System


Design

The RBS 56B BILL 2 was designed upon the original
BILL 1 Anti-tank guided weapon The RBS 56 BILL is a Swedish manportable SACLOS wire-guided anti-tank missile developed by AB Bofors. Development began in 1979 and entered production in 1985. The Swedish Army began receiving the missile in March 1988. BILL stands for (Bofors, ...

since 1988. The BILL 2 is currently produced by Saab Bofors Dynamics, who are located in Karlskoga, Sweden. The BILL 2 comes with one 10.5 kg missile, a launching tube, tripod with x7 magnification day sight, and one thermal imaging sight.


Operation

The RBS 56B BILL 2 uses OTA or

to attack its target. The missile flies towards the target on a standard horizontal trajectory, but rather than directly hitting the target head on, it overflies it, detonating its warhead on top of an armored vehicle, where the

is usually lighter. It also utilizes additional guidance accuracy via the installed rate gyro, which monitors the tracking movement of the launcher. It is designed primarily to attack armoured or unarmoured vehicles, but can also be used to attack helicopters or soft ground targets, such as light buildings. The BILL 2 can be mounted onto a variety of vehicles and then fired remotely from inside the vehicle.


Firing Modes

The BILL 2 has three firing modes that the launcher's operator can select, before launching the missile. * Basic – In this mode the missile will use both of its sensors to hit the armoured vehicle from the top. * Non-Armored – In this mode the missile uses no sensors and flies on a LOS or line-of-sight, while using the impact fuse. * Soft Target – In this mode the optical sensor is used, but the magnetic sensor is not. The missile then uses OTA to attack its target.


Missile

The BILL 2 Missile uses a SACLOS or semi-automatic command to line-of-sight guidance system, and is controlled via a communications wire that trails behind the missile from the launch tube. The BILL 2 warhead has an optical and magnetic sensor. The optical sensor serves to find the target's range, while the magnetic sensor detects metallic targets to determine the best point for the missile to detonate. The BILL 2 contains both a proximity fuse and an inertial impact fuse. The BILL 2 is armed with a pair of vertically striking explosively formed penetrator warheads, which each direct a self-forging slug of metal downwards at extreme velocities using a high explosive blast. The 40mm frontal "precursor" warhead destroys any reactive armour protecting the target and leaves the 110mm rear warhead to penetrate the armour. Total penetration capabilities are classified, but are known to be at least 550mm in rolled homogeneous armor.
