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. F-20 #2 (Northrop Grumman) 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). F-16N (Lockheed Martin) 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. F-20 Pre-production figures from Flight Manual F-20 #3 (Northrop Grumman) 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………….. The F-18L - another unloved Light Weight Fighter devoid of orders (Northrop Grumman) 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.
