=== In-game description ===
Petlyakov Pe-3bis Heavy Twin-Engine Fighter.

In April 1942, the Pe-3bis, an improved version of the Pe-3, began full-scale production. The most significant improvements concerned the main armament: a 20 mm ShVAK cannon with 250 rounds was installed in the nose fuselage section. Two 12.7mm Berezin UBK machine guns were placed under the center wing section where the Pe-2's bomb bay once had been. The starboard gun had 230 rounds, whereas the port gun was given 265 rounds. A VUB-1 defensive turret was mounted at the navigator's station and had a 12.7mm UBK machine gun with a pneumatic reloading system and 200 rounds. A 7.62mm fixed ShKAS machine gun with 250 rounds was put in the tail cone.

Various changes and improvements were introduced into the airframe structure and the plane's equipment. The wing panels of the Pe-3bis were equipped with automatic leading edge flaps. The crash pylon was removed from the crew cockpit to improve the navigator's working conditions, and the cockpit armor was reinforced. Only a part of the glazing on the nose fuselage section was left, namely a pair of narrow side blisters and a small navigator's porthole to aim when bombing. Blackout shutters were provided for the whole of the cockpit glazing.

The nitrogen fuel tank pressurization system was replaced with one that used cooled inert gases fed to the tanks from the engine exhaust. Transferring the battery of guns to the center wing section required reduction of the capacity of fuselage fuel tank No. 7 by 100 liters. An asbestos bulkhead separated the tank from the machine guns and, at the same time, protected the weapons from dripping gasoline.

121 Pe-3bis aircraft were built in 1942. The industry provided the front lines with 13 more planes at the beginning of 1943. Due to the relatively small production volume, different changes were introduced occasionally in the Pe-3bis design and were subsequently applied to full-scale production Pe-2s, if these changes had proven to be effective. The following items appeared and were tested on production Pe-3bis planes: a VUB-1 upper turret, a new canopy for the pilot's cockpit, increased forward projection of the main landing gear legs, an advanced fuel supply system, and an inert gas fuel tank pressurization system.

An attempt to resume the production of Pe-3 fighters was made at the beginning of 1944. For a variety of reasons, this version of the fighter did not meet the Air Force's requirements. Its armament was outright weak: one 12.7mm UBK machine gun in the nose fairing and only one 20mm ShVAK cannon in the center wing section.

Since the DEU-1 remote-controlled defensive mount which had been planned for installation was not ready, two DAG-10 grenade launchers with AG-2 aerial grenades were fitted in the rear fuselage section, instead.

Due to the aircraft's obvious non-compliance with the requirements of the specification, only 19 production Pe-3 planes of this variant were built.

Pe-3/Pe-3bis fighters were in service only with the Air Force of the Workers' and Peasants' Red Army and naval aviation. As part of the Air Force of the Northern Fleet, several planes outlasted the war and served until 1946, and the final Pe-3s survived up to the beginning of the 50s.

== Description ==

[[File:GarageImage_I-185M-71.jpg|420px|thumb|left|The '''{{PAGENAME}}''' in the garage]]
{{break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Russian fighter {{Battle-rating}}. 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 (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.

=== Pros and cons ===


'''Pros:'''

* 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

'''Cons:'''

* '''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

=== 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."
