The FB40 is a proximity fuze for 40mm L70 HE and PFF ammunition. It was designed to defeat aircrafts, missiles and small boattargets. A point detonating function allows touse the fuze against hard target.

 

 

The FB40 fuze was designed in accordance with STANAG 4187 and developed and testedin accordance with the criteria of MIL-STD-331. This fuze ensures optimum performance against all land and naval targets. Two operating modes are selectable electrically at the time of firing:

• Proximity + Point detonating + Self-destruction. The FB40 fuze is set to initiate detonation when proximity with the target is detected. Point detonating function is provided as backup,in event of direct hit. Self-destruction is activated if neither of the above conditions occurs.

• Point detonating. This functioning mode can be selected for hard targets engagement. In this mode proximity and self-destruction are inhibited, and only impact can activate detonation.
