The 4.5-inch (114 mm) M8 fin-stabilised rocket is approximately 33 in (0.83 m) in length and 40 lb (18.1 kg) and is almost an equivalent of a 105 mm Shell M1. This rocket utilises an M4 fuse which explodes after a 0.015-sec delay set off by auxiliary M1 booster.
The components of the rocket break down into three separate sections, the fuse, shell and motor body. The shell of the rocket or the head is made up of a warhead body fitted with a burster tube. The burster tube itself extends from the shell through the rocket body and through the rocket motor, the purpose of this is to expand the explosive capability of the rocket by utilising the rocket motor as an additional source of fragmentation in the explosion. Once fired, folding fins around the tail flange will extend and spin-stabilise the rocket.
The M8 rocket requires a tube launcher to launch (as opposed to being installed directly to external hardpoints) and this is accomplished by mounting an M10 cluster launcher to the underside of the aircraft's wings or fuselage belly. The M10 is a cluster of three 10-foot tubes manufactured from plastic (M14s are made from steel and M15s are constructed of magnesium alloy) and are banded together in six places and are secured to the aircraft via two mounting straps, front and rear. The rear strap also bears the electrical connections which link up to the rockets once in the tubes as the firing links. The release and contact mechanisms are protected from flying links and fired casings ejected from the wing guns to prevent accidental damage or drop release of the M10 launcher.

Tell us about the tactical and technical characteristics of the rocket.
The M8 rocket is a 40 lb (18.1 kg) high explosive mass with a TNT warhead which travels at 600 mph (970 km/h). After slamming into a target a slight delay will set off the explosive mass of the missile causing the TNT shell to detonate along with fragmenting the rocket body and motor. Damage is caused by both the high explosives and fragmentation.
Comparison with analogues
Give a comparative description of rockets that have firepower equal to this weapon.
Usage in battles
The M8 rockets are typically mounted on an aircraft in groups of three (usually two launchers of three) or a total of 16 on the boat Higgins 78 ft PT-200. The M8 rocket is typically best utilised against personnel, installations and light armoured vehicles due to the fantastic fragmentation of this rocket upon impact and explosion.
Pros and cons
- Lightweight, able to mount on fighter aircraft
- Can be used against bombers
- Inaccurate, best fired in groups to increase the chance of hitting a target
- Increases aerodynamic drag, decreasing flight efficiency
