The watertight rear plug of the rocket container is removed just before firing, which closes the firing circuit and allows the rocket to be fired. The rocket is propelled by a large number of long sticks of tubular propellant that produce a constant pressure while burning, providing constant acceleration. The engine burns out before the rocket leaves the launcher at a velocity of approximately 300 metres per second. As soon as the rocket leaves the launcher, nine fins fold backwards from the rear. These fins provide stability for the rocket while it is in flight. There are two safeties. The first is a bore-riding pin located mid-body of the projectile that blocks the warhead firing circuit. After the projectile leaves the tube, the bore-riding pin falls out releasing the second safety which prevents detonation until the rocket has traveled at least 10 metres from the launcher. The rocket reaches a range of 330 metres in about 1.25 seconds, and 360 metres in 1.36 seconds.
