Soviet anti-tank rocket launcher РПР-82

Post by YC Chen » 29 Jul 2017 17:21

Hello,

In a local artillery collection in my city there is a Soviet anti-tank rocket launcher(see attachment) that was labelled as СПГ-82. However there are many differences in detail between this weapon and the СПГ-82.

A few days ago when going through an old Russian book on rocket weapons I came across a photo showing a rocket launcher which is identical to the one in the local collection. It is named РПР-82 and there is some description. I cannot read Russian so I'm not sure about what it says - does it mean that РПР-82 was a prototype of СПГ-82, and after its adoption by the army the name changed to СПГ-82?

Any further information on the rocket launcher РПР-82 and its relationship with СПГ-82 would be appreciated. Thanks in advance!

Hi!
In the Soviet book it is written:
"In June 1945, RBG and RPR-82 were introduced into the states of the armament of the troops, having received the SPG-82 index (heavy antitank grenade launcher)"
This strange information, because the SPG-82 was adopted in the 1950s.

Many thanks, karlik! It confirms my machine-translation result.

I have attached the cover of this book. What is even more strange is that the book seems to be published in 1949. So if SPG-82 was introduced in 1950s, how could a 1949 book predict its existence...

Still waiting for more information on this "RPR-82" rocket launcher...

SPG-82 it was developed since 1942, but was adopted in 1950. So it's strange that in a book with the stamp "Secret" it is written that the grenade launcher was adopted in 1945 ???????

See here for information http://shooting-iron.ru/load/220-1-0-847

The reason that why it was not adopted is given here:
К вопросу о ранних советских РПГ.
Точнее, почему глупые люди не сделали РПГ-7 прямо в 1941-ом. Из отчета об испытаниях ПТР РПР-82. Имеем окоп 3-1-1,5 м, в нем ПТР (аналог Офенрора) и чучела. После выстрела позади казенного среза ружья обвалило стенку окопа с воронкой 1 на 0,8 м, глубиной 0,3 м, чучела сильно обсыпало грунтом. Опалений чучел не было обнаружено. Затем к задней стенке окопа в створе с казенным срезом ПТР прикрепили фанерный лист и снова выстрелили. Лист пробило и опалило. При последующих выстрелах явления повторялись.

Блиндаж 3-2,5-2,25 м. Дульная часть ствола вставлена в щель для наблюдений. Собака последовательно привязывалась сбоку ружья на 2 м, 1 м и к самому щиту на место заряжающего. После каждого выстрела образовывалось столько газов, что "войти в блиндаж без противогаза невозможно было, но на собаке признаков удушения установлено не было. В последнем случае, когда собака была привязана к щиту, газами немного опалило ей шерсть". Поскольку у солдат шерсти нет, им не страшно :).
Один выстрел из окна деревянного помещения, 4,5-5-3,15 м. Газами из сопла гранаты впереди ружья была вышиблена рама окна, были оторваны доски стенки, а газами из казенного среза была разрушена задняя стенка помещения. Хотя скопление газов было меньше, опять-таки упомянули противогаз.
Тема загрязнения стекол щита несгоревшими частицами, (не)удобств перемещения и поведения порохов при низкой температуре раскрыта отдельно :).

The back bast from the rocket was so fierce that it could not be used from trenches or dug outs so it was not considered a good defensible weapon.

To the question of the early Soviet RPGs.
More precisely, why stupid people did not make the RPG-7 right in 1941. From the report on the PTR RPR-82 tests. We have a trench of 3-1-1.5 m, it's PTR (analogous to Ofenror) and stuffed. After the shot behind the state cut, the gun fell off the wall of the trench with a funnel 1 at 0.8 m, a depth of 0.3 m, the stuffed heavily sprinkled with soil. No scarecrow was found. Then a plywood sheet was attached to the back wall of the trench in the alignment with the official section of the PTR, and fired again. The sheet broke through and scorched. During subsequent shots, the phenomena were repeated.

The dug-out is 3-2,5-2,25 m. The muzzle of the trunk is inserted into the observation slot. The dog was sequentially tied to the side of the gun at 2 m, 1 m and to the shield itself in the place of the loader. After each shot, there were so many gases that "it was impossible to enter the dugout without a gas mask, but there were no signs of strangulation on the dog." In the latter case, when the dog was tied to a shield, the wool burned a little. " Since soldiers do not have wool, they are not afraid :).
One shot from the window of the wooden room, 4,5-5-3,15 m. Gas from the grenade nozzle in front of the gun was knocked out the frame of the window, the boards of the wall were torn off, and the back wall of the room was destroyed by gasses from the state cut. Although the accumulation of gases was less, the gas mask was again mentioned.
The topic of contamination of the shield glass with unburned particles, (not) the convenience of moving and the behavior of gunpowder at a low temperature is disclosed separately :).

Wow, really interesting! Thank you for sharing this. At least this must be the reason for the oversized shield (and the adjacent wheels) which made RPR-82 and SPG-82 very bulky weapons.

"contamination of the shield glass with unburned particles" may suggest that at that time the quality of rocket propellant made by Soviet engineers was not good enough. It is said that similar problems were also encountered by Chinese arsenals when they attempted to copy the 2.36in Bazooka rocket in 1947.
