Greece upgrades 85 F-16 to the Viper level, partially financed by the USA !


Greece finally has given the green light for the F-16 Upgrade program to start!

Greece on 30th of April 2018 singed the Letter of Acceptance (LOA) for the Viper Upgrade program, after a decision was made during the Saturday’s (28 April) last-minute KYSEA (Goverment Council on Defense and Foreign Policy). It took almost 6 months of negotiations between the Greek Goverment and the USAF (which is the prime guarantor for the progress and supervision of the Upgrade Program) until a contract was signed to upgrade 85 of the 154 F-16 to the latest Block 70/72 Viper variant. Total cost of the program is around 1.45 billion $.

Specifically a single F-16 Block 50+ (which previously has been used as a prototype for the latest Peace Xenia III program) along with 30 F-16 Block  52+ Advanced and 54 F-16 Block 52+ will be upgraded during a 10 year period. In August the first Greek F-16 will arrive in the United States of America to become the testbed aircraft. During a 2 year period the first aircraft will conduct operational tests to verify the functionality of all its sub-systems. Approximately 12 aircraft per year will be delivered by the Hellenic Aviation Industry (HAI) between 2021-2028.

The main modifications include:

-APG-83 SABR AESA radar

-new Link 16 MIDS-JTRS (this makes redundant 30 older Link 16 MIDS which are currently used by the Block 52+ Advanced variant, possibly reused for the Block 50 models)

-new central display CPD HD 6×8 inches

-new IFF APX-126 CIT with Mode 5 and Mode S functionality

-new mission computer MMC 7000AH

-Full access to all current Weapons Inventory used by Hellenic Airforce (AGM-154C JSOW, GBU-31/38 JDAM, GBU-50 EGBU (EP-II), GBU-16 PW II, AFDS)

-one new flight simulator, while upgrading two existing


The new radar will give better detection capabilities and high-jam resistance compared to the mechanically scanned APG-68 v9

While the Greek program will cost in total around 1.5 $ dollars, including spare parts for a long period, training and integration of the new systems, an undefined yet amount of it will be paid by the FOREIGN MILITARY FINANCING PROGRAM and specifically the 460 million dollars OCO/GWOT which is under the «Countering Russian Influence» section

You can find the proposal funding by the American Congress in the link below:


While this fund is included in the 2019 Fiscal Year (maximum 460 million $ dollars), no payment can be done before by the American Government approves the 2019 budget, so the Greek Goverment will send the following month the first installment of the payments (around 223 million $). In addition the American side agreed on a longer and more fair payment period than previously proposed.

Too late, too little?

While the upgrade program is a positive outcome after a long period of inaction, the Hellenic Airforce chose to upgrade only its latest delivered aircraft (85) leaving almost 70 older aircraft at current state.

This was done due to limited resources and is acceptable.

A possible second low-cost upgrade program re-using older avionics removed by the upgraded Vipers could bring them either to the Block 52 + Advanced version (link 16, MMC 7000 and APG-68 v9 but only for 30 of them) or to the Block 52+ level (MMC 5000 and APG-68 v9 with no Link-16 Mids).

The new Viper model will have the following new capabilities:

-network centric capabilities due to the new Link-16 and MMC 7000AH (improved model)

-longer detection range due to the new APG-83 AESA

-wider scan  ( APG-83 AESA)

-high jam resistant

-Maritime modes

-better IFF capabilities


The main goal of the Viper  program is to provide a low-cost interim solution until the Hellenic Airforce (HAF) have the financial resources to obtain 4th/5th Generation Aircraft. The total period of the program is 10 years which could not categorise it as interim solution but probably as a long-term solution . During that time (until 2028) the main adversary which is the TuAF (Turkish Airforce) will probably receive 60-80 F-35 A/B, having operational 40-60 of them. The Turkish Airforce (TuAF) has already 200 F-16s CCIP (APG-68 v9 and link 16) and is also obtaining four EW Jamming aircraft under the «Shadow» project.

-The APG-83 AESA radar can give the edge against the turkish F-16 CCIP but it could not be a threat against the stealth F-35A and its Low probability of Intercept APG-81 AESA radar. The turksih F-35s will see first and probably guide (sharing through link 16, same mission will also have the longer range E-737 T Wedgetail AEW & C) the numerically superior turkish F-16 CCIP which will face the Greek Vipers.

