Based on the RBS-56 BILL system, Bofors has developed a new version known as the BILL 2, which is designed to counter the most advanced tanks and armoured vehicles, both current and under development. Externally, the BILL 2 system is virtually identical to its predecessor. The primary difference from an operational deployment perspective lies primarily in the ability to destroy tanks with the additional dynamic protection of the main armor and the small dispersion of the missile in the target area. The modes of combat use are also different.

From the design point of view, the PTRK BILL 2:
- tripod ( tripod)
- control unit with attachable night and day sight
- launcher (missile launcher) with missile

The changes that have been made are mainly related to the missile. The use of a more compact electronic unit has made room for the installation of a second (tandem) cumulative charge, and the flight rocket motor has been moved closer to the centre of the missile.

The front of the missile contains:
- a proximity (non-contact) fuze
- impact igniter
- the flight engine and the first cumulative charge

The rear of the missile contains:
- the second part of the converging igniter
- the main cumulative charge
- battery power supply
- electronics block
- stabilizing gyroscope
- flash tracer
- coil with wound wire
- stabilisation and aerodynamic control surfaces

The combat part thus consists of two separate interactive cumulative charges. The front one, smaller, makes an angle of 102.5 degrees with the longitudinal axis of the missile ("rearward", in the direction of flight) and its main function is to disable the dynamic protection block of the main armour.

The rear main, cumulative charge is placed perpendicular to the longitudinal axis of the missile, i.e. it makes a 90 degree angle with the longitudinal axis. It is initiated by a very precise igniter with such a small time delay that its cumulative beam acts in practically the same place as the beam of the first charge, which disables the corresponding dynamic protection block and clears the way for this second charge to pierce the main armour. This system places high demands on the operation of the multi-channel proximity fuze.

The proximity fuze consists of three main modules:
- an active optical sensor, functioning as an active range finder to determine the distance of the missile from the target
- a magnetic sensor, which detects the presence of a magnetic trail typical of the target
- a target detection algorithm that composes the signals from both sensors and stores them in memory

Targeting and guidance system:
For the PTRK BILL 2, the same principle of semi-automatic homing after deliberate homing as in the previous version is used. The difference is that the guided missile is automatically guided to the flight level, for a pass at a height of 1.05 m above the target. After selecting the fuze and firing the guided missile, the gunner-operator operates the manual launcher to keep the centre of the sight crosshairs on the target at all times. The guided missile tracker, which is part of the sight, records the deviation of the missile trajectory from the intended trajectory. These signals are passed to a control computer in the sight, which calculates the appropriate trajectory correction commands that are passed down the wire to the missile.

For space surveillance and target acquisition, a sighting device is used whose field of view is 105 x 65 at seven times magnification. A night module containing a thermal imaging system can be attached to the top of the sight. This system can be used at night, but also in reduced visibility.

According to the manufacturer's data, the tracking and guidance system and the converging igniter are to be characterised by a high degree of resistance to various types of jammers. The targeting unit is resistant to irradiation by a powerful laser, the electronics of the system to electronic radiation. The guided missile can be fired through foliage and guided, over the water surface and does not mind even the immersion of the driver.

The PTRK BILL 2, went into series production in 1999. The RBS 56 BILL is introduced in the armaments of Sweden and Austria.
