BAMSE MSAM

AIR DEFENCE MISSILE SYSTEM

General

Bofors and the Swedish Government have signed a contract for the development of the BAMSE Air Defence System. Bofors will have total system responsibility. Full-scale development will continue until 1998. Series production will start around the turn of the century.
In Sweden, BAMSE will fill the gap above the altitude coverage of VSHORADS and SHORADS. There is a similar need in many other countries, where the SHORADS altitude coverage of about 6 km is not sufficient.

The system will have all-weather capability. The missile range and altitude coverage of approx. 15 km makes the system suitable for the protection of vital objects such as airbases, naval bases, HQ’s etc., as the missile range exceeds the electro-optical controlled weapon stand-off distance of aircraft. In cases where an attack missile is released from an aircraft outside the range of the air defence system, it will still be capable of defeating the attacking missile.

The BAMSE System will also be ideal for the protection of mobile army units. This is due to the high system mobility and the short time required for redeployment and preparation to fire.

The altitude coverage of the system will exceed the altitude from which attacking aircraft normally operate. This together with the large surface coverage of the missile will ensure its successful defence of large areas.

The BAMSE System is air transportable and has the following features:

  • All-weather capacity
  • Mach 3 missile
  • Capable of defeating:
    -Stand-off weapons
    -Fighter/bombers
    -Bombers
  • High-level ECM protection
  • High saturation threshold

All this can be achieved at a very competitive price, which makes BAMSE unique in defeating high altitude and stand-off threats at a much lower cost than other air defence systems.

Combat Control

A battery of the system basically comprises a Surveillance Coordination Centre (SCC) and three Missile Control Centres (MCCs).
The central surveillance radar ( developed by Ericsson Microwave Systems AB) and the SCC constitute one unit. It has the characteristic 12 m high antenna mast which enables it to operate over terrain obstacles. The signal processing will be extremely advanced and the 3D-radar will measure the range and bearing to the target as well as the altitude of the target. The SCC will be compatible with the MCC, with automatic tracking and threat evaluation. It will also control other types of air defence systems.

The MCCs are connected to the SCC by cable or radio communication. The distance to the SCC can vary, but 10 km can be regarded as the standard distance. Up to four MCCs can be connected to an SCC. The distance between two missile vehicles can be up to approx 20 km.

The main communication system is radio. To ensure a reliable communication link the Swedish Army’s tactical communication system (TS 9000) is used, which has a large degree of jamming resistance. Other measures are also taken in order to safeguard the communication link.

Missile Control Centre

An MCC contains all the essential elements for the target engagement function. The MCC is towed by a cross-country vehicle which also transports the missiles. Deployment can be carried out in a few minutes.
An elevatable mast on the roof of the MCC raises the fire control radar, TV and IFF sensors. Guidance of the missile in trajectory is carried out by the fire control radar which is a further development of Ericssons Eagle radar and operates on the Ka band.

The capability of the MCC to acquire and track low-flying targets is considerably improved by the fact that it is possible to look over obstacles near the place of deployment. Target acquisition and tracking are initiated from the SCC by target assignment.

The missile fire control presents the relevant data to the two operators. Events happen very quickly in air defence combat and it is therefore essential that the operators are provided with fully comprehensive support to make optimal use of the system.

The missiles are fired from a stand, holding four missiles, located on the roof of the MCC. Reloading will take no more than a few minutes.

A short flight time to the target is very important for an air defence system. Reducing the flight time makes it more difficult for the enemy to avoid being hit. The risk of the line of sight to the target being interrupted is also reduced. High acceleration and subsequent maintained high velocity result in short flight times, even at long ranges. The missile will maintain its high manoeuverability right up to the range limit.

The high velocity missile has a prefragmented warhead which will be detonated by a proximity fuze, providing high effect on all types of aerial targets, from small, high velocity targets such as missiles and RPVs to large low-speed targets such as transport aircraft.

The BAMSE System will have integrated simulators and recording equipment which means that training operations, from system handling by operators to combat training of complete units, will be carried out without firing any missiles.
