The Type 210 automatic single 100 mm naval gun is the Chinese modification of the Compact model of the French 100 mm naval gun. There are at least two variants, with both sharing similar characteristics with the French weapon.^[1]

The Type 210 was developed to make the French gun suitable for Chinese deployment. The French gun was incompatible with Soviet and Chinese electronics; it was easier to make the gun compatible with these electronics, and Western electronics, than to alter the electronic suites already aboard warships. Furthermore, the Chinese added the capability to fire laser- and infrared-guided shells; this required significant changes to the magazine.^{[citation needed]}

The weapon's maximum rate of fire for a single type of unguided round was 90 rounds per minute. The rate of fire was reduced when switching between different types of ammunition.^[1]

The Type H/PJ87 100 mm naval gun is a further development of the Type 210,^[1] mounted on a stealth modified turret to reduce radar cross-section. It armed the early Type 052-series destroyers^[2] and will arm the Type 054B frigate.
