S. Korea to mass-produce armed version of trainer jet starting in 2013

SEOUL, Nov. 4 (Yonhap) -- South Korea will begin mass production of an armed model of its supersonic trainer jet starting in 2013, the state procurement agency said Friday.

The Defense Acquisition Program Administration (DAPA) said it will finalize a deal within this year so that the first armed version of the T-50 trainer jet, dubbed the FA-50, will be delivered to the Air Force by August 2013. Sources said up to 60 FA-50 jets will be produced by 2016.

FA-50s are designed to fill the void left by outdated Air Force fighters, such as the A-37 and F-5. Officials say the multirole FA-50 is comparable to KF-16 aircraft.

60 FA-50 will be built between 2013 and 2016 to replace the older F-5E/F, along with 22 TA-50, among which ten are already operational.

Given the specifications, you would think that the craft would make an excellent export for smaller nations being blacklisted by America and too poor for Russian designs. i.e. Taiwan, Phillippines, and so on.

From Wikipedia, it seems the Gripen is faster and slightly lighter, at the expense of less fuel and smaller payload.

Big difference is price. The FA-50 is about $21 million vs. $40 million for the Gripen.

It depends on how much US technology is in the aircraft.

More than likely, the FA-50 would fit in as a T-38/F-5 replacement.

The problem with Phillippines is that they can't not afford newer fighters due the budget and the F/A-50 seems like a likely buy for them. The problem with Taiwan though is not the budget since Taiwan can afford high-tech military equipment fighters and destroyers and is looking to buy 4.5/5 generations multirole fighters like the Rafale and F-35. The major problem is political issues since a lot of countries have relations with China and they won't sell Taiwan any weapons due to political fall back from them. Even though U.S is major supplier of military equipment to Taiwan, but after F-16 fiasco and with certain weapon systems being delayed and or canceled due political issues from the U.S because of bettering relations with China. Theoretically, South Korea can sell Taiwan the T/F/A-50 Golden Eagle, but with South Korea is having growing relations with China, the deal is highly unlikely to come forth.

How FA-50 will compare to Gripen? It seems to be on the same weight class.

At its base form, FA-50 will be comparable to Gripen A/B in weapons integration with some edge in avionics and cockpit display because the airframe is newer. Aerodynamics is a more complex question but let's just say both are very maneuverable aircraft. The first sixty FA-50 will not yet equip JMHCS or IRST, and it will not yet integrate most foreign-made BVR weapons because of the quickness with which the planes must be built and deployed (sixty aircraft in three years) and their intended low-demand use in ROKAF (patrol, scramble jet, close air support, defensive counter-air). Some countries, like Poland, have initially requested JMHCS/AIM-9X on T-50P and the enabling of the T-50P radar's tracking mode for tracking and intercepting cruise missiles at BVR, but Poland has recently withdrawn such heavy combat requirements for T-50P due to cost concerns.


It depends on how much US technology is in the aircraft.

More than likely, the FA-50 would fit in as a T-38/F-5 replacement.

It depends at least as much on how much Korean technology is in the aircraft, and perhaps more as Korea's aerospace industry gradually evolves and becomes more technologically self-sufficient beyond its initial state of depency on foreign technologies in the 1990s and 2000s. We are going to integrate our future aircraft with a wide array of indigenous fighter weapons that will be developed without the use of US technology, and FA-50 will be the first plane to integrate them. US technology is not always necessary to improve FA-50's capabilities to that equaling F-16, though it can be useful. Korean technology has already been used in many US-led projects to improve its own air and naval weapons, like the JDAM-ER for aircraft and LOGIR for navy helicopters, and we also jointly design, develop, and manufacture F-15SE conformal weapons bay. It only makes a lot of sense that the experience from these developments find their way to Korea's current most indigenous aircraft.

The most intriguing aspect of the KF-X programme may not be the aircraft, but its new suite of weapons. DAPA has revealed plans to develop a full line of short- and medium-range air-to-air missiles, air-to-surface missiles and precision-guided munitions.

