Қытайдың жақын қашықтықтағы қорғаныс қару жүйесі Type 730

Chinese automated close in weapons system

The system's primary purpose is defense against anti ship missiles, and other precision guided weapons. However, it can also be employed against fixed/rotary wing aircraft, ships and other small craft, coastal targets, and floating mines. Though externally similar to the Dutch Goalkeeper in appearance, it is thought to operate indigenous radar and optical systems. Another reported source of technology was reported to be in France, which had experimented with the same General Electric EX 83 mount for their CIWS requirements. Two systems, SAGEM's SAMOS and the Thomson CSF's SATAN were under evaluation in October 1987. The SAGEM SAMOS system featured the EX 83 mount with a SAGEM VOLCAN optical director, while the Thomson CSF variant was controlled with an off board Castor IIJ fire control radar. Photos of the prototype Type 730 unit under trial apparently shows a SAGEM VOLCAN EO director in place of the domestic OFC 3/H/ZGJ 4 EO director.

The TR47C radar operates in the same way of AN/APY 1/2 radar on board E 3 Sentry in that the azimuth is scanned mechanically, while the elevation is scanned electronically, incorporating a total of 169 transceivers of phased array technology that enables the radar to pick up the splashes of 30 mm rounds. Like the western CIWS, the information is processed on site, via local computers of the radar and the gun mount, thus providing faster reaction time than the Russian design in which the radar and fire control system are separately located. The system can track a sea skimming target with 0.1 square metre radar cross section at 8 km, extended to 15 km if the radar cross section is increased to 2 square metres, and further extended to 20 km if the radar cross section is increased to 10 square metres, though the targets could not be engaged until much closer (3 km) due to the limited range of the gun.

The OFC 3 system is modular design that comprises a laser range finder, a color TV camera, and an IR camera, and the laser range finder can be replaced by a laser designator (for a laser beam riding SAM), the TV camera can be replaced by a night vision camera, and the IR camera can be replaced by an ImIR, at higher cost. Development to incorporate the dual band IR, night vision camera, and the color TV camera is reportedly in progress. Type 730 CIWS is an autonomous closed loop system and thus offers faster reaction time than the Russian AK 630. Type 730 CIWS is fully compatible with Chinese and European combat data systems such as ZKJ 1, ZKJ 4, ZKJ 4A 3, ZKJ 5, ZKJ 6, ZKJ 7, H/ZBJ 1, and Thomson CSF TAVITAC, and can be directly integrated with these combat data systems without any modification.

The 30 mm Gatling gun mount designated as H/PJ 12 is extremely similar to the General Electric GAU 8/A Avenger. Although there are sources claiming that it is the Chinese version of the Russian Gryazev Shipunov GSh 6 30 Gatling gun, this appears to be unlikely, since the Russian Gatling gun uses bleed gas actuation. H/PJ 12 is versatile in that its FCS can be either separately installed at different locations like the Soviet AK 630, or directly integrated on the gun mount. Like the American GAU 8/A Avenger, it is recommended not to fire longer than a single minute at a rate of 4,200 rounds per minute, after which the generated heat would begin melting the rifling of the barrels, shortening its useful life. Rates of fire beyond 4,200 rounds per minute increase wear. There are one (Type 730) or two (Type 730B/C, LD 2000) ammunition drums each contains 640 (Type 730) or 500 (Type 730B/C, LD 2000) rounds, and other versions of the ammunition drums have been reportedly developed.

The system has been fitted on board the Type 052 (after 2011 refit), Type 052B, Type 052C, Type 052D, Type 051C destroyers, F 22P, Type 054A frigates, Parchim I, C28A corvettes so far, and may replace some Type 76 mounts on older combatants. The Type 1130 has been deployed on aircraft carriers Liaoning and Shandong, Type 055 destroyers, Type 075 landing helicopter docks, later variants of Type 052D destroyers and Type 054A frigates, and Type 051B destroyers (after 2011 refit). LD 2000 has been deployed by People's Liberation Army Ground Force and Marines for local air defense mission.

Original variant.

Re engineered Type 730 system to utilize off mount target tracking sensor. The system integrates the 30 mm mounting with a network of off mount tracking and surveillance sensors consisting of surveillance radar, fire control radar and electro optical sensor system.

The LD 2000 (LD: Lu Dun, 陆盾, meaning Land Shield) SPAAGM is a Chinese developed land based close in weapon system with counter rocket, artillery, and mortar (C RAM) capability. LD 2000 is based on the Chinese Navy's Type 730. Part of the HQ 6A system, it pairs with HQ 64 missiles and a Counter Battery Radar. The radar is supplemented by a thermal imaging sight. The weapon is loaded with 1,000 rounds, enough, apparently, for about 48 potential target engagements, same as its naval counterpart, with effective range of 2.5 to 3.5 km. LD 2000 and HQ 6A system is deployed by People's Liberation Army since 2011.

Further development of Type 730 resulted in the Type 1130, which first appeared on Chinese aircraft carrier Liaoning. This successor of Type 730 is also 30 mm caliber and has a total 11 barrels, with reported rate of fire of 11,000 rounds per minute. The Type 003 Chinese aircraft carrier Fujian launched on 17 June 2022 revealed a Type 1130 CIWS with a modified radar which some have speculated to be a new AESA radar.
