The H/PJ-17 or PJ17 is a single-barreled 30 mm (1.2 in) naval gun employed by the People's Liberation Army Navy. The H/PJ-17 is designed as a close-in defensive weapon for amphibious landing ships, corvettes, and patrol boats.

History
editOlder ships of the People's Liberation Army Navy commonly use the AK-630 close-in weapon system, which has an automatic engagement mode using MR-123 radar and a manual control mode where an operator can aim the gun using an instrument post on the deck, exposed to the elements. The AK-630 system has a bulky autoloader that protrudes through the deck, making it unsuitable for ships with smaller tonnage. China sought to develop a lightweight naval gun that could be mounted on small ships. The H/PJ-17 design began development in 2007, with the weapon certified in 2010.[1]
Design
editThe H/PJ-17 is a low-cost, lightweight, non-deck penetrating, remotely controlled weapon station with daylight optics and an LLP12A fire-control system, combining an electro-optical (EO) sight and a radar.[1] The H/PJ-17 turret has a weight of 1,500 kg (1.5 t), a single barrel of 30 × 165mm autocannon, a firing rate of 300 rounds per minute, a ready ammunition box of 100 rounds, an effective range of 3,000 m (1.6 nmi) against anti-ship missiles, and a maximum range of 8,000 m (4.3 nmi).[2]
The H/PJ-17 has multiple ways to engage the target. The gun can receive target information from the ship's radar and automatically engage the target; it can also rely on its own tracking system without any connection to the ship.[1] It also has multiple manual engagement modes. It can be controlled by the weapon station inside the ship or a manual seat on the gun turret itself. The seat is located on the right side of the barrel, where the operator can access the control console with a joystick, EO sight, the backup optical sight, or an iron sight to aim and fire the gun.[1][2]
Operational history
editThe H/PJ-17 is mounted on the Type 056 corvette[3][4] and Type 072A landing ship.[5]
