David Crane at Defense Review has a first-hand report on this bad boy from the International SOF Week 2005/APBI (Advanced Planning Briefing to Industry) show.
The MGL-140 40mm grenade launcher, manufactured by Milkor USA, is specifically designed to fire a new family of advanced and, in some cases, hyper-lethal LI/LV 40mm munitions manufactured by Martin Electronics, Inc. (MEI), in addition to all currently-available NATO-spec lethal and non-lethal/less-lethal munitions.
With regard to the MEI munitions, this new advanced low impulse/low-velocity 40mm ammo family utilizes a longer projectile for greatly enhanced lethality (in two of it’s incarnations). The MGL-140 will fire six rounds of these unique munitions in 3 seconds at ranges up to 400 meters (437.6 yards) and effectively covering a minimum destruction area/zone of 20×60 meters. Or, the weapon can engage specific targets with pinpoint accuracy at up to 150 meters.
He also details some of this new 40mm ammo in a long, fact-filled post. And he’s got a bunch of high-res pics. Go read and look.