The short-range air-to-air missile will be developed from the LIG Nex1 Shin-Gung, a shoulder-fired surface-to-air missile, the administration said.

Meanwhile, DAPA has also been developing the Korea GPS guided bomb (KGGB), a 226kg (498lb) indigenous version of Boeing's joint direct attack munition.

From Wikipedia, it seems the Gripen is faster and slightly lighter, at the expense of less fuel and smaller payload.

Big difference is price. The FA-50 is about $21 million vs. $40 million for the Gripen.

If you upgrade FA-50's capability comparably to Gripen C/D, it will likely cost as much as Gripen C/D does. Some upgrades can give FA-50 a distinct advantage over Gripen C/D, like increased thrust using EJ200 or F414, both of which can be installed with minimum modifications if the customer wants a change in the engine for either industrial (Typhoon users, like Spain, will want T-50 engine commonality with Typhoon) or performance reasons (USAF). That will expectedly increase FA-50's cost. We are also able to equip FA-50 with the same RACR that will be retrofitted on our KF-16 simultaneously with FA-50's production, but this makes the airplane similarly more expensive and we ourselves do not have the budget for equipping FA-50 with AESA radar yet.


It is also bidding to provide the AE 3007 for Global Hawk unmanned aerial vehicles and the EJ200 for the T-50 Golden Eagle supersonic jet.
http://www.koreatimes.co.kr/www/news/biz/2011/10/123_96650.html


Michael Griswold, Lockheed's director of T-50 business development, said the 22,000lb thrust GE F414 would be considered.

Griswold also confirms Rolls-Royce has offered the 20,000lb thrust EJ200 engine that currently powers the twin-engine Eurofighter Typhoon. Last year, Dan Korte, president of R-R Defence Aerospace, said the EJ200 had been offered to T-X bidders.

Even if a F414 is selected for a T-X version of the T-50, Griswold said, the EJ200 may still be a re-engining option for international customers, especially existing Typhoon operators.
http://www.flightglobal.com/news/articles/lockheed-ponders-t-50-re-engining-for-t-x-programme-357148/


Selecting the RACR or SABR systems would avert this problem for an expected follow-on production phase.

How does this plane compare to the Indian Lca?

LCA and the current combat variants of T-50 both use EL/M-2032 radar, but compared to the original EL/M-2032 radar in TA-50, the FA-50 radar has its range increased by around 50% against a 1m2 RCS target, from 70km to 100km. The heaviest, latest development activity on FA-50 now appear to be concentrated around improving the radar's performance. Aside from that, all I can say is that FA-50 is a more mature design that has completed its development faster than LCA did.

Nice job. Any info on the ECM suite on this bird ?

FA-50 can use LIG Nex1's ALQ-200K ECM pod. By the way, there was a rumor that ALQ-200K was going to be equipped on Pakistan's JF-17, but that had not yet been reliably verified.

http://articles.janes.com/articles/Janes-Radar-and-Electronic-Warfare-Systems/ALQ-200K-radar-jammer-Korea-South.html

We are jointly developing with LM advanced electronic warfare suites for T-50, advanced enough to be used in dedicated electronic warfare and SIGINT on RA-50 and EA-50. The FA-50 prototypes have initially been integrated with Elisra's EW suite that include RWR and flare/chaff dispensers. The Elisra deal was $7 million and there is no more information yet that I can find on ECM equipments for FA-50.

Just a small correction. The MMR on LCA is not 2032, however it uses several components from 2032 because of failure to develop several components on time. The current radar is produced as a JV with Elta. The MMR with full indigenous content shall be AESA compatible.
http://tejas.gov.in/technology/multi_mode_radar.html

I would not comment on maturity of either, however because the primary cause of delay of Tejas, its MMR, other capabilities have been jacked up to higher standards within that time period. The EW suite gone internal, though they don't have AESA T/X modules as DARE's MiG-29 UPG EW suite has, due to space/volume concerns required for cooling of AESA. A lot of avionics have already been working on Jaguar and Su-30 for a long time, just like FA-50 will use a lot of components from KF-16, but overall both FA-50 and Tejas mk1 are very similar in terms of capabilities. I wish the designers of both best of luck for the next variants.

