Description

For the 2S7 Pion self-propelled howitzer a special range of ammunition was developed. The 2S7 features the massive 2A44 howitzer with a length of 56 calibers.

The 2A44 howitzer has a similar 203mm bore diameter as the earlier B-4 towed howitzer, and during production of the ordnance the Barrikady plant even used some machinery that was once used to produce the B-4. Despite this the World War 2 era and modern range of 203mm ammunition is not interchangeable. The new shells are larger and able to withstand far higher pressures.

Both conventional and nuclear shells were developed for the 2S7. The charges are of the separate kind and are bagged. For transporting ammunition a handcart is used. The 2S7 features a mechanized loading tray for assisted loading of shells and charges.

List of projectile types

3OF43
HE-Frag projectile used in 3VOF34 long range and 3VOF42 short range round. Nicknamed "Albatross".
3OF44
HE-Frag projectile used in 3VOF35 rocket assisted round. Nicknamed "Burevestnik-2", which translates to "petrel".
3O14
Cluster munition shell used in 3VO15 long range and 3VO16 short range round.
3G3 Galyan
Concrete piercing shell used in 2VG11 round. Designed to strike hardened targets, such as command bunkers, runways and hardened aircraft shelters for frontline aviation.
3BV2 Kleshchevina
Nuclear shell, introduced in 1977. Derived from 3BV3 designed for 152mm guns. Plutonium based weapon with yield of about 0.5 to 1 Kt. Could be fired from the towed B-4M and 2S7 Pion.
Sazhenets
Nuclear shell. Improved design over Kleshchevina, with similar yield. Actual improvement unknown, but guessed to be shaped more like 3OF43 for improved accuracy and range, but loosing compatibility with B-4M.
Perforator
Nuclear shell, developed but reportedly never adopted. Unknown whether development was ever concluded. The name suggests that this nuclear shell was designed to strike hardened targets instead of troops in the open.
