The I-185 (M-71) in the garage

The I-185 (M-71) is a rank IV Russian fighter with a battle rating of 4.3 (AB/RB/SB). This aircraft was introduced in Update 1.41.

The I-185 (M-71) is a monoplane with a Shvetsov M-71 engine, the plane is fitted with 3 x 20 mm ShVAK cannons mounted at the fuselage of the I-185. The left cannon has 140 rounds, right cannon 170 rounds, and the top cannon 250 rounds. The fuel tanks of the I-185 are self-sealing and located in the fuselage and in the wings.

The I-185 (M-71) is a dedicated Boom & Zoom fighter for its battle rating and needs to always keep its energy levels at a good level to hunt down players.

Survivability and armour

  • 8 mm Steel - armour plating behind pilot's seat
  • No armoured glass
  • Critical components located in front of aircraft, centralized in the fuselage (fuel, pilot, engine, controls, guns)
  • More fuel tanks located in wings near the fuselage


Offensive armament

Main article: ShVAK (20 mm)

The I-185 (M-71) is armed with:

  • 1 x 20 mm ShVAK cannon, top nose mount (250 rpg)
  • 1 x 20 mm ShVAK cannon, right side nose mount (170 rpg)
  • 1 x 20 mm ShVAK cannon, left side nose mount (140 rpg)

Suspended armament

The I-185 (M-71) can be outfitted with the following ordinance:

  • Without load
  • 2 x 100 kg FAB-100 bombs (200 kg total)
  • 4 x 100 kg FAB-100 bombs (400 kg total)
  • 2 x 250 kg FAB-250M43 bombs (500 kg total)
  • 8 x 82 mm RS-82 rockets
  • 8 x 82 mm RBS-82 rockets

Pros and cons


  • Once engine injection upgrade has been purchased, the plane has a brutal climb rate (close to 28 m/s)
  • 3 x 20 mm nose-mounted cannons have decent amounts of ammo (for Soviet standards) and have workable damage output (note that all the cannons have different ammo counts)
  • Great roll rate, comparable to that of Fw-190s
  • Surprisingly manoeuvrable at higher speeds
  • Able to safely dive up to 799 km/h IAS
  • The ramming effect of the air at higher speeds significantly help with the engine performance when above the critical altitude of the supercharger gears
  • Has good ordnance options, making the aircraft viable for CAS in Ground RB


  • Not a turn fighter, having terrible turn against most opponents
  • Top speed is nothing special when compared to most USA aircraft, but is still better than most Spitfires and most Japanese aircraft
  • Combat flaps break when above 380 km/h IAS
  • First supercharger gear is just for show, losing engine performance after 500 to 800 meters altitude! (And being replaced by 2nd gear at 2,000 meters)
  • The first supercharger gear is ineffective to the point of the aircraft using the second supercharger gear when parked with the throttle at idle (of course in Automatic Engine Control)
  • Second supercharger gear only lasts up to about 3.5 km altitude
  • MASSIVE loss of engine performance after 4 km altitude
  • Performance is only "workable" under ~5 km altitude


Describe the history of the creation and combat usage of the aircraft in more detail than in the introduction. If the historical reference turns out to be too big, take it to a separate article, taking a link to an article about the vehicle and adding a block "/ historical reference" (example: https://wiki.warthunder.com/Name-vehicles/historical reference) and add a link to it here using the main template.

In-game description

"Following combat test results, production began on a new I-185 prototype in Novosibirsk, which, during its evacuation, was home to the N.N. Polikarpov design bureau and experimental plant. This prototype was intended to be a standard for series production. The designer corrected several flaws from the previous models in this aircraft, which is sometimes called the I-186, and combined its triple-cannon armament with the M-71 engine. The I-185/M-71 Series Standard took its maiden flight on 10 June 1942.

The plane was powered by the 18-cylinder twin-row air-cooled Shvetsov M-71 radial engine with a rated output of 1,625 hp (maximum power in emergency mode – 2,000 hp). It had the three-blade variable-pitch AV-5-119 metal propeller. It used 2B-78, 3B-74 and B-95 aviation fuel with an octane rating of no less than 90.

The M-71 engine hood's shape was altered and the plane's airframe made more aerodynamic.

The I-185/M-71 Series Standard possessed three 20 mm synchronized Shpitalny-Vladimirov ShVAK cannons with 500-600 shells overall (tests were conducted with various amounts of ammunition). The central cannon had 250 shells, the left 140 shells, and the right 170 shells.

The plane could carry up to 500 kg of bombs of various types (FAB-250, FAB-100, FAB-50, FAB-25) on four bomb racks mounted under the wing panels. As expected, the new I-185 possessed even better characteristics. In plant tests, it reached a speed of 680 km/h, but the new engine continued to fail.

Only one I-185/M-71 Series Standard was built. The airplane was not put into service.

N.N Polikarpov received a 1st degree Stalin Prize for creating the I-185/M-71 Series Standard in 1943."
