Shipbucket :: Fleet Air defence fighter of 1980 challenge

The Walraven MA-6 GriffinII is an twin-engined, all-weather tactical fighter aircraft designed by Walraven(now CAWAKO)to gain and maintain air supremacy in all aspects of aerial combat. Following reviews of proposals, the Royal Nayy Rochfort selected Walraven' design in 1970 to meet the service's need for a dedicated air-superiority fighter. The GRIFFINII first flew in July 1975, and entered service in 1979.

My idea is to have the judging done as in OP, it means three different votes, which results will be allocated into points that makes up the final score.

No worries, lets see how it goes; good luck!

I have to say I'm in agreement with Deskjetser; this competition contains some of the best FD Scale aircraft drawings the bucket has seen in a long time--when have we ever had this many designs, by so many individuals, most of them offering multiple views in a single thread? It would be a shame if all this effort came down to little more than a collection of numbers in a poll, and I doubt I'm the only one who wants to hear more feedback and more about the merits of the different entries relative to each other, than merely what we'd get from poll votes alone.

everyone is offcourse free to post their feedback of the resultants, but by kind request, lets start with those after the submitions closes That way, Im sure everyone will be just thrilled with enthustiasm to offer their deep analyzes and calculations, in similar plenty manner and variety than they have done by contacting me and offered themselves as judges

The 1970s were a rather unstable time for the Greater Holy Russian Republic as the end of the Zhukov era led to minor led to minor infighting among the higher ranking Generals and Admirals. This resulted in several failed governments and coups, but by 1978 the situation had stabilised enough for the Admiralty to put out tenders for new carriers that would be able to compete with the Japanese and British Designs. Unfortunately Russian Aviation had been stagnant ever since the mind 60s due to the retirement or deaths of major designers but efforts among the newer designers eventually bore fruit as a young and up and coming designer from the Ukraine had come up with a couple of advanced trainers and was working on a land based fighter when the tender for a carrier based interceptor was concived. She started work immediately on the new fighter. By 1980 the first prototype took off using a pair of Arkhangelsk Ark-302/A engines though the engines selected for the full production model were the C variant which offered a better afterburner and fuel efficiency. The fighter was fully operational by mid-1983 with the 44th Shipborne Fighter Aviation Regiment on the carrier Alexander Kolchak. Max speed was around Mach 2.4 with full afterburner Weaponry included 2 AA-13 pike, 4 AA-16 sabre 2 AA-10 snake missiles and a GSh-6-23 rotery cannon with 300 rounds of ammo in the port wing

Well here's my entry. This was actually the fourth aircraft which I draw for this competition as alongside to mach the design challenge, I started to sort out the aircrafts of my next AU project waiting for release. So this will serve as a taster. Initially I was to post the aircraft which this one replaced in service but someone used the name of it in their own entry (the aircraft was however completely different) so thus I decided to go with the follow-on development. So here we go, AU Yugoslavian Soko L-20K Belorepan (alias 'Naval Novi avion') Spesifications: Crew: 2 Lenght: 16.2m Wingspan: 9.2m Height: 4.82m Wingarea: 33m2 Empty weight: 7 800kg Loaded weight: 9 700kg Max. takeoff weight: 19 200kg Powerplant: 1 M78M Sava-M afterburning turbofan -Dry thrust: 76.3 kN (17,155 lbf) -Thrust with afterburner: 125 kN (27,999 lbf) Max. speed: Mach 1.88 Combat radius: 550 km Ferry range: 3 765 km Service ceiling: 18 000m Armament: 1 30mm cannon, 11 hardpoints for total of 7 000kg of ordnance Development: In 1980 issue was given to develope a new multipurpose warplane to meet the new challenges of the 80's and effectively replace all current light and medium weight combat aircrafts in service with RV i PVO and with the Naval aviation. One of the main catalyst for the program was the emerge of new American fourth generation fighters both in US and its allies serivce in the 70's. Also Yugoslavia followed the trend if having "high-low" mix (IAR-101 being the heavy air superiority fighter) of its main fighter force and thus the new aicraft project, initially labeled as Novi Avion was started. Both I.A.R and SOKO competed for the task but the later was given go-ahead as I.A.R was busy developing modified model of its IAR-101. As with the corresponding designs abroad, need for superior manuevrability was one of the leading paraments of the program. SOKO studied several different configurations and ended up using tailess-delta/canard design with underfuselage intake. It was one of the first of group of fighters with similar layout often called "Euro-canards". First prototype flew in 1985 but the development moved slowly and the plane was only in prototype stage in 1991 when the collapse of USSR and the whole eastern block put severe economical restrains on Yugoslavia and the program was halted for several years. First operational units started to roll inot service in 2004. The plane was designed to naval service from the start and initially it was intended to field both single-seater and two-seater variants as with the Air Forces but with the decision to move towards several smaller carriers instead of few larger ones put new demands on the aircraft. It was tought that best possiple result would come from having just one airframe capapble of performing all the combat missions tasked for the naval aviation. Thus the JNRM decided to adopt only the two-seater version which was to serve as a air superiority, strike, ECM and RECCE aircraft roles.
