The '''{{specs|name}}''' is a Rank {{specs|rank}} Russian tank destroyer {{Battle-rating}}. It was introduced in [[Update 1.59 "Flaming Arrows"]]. It was designed to provide the VDV (''Vozdushno-Desantnye Voyska''), the Soviet airborne forces, with an air-portable self-propelled gun for independent fire support and anti-tank capability in support of paratroopers during airborne operations.

=== Survivability and armour ===
 +
<!--''Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat?''
 +
 
 +
''If necessary use a visual template to indicate the most secure and weak zones of the armour.''-->
 +
The front upper glacis plate, while only 45 mm thick, is quite heavily sloped and can occasionally ricochet rounds. The mantlet is also quite thick and rounded, and it can also bounce the occasional lucky shot.
 +
 
 +
However, the rest of the ASU-85 is very thinly armoured and vulnerable to even heavy machine guns. It is especially vulnerable to aircraft strafing.
 +
 
 +
'''Armour type:'''
 +
 
 +
* Rolled homogeneous armour
 +
* Cast homogeneous armour (Gun mantlet)

{{tankMobility|abMinHp= 298|rbMinHp= 186|<!--AoAweight=(optional) -->}}The ASU-85 is based on the [[PT-76B]] and uses the same engine. It is somewhat heavier, however, and the mobility thus suffers comparatively. With a top speed of under 50 km/h, the ASU-85 is relatively slow for such a lightly armoured vehicle, but it is adequate enough for repositioning when needed. The ASU-85 also has a fairly slow reverse speed and only one reverse gear, inherited from the PT-76B.

The '''{{Specs|name}}''' is a rank {{Specs|rank}} American jet fighter {{Battle-rating}}. It was introduced in [[Update 1.33]]. It is found under the F-80 bracket, immediately after the F-80A-5.
 
  
The greatest performance upgrade from the A-5 to the C-10 is that the C-10 comes with WEP. This additional power significantly increases acceleration, allowing you to match that of the British Meteor series. It also allows for a last-resort method to escape if you happen to get jumped on. However, maximum power WEP only lasts for about 2 minutes, and once that runs out, the thrust increase by the less powerful WEP (now visible in gray instead of red), is not as significant.
+
It should also be noted that the ASU-85 is ''not'' amphibious, unlike the PT-76B it is based on.

=== Main armament ===
''Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.''
+
<!--''Give the reader information about the characteristics of the main gun. Assess its effectiveness in a battle based on the reloading speed, ballistics and the power of shells. Do not forget about the flexibility of the fire, that is how quickly the cannon can be aimed at the target, open fire on it and aim at another enemy. Add a link to the main article on the gun: <code><nowiki>{{main|Name of the weapon}}</nowiki></code>. Describe in general terms the ammunition available for the main gun. Give advice on how to use them and how to fill the ammunition storage.''-->
 +
{{main|D-70 (85 mm)}}The ASU-85 is armed with the '''85 mm D-70''', a significantly more powerful gun compared to the wartime Soviet 85 mm ZiS S-53 and D-5T guns and comparable in capability to the German 8,8 cm L/71 guns. The mounting has only 4° of gun depression due to the restricted size of the vehicle, but has a fairly generous amount of traverse for a casemate tank destroyer. It has a relatively low rate-of-fire for its calibre, reflecting the rather cramped crew compartment of the ASU-85.
 +
 
 +
The standard shell is the '''BR-372''' APBC shell with a lethal explosive filler. It has an excellent muzzle velocity and is accurate at long ranges. It will also easily penetrate most things that the ASU-85 may encounter. Anything that cannot be penetrated by the APBC shell will almost certainly be penetrable by the '''3BK7''' HEAT-FS round. Boasting 300 mm of penetration, it is capable of punching straight through a [[Tiger II (P)|Tiger II]]'s upper glacis and does not lose penetration over distance. However, it suffers the usual drawbacks of HEAT rounds (cannot go through obstacles like trees or fences) and is significantly less lethal than the APBC shell. The muzzle velocity is also lower, which can complicate aiming at long ranges.

The ASU-85 is a veritable glass cannon that relies on stealth and/or distance in order to survive on the battlefield. It is very vulnerable if caught in the open, especially to planes due to the very weak roof armour. The 85 mm gun is capable of handling almost any tank likely to be encountered by the ASU-85. Unfortunately, the ASU-85 lacks the mobility of its predecessor, the [[ASU-57]], and thus has to adopt a more passive playstyle. The stock APBC round is excellent for ambushes, which tend to involve a lot of side shots where the lethality of the explosive filler is valuable, especially with the long reload time of the gun. The HEAT-FS round is better suited for medium/long-range fighting, since it does not lose penetration over distance.  
Like most American props and tech, your best option to attack is Boom and Zoom. At the start of the match, fly out towards the edge of the map. Climb at 2-3 degrees until you have reached ~770 km/h (~420 knots) at ~910 metres (~3,000 ft), then zoom climb at 20-30 degrees. Once you have slowed down to 287 km/h (155 kt), continue to climb at a solid 10 degrees. Optimally, you should have between 3.7-4.9 km (12,000-16,000 ft) depending on how high the highest enemy is, before turning in towards the area of conflict (continue to climb or maintain altitude). Only once you have selected a target should you dive and make your pass. Always keep your energy high, whether it be speed or altitude. Because the F-80 is frequently uptiered to 9.0, the best option is to dive on unsuspecting targets that are occupied engaging your teammates.  
 
