The Y-8 maritime patrol aircraft (MPA) is the land-based, long-range turboprop patrol aircraft developed by Shaanxi Aircraft Industry Co. for the PLA Navy.
The Y-8 maritime patrol aircraft (MPA) is the land-based maritime patrol and anti-submarine warfare aircraft based on the Shaanxi Aircraft Industry Corporation Y-8 turboprop transport. A small number of the aircraft has been operational in the PLA Naval Air Force (PLANAF) since the mid-1980s. This was the first special purpose variant of the Y-8 military transport aircraft being developed.
In 1983, Shaanxi Aircraft Company (now Shaanxi Aircraft Industry Corporation) was requested to develop a special purpose aircraft on the basis of its Y-8 turboprop transport aircraft (Chinese licensed copy of the Soviet/Russian An-12 Cub) that can perform long-range maritime patrol, reconnaissance, and search and rescue (SAR) missions. The development task was officially assigned to Shaanxi in October 1983, with the target set to deliver the first plane to the PLANAF in 1984. The design proposal by Shaanxi was approved in November 1983.

The Y-8MPA is based on the airframe of the basic variant Y-8 transport aircraft, but fitted with upgraded avionics and various mission equipment for long-range maritime flight. The aircraft is equipped with search radar, omega navigation system, self-defence electronic countermeasures (ECM) suite, optical/infrared cameras, sonobuoys, and sonar receiver. The rear cargo door was removed and replaced by a large mission equipment window for sonobuoys racks and cameras. The rear turret was also removed and replaced by the sonar operator seat.
Shaanxi achieved to finish the development in less than a year, issuing 11,000 pages of blue prints and conducting over 20 tests. The first Y-8MPA was delivered to the PLANAF in late 1984, and the aircraft received national design certificate in 1985. A Y-8MPA plane conducted five reconnaissance missions to the Xisha (Paracel), Zhongsha, and Nansha (Spratly) Islands in the South China Sea between March and June 1986, covering a total journey of 17,000km. The aircraft obtained a large amount of aerial photos of these islands, which were regarded as highly valuable to support the PLA’s operation in the region later.
陕西飞机公司在不到一年中完成发展，发出11,000页蓝图和进行超过20项测试。第一架Y-8 MPA在1984年后期被交付到PLANAF，而且飞机在1985年接受了国家设计证明书。一架Y-8 MPA飞机在1986年3月和6月之间的南海西沙（Xisha，Paracel)，中沙（Zhongsha）和南沙（Nansha)岛执行五个侦察任务，覆盖总行程17,000公里。飞机获得了这些岛的很多空中照片，被认为是高度有价值在之后去支援PLA的操作。
The PLA Navy Y-8 MPA are frequently seen flying over foreign warships in the Yellow Sea and East China Sea regions, or loitering close to the coast of neighbouring countries including Japan, South Korea and Taiwan.
Since the late 1990s, the PLANAF Y-8MPA aircraft has been frequently spotted operating in the East China Sea region, chasing foreign warships and flying near foreign airspace. Some of these planes are believed to be fitted with special mission equipment for electronic and signal intelligence (ELINT/SIGINT) missions. Both South Korea Air Force and Japan Air Self-Defence Force have sent fighter jets to intercept these Y-8MPA planes in the past to stop them flying too close to their airspace.
自从1990年后期以后，PLANAF Y-8 MPA飞机已经被时常看见在中国海洋区域东部中操作，追赶外国军舰和在接近国外空域附近飞行。一些飞机被相信为装备专用任务装备用于电子和通信情报（ELINT/SIGINT）任务配备。在过去韩国空军和日本空中自卫队两者已经派喷气战斗机去拦截这些Y-8 MPA飞机阻止它们太接近他们的空域附近飞行。
The Y-8MPA has been extensively upgraded with improved avionics and mission equipment. The aircraft is equipped with Litton (now part of Northrop Grumman) APSO-504(V)3 surface search radar accommodated in the under-chin radome. The aircraft is also upgraded with improved radio, inertial navigation system (INS), Omega global navigation system.
Y-8 MPA已经广泛地升级使用改进的航空电子和任务设备。飞机装备Litton（现在诺斯罗普·格鲁门（Northrop Grumman）的部分）APSO-504（V）3水面搜索雷达安装机身下前下方雷达天线罩中。飞机也升级使用改进的无线电、惯性导航系统（INX）、欧米加（Omega）全球导航系统。
Mission equipments include: infrared submarine detecting set, medium-/high-altitude optical camera, low-altitude optical camera, infrared camera, sonobuoys, sonar receiver, UHF radio marker beacon receiver, and five-man/single-man life boats. The aircraft has been added with an additional seat for the radar operator, and the original tail cannon turret on the Y-8 was removed and replaced by the sonar operator cabin.
The Y-8 MPA has a large rectangle camera window at its tail. The aircraft may also be fitted with electronic intelligence equipment.
Additionally the aircraft is also fitted with self-defence electronic countermeasures (ECM) suite consisting of all-aspect radar warning receiver (RWR) and chaff/flare dispenser.
