45mm Complete Round, Fixed, Frag, UO-243
This round is fired from the now obsolete 45mm anti-tank guns M1932, M1937, and M1942; and from the 45mm tank guns M1932 and M1934, which were mounted in the obsolete Soviet T-70 light tank. (The T-70 tank is obsolete, but its reappearance is still possible.)
Fragmentation rounds are used to destroy personnel and equipment. They are designed to produce the maximum number of lethal fragments. Either the KT-1 or KTM-1 fuze is used in this round.
The following complete rounds are variants of the illustrated round:
UO-243A, with O-240A projectile using the KTM-1 fuze; and
UO-243M with O-240 or O-240M projectile using the KTM-1 fuze.
These variants are fired from the same weapons and, except for differences in markings, are similar to the UO-243 in external appearance.

Caliber: 45mm (1.77 in)
Weight of complete round: 2.8kg (6.31 lbs)
Weight of projectile, as fired: 2.1kg (4.64 lbs)

45mm Complete Round, Fixed, AP-T, UBR-243
This round is fired from the now obsolete 45mm anti-tank guns M1932, M1937, and M1942; and from the 45mm tank guns M1932 and M1934, which were mounted in the obsolete Soviet T-70 light tank. The round is used against tanks, various other types of armored vehicles, and field fortifications. Its projectile contains a small base cavity filled with high explosive.
The BR-240 armor-piercing tracer projectile in this round uses the MD-2 or the MD-5 fuze. The same complete round (with projectile BR-240 and fuze MD-2 or MD-5, as shown in the above drawing) has been found with the identification code UBZR-243 stenciled on the cartridge case. Although this code signifies an API-T complete round, analysis discloses that the projectile has no incendiary element.
The complete round UB-243, with armor-piercing projectile B-240 and fuze MD-2 or MD-5, is a variant of the illustrated round. It is basically the same as the UBR-243, but its projectile has no tracer element. It is fired from the same weapons and, except for differences in markings, it is almost identical to the UBR-243 in external appearance.

45mm Complete Round, Fixed, HVAP-T, UBR-243P
This round is fired from the now obsolete 45mm anti-tank guns M1932, M1937, and M1942; and from the 45mm tank guns M1932 and M1934, which were mounted in the obsolete Soviet T-70 light tank. The round is used against tanks, various other types of armored vehicles, and armored fortifications. Its projectile is a solid shot with a tungsten carbide core.
The BR-240P high-velocity, armor-piercing tracer projectile in this round has no fuze.
Note: Stamped numbers shown on the body of the projectile in the above illustration were taken from an actual projectile. They are believed to identify the projectile by manufacturing plant, lot number, and year of manufacture. A fourth number (possibly the smelt number) sometimes appears in the same line, or on the opposite side of the projectile. The identification code number which is stenciled on all other types of projectiles apparently does not appear on HVAP projectiles.

Caliber: 45mm (1.77 in)
Weight of complete round: 1.86kg (4.1 lbs)
Weight of projectile, as fired: 0.87kg (1.91 lbs)

Packaging
The illustrated wooden container has a capacity of 10 rounds, with a gross weight of about 27kg (59 lbs). The gross weight may be stenciled on the box, in the form БРУТТО 27 КГ. The abbreviation ПОДКАЛ, as shown in the above drawing, means that the packing box contains "subcaliber" (HVAP) ammunition.
Two types of metal carrying cases, each with a capacity of five rounds, may also be found. One type is provided with wooden cradles; the other has built-in pressed-metal contour blocking. Both types have a hinged lid, finger-tip pressure latches, and a carrying handle.
