- BILL 2 Anti-tank guided weapon
The BILL 2 Anti-Tank Guided Weapon is a man-portable or
vehicle -mounted guidedanti-tank missile using theoverfly top attack method to attack the weaker parts of anarmoured vehicle . The weapon is currently in service with theSwedish Army .ystem
Design
The BILL 2 was designed upon the original
BILL 1 Anti-tank guided weapon that has been in the service of theSwedish Army since 1988. The BILL 2 is currently produced bySaab Bofors Dynamics , who are located inKarlskoga ,Sweden . The BILL 2 comes with one 10.5kg missile, a launching tube,tripod with x7 magnification day sight, and onethermal imaging sight.Operation
The BILL 2 uses OTA or
Overfly Top Attack to attack its target. What this mean is that the missile flies on a standard horizontaltrajectory , with the difference being that instead of directly hitting the target head on, it overflies it, detonating its warheads on top of an armored vehicle, where thearmour is usually lighter. It also utilizes new guidance accuracy via the installed rategyro , which monitors the tracking movement of the launcher. It is designed primarily to attack armoured or unarmoured vehicles, but can be used to attackhelicopter s 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 four 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 wire. 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 aproximity fuse and an inertial impact fuse. The BILL 2 is armed with a double vertically strikingshaped charge , which is a HE orhigh-explosive warhead. The front warhead destroys thereactive armour and leaves the rear warhead to penetrate the armour. The charges are shaped to direct all of the hot fragments to one point on the vehicle.Operators
