Description
The Type 65 is the twin-37mm towed anti-aircraft artillery (AAA) developed in the 1960s as a successor to the Soviet M1939 single-barrel 37mm AAA (produced in China as Type 55). The weapon was designed primarily to engage airborne targets within a distance of 8,500m (or slant range of 3,500m), but it can also be used against land or water surface targets. Based on the Type 65 design, the PLA developed a number of derivations including the Type 74/74SD towed AAA, Type 79-III towed AAA, Type 76 shipboard AAA, and Type 88 self-propelled AAA.

The Type 74 is an improved variant of the Type 65 introduced in 1974. The weapon share the same 37mm cannon and ammunitions as the Type 65, but can be operated either manually or remotely by the fire-control unit consisting of an electro-optical director and a target searching radar. This enables the weapon to operate under day/night, all-weather conditions.

Description
Sights w/magnification: optical mechanical computing sight
Azimuth warning receiver: 1l15-1
Off-carriage radar: Optional. The Chinese Type 311 continuous wave I/J-band fire control radar was designed and produced to support 37mm and 57mm guns. The trailer-mount radar with computer automation can conduct surveillance and target acquisition. It has at least three variants, with ranges of 30km (311-A), 35km (311-B), and 40km (311-C). Target tracking range is 25km for the -A variant. Emplacement time is 15 minutes. Radar gives user weapons night-time and adverse weather capability. This radar has been exported.
