851 (originally known as DONGDIAO 232) is the electronic surveillance and missile tracking ship built by Shanghai-based Qiuxin Shipyard for the PLA Navy. The first and only hull was commissioned into the East Sea Fleet in 1999. The ship was observed collecting electronic intelligence (ELINT) off the coast of Japan during February 2000, shortly before several PLA Navy warships conducted an exercise in the East China Sea area.

中国851（最初即“东调”（Dongdiao） 232）是由上海建立的求新造船厂为PLA海军建造的电子监视和导弹跟踪船 。第一艘并也是仅有的一艘在1999年进入东海舰队服役。该船被观察到在2000年2月期间在日本沿海收集电子情报（ELINT），不久前几艘PLA海军军舰在中国东海区域实施一次演习。

The ship is armed with a manual dual-37mm AAA gun, two manual dual-25mm AAA guns, and a 3-cell 324mm torpedo launcher. A helicopter flight deck is located at the stern of the ship.

该舰装备有一门双管-37 mm AAA炮，二门手动双管-25 mm AAA炮和一座3-管324 mm鱼雷发射装置。一个直升飞机飞行甲板位于船的尾部。

Originally there were two large radar dishes located on the deck, possibly for missile tracking purpose. Following a recent refit, these dishes were replaced by three large radomes housing unknown equipment.

原来位于甲板上有二个大型雷达碟形天线，可能用于导弹跟踪用途。在最近一次改装后，这些碟形天线被三个大型天线罩代替遮蔽了未知设备。
