ISU-152 - Questions, Information, Gameplay

You´re welcome!

 

Concerning your fuel trailer, possibly yes - as stated above, a round fired at 30° angle might bounce. And a fuel tank isn´t that thick-walled at all, maybe it´s belly was penetrated (by debris?) and ignited by a spark or tracer. We´ll never know, but as a consenus we should state that (battle) tanks weren´t killed by Ma Deuce ;)s

ISU-152r.jpg

 

"The streets of Vienna, fleeing in all directions from the central square, were too narrow. Beautiful houses with Venetian windows loomed at both sides. The shots of the high-caliber self-propelled gun thundered and sharply wavered the air. One half of house’s floors with the enemy anti-tank gun and its gunners fell to the ground. A powerful air wave after the shot broke up the glass in windows near the ISU-152 and our location. Heavy glass fragments rained down on the heads of “spectators” and as a result 10 people were wounded in backs and hands and 2 more broke their collarbones. Luckily tank crews and troopers wore helmets and their heads remained safe."

Early Model:
The ISU-152 marks its beginning on January 24,1943. This was the moment of appearance of the first
fighting vehicle of this family.

It was designated Object 236 (Объект 236), using the same concept as the SU-152. The Object 236 was completed in Factory No. 100 in Chelyabinsk, and on the same day, January 24, underwent trials on the Chebarkulski artillery range, 107 km from Chelyabinsk.

 

By February 7, 1943 the trials were over, passed with success.

On February 14 the vehicle was adopted and put on production under the KV-14 (КВ-14) designation.

 

In April 1943 was ordered KV-14 to be henceforth designated SU-152 (СУ-152). In time, the combat performance of SU-152, based on the KV-1S tank, made necessary the modernisation of the vehicle, using the new IS tank as a base.

 

On May 25, 1943, shortly after deployment, the administration of Factory No. 100 ordered the beginning of the SU-152 modernization, which included an increase of the armour protection and other improvements.

 

The development began in July 1943, under the supervision of Joseph Yakovlevich Kotin (the chief designer of Soviet heavy tanks) and G. N. Moskvin as the main designer, and in about a month the first modernized variant was ready. It was designated IS-152 (ИС-152). It underwent factory trials in September 1943, revealing a large number of different deficiencies, which sent it back for further improvement.

 

In October 1943 a second (different) modernized variant was ready, designated Object 241 (Объект 241). It was an improvement over the IS-152.

The factory trials began the same month, followed by state trials on the Gorohovetskom test range.

On November 6, 1943, an order was issued for adoption of this variant, under the ISU-152 (ИСУ-152) designation, and in December its production began at the Chelyabinsk Kirovsk Plant, replacing the SU-152.



Late Model:
One prototype, developed in 1944. In April 1944, in attempt to increase the firepower of ISU-152, a high-power variant of the self-propelled gun was developed in Factory No. 100, designated ISU-152BM (ИСУ-152БМ), sometimes referred to as ISU-152BM-1 or ISU-152-1.

 

The factory designation was Object 246 (Объект 246). The "BM" ("БМ") in the designation stands for "High Powered" ("Большой Мощности"). The main purpose of the ISU-152BM was the fight against heavily armoured tank destroyers such as the Elefant and the Jagdtiger.

It was armed with the 152.4 mm BL-8 (БЛ-8) long barrel gun, which unlike the ISU-152's gun wasn't a gun-howitzer.

The gun had a maximum range of 18,500 metres, with the 43.56 kg high-explosive shell which had a muzzle velocity of 880 m/s.

 

The overall length of the gun was over 8 metres, with a barrel length of 7620 mm (50 calibers).

The armour-piercing round, weighing 48.78 kg, had a muzzle velocity of 850 m/s.

During test firing at armour plates with different thickness, the ISU-152BM had successfully penetrated a maximum of 203 mm of RHA at 90° at ranges of up to 2000 metres.

However, during the trials, July 1944, the gun showed some deficiencies such as being difficult to operate by the crew, unreliable work of the muzzle brake and the breech
block, and unsatisfactory performance of the shells.

 

In addition, the gun, reaching out too far, was limiting the maneuverability of the fighting vehicle. The self-propelled gun carried 21 rounds of two piece (shell and charge) ammunition, and had a rate of fire of 2 rounds/min.

 

It used the engine, transmission, running gear and electric equipment of the ISU-122. In August 1944 the BL-8 gun was replaced with the improved 152.4 mm BL-10 (БЛ-10) long barrel gun, with a slightly shorter barrel of 7392 mm (48.5 calibers).

 

The self-propelled gun was designated ISU-152-2 (ИСУ-152-2). The factory designation was Object 247 (Объект 247). The fighting vehicle was also equipped with external fuel tanks.

 

The gun had a modified muzzle brake and a semi-automatic breech block it had a rate of fire of 3 rounds/min.

The BL-10 had a maximum range of 18,000 metres, with the 43.56 kg high-explosive shell.

In December 1944 the ISU-152-2 underwent trials, revealing the barrel strength and the angle of horizontal guidance were unsatisfactory.

 

The gun was sent for further improvement, but it wasn't completed before the war ended.

 

The fighting vehicle was never adopted. After the war, the final and most improved, third modification of ISU-152-2 was completed. The gun had a maximum range of 19,500 metres, using a 48.5 kg high-explosive shell with a muzzle velocity of 880 m/s.

