T-75 60mm mortar

The T-75 60mm mortar is a weapon developed based on the US-made M224 mortar. The research and development process of the T-75 began in 1984 , so it was originally named "XT-73" and was changed to "T-75" after it was finalized. The M224 60mm LWCMS is ideally suited to support airborne, air assault, mountain, ranger, Special Operations Forces and light infantry units. The M224 can be drop fired (conventional mode) or trigger fired (conventional or hand-held mode). A lightweight auxiliary baseplate is used when firing the mortar in the hand-held mode.

The M224 60mm Lightweight Mortar is a smooth bore, muzzle loading, high-angle-of-fire weapon. The cannon assembly is composed of the barrel, combination base cap, and firing mechanism. The mount consists of a bipod and a base plate which is provided with screw type elevating and traversing mechanisms to elevate/traverse the mortar. The M64 sight unit is attached to the bipod mount via a standard dovetail. An additional short range sight is attached to the base of the cannon tube for firing the mortar on the move and during assaults. It has a spring-type shock absorber to absorb the shock of recoil in firing. The M224 replaced the older (WWII era) M2 and M19, 60mm Mortars. These weapons only possessed 2,200 yards of effective range. The M224 was designed to fire all types of the older ammunition, but its primary rounds are of the newer, longer-range type.

The T-75 is smaller than the M-224. The M-224 has a total length of 1.016 meters, while the T-75 is only 0.748 meters; the M-224 weighs 21.11kg, while the T-75 only weighs 13.2kg. The round chassis of the M-224 is also significantly longer than the M-224. The T-75 is one size larger. Both have hand grips with heat dissipation rings, but the T-75's hand grip is located one-third of the gun body, while the M-224's is at the end, obviously to balance the center of gravity. The M-224 has a trigger on the hand grip , but the T-75 does not.

The T-75 is relatively light and easy to carry, but it comes at a price. The T-75's maximum range is only 2,117 meters. The normal rate of fire is 8 to 15 rounds per minute, and the maximum rate of fire is 30 rounds per minute. The maximum firing range of the M-224 is 3490 meters, the normal firing rate is 20 rounds per minute, the maximum firing rate is 30 rounds per minute, and the killing area is 15 x 15 square meters. After mass production, the T-75 quickly replaced the old Type 31 and Type 44 60 mm mortars.
