighter planes compared with the fourth generation is reduced by several times due to an electrically conductive coating cockpit, causing the radio absorbing coatings and reduced the number of speakers sensors. Resource aircraft - 6 thousand flight hours, lifetime - 30 years of operation, the designated resource engines with controlled nozzle - 4 thousand hours.

Kh-101/102 from Yefim Gordon Book on Russian Air Power

The flight testing of the Kh-101 has already been completed. This missile weighs some 2,200 - 2,400 kg , the weight of warhead is 400 kg. According to press reports, the Kh-101 has a maximum range of 5,000-5,500 Km a variable flight profile at altitudes ranging from 30 - 70m to 6000m , a cruising speed of 190-200 m/s and a maximum speed of 250-270m/s. It can well be classed as a low-observable flying vehicle because the radar cross section of the Kh-101 is 0.01 m2. The missile is equipped with an electro-optical system for correcting the flight trajectory and with a TV guidance system for terminal guidance. This ensures the hitting precision with a deviation of some 12- 20m.

The upgraded Tu-95MS can carry eight Kh-101 missiles on four wing pylons. The same missile will also equip the upgraded Tu-160 which will be able to carry six missiles in each of its two weapons bays total of 12 Kh-101 or 102 missile. The highly accurate guidance system of the Kh-101 and its combined HE/fragmentation/penetrating warhead will enable one modernised Tu-160 to fulfil tasks previously achievable with an entire regiment of bombers. The upgraded version of Tu-22M3 is capable of carrying four Kh-101 missiles or six to eight Kh-SD

An-70 design to be see “upgrade” before mass production

The Antonov An-70 military-transport aircraft will be upgraded and fitted out with new equipment, said Dmitry Kyva, president and general designer of the Ukraine base Antonov Corporation

“We have launched a program to upgrade the An-70 and we have signed a plan and an adjusted technical assignment with the customer. New hardware components and avionics will be installed, he said.

“Without changing the algorithm mechanisms of control we are changing equipment. The plane will have a new look with modern digital systems,” he said.

Russia and Ukraine agreed in 2009 to continue modernizing the An-70 aircraft and carry out further tests.

The An-70 is capable of carrying 300 servicemen or 20-30 tonnes of military hardware, and land on a 700 meter-long runway, Kyva said.

It compares very favorably in terms of range, cargo lifting capability and size of the cargo compartment to its rival, the European military-transport plane A400M, recently demonstrated at air shows in Paris and London. The catalogue price of the European plane is 160 million euros. “The price of our plane is 50% lower,” Kyva said.

It is estimated that over 10 billion euro was spent making the A400M. An additional 3-5 billion euro is needed to fine-tune the aircraft.

I was reading Yefim Gordon "Russian Strategic Aviation Today" , it seems when the Blackjack went on their long range flight and landed in Venezuela to continue with the exercise. On the second day of the exercise the US deliberately shut off their GPS satellites over the region to deny the Russians any GPS signals.

Seems like Unkil can selectively shut of GPS over a given region , much more critical we have our own GAGAN going asap.

Lalmohan · Post by **Lalmohan** » 18 Aug 2010 15:40

the GPS satellites fly a pole to pole route i think, which means that the entire longitude band around venezuela would have to be degraded/shut off, which means large chunks of the US would be affected...

they can also degrade the signal/time stamp to introduce larger errors, with i believe the relevant filters in their own receivers

happy to be corrected on this

Austin · Post by **Austin** » 18 Aug 2010 15:58

Not sure how they could shut of GPS signal but to quote Gen Zhikharev Chief of Staff Long Range Aviation " We had to bring in our ground beacon and it weighs several tons. Additionally I plotted a GPS track [ for the approach to base ]. By the way on the second day of our deployment the Americans deprived us of the ability to use GPS - they simply shut down the satellite signal"

they must have some selective degradation of time stamp (hence position calc) capability on selected sattelites, and a code to prevent US MIL GPS from having the same problem

civilian error band is +/-20m? i think Mil is +/-0.5m? If you can degrade the civil to +/-100m that would mess up any use of GPS for approach and landing purposes

With SA turned off, errors for civilian use will be around +/- 5m, less with a WAAS system (like GAGAN), around 1m.

Mil is +/-1m and signal is encrypted.

Saudis Want Raytheon AESA Radar on F-15s

Some interesting statistics:

The original request from Saudi Arabia was for the F-15S with a Raytheon-made AESA radar that could increase the sensor's range for detecting small targets to about 150 mi., depending on the radar cross section of the target, and almost eliminates maintenance costs. The current radar in both the F-15S and Israel's F-15I is the manually scanned APG-70, which is no longer in production. Israeli pilots say they can see large-airliner-size targets at 150 nm., but tactical-fighter-size targets only register at about 56 nm.
