StuG III Ausf.G

描述

This self-propelled assault gun Sturmgeschütz III Ausführung G was armed with 75 mm StuK 40 L/48 gun. Ausf.G was one of the last modifications, but the most numerous: 7800 SPG in total since December 1942 till April 1945. Compared to the previous one, it had a longer gun barrel (L/48 instead of L/43) and additional armour sheets installed in the hull and cabin front. The SPG modeled in our sim was built at MIAG factory using the Pz.Kpfw. Ausf.M chassis produced by MAN factory.

The most apparent visual difference was the addition of side armor plates, “Schürzen”, which were attached to the hull sides. They were added mainly to protect the tank from massed AT rifle fire which was dangerous for thinner armored sides. Not being able to stop an AP bullet, this additional armour destabilized it or caused its fragmentation before it could hit the main armored hull.

The tank could be equipped with six mortars mounted on the turret and designed to shoot smoke grenades at a distance of about 80 meters.

The long-barrelled 75 mm gun can reliably engage Soviet tanks at distances up to 1 km. However, the artillery periscopic gunsight was less convenient for quick direct firing than telescopic gunsights installed on tanks.

Late StuG III modifications were equipped by infantry MG34 machinegun stored in the fighting compartment. To fire it, the loader had to get out of his hatch, raise the armored shield and set the machinegun up in one of the two positions - for firing at air or ground targets. Six one-shot smoke mortars could be also installed.

修改

穿甲榴弹

7，5 cm Pzgr.39

炮弹上装有爆炸弹头。

对抗装甲目标效果好。击穿时对目标内部造成比穿甲弹（AP）更大伤害，但是榴弹（HE）装药可能过早引爆（比如用于对抗间隙装甲板时）

质量 6.8 kg，炸药质量 18 g.

当从7.5cm Stu K 40 L/48火炮发射时：
炮口初速：750 m/s，近距离装甲穿深 117 mm
500m时：装甲穿深 104mm，速度 691 m/s，下坠高度 2.4m
1000m时：装甲穿深 92mm，速度 636 m/s，下坠高度 10.0m
2000m时：装甲穿深 72mm，速度 537 m/s，下坠高度 44.8m

榴弹

7，5 cm SprGr.34

对抗软目标、无装甲和轻装甲目标效果好。

质量 5.74 kg，炸药质量 660 g.

直接命中装甲穿深 20mm，对轻型车辆有效杀伤距离3m

当从7.5cm Stu K 40 L/48火炮发射时：
炮口初速：550 m/s
500m时：速度 509 m/s，下坠高度 4.5m
1000m时：速度 473 m/s，下坠高度 18.5m
2000m时：速度 405 m/s，下坠高度 80.9m 

破甲弹

7，5 cm Gr.38 HL/С

破甲弹有成型高爆聚能战斗部装药

它们的穿甲能力不会随射程的增加而降低，但准确性却会降低，因为弹速较低，而类似的动能穿甲弹通常在近距离具有较高的装甲穿透能力。

质量4.57 kg，炸药质量530 g，装甲穿深 104 mm

当从7.5cm Stu K 40 L/48火炮发射时：
炮口初速：450 m/s
500m时：速度 328 m/s，下坠高度 7.8m
1000m时：速度 278 m/s，下坠高度 38.1m
2000m时：速度 244 m/s，下坠高度 200.4m 

次口径穿甲弹

7，5 cm Pzgr.40

装有次口径穿甲弹芯的炮弹。在近距离对抗重装甲目标效果好。

7.5cm Pzgr.40是一种复合弹药 - 硬（钨合金）弹芯在由较软的钢组成的弹体里（用于炮管内密封）

质量：4.1 kg，弹芯口径28 mm

当从7.5cm Stu K 40 L/48火炮发射时：
炮口初速：930 m/s，近距离装甲穿深 150 mm
500m时：装甲穿深 128mm，速度 832 m/s，下坠高度 1.6m
1000m时：装甲穿深 108mm，速度 739 m/s，下坠高度 10.0m
2000m时：装甲穿深 75mm，速度 573 m/s，下坠高度 44.8m

额外装甲

附加防护：车身和炮塔附上5mm装甲板。
添加它们主要是为了保护坦克免受大规模反坦克步枪火力的伤害，这对装甲较薄的一侧来说是危险的。
虽然无法阻停穿甲子弹，这种附加装甲可以使其失稳或导致其碎裂，然后才击中主装甲保护车体。

Smoke Mortars