The contract for the first 20 FA-50 has been signed. They should be delivered by the end of 2014. Contract value is $616 million for 20 jets.


Korea Aerospace inks deal to make country’s first jet

Korea Aerospace Industries Ltd, South Korea’s only maker of planes, said it signed a 711.2 billion won ($616 million) contract to build the country’s first jet fighter for the air force.

Korea Aerospace will provide 20 FA-50 jets by the end of 2014 under a contract with the Defense Acquisition Program Administration, the Sacheon, South Korea-based company said today in an e-mailed statement. The fighter was developed based on the T-50 trainer jet, it said.

What's the specs on Korea's order? Specifically what's the engine and radar? They were considering an upgrade to the GE 414 on the engine right and possibly either the RACR or SABR radar. I hope it's still not the 2032 because Tejas, Mig-35 and even the LCA variant of the M-346 will all be having AESA radars. I also think $30 million plus on the FA-50 would be expensive if not having AESA radar.

Would be interesting to know if the cost of flight hour for both planes comes close, because in that case it could be quite attractive to some AFs to have a squadron of trainers that could be used as light F/A if necessary.

I also think $30 million plus on the FA-50 would be expensive if not having AESA radar.

ROKAF's FA-50 use improved EL/M-2032 and the same F404 used by T-50. AESA radar and EJ200/F414 are offered only for export customers. The AESA radar of FA-50 will likely be shared with the AESA radar of KF-16.

I don't think putting AESA radar on FA-50 will be that expensive. Judging from the KF-16 mid-life upgrade which cost about $10 million each, that replaces not only the radar but also other major avionics equipment, I think an AESA-equipped FA-50 will also be in the $35-40 million range. But for ROKAF buying 60 FA-50 with AESA radar would have meant that we'd be getting 30 or 40 less AESA-upgraded KF-16, and knowing that our decision was obvious.

I don't know the full cost of an AESA-upgraded F-16 yet. Probably it'll cost a bit more expensive than the refurbished Indonesian F-16s which afaik don't yet come with AESA (24 aircraft at $750 million). If an AESA FA-50 and a refurbished AESA F-16 cost the same, the Philippines - among other competing aircraft - will have to choose between the superior capabilities of the F-16 and the easier/less costly maintenance and longer service life of FA-50. The AESA-equipped M-346 will be at the lower capability range but also cheaper. Tejas looks to be the closest equal to FA-50, and Mig-35 will likely be comparable or superior to F-16. I think which aircraft the Philippines chooses for its LIFT between TA-50 and M-346 will dramatically affect its decision on the future multirole/surface attack aircraft deal.

They plan to take up a bill in Congress early 2012. I believe one of the first bills to be taken up and prioritized as the current program actually expires this month. It is to provide the equivalent of $10 billion for the next 5 years. At least that is the plan. Not sure when the bill gets approve that the proposed amount will still stand. However, a bill will be approved no matter what as they need to fund the AFP modernization program that will be expiring this month.

The current President is said to be a gun and military enthusiast and has a very high approval and trust ratings plus his party controls both House and Senate. I think it has good chances of passing and being funded well.

I don't think the M-346 is comparable to the Tejas and FA-50.

The Tejas is a fighter, but I don't know about the FA-50, is it a fighter-trainer or is it a full fledged fighter aircraft (Mach 2, long range radar, BVR missiles, heavy load, high range and agility etc) like for example the Gripen?

