The '''ASU-85 (Авиадесантная самоходная установка, АСУ-85)''' was a Cold War-era Soviet-designed airborne self-propelled gun. It began to replace the open-topped [[ASU-57]] in service in 1959. Beginning in 1969, it was superseded by the BMD-1. It was designed to replace older designs such as the ASU-57 for use by the Vozdushno-Desantnye Voyska (VDV). Its design was lengthy and intricate, and it took nearly ten years to complete due to the demanding demands of getting the vehicle airborne. The ASU-85 saw duty as late as the Soviet-Afghan War, but it was far from widespread. The ASU-85 was based on the [[PT-76 (Family)|PT-76 light amphibious tank family]] chassis, however, it lacked amphibious characteristics and was powered by a different engine. The vehicle was divided into three compartments: the driver's compartment at the front, the combat compartment in the centre, and the engine compartment in the back. The ASU-85 was utilized in airborne missions by the Soviet Airborne Forces. With minimal anti-tank capability, its primary function was light infantry support or assault fortifications. The ASU-85 was only exported to two other Warsaw Pact countries: East Germany and Poland. NATO first noticed it in 1962, and it was frequently utilized by Soviet and Polish airborne units.

The '''{{specs|name}}''' is a Rank {[specs|rank}} Russian tank destroyer {{BR1}}. It was introduced in [[Update 1.59 "Flaming Arrows"]]. It's low profile and extremely potent gun makes it a wonderful contender in the 6.7 BR range. However, the lack of armour makes it hard use this vehicle in open environments. Everything will become easier when you unlock the HEAT-FS shell with 300 mm penetration at any distance.
 
  
The [[ASU|ASU]]-85 has a rather unorthodox method of using it's 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's relatively easy to tell from close range whether or not an ASU-85 has smoke or not, and how many it has.
+
Introduced in [[Update 1.59 "Flaming Arrows"]], the ASU-85 is a unique vehicle that survives on the battlefield through stealth. It is particularly vulnerable if caught in the open due to the very thin roof armour, especially against planes. The armament can deal with almost any tank that the ASU-85 is likely to encounter. Unfortunately, the ASU-85 lacks the mobility of its forefather, the ASU-57, and must play more passively. On city maps, where engagements are typically close-range, this could be a problem. Overall, the ASU-85 is a situational vehicle that excels on large maps and circumstances where the terrain allows for stealth ambush but struggles in close-quarters combat.
 
 
Be wary of the this method of deployment, as 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 you.

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. Angling is useless in this tank, since thin armour parts get overmatched by high calibre shells and they just ignore ricochet chance completely. If it is necessary to give the enemy something to fire at, it is possible to take only half of the shells and then present the left side to the enemy, as it will have less ammo racks, though it is still likely the entire tank will be obliterated anyway.
 +
 
 +
The tank itself is very short and can even bully tanks like the [[M4A3 (76) W]] by standing next to them, as it will only be able to aim at the autobounce zone on top of the ASU-85 and will likely miss. In the case if the tank it stands next to explodes, the ASU-85 will also suffer overpressure damage and often lose crew, so moderate levels of "vitality" crew skill are needed to survive when doing this.
 +
 
 +
The ASU-85 is also somewhat vulnerable to aircraft strafing, particularly if they attack from the top or with rockets.

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 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 recoil of a gun throws the tank around, especially if it is fired sideways, sometimes kicking the tank backwards up to 5-10 m.

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, very similarly to APDS. 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 stock shell is good. 230mm penetration is enough for weak spots in Rank IV. It is recommended to get the HEAT-FS shell as soon as possible for the ultimate 300 mm penetration for the vehicle. Beware of any incoming fire however, the armour is weak at only 45 mm thickest at the front. The mobility is mediocre, remember to cover flanks
+
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 5 seconds to fully envelope the assault gun.
 +
 
 +
The smokes screens themselves are very thin and allow ASU-85 to see through them with sniper scope and attack. In arcade mode, ASU-85 can use smoke screen to disable aim assist and spotting for enemy vehicles while still being able to track their position with scouting, which works well with its ability to bounce poorly aimed shots. The APDS-like APHE and HEAT-FS also help with fighting with aim assist off, which makes it a viable trick, though it will not help if enemy already took aim at ASU-85 and is just waiting for reload to finish.
  
