TYPE 1988 "HEBIMARU"
* OVERVIEW:
Type 1988 "HEBIMARU" (Snake Ring) is a short range surface to air defence system designed to protect brigade level units against enemy aviation, helicopters, cruise missiles and UAVs. This particular incarnation of "Hebimaru" is a modern upgrade of old system, adding an upgraded radar, new version of missiles, and additional linking capabilities.
- A Type 1988 battery is built around a Type 1988-V command post. Up to four "Hebimarus" ehicles can be controlled by a single Type 1988-V command post.
- Type 1988-V command post is a battery command post mounted on a vehicle chasis, providing command & control to a Hebimaru battery, as well as incorporating air surveillance radar & advanced algorithms for threat evaluations and fire management. It also permits linking with other Nifonese air defence systems through SHOGUN battlefield management system. A single Type 1988-V command post can control up to 6 Type 1988 vehicles, including remotely controlling them and assigning them targets.
- Type 1988-V vehicle is fitted with a single Ta-Ki 13 Mark 7 radar - a short range X-band AESA beam forming 3D surveilance system. Light enough to be mounted on a pickup, Ta-Ki 13 Mark 7 can detect targets flying at high altitude at distance of 75 kilometers and continuously track over 100 targets.
- The system is crewed by 4 men - commander, driver, gunner and radar operator.
- In the picture, Type 1988, is mounted on a 6x6 1981 vehicle, but on client's demands there is exist option of installating the Hebimaru turret on chassis of choice.
* GUN:
- Type 1988 is fitted with a single 43x362 mm L67 anti aircraft gun designated "Anti Aicraft Gun 43mm Type 1955".
- "Anti Aicraft Gun 43mm Type 1955" weights 2500 kg.
- Average round weight is 1kg.
- The mode of operation is gas - operated. The cannon possesses a rate of fire of 380 RPM, with muzzle velocity of 1000 m/s.
- The gun is chain fed, eliminating problems caused by magazines.
- Recent increase in capability comes in form of a new " Anti Air Cartridge Type 2016" - an airbrust round. The round is equipped with a smart fuse, which measures relevant factors and detonates on a pre-set distance. Upon detonation a swarm of tungsten pellets is released, damaging everything in the area. While a single pellet causes minuscule damage, their sheer is sufficient to shred to pieces any given target. This kind of ammunition is resistant to electronic warfare.
- The vehicle carries 600 rounds to the main gun.
* MISSILES:
- "X8" is the main short range surface to air missile employed by this system. 12 such missiles are included, stored in containers which reduces impact of the environment and easies maintenance.
- "X8" is a two part missile, composed of the rocket itself, and the booster.
- The booster has a diameter of 175mm and annual trust of 30 kN. Once activated it speeds up the missile to speed of 1300 m/s in 2,5 seconds.
- After the maximum speed is reached, the booster is ejected and the main part of the missile continues flight on it's own. The main part does not posses a rocket engine, hence it's ability to manoeuvre depends purely on it's lifting areas. Hence the main missile was fitted with two large (315mm length, 90mm diameter for the rear set) sets of rudders, with rear rudders being X-shaped, while the front rudders are + - shaped.
- Total mass of the missile is 75 kg, with 30 kg being fuel.
- To reduce costs, the "X8" is fitted with a terminal semi active homing mode of guidance. During the earlier part of the flight, the missile flies on inertial guidance, using a gimbal ring coupled with GPS. During the final phase of approach, the semi active homing is activated. The missile's flight path can be updated via datalink. Such a mode of guidance makes detection of the missile itself impossible, but it's weakness is that the guiding station can be detected when operating.
- The system can effectively engage targets up to 15 kilometres away from the launcher, flying up to 8 000 meters.
* COMMAND & CONTROL:
- Each vehicle is fitted with fire control radar, operating on J-band, capable of tracking targets up to 20 km away. The radar can track 60 targets and engage 2 simultaneously.
- Linked to the radar is a CCTV optronic unit, IR unit and a laser rangefinder, each with reach of about 6 000 meters.
- Linking to "SHOGUN" battlefield management system provides IADS capability.