Even if it was early identified not only by our site Defencegreece but also by the former Lieutenant General Theodoros Giannitsopoulos ( check Upgrading the F-16s: A Former Lt General SOS and also the Lt Colonel K.Zhkidis (Fotis Pantazoglou interviewing Lt Colonel K.Zhkidis) that the IRST systems will play a significant role in future air-to-air combat, no option has been included for installing a nose-mounted IRST like the Skyward G-IRST (high cost, maximum performance) or at least a Legion Pod (IRST 21 sensor) carried externally (drawback is the bigger drag but has lower cost). Without an IRST system the probability of kill of an AMRAAM missile (X-band seeker) against a turkish F-35 (specifically designed to have the smallest RCS in the X-band) is small to none ( terminal MPRF mode of the seeker is activated approximately 7.5nm from the target). The APG-68 v9 radar compared with the active radar seeker of the Amraam while  having a much greater power output, Antenna Gain and singal processing  can possible detect an F-35 at only 8-9 nm .

The next alternative weapon of choice for the Greek F-16 Viper is the AIM-2000 (IRIS-T) missile which has a maximum range of 25 km (operational range is lower) and uses heat-seeking terminal guidance. The F-35 in that case has one of the bigger heat signatures in the Aegean Theater. Problem in that case is that except some opportunity shots, the turkish F-35s might be able to engage beforehand with its BVR (AIM-120C/D) missiles.

The interesting part is that the Lockheed Martin has already integrated the french  Magic 2 missiles in the Block 70/72 variant to cover the requirements of the Indian Airforce (F-16 Viper is offered to India and is a contestant for the Single-Engine Fighter Competition Make-In-India initiative ). A french missile like Magic 2 integrated in the avionics of an American aircraft is not technically impossible. And this was done for the India contest.


Skyward IRST would be a great addition to the Viper but the complexity of the project would be increased

Magic 2 missile wouldn’t provide any real advantage against an F-35. But the question is would a MICA-IR be a candidate choice? The MICA-IR is a very agile missile (capable up to 60 g maneuvers) and has a maximum range of 50 km. It could make the difference when used in BVR combat because its passive IR seeker doesn’t alert the target aircraft in the terminal phase of the engagement and also the F-35 has a rather visible heat signature. Also under the MICA-NG program, a new future booster will be used which will give a +50% range. Equipping the F-16s with a heat-seeking BVR missile will also require the installation of an IRST system providing tracking data. Also it is rumoured that the UAE’s F-16 Block 60 E/F are also using the MICA IR/RF missiles.

-As for the air-ground and air-surface weapons, nor the PGK SDB-II neither the AGM-158 JASSM cruise missile will be integrated. While the HAF creates a 85 strong core of advanced network-centric F-16 Vipers, it doesn’t upgrade their weapons lethality.

Also around 2025, most of the 18 Mirage 2000 EGM/BGM which now form a TASMO (anti-ship) squadron will need to be retired. Existing AM-39 Exocets are not compatible with the F-16s. So probably the HAF while retiring these aircraft will retire its TASMO capability or some F-16s need to take the TASMO role (other missiles need to be procured like the norwegian NSM). Under the current signed Viper Upgrade program, no such option has been included.

In conclusion, the core of the HAF for the following decades will still remain the venerable F-16 in its more advanced version (Block 72) with new AESA radar and advanced avionics. This program alone reduces the future technological gap but not at that point that the balance is restored  between HAF and TuAF.

PS. The funding (max 460 million dollars) by the American Congress proposal under the «Confronting Russian Influence» program would make someone very cautious. No one give you a free gif. There is an old greek saying «Beware of  Danaous (ancient greek tribe) bearing  gifts»…

  1. …and Nikos Xylouris sang «mpikan stin poli i ehthri, meirazan dora (bank loans) i ehthri…».

    Cultural geographer David Harvey did a research on how slavery became a phenomenon and what he showed was that on the battlefield, when someone begged for their life they gave their servitude for as long as they live to have their lives spared. In short, they became indebted.