*'''Sniper''': This tank doesn't surpass other snipers in Rank IV, due to the lack of armour. Utilize all possible mechanics to aid in acquiring and ranging the targets, especially the binoculars and range finder modification.
+
Heavily armored opponent's weakspots:
*'''Ambush''': Find somewhere in the map that you feel most of the fight will happen there, find a good view with nice covers at there. Or just sitting in some bushes near the flanking routes.
 
  
Some enemies to be concerned of:
+
* Tiger II [[Tiger II (P)|(P)]]/[[Tiger II (H)|(H)]]: Turret cheeks are penetrable by APCBC even at 1.2km. Shoot the left cheek to kill all turret crew and wound the hull crew.  
* Tiger II [[Pz.Kpfw. VI Ausf. B (P)|(P)]], [[Pz.Kpfw. VI Ausf. B (H)|(H)]], [[Pz.Kpfw._VI_Ausf._B_mit_10,5cm_KwK_L/68|105 mm]]: Shoot at the turret cheeks (only front weakspot). If the HEAT shell is available, shoot the HEAT straight into their hull.
+
* T26E5: Cupola, turret ring and hull MG port remain weakspots even up to 2km with APCBC.
* [[Panther II]]: Use HEAT against hull if it is at a close range and is looking right at the vehicle. In a longer distance, try for the lower glacis and the turret cheeks
+
* T26E1-1: Hull MG port and upper section of lower glacis remain penetrable with APCBC up to 2km.
* [[Heavy Tank T29|T29]]: Shoot the lower glacis if engaging it frontally. There are a few weak points in the front turret as well, look for them.
+
* T34: Hull MG port, lower glacis and cupola penetrable at 1km. MG port and most of the lower glacis remain penetrable at 2km.
* [[FV 221 Caernarvon|Caernavron]]: Fire at the turret ring and lower glacis.
+
* [[T29]]: Lower glacis. There are also weakspots in the gun mantlet, but they may be hard to hit at anything but close range.
* [[A39 Tortoise]]: Aim towards the machine gun port on the left side, there will be a weak point present.
+
* [[Caernarvon]]: Turret ring and lower glacis.
* [[105mm Gun Motor Carriage T95|T95]]: Aim towards one of the two commander cupolas on the roof. Try to aim at its side so that the penetrating shell can detonate inside and severely damage the crew.
+
* [[Tortoise]]: Area surrounding the hull machine gun port.
* [[Jagdpanzer VI Jagdtiger|Jagdtiger]]: A well-protected armoured beast. If caught in the front, try to engage it with HEAT shells, preferably at the lower glacis.
+
* [[T95]]: Cupolas may be penetrated but will not generate enough spall to reliably kill more than 1 crew member. HEAT-FS also does not seem to be capable of consistently disabling more than 1 crew member. Suggest breaking their gun and running away to flank them. The upper section of the T95's sides are vulnerable to APCBC even at 1km.
* [[Medium Tank M26E1|M26E1]]: Though dangerous towards the ASU, its armour is similar to the [[Medium Tank M26 Pershing|M26 Pershing]] and could be easily taken out by a good shot on the front hull.
+
* [[Jagdtiger]]: APCBC can penetrate lower glacis and hull MG port up to 800m. 1-shot kill is in theory possible with HEAT-FS, but you will need to aim at the left or right cheeks to hit the ammo.

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-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.

Description

The ASU-85 (Авиадесантная самоходная установка, АСУ-85) was a Cold War-era Soviet-designed airborne self-propelled gun. It began to replace the open-topped ASU-57 in service in 1959. Beginning in 1969, it was superseded by the BMD-1. It was designed to replace older designs such as the ASU-57 for use by the Vozdushno-Desantnye Voyska (VDV). Its design was lengthy and intricate, and it took nearly ten years to complete due to the demanding demands of getting the vehicle airborne. The ASU-85 saw duty as late as the Soviet-Afghan War, but it was far from widespread. The ASU-85 was based on the PT-76 light amphibious tank family chassis, however, it lacked amphibious characteristics and was powered by a different engine. The vehicle was divided into three compartments: the driver's compartment at the front, the combat compartment in the centre, and the engine compartment in the back. The ASU-85 was utilized in airborne missions by the Soviet Airborne Forces. With minimal anti-tank capability, its primary function was light infantry support or assault fortifications. The ASU-85 was only exported to two other Warsaw Pact countries: East Germany and Poland. NATO first noticed it in 1962, and it was frequently utilized by Soviet and Polish airborne units.

