Yakovlev Yak-36 Freehand, VTOL v2.5 with new variants SMFAn Add-On for Il-2 1956 by the SAS Modding CommunityYak-36 FreehandHistory:From 1960, the Yakovlev Design Bureau began work on a VTOL system, using the compact and lightweight Tumansky RU-19-300 turbojet engine, drafting a proposal for the Yak-104, a converted Yak-30 jet trainer with two vertically mounted Ru-19 engines between the inlet ducts of the standard Yak-30 powerplant. Work on the Yak-104 was terminated in favour of an aircraft with a single lift/cruise engine with rotating nozzles, similar to the Hawker Siddeley P.1127, which was nearing completion in England. Unable to find a suitable engine or convince the government to order the development of one the Yakovlev bureau was forced to follow a different course.
In response to a contract for the development of a single seat V/STOL fighter in 1961, Yakovlev proposed a twin engined aircraft with a large nose intake, engines in the forward fuselage and swivelling exhaust nozzles, one for each engine either side of the lower fuselage near the centre of gravity of the aircraft. The fighter version was not proceeded with but four technology demonstrators, (initially designated Izeliye V) based on the fighter studies were ordered.
Four prototypes were completed, one of which was used only for static testing. The second was used for takeoff and landing tests, including free hovering. The third incorporated improvements found in testing, including an improved autopilot which automatically selected optimal air flow for hover stability. This prototype crashed, but was later rebuilt. The fourth prototype crashed in February 1971 and was not rebuilt.
Alternative History:
Thanks to its rapid respond and ability to operate in non-airfield bases, it was favored by many front line commanders as bases point defences and extreme close air support. It have enough range and loiter time to keep situation under control until dedicated aircrafts arrived. Though this is not a good fighter and you'll find yourself in a very tight situation fencing against dedicated fighters like F-4, F-8, MiG-21, 19 or even MiG-17.
Yak-36SMF Freehand-DAlternative History:
Since the development of the Yak-38 was not very successful. Yak-36 design was once again re-considered and invested. Thus the new combat worthy Yak-36SMF was designed, mass-produced and put into action.
Even though the aircraft externally looks like a Harrier, but it have purely Russian Technology:
Powered by a pair over-powered Tumansky R-27-2000 that produce 5500kg dry thrust each, this aircraft can carry more oridiance and still beable to use S/VTOL. (USE Arrestor Hook Key)
Ordinance can be hang on 8 hard points with a total weight up to 2500kg, consisting of AAM, AGM, free fall bombs and droptanks. It was also fit with NR-23-6 gatling cannon.
It was fit with a slightly modified RP-22 Radar, the RP-22-N, which have limited capability to look down, shoot down (above 2500m altitude). Radar lock display are moved to the HUD to assit pilot in intercepting with air to air missiles and using gun. Locking are automatic. This upgraded version of this radar also have limited ability to scan and identify moving ground target. Use radar mode key to switch to ground attack mode.
Radar spec:
Scan range: 30km
Lock range: 15km
Max angle horizontal: +/- 35O
Max angle elevation: +/- 15O
This aircraft featured a mini HUD for this aircraft that based on the MiG-23 layout. Use Toggle bombsight automation key to switch between different HUD mode.

Ground attack
Several aircrafts are also exported to many country in the world.
To use vertical take off landing:Use your deploy refueling probe key.
When on ground, start your engines, when both engines started, deploy your refueling probe then slowing increase your throttle until the plane lift off. You can use your control surface (ailerons, rudders, elevator) to move the aircraft around. You can deploy flap to 15 degree to ensure safe transition to horizontal flight. For the latest patch, you can switch to horizontal flight when just barely lift off the ground. retract your refueling probe for horizontal flight. Notice that when transit to horizontal flight, you'll experience a sudden drop due to lack of thrust, just use maximum throttle and pull up then you'll be okay. landing gears and airbrake can be retracted before or after switching to horizontal flight, or even in between.
For landing just slow down to 400km ( don't throttle below 50%, only use your airbrake) then deploy arrestor hooks. The plane will slowly get slower until you stay still. Use your control surface to keep the plane stable and move them around, then use throttles to lower the aircraft.
Just practices a few rounds, you'll get used to it.
