BACKGROUND

Rheinmetall Waffe Munition GmbH offers

several 40 mm High Velocity (HV) rounds

Warheads

High Explosive (HE)

High Explosive Dual Purpose (HEDP)

Fuzes

Point Detonating (PD)

Air Burst Munition (ABM)


• How?: Performances

• Which?: Preferred warhead for 40 mm HV ABM

• What?: Added value of ABM

TNO ASSIGNMENT


Provide insights into the added value of an AB fuze compared to PD fuze

Support selection of best suited warhead against selected target set for a 40 mm HV ABM round

CONCLUSIONS

The 40 mm HE warhead displays a higher lethality than the 40 mm HEDP

against various human targets making it the better option

The munition is 5 times more effective using the AB Fuze than PD fuze

Added value of the ABM fuze has been shown in a relevant military

operational context


TNO provides the competitive edge for your product development!