Introduced in Update 1.59 "Flaming Arrows", the ASU-85 is a unique vehicle that survives on the battlefield through stealth. It is particularly vulnerable if caught in the open due to the very thin roof armour, especially against planes. The armament can deal with almost any tank that the ASU-85 is likely to encounter. Unfortunately, the ASU-85 lacks the mobility of its forefather, the ASU-57, and must play more passively. On city maps, where engagements are typically close-range, this could be a problem. Overall, the ASU-85 is a situational vehicle that excels on large maps and circumstances where the terrain allows for stealth ambush but struggles in close-quarters combat.

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. Angling is useless in this tank, since thin armour parts get overmatched by high calibre shells and they just ignore ricochet chance completely. If it is necessary to give the enemy something to fire at, it is possible to take only half of the shells and then present the left side to the enemy, as it will have less ammo racks, though it is still likely the entire tank will be obliterated anyway.

The tank itself is very short and can even bully tanks like the M4A3 (76) W by standing next to them, as it will only be able to aim at the autobounce zone on top of the ASU-85 and will likely miss. In the case if the tank it stands next to explodes, the ASU-85 will also suffer overpressure damage and often lose crew, so moderate levels of "vitality" crew skill are needed to survive when doing this.

The ASU-85 is also somewhat vulnerable to aircraft strafing, particularly if they attack from the top or with rockets.

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.

Note that the ASU-85 is not amphibious, unlike the PT-76B it is based on.

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 recoil of a gun throws the tank around, especially if it is fired sideways, sometimes kicking the tank backwards up to 5-10 m.

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, very similarly to APDS. 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 5 seconds to fully envelope the assault gun.

The smokes screens themselves are very thin and allow ASU-85 to see through them with sniper scope and attack. In arcade mode, ASU-85 can use smoke screen to disable aim assist and spotting for enemy vehicles while still being able to track their position with scouting, which works well with its ability to bounce poorly aimed shots. The APDS-like APHE and HEAT-FS also help with fighting with aim assist off, which makes it a viable trick, though it will not help if enemy already took aim at ASU-85 and is just waiting for reload to finish.

Heavily armored opponent's weakspots:

  • Tiger II (P)/(H): Turret cheeks are penetrable by APCBC even at 1.2km. Shoot the left cheek to kill all turret crew and wound the hull crew.
  • T26E5: Cupola, turret ring and hull MG port remain weakspots even up to 2km with APCBC.
  • T26E1-1: Hull MG port and upper section of lower glacis remain penetrable with APCBC up to 2km.
  • T34: Hull MG port, lower glacis and cupola penetrable at 1km. MG port and most of the lower glacis remain penetrable at 2km.
  • T29: Lower glacis. There are also weakspots in the gun mantlet, but they may be hard to hit at anything but close range.
  • Caernarvon: Turret ring and lower glacis.
  • Tortoise: Area surrounding the hull machine gun port.
  • T95: Cupolas may be penetrated but will not generate enough spall to reliably kill more than 1 crew member. HEAT-FS also does not seem to be capable of consistently disabling more than 1 crew member. Suggest breaking their gun and running away to flank them. The upper section of the T95's sides are vulnerable to APCBC even at 1km.
  • Jagdtiger: APCBC can penetrate lower glacis and hull MG port up to 800m. 1-shot kill is in theory possible with HEAT-FS, but you will need to aim at the left or right cheeks to hit the ammo.

Pros and cons

Pros:

  • Excellent 85 mm gun - higher penetration and muzzle velocity than the 100 mm D-10T found on the T-54s
  • Competitive stock APBC round with explosive filler
  • Access to HEAT-FS with 300 mm of penetration
  • Tiny profile
  • Access to a coaxial machine gun
  • Access to night vision devices

Cons:

  • Slow gun elevation and traverse
  • Slow reload for an 85 mm gun
  • Cannon recoil is so strong it throws the tank around and will not only mess with tanks aim but kick the user off a cliff if they are not careful
  • Lightly armoured everywhere besides the front, vulnerable to aircraft strafing, angling even just slightly will expose the extremely weak side armor to vehicles with APCBC shells
  • Poor reverse speed
  • Mediocre mobility and low maximum speed, considering the light armour
  • Poor gun depression

History

Development

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-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 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.

Usage

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 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. The ASU-85 are still in service in the Vietnamese military, with interests on improving their technical performances in early 2016.[1]

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 "Shilka" anti-aircraft system.
