In part 2 we continue to look at the Northrop F-20A Tigershark and how its story intertwines with other aircraft programs of the 1980s.

 

 

Another F-20 is flown

The second Pre-production F-20 (82-0063 / GI1001) was flown in August 1983. This configuration included a bigger radome, enlarged canopy, and an up-rated 17,000 lb thrust F404 engine. (Note: The first pre-production jet mentioned in part 1 (82-0062) also received the 17,000 lb thrust engine in 1983.)

Also note: “Pre-production” means that Northrop was not going through a Prototype or Full Scale Development (FSD) phase so these aircraft were actually intended to be sold with the F-20 upgrades and changes.

Let’s get some people on board to really help sell it (F-20 Tigershark Vs F-15)

You remember the Light Weight Fighter Mafia right – well they had mostly since left the Pentagon and had reformed as the err “Reformers” (or “Critics” to the USAF), which included John Boyd, Ex USAF Col Everest Riccioni, Pierre Sprey, Chuck Spinney and James Fallows.

James Fallows was Washington editor for The Atlantic Monthly.( Described as an anti-military liberal journalist) Fallows had cottoned onto the Reformers in 1979 when researching ideas on how to cut military budgets and had interviewed John Boyd who was still smarting over what was done to the F-16. Fallows was able to gain publicity for the Reformers and their ideas, for example through the best-selling book National Defense in 1981.

The Reformers had jumped on the AIMVAL/ACEVAL (Air Intercept Missile Evaluation / Air Combat Evaluation) results in the late 1970s where Red force F-5s had faced off against a blue force of F-15 and F-14s, and the book National Defense was the perfect platform to spin the results. The book took choice cuts from the results carefully omitting information that didn’t fit their agenda and the press went for it, with the Chicago Tribune printing that the F-15 had been “fought to all but a draw” by the F-5 and CBS calling the F-15 a “turkey”.

In National Defense reformer Everest Riccioni claimed F-15s couldn’t fly many sorties and so the Air Force actually had a “Phantom fleet”. He then claimed the Air Force could buy 1000 advanced F-5s (The F-20) for the cost of 250 F-15s and generate 10 times more sorties in wartime (2500 v 250). Did I mention that Northrop had hired Everest Riccioni and Pierre Sprey at the time and Riccioni was working on the F-20 program.

In reality what had happened in AIMVAL/ACEVAL was that tactics used were not entirely realistic and a lot of it was skewed in favour of the F-5. Despite this the F-15 still had a 2.5 Kill ratio in favour and the AIM-7 (another Reformers target) was responsible of the majority of the simulated kills.

From the USAF point of view neither Pierre Sprey or Everest Riccioni had any credibility compared to John Boyd (who had taken a back seat at this stage) and the scraping nails account of this episode suggests this did more harm than good to the F-20 program regarding US support.

F-15C - Can you say “it’s a Turkey” in a Pierre Sprey accent? (Airliners.net)

 

 

 

 

What else could have upset the USAF

Although a typical sales tactic, Northrop had no real data to back up any claims they were making for the F-20 such as cost, reliability and sortie rate. For example, as RAND point out………. Northrop claims of reliability on the F-20 were pretty much irrelevant. Only 1500 flights in a “test” environment with hand-picked engineers cannot be compared to years of “operational” experience the F-16 had around the world maintained by guys with varied experience in different environments.

True cost and sortie rate could never be known as none ever went operational. Some of Northrop’s claims also seemed to stay the same despite airframe and avionics changes that would increase cost.

 

 

 

F-20 goes to Top Gun

Back in the mid-1970s the USAF were allocated F-5s that never made it to South Vietnam that were wanted because they were very similar in performance and some other aspects to the MiG-21 and so were perfect to use as aggressors at Red Flag.

Naturally in 1984 when the US Navy wanted a MiG-29 simulator / aggressor for Top Gun, Northrop seeing a way in offered the F-20A at a low price with its promise of lower operating costs. Senator Pete Wilson had managed to get money through congress in the hope the F-20 was selected.  