  
Defensive flying, rolling scissors, and to some degree, turn fighting, are options with the hydraulic boosters upgrade, as the straight wing as compared to 9.0 jets with swept wings provides better maneuverability at medium speeds (463-648 km/h, 250-350 knots). Any higher and the control surfaces begin to stiffen, any lower and you risk stalling out first, as jets with higher BR generally have a better thrust-to-weight ratio.
+
The ASU-85 has a rather unorthodox method of using its smoke screen. Unlike most vehicles, which use smoke shells, singular canisters, or canister clusters, the ASU-85 uses two large drum like structures at the rear. When deployed, these will drop away, so it is relatively easy to tell from close range whether or not an ASU-85 has smoke or not, and how many it has. Due to the orientation of the drums, the smoke screen will actually form ''behind'' the tank and take about 2-3 seconds to fully envelope the assault gun.
  
If you are given an awkward firing angle (e.g.: your target is near ground level and you are diving at a steep angle) or you fail to destroy them on your first pass, slowly pull your aircraft back up into a straight vertical climb to recover as much altitude as possible. If you persist on knocking out your target, you risk crashing into the ground from control stiffening or getting strafed by another enemy because you are losing your energy in a dogfight.

A new assault gun was requested by the Armed Forces sometime before 1953. Due to the success of the [[ASU-57]], they tasked the OKB-40 design bureau headed by Nikolaj Astrov to design the vehicle. The design, designated ''Object 573'', was ready for tests in the latter half of 1953. Constant changes and improvement was made from the span of 1956 to 1957. The design used the chassis of the [[PT-76B|PT-76]] amphibious light tank design, though it did not have the same amphibious feature and had a new engine propelling it. The armament was an 85 mm D-70 gun derived from the 85 mm D-48 anti-tank gun. The design could carry 45 rounds inside and could fire a variety of rounds up to 1 km away. Secondary armament for the vehicle was a GMT or PKT coaxial machine gun. The improved design was going to accepted and enter production in 1958 as the ''SU-85'' (despite the existence of [[SU-85|a vehicle of the same name]]), but this was again delayed when the Ministry of Defense ordered an armoured roof to be installed. The design was to enter production in 1961, but by then the design was rather outdated for army forces usage. Thus, when the vehicle entered production, it was taken up by the VDV, the Soviet Airborne Forces, and renamed the '''ASU-85'''. The ASU-85 was produced from 1959 to 1966, while staying in service from 1959 all the way to 1993.

The Soviet airborne forces primarily used the ASU-85 as a light infantry support/assault gun. Advancements in air-drop techniques and the advent of helicopters made its air deployment a more viable option in the early 1960s. The Soviet Union deployed 31 ASU-85s to each of its airborne divisions in and assault gun battalion. The Soviet Union used the ASU-85 during the Soviet-Afghan War with the airborne troops stationed there.
  
The first flight of the XP-80 prototype was performed in January 1944. The first production version, designated the P-80A Shooting Star, entered service in 1946. The P-80 became the first combat-capable jet aircraft to enter service with the USAAF.

The ASU-85 was only given out to Poland and Vietnam. Poland used the ASU-85s in the same manner as the Soviet Union, with 31 vehicles in each airborne divisions.

1947 saw the appearance of the next production version of the aircraft, the P-80B. The ninth production P-80A-1 was converted to a new prototype, designated the XP-80B. It had an Allison J33-A-17 turbojet engine producing 1,816 kg of thrust, equipped with a methanol-water injection system. The airfoil was thinner, but the skin's thickness was increased. To install a water mixture tank, the plane's fuel quantity had to be sacrificed by reducing it from 1,781 to 1,610 liters The aircraft also received a Lockheed-designed ejection seat and a cockpit air-conditioning system.

The ASU-85 also serves as the genesis of other support vehicles using the derived PT-76 chassis. The most notable vehicle using a similar chassis was the [[ZSU-23-4|ZSU-23-4 "Shilka"]] anti-aircraft system.
  
The plane's armament consisted of six 12.7 mm Colt-Browning M3 machine guns with 300 rounds each in the forward fuselage. One 1,000 lb (454 kg) bomb or ten 5-inch (127 mm) unguided HVAR missiles could be suspended under each wing panel.

A total of 240 P-80B fighter-bombers were built from March 1947 to March 1948, including P-80B-1s and 31 P-80B-5s. The В-5 variant was intended to be operated in Arctic conditions; its heated canopy prevented icing. In addition, special types of oil and special rubber were used to operate the aircraft in low temperature conditions.

