Operation

The BILL 2 uses OTA or Overfly Top Attack to attack its target. The missile flies towards the target on a standard horizontal trajectory

A trajectory is the path that a moving object follows through space as a function of time. The object might be a projectile or a satellite, for example. It thus includes the meaning of orbit—the path of a planet, an asteroid or a comet as it travels around a central mass...

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 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

 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 a proximity fuse and an inertial impact fuse. The BILL 2 is armed with a double vertically striking shaped charge