General Dynamics also offered the F-16N (F-16C Block 30 with gun replaced by ballast) for a very low £11m each which was the same unit price as the F-20.  The USN went with the F-16 which they believed to be a better simulator for 4th Gen threats…and it probably was being a bit larger with superior performance, also high-tech avionics were not required, in fact they stuck in the basic APG-66 radar from the A model.

The USN literally got steal of the century on unit cost here…………. or they would have done if someone at the Navy hadn’t specified titanium wing attachment brackets without testing them (another story).

Another F-20A flies

The third pre-production F-20 (82-0064 / GI1002) first flew on May 12 1984 and was similar to 82-0063 / GI1001 in configuration it seems.

Tragedy befalls Northrop and the program

On the 10th October 1984 the first pre-production F-20 (82-0062) crashed at Suwon Air Base in Korea killing pilot Darrell Cornell.

Cornell had apparently succumbed to G-LOC after a 9G pull up as part of practicing an established demonstration routine with the aircraft appearing unresponsive after the maneuver.

 

 

 

The Northrop F-18L and McAir

All this time Northrop had been having a handbag face slapping argument with McDonnell Douglas (McAir). In October 1979, Northrop filled a $700 million antitrust suit against McAir.

Northrop had developed the YF-17 for the Light Weight Fighter (LWF) competition in 1974 and this was later developed into the FA-18 carrier-based fighter under some kind of teaming agreement. Under this agreement McAir as prime contractor would build 60% of the carrier capable FA-18 and Northrop would build 40%. For the land-based F-18L Northrop were prime contractor building 60% and McAir building 40%.

The Northrop F-18L was what might have been if the YF-17 had won in 74. Without all the extra weight needed for carrier ops and a totally different 9G structure it was over 2500 lbs lighter with a top end of M2.0 and was initially specified with a hard wing losing 3000 lbs of fuel reducing its range.

Northrop basically had accused McAir of trying to monopolize the business and basically interfering with the F-18Ls chances of success in the export market by launching active sales efforts for the FA-18 to potential customers when they showed interest in the F-18L. Another suit also claimed McAir was unfairly using Northrop technology from the F-18L to sell its own FA-18.

McAir then counter-sued against Northrop, claiming that the Northrop F-20 avionics had been taken from the McAir FA-18…….

 

The suit was finally settled by April 1985……. which meant McDonnell Douglas would pay Northrop $50 million and become the prime/sole contractor for all FA-18s including export sales, and thus the F-18L was never heard from again…………..

F-16C v F-20A merge head on

In April 1985 to try and finally get some sales from the US Government, Northrop offered 396 F-20s to replace current F-16C production at a fixed price of $15 million, undercutting the F-16C fixed price of $18 million. General Dynamics hit back with a 720-plane proposal for stripped down F-16s at $13.5 million each with cheaper avionics. These were apparently jokingly referred to as the “F-16C-minus”. This clearly came to nothing.

F-20 #3 again (Northrop Grumman)

 

 

Another Tragedy

On the 14th May 1985 at Goose Bay, Canada the second pre-production F-20 (82-0063 / GI1001) crashed in a similar manner to the first killing Dave Barnes. Barnes was incapacitated during or after a 9G pull up as part of the demonstration being practised for the Paris air show. With no flight recorder on board the enquiry attributed this again to G-LOC and possibly a result of reduced G tolerance after flying four high G demonstration flights that day.

 

 

 

The Air Defense Fighter (ADF) competition

In 1986 the US Air Force (as ordered by Congress) held a competition for 270 mainland Interceptors for the defense of the Continental US. Both the F-20 and F-16 were contenders, and good point defense fighters despite the reservations of some. Sadly, again the F-20 was not favoured for a few reasons:

·

  • The F-20 was not in production so the costs couldn’t be guaranteed
  • The cost to operate and maintain it would be higher than Northrop had claimed.

 

In the end neither the General Dynamics or the Northrop proposal were selected by the Air Force, instead it was decided to take 270 F-16A Block 15s in service from the Air National Guard (ANG) and modify them to an ADF and OCU (Operational Capability Upgrade) standard, with:

  • A higher thrust F100-PW-220 engine
  • Capability to use bigger 600 US Gal drop tanks
  • An Advanced IFF interrogator
  • An upgraded APG-66 (V) 1 radar with increased range, small target capability and the capability to fire AIM-120 and AIM-7.

