The missile system RBS 90 is a surface-to-air unit, foremost intended for support to the Army forces. This missile system can also be used for rampart of i.g. Air Force basis. The system will resolve its assignments in daylight as well in darkness.


The anti-aircraft company RB 90 is included as a company together with two anti-aircraft companies RB 70 in an anti-aircraft battalion RB 70/90, which is an allocation unit.



During 1976 a draft was composed as a project to Tactical Technical Economical Ambition (PTTEA) and the studies began at Bofors and Ericsson in the years 76/77.The start of the development was planned for 78/79 but was postponed to 83/84. The missile was ordered in 1989 and the first production unit was delivered in1991. Final delivery of all materials took placed in 1995.


System description

An anti-aircraft company of RBS 90 consists of an intelligence unit and six firing units. In the intelligence unit is included the search radar PS-90, mounted on a cross-country truck Model 45.


The liaison material is installed in the cabin. The firing unit is transported on a tracked vehicle. The local search radar PS-91, the gunner’s tracking equipment, power supply and the liaison material are installed on the tracked vehicle 2081 for air- defence combat control. The sighting arrangement, mount, power unit, cables and missiles are transported on a tracked anti-aircraft vehicle 2082. The remaining material is transported on the tracked vehicle 206 and a tracked trailer 1922.



Missile 90 is a further development of the missile 70 with a more powerful motor that gives an extended cruising range and a more powerful warhead with an RSV charge (shaped charge).


The missile 70 can be launched from an RBS 90 launcher, as well as RBS 90 can be launched from a RBS 70 launcher.


Battle sequence

-   PS-90 discovers the targets that are analyzed in the assault assessment unit. The targets are then transferred in priority sequence to applicable firing units.


-   The firing unit searches for targets with PS-91 radar and its own found targets are analyzed together with the incoming targets in the assault assessment unit.


-   The most hazardous target is selected for combating and is transferred to the gunner and the sight turns in on the target. The sight holds a TV- and an IRV-camera (infrared vision) which pictures are alternatively presented to the gunner on a screen. When the gunner can see the target, he takes over and follows it manually with a small joystick.


-   To permit the gunner to fire a missile he requires that:

-   the target is possible to combat (automatic calculation)

-   an IK confirmation has not been received


After firing the missile it is the gunner’s duty to keep the cross-hairs on the target right up to impact point. In the firing unit a laser beam is generated and the beam sweeps horizontally and vertically around the aiming line. The missile uses the received laser beam to calculate its bearing in relation to the aiming line. The navigation electronics in the control unit converts the laser signal to electrical control signals for the control surfaces. The missile will then follow the aiming line all the way to the target impact. Initiation of the warhead is done by a proximity fuse or at a direct hit.