Description

GarageImage ASU-85.jpg


The ASU-85 is a Rank IV Russian tank destroyer with a battle rating of 6.3 (AB/RB/SB). It was introduced in Update 1.59 "Flaming Arrows". It was designed to provide the VDV (Vozdushno-Desantnye Voyska), the Soviet airborne forces, with an air-portable self-propelled gun for independent fire support and anti-tank capability in support of paratroopers during airborne operations.

General info

Survivability and armour

The front upper glacis plate, while only 45 mm thick, is quite heavily sloped and can occasionally ricochet rounds. The mantlet is also quite thick and rounded, and it can also bounce the occasional lucky shot.

However, the rest of the ASU-85 is very thinly armoured and vulnerable to even heavy machine guns. It is especially vulnerable to aircraft strafing.

Armour type:

  • Rolled homogeneous armour
  • Cast homogeneous armour (Gun mantlet)
Armour Front Sides Rear Roof
Hull 45 mm (60°) Front glacis
45 mm (37°) Lower glacis
50 mm Driver port
6 mm 6 mm (40°) Upper
6 mm (18°) Lower
6 mm
Superstructure 45 mm (60°) Front glacis
100 mm Gun mantlet
13 mm (37-38°) 6 mm 13 mm Front
6 mm Rear

Notes:

  • Suspension wheels are 10 mm thick, tracks are 15 mm thick.

Mobility

Game Mode Max Speed (km/h) Weight (tons) Engine power (horsepower) Power-to-weight ratio (hp/ton)
Forward Reverse Stock Upgraded Stock Upgraded
Arcade 49 6 15.9 298 401 18.74 25.22
Realistic 45 6 186 210 11.7 13.21
The ASU-85 is based on the PT-76B and uses the same engine. It is somewhat heavier, however, and the mobility thus suffers comparatively. With a top speed of under 50 km/h, the ASU-85 is relatively slow for such a lightly armoured vehicle, but it is adequate enough for repositioning when needed. The ASU-85 also has a fairly slow reverse speed and only one reverse gear, inherited from the PT-76B.

It should also be noted that the ASU-85 is not amphibious, unlike the PT-76B it is based on.

Armaments

Main armament

Main article: D-70 (85 mm)
The ASU-85 is armed with the 85 mm D-70, a significantly more powerful gun compared to the wartime Soviet 85 mm ZiS S-53 and D-5T guns and comparable in capability to the German 8,8 cm L/71 guns. The mounting has only 4° of gun depression due to the restricted size of the vehicle, but has a fairly generous amount of traverse for a casemate tank destroyer. It has a relatively low rate-of-fire for its calibre, reflecting the rather cramped crew compartment of the ASU-85.

The standard shell is the BR-372 APBC shell with a lethal explosive filler. It has an excellent muzzle velocity and is accurate at long ranges. It will also easily penetrate most things that the ASU-85 may encounter. Anything that cannot be penetrated by the APBC shell will almost certainly be penetrable by the 3BK7 HEAT-FS round. Boasting 300 mm of penetration, it is capable of punching straight through a Tiger II's upper glacis and does not lose penetration over distance. However, it suffers the usual drawbacks of HEAT rounds (cannot go through obstacles like trees or fences) and is significantly less lethal than the APBC shell. The muzzle velocity is also lower, which can complicate aiming at long ranges.

Usage in battles

The ASU-85 is a veritable glass cannon that relies on stealth and/or distance in order to survive on the battlefield. It is very vulnerable if caught in the open, especially to planes due to the very weak roof armour. The 85 mm gun is capable of handling almost any tank likely to be encountered by the ASU-85. Unfortunately, the ASU-85 lacks the mobility of its predecessor, the ASU-57, and thus has to adopt a more passive playstyle. The stock APBC round is excellent for ambushes, which tend to involve a lot of side shots where the lethality of the explosive filler is valuable, especially with the long reload time of the gun. The HEAT-FS round is better suited for medium/long-range fighting, since it does not lose penetration over distance.

The ASU-85 has a rather unorthodox method of using its smoke screen. Unlike most vehicles, which use smoke shells, singular canisters, or canister clusters, the ASU-85 uses two large drum like structures at the rear. When deployed, these will drop away, so it is relatively easy to tell from close range whether or not an ASU-85 has smoke or not, and how many it has. Due to the orientation of the drums, the smoke screen will actually form behind the tank and take about 2-3 seconds to fully envelope the assault gun.

Common opponent weakspots:

  • Tiger II (P), (H), 105 mm: Turret cheeks. HEAT-FS can penetrate the hull front.
  • Panther II: APBC can penetrate the turret face. HEAT-FS can penetrate the hull front.
  • T29: Lower glacis. There are also weakspots in the gun mantlet, but they may be hard to hit at anything but close range.
  • Caernavron: Turret ring and lower glacis.
  • A39 Tortoise: Area surrounding the hull machine gun port.
  • T95: Cupolas may be penetrated but do not trigger the explosive filler of AP rounds.
  • Jagdtiger: HEAT-FS can penetrate the hull front and superstructure.