F-16 A Air Defense Fighters (USAF)

 

 

 

Making the F-20 better (The fourth Pre-production jet)

Interestingly by the 1986 ADF competition there had been changes to the F-20 to increase range and deal with carriage of AIM-7s with proposals to:

  • Increase internal fuel to 5050 lbs by replacing the fuselage bladder with integral fuel tanks.
  • Increase external drop tank size.
  • Increase thrust of the F404 to 18000 lbs to offset the extra weight and drag.
  • New Electromagnetic Maneuvering flaps.
  • Fly By Wire control system with backup Hydromechanical controls (similar to FA-18)

Northrop & GE were also working on an upgraded APG-67 radar with enhanced range. This was proposed by putting a bigger antenna on it and moving it back in the nose. Luckily, they also intended to replace the obsolete M39s with a single modern gun to make some room for the radar move. This is said to have been planned for the fourth Pre-Production aircraft (82-0065/ GI1003) but was only 25% compete when cancelled. This remained a paper airplane but nonetheless a valiant effort to reduce some of the performance deficiencies.

Of course, the glaring problem here is that by making these changes the cost and complexity increases, reducing its advertised selling points and ending up with a jet that offers nothing significant over the F-16 and FA-18…………and unfortunately the US was still not interested in buying it.

 

 

The end

Northrop closed the F-20 program at the end of 1986 at the cost of around $1.2 billion……… it just was not meant to be with everything against it. However, despite the loss Northrop were still doing okay out of the FA-18, ATF (YF-23) and B-2 programs at that time. No conciliation to them but perhaps an example of how competition can sometimes benefit US services by keeping cost down.

Thanks a lot for both reports. F-20 would have been a great airplane for export, but the F-16 was offered so cheap that it simply had no place anymore.

Are there any concept images of how the fourth larger prototype would have looked like? It's safe to assume it would have been similar to how the F-16 and F-2 are very similar except the wings are larger (along other things), right?

Gaaaagghh............really sorry Toni what a screw up...how did I not spot that!!

I have left in that section from an initial draft. I did read that wing area would be increased but it didn't tie in with the better sources and think it might have been confused with another source that states adding the new maneuver flaps may have increased effective wing area by 10% in some situations.

I see. Don't worry, we all make mistakes!

So, then the wing would have been very similar if not the same as the standard one except for the flaps. I still wonder how amazing the fourth F-20 would have been to fly if the other three were already as good as some people say.

If I remember correctly, from his auto biography, Chuck Yeager loved the F-20, and is even seen in a commercial with the F-20 in the background (

It would be really cool if some one with SKILLZ would finish out and polish the F-20 for SF/WOX 1 series

      View File Hellenic Air Force F-5A Volume I
      July 2020
      ===============
      Hellenic Air Force F-5A Freedom Fighter Volume I VERSION 1.0
      ------------------------------------------------------------
      F-5A variants included in the Package:
      HAF F-5A standard version (1965 - 1974)
      HAF F-5A with Martin Baker IRQ-7a ejection seat  (1975 - 1999)
      HAF Rf-5A reconnaissance variant with 4 K-92a cameras
      We are proud to present the F-5A HAF Volume I, the first of many to come, focusing on one of the most enduring American military aircraft designs ever produced during the Cold War period. This first Volume depicts the following Hellenic Air Force variants; the HAF F-5A standard, the HAF F-5A with the Martin Baker IRQ-7a ejection seat, and the HAF RF-5A reconnaissance variant. It has been our goal to provide to the simmer a highly detailed model and texture base which preserve the beautiful lines of this aircraft; and to engineer flight files and a cockpit/gauge file-set that are authentic and add to the immersion of the flying experience within the Strike Fighters 2 series.