Heavy Tank Destroyer Role:

 

The ISU-152 could also operate as an effective heavy tank destroyer though it was not designed for the role, the vehicle inherited the nickname Zveroboy ("beast killer") from its predecessor, the SU-152, for its rare ability to reliably kill the best protected German fighting vehicles; the Panther tank, the Tiger and Tiger B tanks, and even the Elefant and Jagdtiger tank destroyers.

 

The sheer weight of the 152.4 mm shells resulted in an extremely low rate of fire, only one to three rounds per minute, and were not as accurate at long range as high-velocity antitank guns.
However, the massive blast effect from the heavy high-explosive warhead was capable of blowing the turret completely off a Tiger tank.

A direct hit usually destroyed or damaged the target's tracks and suspension, immobilizing i while the low-velocity 152mm shell did not generally penetrate heavy armor,
it frequently killed or severely wounded the crew through spalling (splintering) inside the hull as well as injuries caused by blast concussion.

 

Surviving crew were often left with an immobilized vehicle which had to be hurriedly abandoned before being destroyed.

For anti-tank operations following the Battle of Kursk, armour-piercing ammunition was developed, with an eye towards giving the howitzer a more traditional anti-tank capability.

 

However, these rounds were expensive, in short supply, and only moderately more effective than the standard non-penetrating high-
explosive round.

 

As a howitzer the ML-20S exchanged velocity and accuracy for throw weight and distance, and was not intended to compete with true anti-tank guns. Sometimes the concrete-piercing ammunition was used for the anti-tank role.

 

A primitive shaped charge ammunition, with a 27.44 kg shell, was also developed. It had a maximum
penetration of 250 mm of RHA at 90°, but it was not used during the war.

Heavy Artillery Role:

 

As a heavy assault gun, the ISU-152 was an extremely valuable weapon in urban combat operations such as the assaults on Berlin, Budapest and Königsberg.

The vehicle's excellent armour protection finally provided the 152.4 mm platform with good protection from most German anti-tank guns, allowing it to advance into the face of direct anti-tank fire, while the huge low velocity high-explosive rounds were excellent at blasting open even the most heavily fortified and reinforced enemy strongpoints.

 

Such actions would be much more dangerous and much less effective for a conventional towed artillery piece, with their high crew exposure and low mobility, or even a tank, with their smaller main guns.

 

When supporting tanks, the usual tactics of the ISU-152 were to be used in the second line of the attack order, 100 to 200 metres behind the attacking tanks, which were usually IS tanks with equal mobility.

Armor:

 

The ISU-152's 90 mm of sloped frontal armor, in contrast to the SU-152's 65 mm, provided excellent frontal protection from the 75mm KwK 40 gun of the ubiquitous Panzer IV and StuG family at all but the closest ranges, while also forcing the original Tiger I, with its vaunted 88mm KwK 36 gun, to close to medium ranges in order to successfully penetrate the vehicle, negating its traditional long range superiority.

Speed:

 

37 km/h (23 mph) on road 15-20 km/h cross terrain 40 km/h (on a road) (ISU-152 model 1945, ISU-15 ISU-152M)

 

Most information taken from wikipedia as you know Soviet Tech is quite secret.

So you just copied and pasted its stats?

Can we get a link, your post is oddly layed out.

"its rare ability to reliably kill the best protected" Aren't "rare" and "reliably", kinda.. conflicting? Just saying.

 

Anyway, it will/would probably make a nice SPG/TD. But I still think the Ferdinand will own all.

I believe he is saying that it was one of the only vehicles (hence rare) to be able to frequently(Hence reliably) penetrate the German heavies.

Fixed the formatting.

 

And yes mainly copied and pasted doesn't matter though because the Russian Army section is lacking in tanks.

ISUs didn't penetrate, they just had such a large HE charge that turrets fall off.

From my experience in WoT, tank destroyers are very hard tanks to play with.

These types of tanks need the most team support. Which lacks in every online game, because they lack of having a turret.

 

Just see how many protection our bombers are getting in this game.

The ISU-152 will be best in a squad, have someone take the enemies interest and you flank the guy and or get into a good firing solution and one shot the enemy or damage it critically.

That's world of tanks tactics... with the ISU-152 just like with the Sturmtiger I believe the best tactic would be firing at the maximum range of the gun with HE ammo. This would be aided by other people spotting for you.

In real life the ISU-152 stayed 200 meters behind IS-2 tanks.

Well 1 thing I find funny about Russian tanks, in the beginning of WW2 Russian tanks didn't had any radios and they used flags to communicate with each other.

Two problems there Klaus.

 

The BL-10 was an utter and complete failure of a gun, rendering the ISU-152 incapable of maneuvering because it literally tipped it over from it's weight.

 

The ISU-152 was incapable of blowing the turret OFF a Tiger, but it could gut the turret. Tiger turrets were not gravity mounted like every other tank, they were bolted in, and they didn't fly off.

Well they could fly off if you touched off the ammo inside the turret and the tank but that's classed as a secondary explosion.

Well in WoT the maps aren't really that big.

Here we will have alot bigger maps than that, so you can fire from like 2km instead of 100 meters.

Well good luck with firing the howitzer 152mm from 2km distance. You will miss all your shots because it's a close range barrel, terrible accuracy

I know but here you will actually have a chance to stay hidden when you fire.

I've never heard of a Tiger ever having it's turret blown off. Ever. For any reason.

 

When I say they were bolted down, I mean that a 16" round wouldn't tear it off, just gut it and leave nothing but the base.

Russians used black powder as a propellant... Ever seen a musket go off? Yeah... make that musket 20x larger and you get a Russian 152mm cannon.
