SWE - RBS-56 "BILL"

RBS - 56 BILL
BILL - (Bofors Infantry Light and Lethal - translates to: Bofors Light Infantry Lethal Weapon). This PTRK is a new type, which is designed to destroy targets not only frontally, but also from above (the so-called "TOP ATTACK" system). It is a new concept that brings new possibilities for the use of PTRS on the current battlefield. This system was introduced into the Swedish arsenal in 1988.


Advantages of using the "TOP ATTACK" system:
- larger target area that can be hit
- the tops of armour of armoured vehicles are thinner than, for example
frontal:
(a) the largest part consists of armour with a thickness of 10 to 200 mm
(b) the second part is armour between 200 and 300 mm thick


- the target can be destroyed when:


(a) standing on open ground
(b) moving on level or rugged terrain
(c) it is in a trench, in cover


Characteristics of the PTRS BILL and principle of use:
The PTRS BILL is a low-flying missile with a converging and impact fuze. The proximity fuze can be disconnected, leaving only the impact fuze in operation, which is used to directly destroy targets in specific cases to destroy field fortifications, helicopters...
The missile is guided semi-automatically after the deliberate, with the difference that shortly after firing from the container (launcher case, launcher) it is automatically guided to the flight level, approximately 0.75 m above the deliberate. The position of the missile in the air is evaluated by a laser beam emitted from the PTRS. The missile does not rotate, which is ensured by the gyroscopic on-board system. The cumulative warhead is located in the centre of the missile upstream of the flight engine and is inclined 30 degrees downwards from the longitudinal axis of the missile. The gunner-operator can select the auto-guidance mode for flight over the target or the direct hit mode. At launch, the gas generator at the rear of the launcher case grants the missile a small initial velocity (72 m/s), which is increased by the flight engine up to 250 m/s.


PTRK main parts:
- tripod
- day sight
- night sight
- firing case
- missile:
(a) warhead - impact fuze
- proximity fuze
- cumulative charge
(b) wing section ( with optical convergence sensor
igniter)
(c) jet engine
(d) logic unit