       
      INSTALLATION INSTRUCTIONS:
      --------------------------
      1. Copy the contents of the "To Mods Folder(S)" to your SF2 Mod directory.
      Allow directory merging and overwrites, provided the overwrites pertain to "fake pilot" entries, as well as weapons made by ravenclaw_007, which are included in this and many other releases.
      2. Add the entries of "ADD_TO_SOUNDLIST.txt" to your SOUNDLIST.INI (located in the "user\Saved Games\ThirdWire\StrikeFighters2\Flight" folder).If one does not exist, then you will need to extract it using the 3rdWire CAT extract utility.  You are simply required to substitute the "XXX"s  with the next sequential number in the sound file section of the file.
       
        NOTE    1:
      ------------
      Both Regular and Higher resolution cockpit textures are included in their own distinct folders in the package.
      The user may alternate between the two by "commenting out"
      the relevant line in the F-5A_STANDARD_COCKPIT.ini

      [CockpitData]
      //Directory=cockpit      
      Directory=cockpit_Lo-Fi    <---This is the default

      In order to "activate" the higher resolution textures
      you would decomment the previous line and comment out
      the next line, thus:

      [CockpitData]
      Directory=cockpit          <---This is now Hi-Res
      //Directory=cockpit_Lo-Fi    

        NOTE    2:
      ------------
      Another frame-rate friendly option for those with older hardware is to use the Next level of Detail Model as the primary external model. This simply involves changing the first line in the F-5A_HAF.ini  from this..
      [LOD001]
      Filename=F-5A_STANDARD.LOD
      to this..
      [LOD001]
      Filename=F-5A_STANDARD_002.LOD
      Much effort was made to provide those with lower end systems an alternative lower poly-model to be able to enjoy the F-5a,  so please take advantage of this _002.LOD model should you experience frame-rate issues.  While not as "rounded" as the Higher poly version, it is nonetheless just as detailed and extensive.
       NOTE    3:
      ------------
      For those who may find loading times excessive, the .jpg files in the texture folders can be reduced to 50% of their size without sacrificing too much surface detail.

      ****************************************************************
      FEATURES:
      * Three model set including the HAF F-5A standard version (1965 - 1974), the  HAF F-5A with Martin Baker IRQ-7a ejection seat  (1975 - 1999), and the  HAF RF-5A reconnaissance variant with 4 K-92a cameras; each with their own custom loadouts.
      * Three, highly detailed external 3d models, including the RF-5A, whose nose was graciously modeled by ravenclaw_007.
      * Specular color and Normal (bump) maps on all models
      * Seven Level of Detail models (LODs) for each model, providing an almost seamless transition from distance to distance; and perhaps more importantly, ensuring that the frame-rate "impact" of the aircraft is as low as possible.
      * Two sets of highly detailed external Fuel Tanks by ravenclaw_007; both the Factory variety and the Sargent Fletcher variants.
      * Fine-tuned flight parameters in three distinct aircraft data configuration files  for all 3-D models, emphasizing the F-5A's agile and highly maneuverable characteristics - courtesy of  Baffmeister.

      * Quality sound-set included. Base sounds, by Guuruu, were sourced from existing recordings of various aircraft at air-shows and were modified  to match the prominent characteristics of the F-5A General Electric turbojets, the "buzz" of the M39 Pontiac 20mm machinegun, and the flap/Air-brake, undercarriage deployment and retraction sequences of the Freedom Fighter.
      * Super detailed  'Virtual Cockpit'  with animated throttle control, rudder pedals, control stick,  landing gear lever, canopy, canopy lever, drag-chute lever, weapons selectors and weapon station arming flick switches.
      *Accurate and functional representation of the Norair F-5A gun sight, with animated Mils selector and accompanying animated combining glass. (Mechanics by Crusader)
      * A full complement of highly (or should I say "insanely" detailed  HAF weapons carried by the HAF F-5A, all by ravenclaw_007.
      * Complex animation of canopy opening mechanism, and animated Turbine blades; both thanks to ravenclaw_007
      * GKAB's superb highly detailed crew figure with authentically modeled oxygen mask and flight helmet.
      * All new afterburner, emitter, and engine smoke effects by Guuruu.

