Jianyi / Antelope - Air Defense System

The Jianyi [Antelope] is self-propelled Air Defense System, consisted of four surface-to-air TC-1L missiles, mid-sized truck, target acquisition system, communication system, and fire control system. The TC-1L missile is a short range infrared guided missile with high kill probabilities against various air threats including helicopter, UAV, and low-altitude aircraft. The vehicle-mounted Jianyi air defense missile has a shooting height of 15~6000m and a range of 9~18km. The Antelope is a general-purposed air defense system which can be deployed in army, air force, and marine corps.

Air threats have posed a huge challenge to air defense forces with the evolution of technological weapons. The CCP has spared no effort in the development of new air attack weapons, such as the development of sophisticated aerial long-range attack weapons and cruise missiles, which have made significant achievements. The vehicle-mounted sword-air defense weapon system is solving the new air defense threats or the challenges of armed attack helicopters from the air. However, the performance of the weapon system must rely on skilled operators to integrate equipment and personnel, tactics and technology to achieve the task of defending Taiwan's airspace.

The Antelope Air Defense System (Antelope Air Defense System) is a land-launched air defense system developed by the Zhongshan Academy of Sciences of the Republic of China with the Tianjian I missile as the core. Research and development began in 1995 and the Hanguang 13 exercise in June 1997 It was made public for the first time. In 2005, it formally formed an army and joined the combat readiness.

The Tianjian-1 missile had completed the relevant tests before the F-CK-1 fighter decided to mass-produce in the early 1990s. However, after mass production, the senior management decided to reduce the request for the F-CK-1 fighter due to the purchase of fighters from the United States and France. The reduction in production of the Tianjian I, which was originally mass-produced with a quota of 250 aircraft, instantly exceeded the requirements of the Republic of China Air Force fighter jets. In addition, the Air Force inventory at that time still had a large number of AIM-9P4 air-to-air missiles, which put an extra pressure on the Air Force's logistics.

So the Chinese Academy of Sciences managed to change it to a vehicle-mounted land-launched missile. It was adopted by the Air Force, and its subordinates defended around the airport. The Chinese Academy of Sciences developed a radar, thermal imaging, and visual sighting control system based on the US-made land-launched missiles, which became a rare three-mode land-launched area air defense missile.

The launching station is operated by remote control, and on the left is a forward-looking infrared (FLIR) imitation of Texas Instruments for the shooter to remotely track and lock the target. In case of bad weather such as heavy rain and dense fog, the parameters measured by the radar can be converted into digital signals and input into the missile, and then launched, and the head-on mode can be set. The terminal adopts infrared guidance mode, which is an all-weather weapon.

The focus of the improvement is to change the TOYOTA civilian medium-duty truck with the 2008 model, the front bumper, the windows and the lights have been modified, the wiper is changed from three to two, and the wiper holder is added. The rear of the driverís seat is coated with refractory materials to prevent fires from burning down the carriage. The configuration of the launching station has not changed much, but the position and number of exhaust windows on its base have been changed, which provides a better exhaust emission effect of diesel generators. The IFF box on the front of the launching station is slightly different. This air defense system also includes a spare missile carrier developed with the same vehicle, but it is rarely seen.

In order to relieve the logistics load, the Chinese Academy of Sciences developed the Tianjian-1 land-launched version under the instructions of the General Staff Headquarters of the Ministry of National Defense. The missile body still maintains the Tianjian-1 architecture, but developed a land-use missile launch tower, so the effective range is the same as the one in service at the time. There is not much difference between the MIM-72/M48 Shushu missiles However, because of the use of a new type of infrared-guided marker, its anti-interference ability is better than that of American products.

The mass-produced vehicles are cheaper than the Hummer. TOYOTA DYNA trucks, the total scale of mass production is only 2 battalions mixed with T-82 anti-aircraft guns. There is no matching field reconnaissance radar and control center, all relying on radio voice instructions. The missile itself is better than the US-made weapons purchased in the past, but from the perspective of the integration of the air defense system, it is very rudimentary.

At the 2009 Taipei Aerospace Exhibition, the Air Force appeared an improved vehicle-mounted Jianyi air defense missile, which made the outside world know that the Hsinchu Air Force Base became the second unit equipped with this missile and received more system improvements to protect the area of the base from air defense.

At the Taipei International Aerospace and Defense Industry Exhibition in August 2015, Haijiís Haijian Ling missile system was officially exposed, and mass production is scheduled to start in 2020. At the Taipei International Aerospace and Defense Industry Exhibition in August 2017, in addition to the ship-borne sea antelope, the Chinese Academy of Sciences is also planning a land-launched version of the sea antelope. The missile launch system, radar, and fire control system are all mounted on heavy vehicles. It became a land-based short-range mobile air defense system.

The Jianyi anti-aircraft missile is mainly composed of a missile launching tower. The launching tower is equipped with a target reconnaissance system modified by the Tianjian-2 target finder. The shooting control system is written on the Windows 98 platform. Theoretically, the launching tower integrates target acquisition, With fire control capability and 4 Tianjian I missiles, enemy aircraft can be easily detected regardless of day or night. However, the Windows system has the inherent problem of poor stability, and the ROC Army lacks the concept of spiral upgrade, so the system is not stable enough. The later fire control software upgrades use the Windows XP platform to operate, but the limited hardware upgrades make the operation stable. The anti-aircraft missile can be operated by only two people. The shooter and the tracker work on the driver's seat of the truck, and they can also be manipulated outside the vehicle by cable connection.

Due to the lack of other integrated equipment, as long as the platform that can place the missile launching tower can use the Jie Ling anti-aircraft missile system; in the initial development, it was carried by the Hummer and the CM-31 armored vehicle for testing, and then the mass production model was carried by the TOYOTA DYNA truck. This also means that the Jaeling Missile itself does not have a storage device for projectiles in the vehicle, and the time required to reload the missile is quite time-consuming after it has been lit up. When the missile launch vehicle is engaged in combat, an ammunition vehicle will accompany the battle, and the vehicle can carry 12 Tianjian I missiles. It can be connected to the CS/MPQ-78 radar to enhance its system combat power. The CS/MPQ-78 radar can guide and control 2 ground guns and 4 missile launchers/cars at a time.

In order to enhance the ROC Armyís field air defense capabilities and launch the "War of Xinjiang" mobile deployment of air defense missile force on Taiping Island, the Army previously commissioned the Chinese Academy of Sciences to develop an extended-range Sword-missile field air defense missile system based on the Jianyi missile Sword Shadow Project. Because Taiping Island is about 13 kilometers away from Vietnamís Dun Qian Sand Bar, this air defense missile system must cover the sea and air area of Vietnamís Dun Qian Sand Bar, and the range must be increased from the 9 kilometers of the existing Jian Yi missile to more than 13 kilometers. This air defense missile system is mainly equipped with a guide in the Jianyi missile.

In the event of heavy rain or bad weather, after the target is locked by the radar, it will be guided by the radar first after launch, and the terminal uses infrared to lock the target. Destroy; the missile itself also has the capability of identifying friend or foe, electronic countermeasures and infrared countermeasures, and can operate at night. However, the Armyís AH-64 Apache helicopter and UH-60 Black Hawk helicopter occupies most of the budget. Under the budget, it decided not to continue. But then by the Ministry of National Defense on the overall assessment of the armed forces general missiles, the Republic of China Navy considered quite suitable for deployment in Kangding class frigates which can replace the old MIM-72 / M48 missiles.
