Jianyi / Antelope - Design

Tianjian I missile is an air defense weapon developed by Taiwan. It was originally an air-to-air missile, mounted on IDF and F-5E fighters. It has been in service in Taiwan's air force for many years and has undergone many air launches to verify its effectiveness. The vehicle-mounted Jianyi air defense missile system modified the original air-launched Jianyi missile into a ground-to-air air defense missile, centered on the Jianyi missile, equipped with mobile vehicles, reconnaissance radar systems, and control systems. With communication systems this forms a field air defense system which can be independently engaged or cooperate with other ground air defense systems to form a regional air defense system to defend important institutions or facilities, such as command centers, airports, ports, etc.

The vehicle-mounted Jianyi air defense missile system is very convenient in its operation. It can be operated by the shooter, the tracker and the squad leader and driver. When the system enters the tactical position, the tracker will start the generator first. Remove the safety latches of the shooting tower and missiles; at the same time, the shooter moves the control display to the selected remote control operation position, and then starts the system power supply temperature controller. The tracker sets up the sight sight and executes the calibration procedure of the sight sight. After the warming machine is completed, the system enters the combat readiness state.

The CS/MPQ-78 is a mobile fire control radar, which can be incorporated with both gun and missile to execute low altitude air defense missions. The CS/MPQ-78 short-range air defense fire control radar developed by the Chungshan Institute of Science and Technology is composed of a search radar, a track radar and a photoelectric monitor. The search and track radars cover both medium-altitude and low- altitude air space, with a distance precision accuracy of around 10 meters. Its fire control system, combined with 35mm and 40mm rapid-fire guns and land-based Sky Sword I air defense missile, can offer an adequate short-range air defense; and it has a multiple anti-jamming function.

When the shooter receives the command of the shooting commander and completes the range and distance of the guard zone, he can enter the engagement state. At this time, the system will search and identify enemy aircraft according to the set area. The control computer will display the enemy aircraft information in the alert area on the control screen as a reference for interception. The system will also automatically control the tower to track the target, and the missile finder will lock the target and be ready to launch at any time. When the system radar and the missile finder both lock the target, the system missile sound (MISSILE TONE) will send out the lock sound (ENGAGE TONE) to inform the shooter, the shooter only needs to press the unlock button, even if the missile enters the tracking and ready-to-launch state. Finally, press the shooting button to complete the entire engagement process.

In addition, during the operation of the system, the control system will calculate the range of the missile at any time and report the status of the whole system to the command center by radio or wire, so that the commander can grasp the battle situation.

The functions of the vehicle-mounted Jianyi air defense missile system are as follows:

  • Capable of night combat.
