can say, finally reached! No, there is still a bunch of stories about other tanks, SAU and ZSU, but it is something! ISU-152. "Deerslayer". Although I would say otherwise.
If literary, it is an instrument at the time of Armageddon. quintessence of death, slowly and calmly. You can hysteria and trying to knock out her. You are welcome, as the saying goes. success. You can try to escape, using speed. No problem. The projectile is still faster.
The whole shape of the self-propelled means one thing principle. the very: «We slowly descend the hill, slowly crawling River, and you hana».
Say - too much emotion. I agree. But even modern "MSTA", which will be discussed a bit later, It does not cause such feelings. "MSTA" modern, such refined, Well I do not know, how to say. "Deerslayer" - a concentrated brutal, especially when you begin to understand its essence.
And the essence is simple. We took the most powerful howitzer-gun 152mm (ML-20, why waste time on trifles?) and scalded her hulls. And hoisted it on a tank chassis.
First signs called SU-152. Swallow weighed 45,5 tons and was made on the KV-1S tank chassis. Happened. After removal of the HF-1c were produced with production 670 these heavy assault guns, that could (partially) perform the role of ACS.
Swallow successfully Shatala tower "Tigers" and "Panthers" on the Kursk Bulge, and, if not downright weak chassis HF, probably, released to continue.
But intelligence reported about the developments in the new German heavy tanks (that were true) and the decision was made in a very Soviet-style. Higher, farther, stronger or whatever.
ISU-152 - this is just the very thing. Base Isa, from him and the letter "I" in the title. We had to reduce the inclination board sheets due to smaller width IP of the tank as compared with a HF 250 to 150 the vertical, and the slope of the rear plate to eliminate completely.
thickness of armor at the same time increased with 75 to 90 mm at the frontal sheet cuttings and 60 to 75 mm for board. Mask with guns increased 60 mm, to 100 mm.
In this image, we can estimate the thickness of armor. loosen the purse strings
Huge advantage of the ISU-152 as compared to the Su-152 was the installation of the forced ventilation. When opening the shutter after firing of thick powder smoke, similar to the consistency of sour cream, slowly spread over the floor of the crew compartment crew members ... SU-122 often during combat often lose consciousness from accumulated powder gases after discharging half ammunition.
152-mm howitzer-gun ML-20C obr.1937 / 43 dd. mounted in a molded frame, played the role of the upper machine guns, and protects the cast armored mask, Same, that of the SU-152.
In contrast to the field howitzer, on ISU-152 were hinged tray mounted to facilitate loading and additional thrust to the trigger, Handle flywheels lifting and turning mechanisms were the gunner on the left along the machine, pins have been brought forward for a natural balancing.
telescopic sight ST-10 is used for direct fire, for firing indirect fire served as a panorama of Hertz with extension, the lens is out of the cabin through the open hatch near the top left.
Range direct fire was 3 800 m, the greatest - 6 200 m. rate - 2-3 shots per minute.
The gun had electrical and mechanical (manual) downs. Trigger electric trigger was on the handle of the lifting mechanism of the flywheel. The instruments of the first releases was used only manual descent.
Ammunition consisted of 21 shots separate the gland loading with armor-piercing tracer shells ostrogolovymi BR-540, high-explosive cannon and howitzer grenades steel PF-540 and PF-530, howitzer fragmentation grenade of iron stalistogo 0-530A.
Armor-piercing tracers were in a niche of the conning tower on the left side in the special framework, high-explosive grenades - there, shells with warheads in a niche in special felling framework and laying homutikovoy. Part of the sleeves with warheads placed on the bottom under the instrument.
Initial velocity armor-piercing projectile with a mass 48,78 kg was 600 m / s, at a distance 1000 he directs m thick armor 123 mm.
On a part of cars in October 1944 years on a rotating commander's hatch was the pursuit mounted anti-aircraft turret with 12.7 mm machine gun DSK. Ammunition to the gun was 250 rounds.
Besides, as a personal weapon of the crew there were two submachine gun PCA (later PPP), 20 cartridges and discs 20 hand grenades F-1.
In the spring 1944 year heavy self-propelled artillery regiments, Armed SU-152, perevooružalisʹ ustanovkami ISU-152 and ISU-122. They were transferred to the new states and all awarded the title of Guards. By the end of the war it was formed 56 these regiments, each had 21 Machine ISU-152 and ISU-122 (or both, and others, such shelves called mixed).
What else can you show?
From my point of view, the most miserable person in the crew - a driver. This plan in its place. Over there, at the bottom, where the instrument panel ... It is very difficult to get, even harder to get, plus the place is not very much.
devices for at least. no speedometer, but here and there is no special rate. And not much need, basically.
Hatches crew all equipped with periscopes.
There were personal lighting devices for mehvoda.
Summing a result of ISU-152, can say, that the self-propelled gun is a successful example of universal heavy self-propelled artillery system. The best proof of this - its life, which lasted until the 70s of the last century. And do not participate in a local conflict.
Well armored monster with a gun, against which there was no time armor, but still robust and unpretentious - what more could you want?
It was, of course, and disadvantages. The most significant, I would call a small ammunition. Total 20 shots. large shells, Besides, It was the cause of a long loading time of ammunition, about 40 minutes. Well, wimps in the gunners did not take, Nevertheless, Silushka required.
Another minus - Optics. Well, it has already become a classic. Telescopic sight ST-10 has been calibrated for shooting at a distance of up to 900 m, although the weapon allows you to fire point-blank range at a distance of up to 3,5 km. Yes, It was a panoramic sight, but there is just the opposite, long range telescopic needed.
I read in memoirs, that in the 45th year of our artillerymen practiced this method, like firing at one point several ACS. In this scenario, the lack of accuracy is somewhat compensated.
Contact with high-explosive projectile near the target often infuriated her down without even breaking through the armor. The blast wave and debris could damage any tanks and assault guns gun, chassis, sights.
Shooting high-explosive shells ISU-152 was on armored vehicles is quite commonplace, because the ammunition 13 shots from 20 were just high-explosive. Rest 7 They were armor-piercing (or, much less, - betonoboynymi). but again, 152-RP-mm projectile was enough, to make balls of.
Did, that the most fun in our history? Compare ISU-152 really do not have anyone. I wanted to spend a couple of analogies, but does. If we take the TTC criteria, arms and application, it must be admitted: there was no analogues.
There were large-caliber guns (150-155-mm) based on self-propelled the Germans and Americans. But that «Hummel» Germans, M12 that the Americans were very lightly armored howitzer on the basis of medium tanks. And in any time were neither anti-ACS, or assault guns.
ACS "Hummel"
SAU GMC M12
Heavy Fighter "jagdpanther" tanks? Yes, similar in performance characteristics, but purely anti-machine.
Were the Germans assault guns, who could fight with tanks. StuG III и StuG IV. But both were significantly easier self-propelled ISU-152 to arm and weight, and weaker armored.
SAU StuPz IV «Brummbär» ... Caliber yes, the rest - no.
Self-propelled gun was also lighter in weight, and its short-howitzer 150 mm caliber weapon was, rather, mortar overgrown, than full gun.
Yagdtigr. Like the truth.
gun, 128 mm and booking at the level of the ISU-152, and occasionally abruptly. But the weight is almost 2 times more, than that of our self-propelled. Plus again, clear protivotankist.
AND, the main thing. amount. That is the, that could make a real contribution. 79 "Jagdtiger" and 340 "Brumbarov" - compared to more than three thousand only ISU-152 ...
best? best. Can, not the, here with ISU-122 will need to be compared, but nonetheless.
