The MajorMod™ is a medium weight, explosively driven, water disruptor for use against medium sized IEDs such as fire extinguishers.

It shares the same form and geometry as an MLVD™ module but is half the length, making it the ideal disruptor for mounting on a mini ROV or for carrying on the person. The loaded charge weighs four kilogrammes (9 lb).

The MajorMod™ uses patented technology for producing a shaped charge using sheet explosive or detonating cord as the propellant and water as the projectile. Each module consists of two containers; a tamper and a projectile, which are fitted together, sandwiching the explosive charge. Endcaps hold the elements together and allow separate modules to be joined side-by-side or end-to-end according to the size and shape of the target.