      F-5A Limit and Reference Speeds. [Indicated Airspeeds]
      FLAPS: 300kts for both leading and trailing edge.
             NOTE: The F-5A uses full flaps for take off but due to a game bug you must manually select full flaps for take off when player flown. The        AI will use full flaps although you can hear the flap sound cycling between flap 1 and flap 2.
      LANDING GEAR: 240kts
      DRAG CHUTE: 165kts
      CANOPY: 50kts
      NOSE WHEEL STEERING: 65kts
      MAXIMUM INDICATED AIRSPEED: 710kts [redline]

It has been our goal to provide to the simmer a highly detailed model and texture base which preserve the beautiful lines of this aircraft; and to engineer flight files and a cockpit/gauge file-set that are authentic and add to the immersion of the flying experience within the Strike Fighters 2 series.

       
      INSTALLATION INSTRUCTIONS:
      --------------------------
      1. Copy the contents of the "To Mods Folder(S)" to your SF2 Mod directory.
      Allow directory merging and overwrites, provided the overwrites pertain to "fake pilot" entries, as well as weapons made by ravenclaw_007, which are included in this and many other releases.
      2. Add the entries of "ADD_TO_SOUNDLIST.txt" to your SOUNDLIST.INI (located in the "user\Saved Games\ThirdWire\StrikeFighters2\Flight" folder).If one does not exist, then you will need to extract it using the 3rdWire CAT extract utility.  You are simply required to substitute the "XXX"s  with the next sequential number in the sound file section of the file.
       
        NOTE    1:
      ------------
      Both Regular and Higher resolution cockpit textures are included in their own distinct folders in the package.
      The user may alternate between the two by "commenting out"
      the relevant line in the F-5A_STANDARD_COCKPIT.ini

      [CockpitData]
      //Directory=cockpit      
      Directory=cockpit_Lo-Fi    <---This is the default

      In order to "activate" the higher resolution textures
      you would decomment the previous line and comment out
      the next line, thus:

      [CockpitData]
      Directory=cockpit          <---This is now Hi-Res
      //Directory=cockpit_Lo-Fi    

        NOTE    2:
      ------------
      Another frame-rate friendly option for those with older hardware is to use the Next level of Detail Model as the primary external model. This simply involves changing the first line in the F-5A_HAF.ini  from this..
      [LOD001]
      Filename=F-5A_STANDARD.LOD
      to this..
      [LOD001]
      Filename=F-5A_STANDARD_002.LOD
      Much effort was made to provide those with lower end systems an alternative lower poly-model to be able to enjoy the F-5a,  so please take advantage of this _002.LOD model should you experience frame-rate issues.  While not as "rounded" as the Higher poly version, it is nonetheless just as detailed and extensive.
       NOTE    3:
      ------------
      For those who may find loading times excessive, the .jpg files in the texture folders can be reduced to 50% of their size without sacrificing too much surface detail.

      ****************************************************************
      FEATURES:
      * Three model set including the HAF F-5A standard version (1965 - 1974), the  HAF F-5A with Martin Baker IRQ-7a ejection seat  (1975 - 1999), and the  HAF RF-5A reconnaissance variant with 4 K-92a cameras; each with their own custom loadouts.
      * Three, highly detailed external 3d models, including the RF-5A, whose nose was graciously modeled by ravenclaw_007.
      * Specular color and Normal (bump) maps on all models
      * Seven Level of Detail models (LODs) for each model, providing an almost seamless transition from distance to distance; and perhaps more importantly, ensuring that the frame-rate "impact" of the aircraft is as low as possible.
      * Two sets of highly detailed external Fuel Tanks by ravenclaw_007; both the Factory variety and the Sargent Fletcher variants.
      * Fine-tuned flight parameters in three distinct aircraft data configuration files  for all 3-D models, emphasizing the F-5A's agile and highly maneuverable characteristics - courtesy of  Baffmeister.
      * 8 high resolution texture sets; thoroughly researched historic depictions of the Aircraft fielded by many HAF Wings and Squadrons.
      * Quality sound-set included. Base sounds, by Guuruu, were sourced from existing recordings of various aircraft at air-shows and were modified  to match the prominent characteristics of the F-5A General Electric turbojets, the "buzz" of the M39 Pontiac 20mm machinegun, and the flap/Air-brake, undercarriage deployment and retraction sequences of the Freedom Fighter.
      * Super detailed  'Virtual Cockpit'  with animated throttle control, rudder pedals, control stick,  landing gear lever, canopy, canopy lever, drag-chute lever, weapons selectors and weapon station arming flick switches.
      *Accurate and functional representation of the Norair F-5A gun sight, with animated Mils selector and accompanying animated combining glass. (Mechanics by Crusader)
      * A full complement of highly (or should I say "insanely" detailed  HAF weapons carried by the HAF F-5A, all by ravenclaw_007.
      * Complex animation of canopy opening mechanism, and animated Turbine blades; both thanks to ravenclaw_007
      * GKAB's superb highly detailed crew figure with authentically modeled oxygen mask and flight helmet.
      * All new afterburner, emitter, and engine smoke effects by Guuruu.

