Description

The Pe-3bis is a rank II Russian twin-engine fighter with a battle rating of 3.3 (AB), 2.7 (RB), and 3.0 (SB). It has been in the game since the start of the Open Beta Test prior to Update 1.27.

The Pe-3bis is the final aircraft in the Pe-3 family of twin-engine fighters, and shares similar characteristics with it's other bethren. It features an impressive array of secondary weapons, making it an effective ground attacker. It can also be used in as an effective air-defence fighter and bomber hunter, taking advantage of it's airspawn and powerful frontal armament. Overall, this aircraft is a great multirole fighter suitable for both Air and Mixed battles.

General info

Flight Performance

The Pe-3bis has similar handling characteristics as it's predecessor, the Pe-3. It isn't a very manuveurable aircraft, and has mediocre handling characteristics even for a twin-engined heavy fighter. The plane can attain a top speed of roughly 430 kph at sea level when spaded, and up to 530 kph at higher altitudes. This means that the aircraft is much slower than most enemy single-engined fighters and some of it's twin-engined bethren (for example, the Me 410). The plane also has a slow climb rate, meaning that gaining altitude is always going to be a pain.

This aircraft benefits from having control surfaces that are relatively large and responsive. In particular, the aircraft's roll rate is actually quite satisfactory for an aircraft of it's size. However, being a heavy fighter, the Pe-3bis suffers from relatively bad energy retention and turning capacity. The aircraft suffers from slight control-surface lockup at higher speeds, but this isn't severe enough to prevent the aircraft from pulling out from a steep dive.

The aircraft's engines are another weak point, as their oil coolers are rather ineffective. As a result, the aircraft's engines will begin to overheat after just 30 seconds of WEP, even when spaded.

Survivability and armour

• 6 mm steel plate in front of the pilot
• 7 mm steel plate in front / partially below the pilot
• 45 mm bulletproof glass in front of pilot
• 13 mm armoured seat for pilot
• 6 mm steel protecting sides of gunner cabin
• 10 mm steel underneath gunner
• 12 mm steel behind gunner
• Fuel tanks are located behind the gunner and in the wing, are self sealing and feature a neutral gas pressurization system

This aircraft benefits from strong armour protection for both crew members, featuring 6-13mm steel plating for the pilot cabin. As well, the pilot has a 45mm bulletproof glass plate in the front of the aircraft. The fuel tanks in the wing can often survive fires due to their pressurization system.

However, the plane is still rather fragile. The central fuel tank (behind the gunner) is well-protected but can often cause structural failure if set alight. As well, the engines are unprotected and can easily be knocked out.

Armaments

Offensive armament

The Pe-3bis is armed with:

• 1 x 20 mm ShVAK cannon, nose-mounted (250 rpg)
• 2 x 12.7 mm Berezin UB machine guns, belly-mounted (265 rpg left + 230 rpg right = 495 total)

Suspended armament

The Pe-3bis can be outfitted with the following ordnance:

• 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 + 2 x 100 kg FAB-100 bombs (700 kg total)
• 6 x RS-132 rockets
• 6 x RBS-132 rockets

Defensive armament

The Pe-3bis is defended by:

• 1 x 12.7 mm Berezin UB machine gun, dorsal turret (200 rpg)
• 1 x 7.62 mm ShKAS machine gun, tail turret (250 rpg)

It should be noted that the 7.62mm machine gun has a tiny firing arc making it almost useless in all engagements. Thus, the main line of defence of the Pe-3bis is it's 12.7mm machine gun. This weapon has decent coverage over the upper hemisphere, but cannot fire underneath the aircraft. As a result, the aircraft is completely undefended against attacks from below.

Usage in battles

The Pe-3bis is a very effective multirole aircraft that can be configured for a variety of missions. Firstly, the aircraft benefits from an airspawn, allowing it to reach the battlefield much faster. As well, the aircraft is decently-armoured and has great armament options, meaning that it can be used in both bomber-hunting and ground-attack roles. These two main paths will be discussed below:

Ground Attack:

Though initially configured as a bomber-hunter, the Pe-3bis benefits from a strong set of secondary payload options. These include up to 700 kg of bombs (2x250 kg mounted underwing and 2x100kg in the engine-nacelle bays). The aircraft can also carry up to six RS/RBS-132 rockets for use against armoured ground targets. These secondary armaments make the aircraft very effective against ground targets.

In Air RB, one option is to bring the attack load and skim the ground, with the aim of reaching the ground targets as fast as possible. The 2x100kg + 2x250 kg load is quite effective against hard targets, but can only hit 3 targets due to the 250 kg bombs dropping in pairs. The 100 kg bombs drop singly out of each engine nacelle bay, but have a smaller blast radius meaning that it will be harder to kill Tanks and pillboxes with it. The RS/RBS-132 rockets are very effective against harder targets, but take some time to get used to aiming - however, the RBS-132 lacks an explosive charge and typically does less damage. Take note that the rockets fire in pairs.

In mixed battles, the aircraft can be effectively used as a multirole aircraft, utilizing it's strong armaments. The aforementioned rockets and bombs can be used to deal with tanks and harder targets - however, note that the 20mm ShVak cannon can also be used against softer targets. The cannon is capable of penetrating 27mm of armour when using Armoured Target belts, which is more than enough to deal with softer targets such as SPGs and SPAAs.

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.
