Tactical-technical requirements for a self propelled 152 mm howitzer on the KV-7 chassis
The 152 mm self propelled howitzer is similar in design to the KV-7 tank and is designed to be used for destruction of fortifications at close range
- Mass: 50-55 tons
- Armour: analogous to the armour of the KV-7 tank
- Armament:
- 1 152 mm howitzer
Horizontal traverse: +/- 7.5 degrees
Vertical traverse: +12 degrees, -5 degrees - DT machine guns:
- Front: 1
- Rear: 2
Horizontal traverse: 30 degrees
Vertical traverse: +15 degrees, -5 degrees - Ammunition capacity:
- At least 30 rounds for the 152 mm howitzer
- 40 machine gun disk magazines
- Crew: 6
- Hull: the same as the KV-7 tank, with the exception of howitzer mountings.
- Fighting compartment and armament:
- The fighting compartment must allow for comfortable placement of the crew and have 360 degree observation devices.
- To increase the amount of ammunition carried onboard and ensure convenient placement, it is acceptable to put the fuel tanks on the floor of the fighting compartment.
- To increase the rate of fire and make loading the howitzer easier, it is desirable to at least partially mechanize the loading process (supplying the shell and propellant).
- The mobility characteristics, engine, running gear, transmission, and communications equipment is analogous to that of the KV-7.
Notes: the factory is permitted to make changes and additions to these tactical-technical requirements to improve the design with the approval of the NKO (BTU) and NKTP.
