ISU 152 BL 10

History

Samokhodnaya Ustanovka na baze tanka IS s orudiyem kalibra 152mm, meaning "IS tank based self-propelled installation with 152mm caliber gun") is a Soviet self-propelled gun developed and used during World War II. It was unofficially nicknamed zveroboy "beast killer" in response to several large German tanks and guns coming into service, including Tigers and Panthers.

Since the ISU-152's gun was mounted in a casemate, aiming it was awkward, and had to be done by repositioning the entire vehicle using the tracks. Therefore, it was used as mobile artillery to support more mobile infantry and armor attacks. It continued service into the 1970s and was used in several campaigns and countries.

The beginnings of the ISU-152 came on January 24, 1943, when the first prototype of the SU-152 was unveiled. This was a fully enclosed 152mm gun-howitzer on the KV-1S tank chassis. In mid-1944, the Red Army recognized that it might need tanks that could consistently and reliably destroy the Wehrmacht’s most well-armored tanks.

The Red Army fielded few tanks that could destroy the King Tiger, Elefant, and Jagdtiger reliably from medium-long ranges. Although it is true that the ISU-122, ISU-122s, ISU-152, and IS-2 were capable of destroying German heavy tanks, their combat results were not consistent enough.

As a result, starting in June of 1944, five “BM” (“High Power” guns were developed for the ISU chassis. The resulting vehicles were: Object 243 (ISU-122-1 with the 122mm BL-9 gun), Object 246 (ISU-152-1 with the 152mm BL-8 gun), Object 247 (ISU-152-2 with the 152mm BL-10 gun), Object 250 (ISU-130 with the 130mm S-26 gun), and Object 251 (ISU-122-3 with the 122mm S-26-1 gun). More gun projects were being developed at this time, but no others appeared to be mounted onto a chassis.

Object 247 (ISU-152-2) with the 152 mm BL-10. This vehicle is distinguishable by the length of its barrel (it was slightly shorter compared to the BL-8), its muzzle brake, and its altered gun replicator.

The Object 247 fitted the 152 mm BL-10 gun, an improvement of the BL-8. This vehicle can be distinguished by its muzzle brake and slightly altered gun mantlet, whereby the rectangular tip of the gun replicating system had been angled, unlike the original ISU mantlet.

• It could penetrate 205 mm of armor from 1000 m.
• The gun had a muzzle velocity of 851 m/s with a 43.56 kg HE shell.
• It had a maximum range of 17,000 m.
• It could carry 20 HE shells.
• Testing revealed that barrel integrity and angle of horizontal guidance were poor.
• It was eventually deemed that there was no need for this work to continue, mostly because the war was over, and there was no need to combat heavily armored German vehicles.

Consider also, that whilst the barrel length was a little shorter than the BL-8, it, too, would still suffer from maneuverability issues as a result.

Control

• Use Trim to move forward and backward
• Use Roll to Traversing
• Use Pitch to Elevate cannon
• Press AG1 to activate lights

Hope you enjoy my works

Note : This is my first replica build, i am sorry if i miss some details, please tell me what do you think of this build so i can fix my further builds :)
