Proven: Ukraine uses 155mm BONUS anti-tank shells with spaceship tech

KYIV, UKRAINE — Photos of debris from the Franco-Danish 155 BONUS anti-tank artillery rounds have surfaced on the web. The main comment on the shared photos is that they prove the delivery of ammunition to Ukraine. This is the first evidence that Ukraine is operating with them on the front.

155 BONUS is extremely accurate anti-tank ammunition. They were developed as a result of a cluster agreement between the companies Bofors of Sweden and Nexter of France. This munition is characterized by carrying two top-attack EFP submunitions.

EFP and LIDAR

An EFP or explosively formed penetrator, also known as a self-forging warhead, uses a profiled projectile. This projectile has a much greater penetration efficiency on the armor of the enemy vehicle. Also, the Bofors/Nexter 155 BONUS is a very precise weapon as it finds its targets using three multiband IR sensors and LIDAR.

LIDAR is a light detection technology. This method measures the distance between an enemy object using a laser that calculates the destination to the object by the speed at which reflected light from the enemy object is returned to the device. This method is also known as 3D scanning.

LIDAR is a completely new technology that is used in the navigation control of autonomous flying vehicles and their flights over Mars.

How does BONUS work?

The operating principle of the Bofors/Nexter 155 BONUS is as follows: After setting range and target profile[s], the BONUS round is fired from a standard rifled 155mm artillery tube. The round flies on a parabolic arc, with a range of up to 35 kilometers [21.7 mi]. A timer fuse ignites a small ejector rocket in the nose, which drags the two submunitions out of the shell casing over the target area.

Once clear of the shell, the submunitions fall towards the target. The shell and the nose assembly fell away. The submunitions deploy winglets, and independently corkscrew down over the subject area at 900 rpm, scanning for targets. Once a submunition detects a target vehicle beneath it, it detonates its explosive payload, creating an explosively formed projectile that strikes the target vehicle’s weak top armor. The high-velocity impactor penetrates the hull and kills or wounds the crew.

There are at least two other similar munitions in the world that use similar technologies to the Bofors/Nexter 155 BONUS. One is the German SMArt 155 ammunition, while the other is the American M898 SADARM. The Bofos/Nexter 155 BONUS is in service in several countries: France, Sweden, Finland, the USA, Norway, and, as it became clear, Ukraine.