    Hence debt is slavery: and freedom is primarily a matter of economy; a set of local+regional+domestic+exoteric currencies. Read about the Miracle of Wörgl in 1932-1934 which in 14 months lowered its unemployment level from 20 to 10 %. How? By keeping a bigger portion of the money within the city (local/regional/national) borders.
    * (MUST READ)

    By September 1933 Vienna ordered the army to invade Wörgl (!) if they did not end their currency. Why? Because over 100 cities in Austria wanted to create their own local currencies: they would have KILLED THE BANKS.

    Its first modern equivalent was the Chiemgauer in 2003 from the region of Chiemgau in Germany. Copy the method, apply in your city, and watch the Rothchilds croak: a €7.61 billion turnover in 2015 – wake up, imagine the turnover in € from 11 million users!

    As for IFF and other western electronics, USSOCOM stated that the Russians are «succeeding in disrupting or systematically disabling the US systems in Syria making it impossible for the Pentagon to survey the combat zone. During the tripartite attack of 14 April, the Russian army succeeded in hacking the GPS transmissions with the effect that some missiles were diverted. Worse still, the systems for friend/enemy recognition have stopped working.»

    Conclusion, the spent $1.5 will only be good for Hollywood. Create your new currencies (electronic at first and as soon as possible make them physical and tied to real value, not FIAT €) and then you soon will have both autonomy – anexartisia dammit – and money for Pantsir’s, Bastion’s and S-400’s.

  2. The primary issues are: $ vs T(money versus time) Based on lengthy experience with aerospace industry as programs get stretched the 💰 dwindles and new problems arise from political venues.

    The upgrade is needed but the program should be a four year plan with a maximun five year plan and not a ten year plan. In these monies there should have been made allowance for inclusion of IRST systems. IRST inclusion could be an indigenous Hellenic program but access to the algorithms is required to link properly the systems. Additionally, an indigenous program similar to an advanced «have glass program» should be started to reduce the RCS of the F-16’s and the Mirage aircraft. A hypothetical 25% decrease in RCS will go a long way to also help against present and future detection by non friendlies. This assumes also treatment technologies of the inlet and exhaust systems as well as the cockpits of both aircraft. All the so called 🎄 trees arrangements will have to give way to steatlh capsules that will contain the nesessary missiles bombs etc.

    Therefore the idea is to stretch and increase as much as possible the current capability with Link 16 countermeasures etc as to be able to include ability to control UAV’s that should come down the pipe line.

    The work done at government facilities should be done at cost value i.e no profit with the understanding that the technologies developed can be used for exports.

    In fact there additional things that can be done to lower the RCS of 4th generation aircraft details of which cannot be presented on the web and go beyond simply applying a second rate RAM coating. It is known that shaping is a great factor in stealth technology masking of inlet ducts and fan / compressor, cockpit and exhaust nozzle treatments etc. An estimated 30% -40% improvement in RCS reduction can be expected from a combination of these technologies. Furthermore plasma stealth is another system architecture that can be implemented further reducing the the RCS. The issue becomes whether one is allowed to implement any and all of these technologies even at a research level thus ensuring a non existent funding. For example the F-16 inlet was modified and the ‘knee bump’ was tested it was proven prior to the implementation to the F-35. Therefore the technology exists.etc….etc…

    Additionally, a systematic approach to RCS detection and identification can be developed whereby several systems having been examined and their RCS determined via proper benchmarking of the RCS prediction code(s) for several aircraft. Thereafter a probability distribution curve is applied mathematically to the signal (s) and the identification problem is bounded for each system be it an F-16 Mirage Rafale F35 UAV AA Missile etc etc. This signal (s) is also compared to other known signals of the threat IR, Lasing, etc etc and very quickly statistically the problem is bounded. Thus, Algorithms can be written so that they can also be hardcore imprints on chip technologies to effect a very quick friend or foe type of ID. To this end an independent signal processing system can be developed and be tested and be put into use following a systematic step by step approach having benchmarks results and statistical processes algorithms and electronic component manufacturing capability. Again this type of program management requires first setting up the proper program management with bottoms up and top down processes established that outline each step and the stakeholders with costs and timelines. The program will have identified sub component testing and system testing and the linking process to existing systems be it ground or airborne systems. COTS could be used to simplify the process and cost. The goal would be to develop independent technologies for RCS ‘sniffing’ if it would be allowed thus again this is determined by funding allowances which are minimal or non existent in Ellas.
