The ARWEN 37 (ARWEN stands for Anti Riot Weapon Enfield) is a British non-lethal launcher.

HistoryEdit

The ARWEN 37 was designed in 1977 by RSAF Enfield after a request by British law enforcement for a multi-shot weapon to replace the single-shot Federal Riot Gun. Three prototypes were developed for testing; a magazine-fed, semi-automatic prototype, a rotary cylinder prototype, and a pump-action prototype. The rotary cylinder prototype won and began production in the early 1980s.

As of the year 2001, all of the ARWEN trademarks and patents are owned by Police Ordnance Company Inc. The weapon is manufactured under license in Canada.

Design DetailsEdit

The gas-operated ARWEN has a five-round rotary cylinder, which is easily accessible for reloading as opposed to the break-open barrels seen in single-shot launchers. This, combined with the weapon's repeat-fire nature, improved its rate of fire, particularly when needing the user to lay down a protective wall of anti-riot ordnance on advancing mobs.

VariantsEdit

  • ARWEN ACE - Single-shot, breech-loaded model which fires specialized smoke and baton rounds
  • ARWEN Multi-S - Short-ranged variant with no stock and a shortened barrel
  • ARWEN 37 Multi-V - Vehicle-mounted variation
  • ARWEN 37 Mark III - Modernized version featuring a rifled barrel, A37-AM4 tactical mounts, and numerous other features.

AmmunitionEdit

The weapon uses a special type of 37mm round with a rebated rim on its case. The round has a total of nine variants:

  • KO1 - Standard impact baton
  • KO2 - CS smoke
  • KO3 - Irritant impact baton
  • KO4 - White/colored screening smoke
  • KO5 - Barricade penetrating irritant
  • KO6 - Muzzle blast irritant
  • KO7 - Multi-ball area impact round
  • KO8 - Soft-tip impact baton
  • KO9 - Sub-caliber training/marking round