      F-5A Limit and Reference Speeds. [Indicated Airspeeds]
      FLAPS: 300kts for both leading and trailing edge.
             NOTE: The F-5A uses full flaps for take off but due to a game bug you must manually select full flaps for take off when player flown. The        AI will use full flaps although you can hear the flap sound cycling between flap 1 and flap 2.
      LANDING GEAR: 240kts
      DRAG CHUTE: 165kts
      CANOPY: 50kts
      NOSE WHEEL STEERING: 65kts
      MAXIMUM INDICATED AIRSPEED: 710kts [redline]
      MAXIMUM MACH: 1.72 Mach design limit but thrust/drag limited to about mach 1.50 in a 60deg dive from 50,000ft.
      --------------------------------------------------------------------------------------------------------------------------------
      TAKE OFF ROTATION SPEEDS
          13500lbs: 155kts [full internal fuel and two sidewinders]

      *****************************************************
      This mod is made for SF2.
      ----------------------------------------------------------
      I. History (fiction)
      In 1969 there were decisive elections in West Germany. In reality, the Social Democrats won.
      A new foreign policy followed and a period of reduction of tensions between East and West.
      WHAT IF, the other side had won?
      What if the conservatives had won and Franz Joseph Strauß (an old bavarian Commie eater) would have become Chancellor of the Federal Republic of Germany?
      And so it starts.
      In 1969 Strauß was elected as Chancellor. A period of rising tensions between East and West
       started. To protect the sea lanes between Europe and America the west german parliament Bundestag decided to build up a west german carrier force consisting of 3 carriers.
      The american gouvernment was pleased and offered to sell 3 carriers of the Essex class (subclass Ticonderoga).
      The first ship which was handed over was CV-34 Oriskany in 1969. Renamed in R-22 Theodor Heuss it was core of the first west german carrier group. 1973 CV-38 Shangri-La became R-23 Heinrich Lübke (later renamed in Walter Scheel) and two years later CV-45 Valley Forge became R-24 Gustav Heinemann.
      The americans offered A-4 Skyhawk and F-8 Crusader as planes for the carrier group. The Bundesmarine accepted the A-4, but rejected the Crusader, because the Bundesmarine wanted a more multi role capable plane, not only a pure fighter.
      At this moment Northrop entered the competition and offered a navalised version of the brand new F-5E Tiger. Under the designation F-5GN (German Navy) it should be produced in America and Germany. The west german government accepted the offer and the serial production of the F-5GN started. During flight tests on the way the US Marines decided, that it would be a good idea to replace their old F-8 Crusaders with F-5GN planes. So the F-5GN became a Marine plane.
      Later, when the Marines retired their attack carriers the surviving F-5GN were transfered to Top Gun school.
      The F-5GN stayed in west german service till 1995. Then it was replaced by F-31 Mustang II.

      ~~~~~~~~~~~
      The blue skin is a modification of a grey skin available in Centurions package
      The Marines skin is a mod of the Southvietnames skin available in Centurions Package
       

      The flight model :
      ~~~~~~~~~~~~~~~~
      There are 2 flightmodels. One is a modified FM from package. I made the plane able to land on a carrier.
      The other FM i made by using parts of the stock F-16A FM made by TK.

      You find both FM in the folder "Goodies". You may change them as you want.
