Su-21S/P "Flagpole"


When the Su-21S, codenamed "Flagpole" by NATO, appeared in 1978, it surprised the West which initially thought the plane to be just another failed Flagon update experiment or a testbed for systems of the recently identified Ram-L or Ram-K aircrafts.
It turned out to be a long endurance PVO interceptor, possibly meant as an interim or low-cost alternative to these new designs, using a clearly Flagon inspired but brand-new airframe and, according to some intelligence, reusing existing systems to mitigate development risk.
The aircraft is purported to use a single uprated R-35 derived from the one already used in PVO Floggers for propulsion, also borrowing the MiG-23P's radar, albeit with a larger antenna and more powerful emitter and using R-24 and R-60 missiles (up to 4 of each for a total of 8). It has been seen using up to 3 large drop tanks to accomplish its goal of long endurance patrol in the defence of the central and eastern regions of the USSR. Going against the trend of recent PVO-only interceptors, the Su-21 has 2 internal guns, sources suggesting these to be weirdly old-fashioned NR-30 with a hundred rounds each, as well as what seems to be decoy launchers.
This surprisingly elegant design was joined in 1980 by a dual-seat version, initially thought to be a trainer, but proving to be another interceptor, the Su-21P. While the single-seater Su-21S became a not too uncommon sight on the Soviet Western frontier, the Su-21P was almost absent, being more common on the other borders, the exact operationnal reason remains unclear as these planes seem to be otherwise identical.
Recent sightings suggest that the plane might not be a PVO exclusive as what are thought to be Su-21s were spotted in AV-MF colours, but not enough is known at present.

 

NOTEWORTHY OBSERVATIONS

- As it was started as an AI only asset for my own use, I kept the original F-15 cockpit.
- Likewise, as an AI only asset for my own use, I haven't taken the time to produce hangar and loading pics.
- I did the minimal amount of modification to the INI.
- All skins can be used on both variants if you want to switch things around.
- I have included AV-MF inspired skins in the Su-21P folder, for those that might be interested (waves at Stratos), they should be considered a not so hidden easter egg.
- PSD templates specific to this Soviet version should be released alongside.
- Read the damn READ ME for install.

CREDITS

Everyone at Cocas Aircraft Factory for their work on the plane, and especially Cocas for listening to my whin... errrr... suggestions and always nicely doing what I was pestering him to do (the guy is just too nice for his own good) and to Nyghtfall for giving us the templates without which I probably wouldn't have bothered to do something in a releasable form.
AmokFlo for the ejection seats.
The Trooper for the pilot reskin.
(I believe) PauloPanz for the Dark Blue Soviet numbers decals.
(I believe) Lindr2 for the R-24 and R-60.
Any error or omission is just that, feel free to correct me if I forgot or misattributed anything, everything should be under the CA Fair Use umbrella unless I messed up.

Have fun and good flight

Version 1.0 - 15/05/2020
    Nyghtfall :
        Original skins and templates, he did the hard part of the job
    Cocas :
        Dual-seat LOD
        Elevator modifications
        Specular map support
        Soviet variants
    Gunrunner :
        Mostly pestering poor Cocas for changes
        Normal/Specular/Holes maps
        Minor INI changes
        Bringing parts together
        Getting the credit for other people's hard work, then profit from it somehow and maybe, tomorrow, world domination ! Muwahahahahahahahahah... cough... cough... cough...

This as two seater can be AI  Su-19UM (T-58PS), proposed and never built version of Su-15, Russian answer to early F-15A

      F-5GN(Soviets)  (What if)
      *****************************************************
      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 consiting 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.
      1973 the government of South Vietnam demanded more F-5E Tigers to fight the communist forces. Because there was a shortage of F-5E the american leaders decided to send the first batch, which was intended for the Marines, to the Republic of Vietnam. So 40 F-5GN were handed over.
      On May 1st 1975 Saigon was taken by the communist forces. the war was over. 36 surviving F-5GN were captured by the north vietnamese. To pay war depts  Vietnam handed all 36 F-5GN and 12 F-5E to the soviets.
      In the USSR the planes were tested very hard. Finaly the decision was made to use the F-5GN in the Soviet Navy. The canceled carrier project Oriol was revitalized and in 1976 the first soviet carrier squadron was formed. The soviets modified only the RWR and the air to air missiles. Air to ground weapons were taken from captured stores in Vietnam.
      The US Navy realized very soon that the soviets had a new plane. Analysts believed, that the soviets copied the F-5GN and gave her the designation MiG-28.
      The F-5GN alias MiG-28 had only a short service time in the Soviet Navy.
      1982 the F-5GN was withdrawn from service. The reason was missing spare parts.
      Afterwards the planes were sold to Iran.

      Templates for the Sukhoi Su-21 "Flagpole" for STRIKE FIGHTERS 2 
      These templates are Photoshop versions derived from my own Paint.NET files, themselves based on Nyghtfall's original work.
      Layers starting with :
          NM are for generating the Normal Map
          SM are for generating the Specular Map
          DM Mask are masks for generating various camo patters for the Diffuse Map
          DM are for generating the Diffuse Map
      I hope everything is clearly labelled, I have flattened existing skins to conserve space and reduce the number of layers, but the presence of masks and the palette should help if required.
