The Soviets made an 8" howitzer too. It was introduced in 1975 and it's still in service.
The 2A44 gun is mounted on the 2S7 Pion self propelled gun.
The rounds weigh 227 lb. or 240 lb.
A nuke round was developed.
I have ranges from wikipedia.
Ukraine managed us US 8" projectiles.
This is just about all I know about this gun.
I assume there's an HE round, because every howitzer has one.
FASCAM? DPICM? Chem? Smoke?
Base bleed? Rocket Assist?
Who knows!
A copy of Jane's Artillery '95-96 is en route. Maybe it will have some answers.
Sort of related: There's scanty information online about the gun on the M110 and M110A2 SPG's too. Still digging there too.
For what it worth - The primary projectiles are the OF43 high-explosive fragmentation (HE-FRAG) round and the 3OF44 rocket-assisted projectile. The HE-FRAG round weighs 110 kg, contains 17.8 kg of explosive, has a maximum firing range of 37.5 km with a full charge, and an initial velocity of 960 m/s. The rocket-assisted projectile weighs 103 kg, contains 13.8 kg of explosive, and has a maximum firing range of 47.5 km. Additionally, a concrete-piercing round, a special munition with a nuclear warhead, and a chemical round have been developed for the gun.
ReplyDeleteI got my copy of Janes Armour and Artillery 1995-96 today and it matches your numbers! Thanks!
DeleteThe chem round doesn't need much real world information to make it with GURPS. The nuke round I mostly need the yield.
Some kind of APEX round for the concrete piercing... The APHEX stats appear to do what I think that should do, but it'd be nice to have real world info on the filler and such.

DeleteModel of Soviet nuclear projectile. The projectile is not valid. The radiation level is zero. Models shells were displayed at the exhibition in Chelyabinsk. 203-mm projectile 3BV2. Power projectile – 0,9 kilotons. Firing range 18 000 – 30 000 meters. For firing the guns towed: B-4, as well as self-propelled guns: 2S7 and 2S7M. The last batch of nuclear 3BV2 projectile made in March 1990. Guaranteed projectile life – 10-years old. In March 2000, the shelf life of these projectile was extended for 5-years old.

This site helped a lot too. https://weaponsystems.net/system/145-203mm+shells+for+2A44+howitzer
DeleteOnce you have the names for the shells, it's easier to find the details on the others.
Still looking for the chem and smoke, if any.