The fighter-trainer variant of T-50 is TA-50. TA-50 and FA-50 are largely identical but they use EL/M-2032 of two different variants and FA-50 has more advanced weapon configuration. In our air force FA-50 has been designed as a multirole fighter with configuration comparable to KF-16, and as the FA-50 program advances they'll begin to share common armaments and munitions in the same combat grouping.

The current FA-50 has seven hardpoints for weapons or external fuel tank integration. Six hardpoints are on the wing and one is on the centerline fuselage. One extra side-mounted hardpoint will be installed for a targeting pod. Current maximum payload is 10,000 pounds.

The wing has additional space for two more hardpoints (probably small ones, for missiles like AMRAAM), to compose a total of 9 hardpoints like F-16 in the future. We are pursuing an NG variant of FA-50 for the second batch to be introduced from 2016 after the current production of FA-50 wraps up. Wing-strengthening will be one of the planned upgrades, as well as improved engine and radar. A variant of EJ200 or F414 will be the most likely candidate for integration to improve payload capacity.

Eurojet has offered 60% of EJ200 engine for T-50 and KFX independent of the FX-III Eurofighter proposal. Samsung Techwin and the engine manufacturers of Indonesia and the third country will have to develop the remaining 40% of the engine.

http://www.defenseworld.net/go/defensenews.jsp?id=6193

I think it's reasonably likely that Eurojet will be chosen for KF-X even if Typhoon loses in FX-III. It can circumvent the potential problem of the plane's sale being meddled with by certain foreign countries.

Ambassador
12-29-2011, 03:17 AM
Here is a good reading material on the trend of engine development in Korea by its four major aerospace/engine developers, Samsung Techwin, KAI, ADD, and KARI. There is a CG of a KFX variant here derived from T-50 with self-developed low bypass turbofan engine, which I believe is now the Phase 3 FA-50 presented in KAI homepage.

http://books.google.co.kr/books?id=RaHvvGJdOL0C&pg=PA4&dq=Samsung+Techwin+Company&hl=ko&sa=X&ei=3xz8TryzBq2yiQegovXIAQ&ved=0CEMQ6AEwAA#v=onepage&q=Samsung%20Techwin%20Company&f=false

The four engine developers together have quite matured basic technology to begin the development of an indigenous jet engine, but it involves a myriad of technical challenges which present impractical or unaffordable money and time investment, at least for the duration of T-50 and KFX programs. EJ200 will provide a very good design basis from which the Korean engine developers can work on to significantly reduce those development risk (however, seeing that a turbofan design is regarded as more preferable for future indigenous engines, the French M88 or Japanese XF5 may also be considered).

I believe that is it.

If that was the case we could independently consult Spain only for KFX partnership.

Perhaps through the CASA-IPTN joint-venture. They already have a history of collaborating in the CN-235 program.

Come to think of it, I don't know why we have not been developing a CN-235 class light transport plane of our own yet through cooperation with countries like Indonesia. :( We already have a fair amount of understanding of a two-engine turboprop design, including a tilt-rotor one, and there's a lot of demand and market space for planes like this (not to mention that it's not really a risky development in the first place), but our government wants to immediately jump to a 90-seat design with four engines like Super Hercules. That would be a very huge jump from our one-engined KC-100 that was commercialized just earlier this year, and risky by equal proportions. I really hope the government understands well the foray it's getting into.

The Ministry of Knowledge and Economy outlined the following developmental objectives for KFX, some of which may be shared with the future FA-50 program.


◑ stealth technology shape design

Area of ​​radar RCS (Radar Cross Section) aircraft configuration design techniques to reduce. Wing Leading Edge, Trailing Edge, intakes, tail, control surfaces, door, etc. Spike Alignment technology and design techniques applied internal armed

2011 Current RCS (m˛), developed by the target level is about 1.2 m˛ in 2014, 0.5 m˛, 2015 to 2019 with the aim to develop a level of 0.1 m˛'s.


