That looks like the new batch ships.

Type 56 need to incorporate the new AR500B maritime surveillance UAH as organic sensor via JSCh
But sofar it is limited by scant mission performance of
a mission load of 70kg, and a maximum endurance of 4h; a control radius of 100km, a maximum level flight speed of 140km/h, a cruising speed of 120km/h, and a service ceiling of 4000m. It can be widely used to perform wide-area surveillance and identification tasks at sea.

I hope they can improve on the load so that it can carry dipping sonar and onboard data link to the ship

【AR-500B舰载型无人直升机成功首飞】11月27日,航空工业研制的AR-500B舰载型无人直升机在鄱阳试飞基地首飞成功,该型号的成功研制填补了我国轻小型舰载无人直升机领域的空白。AR-500B舰载型无人直升机最大起飞重量500kg,任务载荷 70kg,最大续航时间4h;控制半径100km,最大平飞速度140km/h,巡航速度120km/h,使用升限4000m,可以广泛用于执行海面广域监视与识别任务。

为适应舰载无人直升机停放空间小、工作环境恶劣、起降过程风险大、电磁环境复杂等不利因素,直升机所设计团队在原型机的基础上换装重油发动机,对燃油、结构、电气、飞控系统进行适应性改装设计。

针对无人直升机的海上使用需求,直升机所设计团队开展了小型电动助降装置、着舰引导系统和自动着舰控制律等设计研制;针对海上使用环境,开展了“三防”(防湿热、防霉菌、防盐雾)环境试验,使AR-500B舰载型无人直升机能够基本适应海上及船上环境。

AR-500B ship-based unmanned helicopter successfully made its first flight

On November 27, the AR-500B carrier-based unmanned helicopter developed by the AVIC successfully flew for the first time at the Poyang test flight base. The successful development of this model has filled the gap in the field of light and small ship-borne unmanned helicopters in China. AR-500B ship-based unmanned helicopter has a maximum take-off weight of 500kg, a mission load of 70kg, and a maximum endurance of 4h; a control radius of 100km, a maximum level flight speed of 140km/h, a cruising speed of 120km/h, and a service ceiling of 4000m. It can be widely used to perform wide-area surveillance and identification tasks at sea.

In order to adapt to difficult factors such as small parking space of the shipborne and harsh working environment, the high risk of take-off and landing, and the complicated electromagnetic environment, the helicopter design team replaced the original prototype with heavy oil engine and design adaptive modification on the fuel, structure, electrical and flight control system.

In response to the needs of unmanned helicopters at sea, the design team of the Helicopter Institute has carried out the design and development of small electrical landing assistance devices, landing guidance systems and control rules for automatic landing. Specifically against the maritime environment, the "Three Preventions" (anti-humidity, anti-mold, anti-salt spray) environmental test has been carried out, such that the AR-500B ship-based unmanned helicopter could basically adapt to the marine and shipborne environment.

I am excited about this AR-500B It will give type 56 extra pair of eye and ear if they can built small enough radar of dipping sonar Here it is from GT

China's first vessel-borne lightweight helicopter drone makes maiden flight

China's first domestically developed vessel-borne lightweight helicopter drone has recently made its maiden flight, its maker announced. It is designed to conduct maritime monitoring and identification tasks, and is expected to be used on board smaller vessels including corvettes and coast guard ships for missions like patrol and search and rescue, analysts predicted.

Developed by state-owned Aviation Industry Corporation of China (AVIC), the AR-500B vessel-borne unmanned helicopter successfully made its maiden flight at a test facility in Poyang county, East China's Jiangxi Province on November 27, according to a statement released by AVIC China Helicopter Research and Development Institute on Wednesday.

During the test flight, which lasted for about half an hour, an AR-500B ran subjects including takeoff, hovering, maneuvering and landing.

The successful development of the AR-500B made up for China's lack of a type of ship-based lightweight helicopter drone, the statement said.

Compared with larger, heavier vessel-borne helicopter drones, a lightweight one can be flexibly deployed on all kinds of maritime platforms including smaller ones like corvettes or even civilian ships, Wei Dongxu, a Beijing-based military expert, told the Global Times on Thursday.


The AR-500B has a maximum takeoff weight of 500 kilograms, a mission payload of 70 kilograms, a maximum endurance of four hours, an operational radius of 100 kilometers and a ceiling of 4,000 meters. It can fly at 140 kilometers an hour and conduct missions like monitoring a vast maritime surface area and identifying targets, according to its developer.

The helicopter drone will serve as far-reaching eyes for warships, and it can possibly also provide communication relay and guidance functions, Wei said, noting that it can also be deployed to guard the coastline.

The drone not only has military applications, but also can be used for civilian purposes, Wei said, noting that it can also be used in maritime search and rescue operations.

In order to make the helicopter drone capable of operating on a ship, the development team designed a landing assistance device, a landing guidance system and an automatic landing control system. The craft has also been tested in environments with high humidity, high temperature, mould, and salt spray.


The AR-500B opted to use a heavy oil engine and adopted special designs in fuel, structure, electronics and avionics systems to deal with challenges including limited hangar space on ships, extreme working conditions, high risks in takeoff and landing and complicated electromagnetic environments, AVIC said.

, which looks much bigger than the AR-500B, was reportedly spotted on the flight deck of China's Type 075 amphibious assault ship in July. Media speculated that the Type 075 could host this type of helicopter drone.

this little unmanned helicopter has many uses and could in theory be deployed on the Type 054A too

when the threat of enemy submarine is high always warships deploy 24/7 ASW helicopters

when the Z9C lands for refuelling the AR-500B can take off until the Z9C is ready again

I believe there is a side compartment on the Type 054A for exactly this purpose

this helicopter can also be scaled to LHD/LHA use but maybe not full carriers

PLAN's own Firescout?

From near to far: 625 "Bazhong", another 056 shadowed by her, 552 "Guangyuan" and 520 "Hanzhong", probably in an ASW exercise (note the sonar cable towed by 625).

552 is an older batch from 625, but it has been refitted with the flat panel SATCOM (could also be for UAV and aircraft communications), with the location offset to the starboard instead of the center on top of the bridge. Other 056/56A has this refitted on the aft of the ship. The fleet wide refits of this device points to its importance with the PLAN.
