impact fuze
contact fuze
percussion fuze
direct-action fuze

For the HE projectile an impact fuze was fitted in the nose of the bomb.

The missile's blast fragmentation warhead is triggered by an impact fuze requiring a direct hit.

The fuze was a mechanical impact fuze on a 38 inch nose spike.

Two rounds were developed, a high explosive round with an impact fuze, and an armour piercing round.

A nose impact fuze.

It consists of a steel body containing a solid fuel rocket, and a high explosive warhead with a mechanical impact fuze.

On the outside of the device were "vanes"; the vanes created a spin which armed the impact fuze.

A base impact fuze screwed into the rear of a projectile to protect the fuze during impact.

If the impact fuze has not triggered the grenade after 3.2 to 4.2 seconds a second pyrotechnic delay triggers the grenade.

Warheads are typically detonated by a proximity fuze or by an impact fuze if it scores a direct hit.

The warhead is a 3 kg penetrating hit-to-kill warhead type with an impact fuze and a self-destruct timer.

It has the same statistics and markings as the M67 except it has a red-painted fuse and lever to indicate it has an impact fuze.

The UDZS fuze has both impact and time delay functions, the impact fuze arms after a pyrotechnic delay of 1 to 1.8 seconds.

HE-T and HE-I shells are used and fitted with a A-670 time and impact fuze which includes an arming delay and self destruct mechanism.

Only minor changes were required to make it an air-to-surface missile, the size of the warhead was increased as a result of replacing the large proximity fuze with a simple impact fuze.

The mortar could fire two types of shell, a heavy armour piercing shell with a delayed action fuse weighing 384 kg, and a lighter 287 kg shell fitted with an impact fuze.

The target is usually destroyed or damaged by means of an explosive warhead, often throwing out fragments to increase the lethal radius, typically detonated by a proximity fuze (or impact fuze if it scores a direct hit).

The US Army also tested a plastic chemiluminescent grenade in 1966, utilizing the PB-155 filler and the M217 impact fuze, with negative results about the mixture's usefulness for the intended role, with the brightness and duration of functioning being "insufficient".
