MUSS - Multifunctional Self-Protection

In service self-protection system for armoured vehicles


  • MUSS Sensor Head
  • Anti-tank Guided Missile Warning Sensor
  • Laser Warning Sensor
  • MUSS Central Electronics
  • MUSS Countermeasure IR-Jammer
  • MUSS Smoke Electronics
  • Adjustable Smoke Dispenser
  • MUSS Pyrotechnic Ammunition



The MUSS system is designed to counter threats causedby ATGM (anti-tank guided-missiles) and laser guided ammunition in six steps:

1. The scenario is continuously monitored by the MUSS passive sensor heads. It recognizes threats with their emitting radiations through the warning sensors.

2. Based on the threat messages which include direction of attack and other parameters, this is then displayed to the vehicle crew.

3. The movement information of the vehicle and the head sensors is collected by the IMU and provided to the MCE.

4. The appropriate type of countermeasures will be automatically selected. The countermeasures are initiated automatically or semi-automatically as selected by the vehicle crew.

5. The Jammer is able to disrupt the guidance of most of the jammable ATGMs which are currently in service. This function influences the missile in such a way that it does not reach its target, either hitting the ground or flying away.

6. A further countermeasure is the deployment of a special smoke grenade activated by the turnable smoke screen dispenser.


  • Configured to effectively protect armoured fighting vehicles against guided ammunition such as Missiles and Laser guided munitions
  • IR Jammer countermeasure is effective against:
    • Wire guided optically tracked non-jam-resistant missiles
    • It is non consumable, so it becomes re-usable
  • Pyrotechnic munition counter measure effective against:
    • Jam-resistant second generation missiles
    • Third generation missiles (e.g. guided by IR-Seeker)
    • Laser Target Designator guided missiles
    • Laser Target Designator guided munitions
  • No significant influence on vehicle radiation
    • Passive sensors (UV-MWS and LWS)
    • I R Jammer short activation time, not detectable either in visible or in thermal image spectrum
  • Multi threat capability
  • No collateral damage (as with hard kill DAS)

Main Benefits

Presently the protection of armoured fighting vehicles is based on traditional protection made of steel or composite materials. The level of protection has mainly been improved by providing thicker armour with the consequence of increasing weight. The requirement of the weight budget for the Puma Armoured Infantry Fighting Vehicle (AIFV) is very limited. Under such conditions, the level of protection cannot be achieved when using only passive armour.

It is only possible to improve the level of an Armoured Infantry Fighting Vehicle's protection within the given weight limitations by using an active protection system approach. Hits from hostile ATGM threats can be avoided by combining warning sensors, which detect the missile and laser threats, and activate the appropriate countermeasures.
