KETF key features(Kinetic Energy Time Fuse)

KETF principle

8




KETF principle

The Vo measurement of each round and adaptation of the fuse-time (compensation) according to the actual Vo will reduce the dispersion in depth significantly

Burst of 7 shots 35mm to a distance of 1.6 kmWithout muzzle velocity correction With muzzle velocity correction

Control the deployment of the sub-projectiles (distance to target)

9




KETF characteristics

Optimise payload for air defence, infantry fighting vehicles and RAM protection Small explosive charge opens the projectile body Due to the combination of projectile spin and velocity, the sub-projectiles

are ejected in a forward directed cone

~15°

Payload: Tungsten cylinders of;•35mm x 228 - 3.3g•35mm x 228 - 1.24g•30mm x 173 - 1.24g

KETF operational effectiveness vs aircraft

Projectiles programmed for airburst (burst of 3) Tungsten sub-projectiles perforated the outer skin

killing pilot and electronics inside

11




KETF operational effectiveness vs covered foxhole

Projectiles programmed for airburst Sub projectiles have been optimised for use against combatants Soldiers, weaponry and optics were killed

12




KETF operational Effectiveness vs commercial vehicle

Projectiles programmed for airburst (burst of 2) Sub-projectiles perforates the outer skin killing

internal components, driver and engine

13




KETF operational effectiveness vs main battle tank

1 Projectile programmed (air burst mode) to neutralize MBT All optical sights were hit and destroyed

25mm x 137 FAP ammunition for F-35ARequirement: One general purpose Non-DU 25mm round without explosives for both Air-to-Air and

Air-to-Ground employment Performance as defined in ORD (Operational Requirements Document): Ground targets incl. hard target (BMP 2 level) have to be defeated on long range (9000 FT)

for specific aircraft conditions Penetrator has also to be effective against soft targets
