What is the M28 link made of?
Phosphated steel
What is the maximum effective range of the M791?
2000m
What does the projectile of the M791 consist of?
Nose cap - Polyethylene
Sabot - Nylon
Penetrator - tungsten alloy
Windshield & base - Alluminium alloy
What is the minimum burn time of the tracer in the M791?
1.4sec
What is the propellant of the M791?
WC886 - double base
What is the fuze used in the M792?
M758 (HMX/PBXN-5 booster) Mechanical Point detonating
What is the main fill of the M792?
H761 HEI
What is the safe arming distance of the M792?
10m
What is the minimum self destruct time of the M792?
6.2 Sec
What is the length of the delay element on impact of the MP-T SD MK2?
0.3 m/s
What is the tracer burn time of the MP-t SD mk2?
5.3 secs
What happens when the MP-T SD MK2 impacts target?
On striking the target the aluminium nose cap is crushed and if sufficient velocity is generated by the rate of deformation, the incendiary composition will ignite. The heat and pressure generated by the incendiary composition detonates the HE which causes fragmentation of the steel body. The delay of 0.3 secs allows the projectile to penetrate the target before detonating/