◑ absorbing metal structural design / production

Metal structures for the implementation of stealth shape design and production technology structure

Radio absorption (%) 2013 60% 2017 70% 2019 90% or more


Producing large composite structures integrated ◑

To make composite structures integrated with technology to co-cure in order to create large structures with integrated cutting-edge technology is required.

2011 currently 2,000 MM, 2013 3,000 MM, 2015 4,000 MM 2017 6,000 MM, 2019 8,000 MM


High-power compact ◑ RADAR SAR

Efficient cooling of high power transceiver modules for AESA to integrate effectively placed in a small space, and in case of failure of some transceiver module Degraded performance on the skills

TRM POWER (W) 2011 20W, 5W increments per year in 2015-2016 hadaga 40W, and 50W output from 2017 -2019 in the goal's in LA.


High-precision sensing technology ◑ RADAR SAR

When the ground to detect moving objects to remove clutter and the movement of objects over a certain speed signal processing technology to read the

Remove clutter ganseopryul (dB) in 2011, 35dB, 2013 45dB, 2014 50dB, 2015 60dB, 2017 70dB, 2019 80dB


◑ FLIR EO / IR AVR-resolution processing

From the receiver to separate the noise from the input video signal, finely ground moving objects after removal of the dynamic component, which provides the best resolution of 0.5m-class image processing technology,

Resolution (m) 2012 through Q2 2016 level of 3m 1m, 2018 0.5m, 2019 0.3m


◑ turbine blade cooling technology

Exposed to high temperatures to protect the nozzles and buckets External / Internal Cooling Technology

TIT (° C) goals by 2012, 1480 ° C to 1540 ° C from 2013 to 2019


TBC coated turbine technology ◑

Thermal shutdown temperature (° C) 2011, 100 ° C, 2014 until 130 ° C, 2015 2019 from 180 ° C forty-two

The last two objectives are a very interesting read. The desired level of IR suppression technology for whatever engine will be chosen for KFX appears unlikely to be transferred from outside the consortium, so MKE has made preliminary conclusion that it will have to be homegrown. I believe this can constitute a large part of the reason why KFX will need its engine to be partially indigenous. Along with first and second objectives that imply significant interest on the government's part to achieve tactically meaningful stealth characteristics with KFX (which includes possible installation of internal weapon bays or pods), this is a signature movement to purposefully make KFX a relatively stealthy medium-class competitor to contemporary fighters. Suppressing the engine's IR emission will be an important requirement, and if possible, supercruise capability will also be desirable to reduce reliance on afterburns.

Also, since our industry and government's current stealth designing effort as outlined by MKE is based on airframe design wing-leading edge, the KFX design will likely have to look similar to something like an up-scaled FA-50 which comes with wing-leading edge (which will conversely mean that canards will not be used). The final shape of the aircraft will be somewhat similar to Hornet or Super Hornet. We've already began advanced research on how wing leading edge, trailing edge, and RAMs on intakes, tail, control surfaces, door, etc can affect an aircraft's RCS some years ago with live application on operational jets, and we seem pretty close to our conclusion on how KFX should look like.

Flightglobal article released:



Seoul places $600m order for 20 FA-50s

South Korea has placed a $600 million order with Korea Aerospace Industries (KAI) for 20 examples of the FA-50 attack variant of the T-50 advanced jet trainer.

KAI said that under the deal it will deliver the aircraft from 2013 to 2014. Seoul could acquire a total of 60 to 150 FA-50s to replace its fleet of more than 150 Northrop F-5s.

The FA-50 is the most advanced variant of the T-50. It will have the Link 16 tactical data link, as well as an Elta Systems EL/M-2032 pulse doppler radar.

