RB 15 M

The missile RBS 15 M is a heavy Ship-to-Ship missile system. The missiles have a considerable cruising range and are designed to engage combating warships and huge naval cargo carriers. The missile RB 15 M is the main weaponry on coastal corvettes such as HMS Stockholm, HMS Gothenburg and guided-missile watercraft of the HMS Norrköping class.


The RBS 15 M development work started in 1979 and the first production missile was delivered in 1984.

System description

The on-board missile system covers the following units:


Missiles with launching tubes

Missile Central Processing Unit (MCPU)

Transfer Box

Base Frame with power supply boxes.


Ship based units:


The Missile Central Processing Unit (MCPU), includes the control and firing boards, a bridge indicator and a computer unit. The assignment for the MCPU is to receive data from the ship’s command center, arm the missile and execute the firing of the missile.


The transfer box will communicate with all missiles afloat.


The base frame boxes provides the missile with an electrical supply


Missile tube

The missiles are stored in missile tubes on base frames, mounted on the ship deck. The firing tubes are equipped with dehumidifiers to ensure a favorable environment for the missiles afloat. The tubes also act as missile firings ramps. Each ship can carry a total of 8 missiles.



The homer:


The missile carries an interference free, active pulse radar homer with an agile changing frequency technique. The action of the homer and its target selection is chosen and programmed before the firing.


Control system

The automatic guidance system provides, besides the traditional flight orientations such as roll, tip and yaw and also the guidance on a pre-determined course right up to the homing phase. 


Compressed air system

For the operation of the rudder servos a compressed air system is used. Compressed air is also used to extend the wings and for pressuring the fuel system of the turbo jet engine.


Altimeter control

The missile can be set to different attack altitudes. The altimeter control measures the current altitude above the water surface and achieves lower altitude flight passes at pre-set positions in the approach area.


Logic Unit

In preparation for the missile firing the logic unit serves as a communication center between the MCPU and the missile. The logic unit automatically starts a self-test run prior to the missile firing and activates the pyrotechnical and pneumatic units. The preparation data from the MCPU are stored in the logic unit, which generates logic signals for the different sub-systems of the missile during the missile flight.



The missile is fired by two powder booster rockets. These separate from the missile after approx. 3 seconds. During the acceleration the missile main turbo-jet engine starts and subsequently takes over the propulsion.



The warhead is designed to be very effective against sophisticated targets.


Operational description


After the start-up of the missile, and while in the stand-by mode of the gyro- and the electrical systems, an automatic self-test run is made.


In preparation for the missile firing data are transmitted from the MCPU unit to the missile.


The doors open, the battery and compressed air system are activated and the powder initiators receive voltage.


After the missile has left the firing tube the wings are extended and the turbo-jet engine starts.


The automatic guidance then begins controlling the missile.


The approach

The missile veers on a pre-set bearing towards the target area and starts the approach at the chosen altitude. The following flight altitude is then determined by the below dwelling archipelago terrain and the distance to the target. This gives the advantage of firing the missile from a sheltered position far inside the archipelago.


At a certain distance the homing device is activated. Target acquisition and target locking take place, when all the pre-programmed conditions are fulfilled. The missile approaches the target at the lowest possible altitude. This altitude is maintained until the explosion of the warhead at the target.
