The OF-45 is a Soviet/Russian 152 mm high-explosive fragmentation projectile for separate-loading artillery. GICHD describes it as a 1980s steel-bodied HE/FRAG round used with D-20 howitzers and expected around 2S3 Akatsiya positions in Ukraine, while Forecast International identifies OF-45 as part of the newer 152 mm ammunition family fired by the 2S19 Msta-S 2A64 cannon.
GICHD's explosive-ordnance guide for Ukraine identifies the OF-45 as a common 152 mm HE-fragmentation projectile in the theater, with fired rounds showing driving-band scoring and unexploded examples expected around abandoned or destroyed D-20 and 2S3 artillery positions.
The OF-45 is documented with Soviet/Russian 152 mm gun-howitzers and self-propelled howitzers rather than as a standalone weapon system.
| Firing weapon | Weapon type | Firing evidence |
|---|---|---|
 | 152 mm towed gun-howitzer | GICHD states that OF-45 rounds are used with D-20 howitzers and may be found as abandoned explosive ordnance around abandoned or destroyed D-20 positions in Ukraine. |
 | 152 mm tracked self-propelled howitzer | GICHD says OF-45 can also be expected in abandoned or destroyed 2S3 Akatsiya self-propelled 152 mm artillery. |
 | 152 mm towed howitzer | The 2A65 Msta-B reference identifies OF45 as the standard high-explosive projectile and lists the 43.56 kg mass, 823 m/s muzzle velocity, and 24.7 km maximum range figures used in this entry. Sources: 152 mm howitzer 2A65 Msta-B |
 | 152 mm self-propelled howitzer | Forecast International identifies OF-45 among the high-explosive-fragmentation ammunition types fired by the 2S19 Msta-S's 2A64 cannon. |
GICHD describes the OF-45 as a longer 152 mm HE/FRAG projectile with a steel body, hollow base, copper driving band, and RGM-2 impact fuze. Fired examples can show scoring on the driving band, while unfired or abandoned rounds are relevant to explosive-ordnance clearance around D-20 and 2S3 positions.
| Field cue | Sourced detail |
|---|---|
| Body and fill | Steel-bodied 152 x 864 mm projectile with 7.65 kg of A-IX-2 explosive fill. |
| Fuzing | Typically associated with an RGM-2 point-detonating impact fuze; GICHD notes that compatible 36 mm-thread proximity fuzes exist but simpler mechanical fuzing has been more commonly seen. |
| Use context | Used with D-20 howitzers and expected in 2S3 Akatsiya self-propelled artillery contexts; Forecast International also documents OF-45 in the 2S19 Msta-S 2A64 ammunition set. |
Forecast International says the former Soviet Union began developing the newer 152 mm ammunition family fired by the 2S19 Msta-S's 2A64 cannon in 1966.
GICHD describes the OF-45 as a common 152 mm HE/FRAG artillery projectile dating from the 1980s.
Forecast International reports that the 2S19 Msta-S was first fielded in 1989 and identifies OF-45 among the ammunition types fired by its 2A64 cannon.
GICHD's Ukraine guide lists the OF-45 among 152 mm projectiles encountered in the conflict environment and describes D-20 and 2S3 contexts where the round can be found as abandoned explosive ordnance.