Northrop Grumman and Raytheon have said the FA-50 is a candidate for their respective active electronically scanned array (AESA) radars developed for the Lockheed Martin F-16. If the FA-50 does get an AESA radar, it is likely to be the same one chosen for the eventual F-16 radar upgrade for the US Air Force and Republic of Korea Air Force.

http://www.flightglobal.com/news/articles/seoul-places-600m-order-for-20-fa-50s-366500/

So once again I believe it's a formal consideration that FA-50 will be equipped with RACR or SABR if there are countries who want to buy it with an AESA radar. Alternatively there is another small Korean AESA radar with 590mm aperture size and 536 T/R modules under development in Korea with FA-50 as the primary testbed, but it will take some time for the program to complete, probably not before T-50 Phase III.

$30 million for a non-AESA equipped FA-50 is on the spot. The approx. $30.8 million previous quote was expensive for an FA-50 equipped with only a relatively affordable radar like the Elta 2032. And I think $31-$31.5 million for an FA-50 equipped with an entry-level AESA is about right as well.

Even the LCA version of the M-346 is being planned to have a SELEX Galileo 500E radar, so I think the FA-50 really do need to have an AESA radar option for foreign customers to compete for Int'l orders.

Alenia Aermacchi is willing to launch the development of a dual (training and combat) capable version of the M-346 Master advanced trainer/LIFT by the beginning of next year. The new version will feature an enhanced avionics and mission systems package including Selex Galileo's active electronically scanned array radar, the Selex Elsag communications suite based on secure radios and data Link 16, a helmet-mounted display and an electronic warfare suite based on Elettronica's RWR, and including a chaff and flare dispensing system. The dual-role M-346 will exploit the aircraft's capability to carry on nine stations an external 3,000kg load including air-to-air and air-to-ground missile and gun pods, such as new air-launched MBDA Marte Mk2/S-A anti-ship and Brimstone air-to-ground missiles, in addition to auxiliary fuel and targeting/recce/EW/training pods. The new version could be ready for production in 18-24 months from launch date, according to Alenia Aermacchi.

I've now found the most reliable source to answer this question:


I've seen renders of the FA-50 with an insane weapons load, what's its realistic weapons load? Comparable to other light fighters (Jas-39, Jf-17, Tejas)?

http://www.dodaam.com/eng/sub_0203_1_3.php

The SMC is being developed for use with 9 weapon stations, 4 of which is for A2A and 5 is for A2G. Two of the A2A weapon stations can be located at the wings in dual missile rail configuration similar to F-16 (of course this is just my educated guess at the moment; see stations 7/7A and 3/3A in the following F-16 diagram), while the other two will be at the wing-tips. The rest will be used for ground-attack weapons. The system overall is described to be 'supportable for F-16's operational stores', so I believe it can be improvised to equip the same armament as F-16 as needed, for as long as the airframe can bear and spare the weight and size of the armament, and the radar supports the weapons' search-and-track requirement. Using RACR or SABR would basically mean being able to use virtually every light to medium weapon that F-16 is presently known to use.

172774

The new HUD that is being developed along with it is scheduled to be complete in 2012.2.29, so I believe the SMC will also be completed around that time and safely be used on FA-50. The HUD will feature improved weapon-aiming information display over previous T-50 and TA-50 variants, among others.

Samsung Thales (STC) formally announced the development an AESA radar for FA-50 to compete with LIG Nex1's AESA radar model.

In retrospect I think the lessons taught by LM's meddling with T-50's fighter transformation was highly useful to our defense industry in the long-term in that it compelled it to strive to become as self-sufficient as practically possible in fighter technology. Without the restriction on the use of foreign technology on FA-50 imposed by LM, our defense industry would not have worked harder to produce parallel domestic technology on its own to adapt to and overcome the imposition (if we were able to integrate the Selex 500E AESA radar on FA-50, this domestic FA-50 AESA radar project likely would not have taken off for a looong time). It explains the rigorous efforts by the Korean defense industry to indigenize as much avionics technology of FA-50 as possible so that the plane can operate with negligible foreign technology that LM may outrage at. A separate core avionics development project with the same objective of achieving technological self-sufficiency is being conducted by another consortium of Korean companies and defense development agencies through state-funded budget (the DoDaaM Systems fire control system in the above post is a part of this project):

