An enormous projection system has formed the basis of an ultra-realistic simulator at the Royal Navy’s training base at HMS Collingwood in Fareham.

The projection system is part of the Close Range Weapon Trainer at the unit, which allows all of the sailors and marines training at the base to learn crucial weapons skills.

Commander Pincher Martin from HMS Collingwood told the Portsmouth News that there are four separate rooms containing general-purpose machine guns, cannons and mini-guns that work with the projections to create a very realistic attack situation.

“Ultimately, for all our sailors and marines it’s important they learn the basics,” Commander Martin said. “Now we can put them under duress and the standard operating procedures become standard practice. God forbid they do ever have to use these skills for real, but if it does happen they will be able to just carry it out naturally and it will be second nature.”

And it is not just the projectors and the arms that lend the rooms their realism. The unit has installed two moving platforms mounted with machine guns, which make the floor move in the same way as it would on a ship at sea.
