The 152 mm FRAG-HE 3OF61 projectile is a separate loading item of ammunition consisting of the projectile and a charge system contained in a lacquered steel cartridge case. The relatively thin-walled projectile is of high-fragmentation steel with a long streamlined ogive and a shallow bourrelet. The main projectile body is basically the same as that for the FRAG-HE OF-43 and is 1.5 to 2 times more effective on target than the 152 mm FRAG-HE OF-540. A single copper drive band encircles the projectile just forward
of the screw-on Base Bleed (BB) tail unit. The contents are nominally 7.8 kg of A-IX-2 (RDX 72 per cent, Aluminium 23 per cent, Wax 4 per cent). This payload, combined with the high-fragmentation steel body, is claimed to provide the 152 mm FRAG-HE 3OF61 with an on-target effect 1.5 to 2 times that of the 152 mm FRAG-HE OF-540 (see separate entry). The nose of the projectile is threaded to accept a variety of fuzes but no firm information is yet forthcoming regarding the models or types involved; mention has been made of KZ-88 point impact and RGM-2 delay (0.027 to 0.055 second) fuzes. The cartridge case involved is lacquered steel with a KV-4 percussion primer in the base. No information is available regarding the weight and type of propellant involved. Maximum muzzle velocity is 828 m/s and maximum range 29,000 m. The 152 mm FRAG-HE-BB 3OF61 projectile may be regarded as the long-range counterpart of the 152 mm 3OF45 and is a close design relation to the other 152 mm ammunition developments. It is intended for general operational use with the latest generation of Russian Federation and Associated States (CIS) long-barrelled 152 mm gun-howitzers. The 152 mm FRAG-HE 3OF61 is issued with a single cartridge case to form the 3VOF91 round. The 152 mm FRAG-HE-BB 3OF61 is marketed by VO GED, Moscow. Applications include 152 mm Gun-Howitzer 2A65 ( M1987 or MSTA-B). Self-propelled equipments include: 152 mm 2S19 Self-propelled Gun-Howitzer; 152 mm Self-propelled Howitzer ONDAVA.