Government Funded Project to localize Core avionics systems and software. The mission software being called Operational Flight Program was developed using real-time Java language. This presentation shows how we came to choose Java and what we’ve done in the early stages of the development to adapt to Java.

http://www.slideshare.net/keugbang/t-50-avionics-embedded-software-development-using-java

Our export variant T-50I for Indonesia is already able to use many of the above-mentioned domestic avionics technology that have been developed intentionally without Lockheed Martin's involvement. A lot of efforts have been poured to facilitate increasingly foreign-independent operation in the further development and manufacturing of T-50 in the past fifteen years. The turn-out in employment is remarkable (though not solely from T-50 work, even while it's KAI's single biggest aircraft program at present) and KAI envisions to quadruple its revenue in the next eight years:

WOW! And they are going without a partner?

Thales is a natural partner of Samsung Thales. However the IP licensing share of a particular Samsung Thales product works on 50-50 ratio only if both the Korean department and the European department agree to fund the same amount of budget from each side on the product's R&D. This is usually the case in self-funded developments, but not necessarily when it develops the technology through paid contract from an external customer like, for example, the Korean government, a quite common occurrence. If the Korean defense industry & Co are the majority fundraisers for the AESA radar R&D then the AESA radar will mostly be tagged as 'Korean technology', with the majority Korean share of the royalty fees for the technology's use. The high local share of the R&D is also necessitated to deter LM's objection at the use of European technology as the Selex 500E case had been; European involvement will have to be discouraged as much as possible to make the AESA radar technology localization program meaningful.

9 hardpoints ? What's the proposed payload ? Also is the nose cone being made larger from the current 590 mm ?

DoDaaM Systems' FA-50 fire control system is being developed to handle 9 weapon hardpoints, which are fully compatible with F-16's operational stores. KAI needs to make a separate improvement to the wings to accommodate the heavier armaments (right now the first-batch FA-50 prototype pictures still show only 7 hardpoints activated), and there should be suitable radars for the exceptional standoff weapons. DefenseIndustryDaily says integrating AMRAAM and anti-ship missiles is definitely possible with the EL/M-2032 radar already, but better radars wouldn't hurt. The maximum payload weight will likely be limited to 4.5 tons while it FA-50 still uses the 17,700 lb-thrust F404 engine; engine improvement will be important to increasing that capacity. I don't know yet about the nose cone though.

If there is an example of KF-16 having already used a better or comparable system to Exocet, yes. Harpoon qualifies as such a system.

FA-50's current maximum payload is 4.5 tons. If we want to improve it further we'll likely need to improve the engine.


The FA-50 also has a radar warning recover and a night vision imaging system. It is capable of carrying 4,500kg (9,920lb) of weapons, including the Boeing Joint Direct Attack Munition and Textron CBU-97 Sensor Fused Weapon. Like the TA-50, it also has a 20mm cannon and can carry air-to-air missiles.

Gazmin said the planned acquisition is under review since the fighter jets are being phased out from the US Air Force inventory.
The US fighter jets might have limited flying hours left, he pointed out.


“Before we can have these fighter jets, we must also send our pilots for training. So it’s better to acquire first the so-called lead fighter jets,” Gazmin said.

The defense department also plans to acquire fighter jets from South Korea.

LCA and the current combat variants of T-50 both use EL/M-2032 radar, but compared to the original EL/M-2032 radar in TA-50, the FA-50 radar has its range increased by around 50% against a 1m2 RCS target, from 70km to 100km. The heaviest, latest development activity on FA-50 now appear to be concentrated around improving the radar's performance. Aside from that, all I can say is that FA-50 is a more mature design that has completed its development faster than LCA did.

http://img812.imageshack.us/img812/5811/130742343919.jpg

Ambassador, hi, I just want to check with you, can you provide the link for the source of the data above, the one that says, "... EL/M-2032 radar in TA-50, the FA-50 radar has its range increased by around 50% against a 1m2 RCS target, from 70km to 100km ..."?

Is it supposed to be from the drawings? Just a little confused because the drawing seems to show a MIG-23, so to me it could mean detection range for the MIG-23's RCS, which I don't know at the moment.

Incidentally, the only data with a source link to it for the EL/M-2032 radar was from this site: http://www.enemyforces.net/aircraft/mig21 .htm, which says the detection range for the EL/M-2032 is only 46km head on for an aircraft with 5m^2 RCS.

Sorry, I am just trying to figure out something, hence I wanted to get data and sources. Thanks.

Ambassador
07-24-2013, 11:12 PM
I cannot recover the original source for either of them anymore (one of them is MKE's program data on KF-X). But I was planning to update them anyway.

There are other sources and more information for the TA-50/FA-50's radar range. The TA-50's radar range depends on the radar's search mode: search-only mode and search-and-track mode. In search-only mode, detection is possible at a range of 60km. In search-and-track mode, this range is reduced to 40km against air-to-air targets. So you can assume that the TA-50 radar has more or less similar performance as the Bison EL/M-2032. The TA-50 radar has a practical A2A engagement capability of around 40km against contemporary air targets.


To use EL/M-2032 radar to detect enemy aircraft 60 km away, outside the 40 km distance from enemy air-to-air missiles can be launched.

However, I also think the version of EL/M-2032 used for the Bison upgrade is one of the radar's older versions, and thus there will be other generations of the radar that are more capable than that. In the source you brought, the Bison EL/M-2032 is described to be incapable of a number of track-while-scan capabilities, like prioritizing or simultaneously engaging multiple targets. We know this is not true for all EL/M-2032 variants, because the EL/M-2032 is capable of performing both in other aircraft.

I will update TA/FA-50's technical specifications as new information are released. Companies like LIG Nex1 continue to develop improved technologies for military aircraft, like the 'smart skin antenna' (but more commmonly referred to as conformal radar array) typically found on the sensor fusion package of advanced fighters. RCS- and drag-reduction features indicate that this mutifunctional conformal radar being developed by LIG Nex1 is for combat aircraft as well.


Structural design and development of multiband aero-vehicle smart skin antenna

Published online before print July 3, 2013, doi: 10.1177/1045389X13493358 Journal of Intelligent Material Systems and Structures July 3, 2013 1045389X13493358

The load-bearing antenna approach for state-of-the-art aero-vehicle structure has been made for military aircraft in recent studies. This study presents the structural design and development of multiband aero-vehicle smart skin antenna which has been developed as a simplified structured load-bearing antenna panel compared with recent studies for aircraft. A multifunctional concept of aircraft structure combines structural and electrical functions to single structural component. The structural function of multiband aero-vehicle smart skin antenna is load-bearing member of aircraft, and its electrical function is antenna for communication and navigation of aircraft. The radar cross section and drag reduction could be achieved by using sandwich structure and composite material. Through sequential design and development process, multiband aero-vehicle smart skin antenna successfully demonstrated the design, fabrication, and structural integrity of a load-bearing multifunction antenna component subjected to flight load conditions. This study concentrated on the computational analysis using finite element to validate the structural design of multiband aero-vehicle smart skin antenna structure. In addition, structural test results were briefly introduced to compare with the analysis results. The prototype of multiband aero-vehicle smart skin antenna was fabricated and tested for the verification of each analysis within the desirable tolerance.

Iraq has today ordered 24 T50IQ a specialised and upgraded version of the FA50. the deal is for $1.1Bn for the aircraft and $1Bn for training, support, weapons for 20 years.

At $45M a pop flyaway cost, the Iraqis will presumably get an AESA radar (they are certainly not buying Elta 2032), uprated engine, HMS and other goodies.

deliveries 2015-2016
