Essentially, we've stuck the M777 ULFH (Ultra Light Field Howitzer, a brit-designed gun) on a light tracked chassis, and added robotics to reduce crew size.
Swedish Bikini Team's gun.
Archer is a self-propelled 155 mm artillery gun based on a commercial off-the-shelf chassis, originally made for construction equipment, allowing for a system that is both simple and inexpensive to maintain. The three-man crew - as opposed to the normal six to 10 - operates all activities through computers in the splinter-proof cab. Each gun carries shells required to perform its mission. An Archer gun provides the same operational capability as four to six traditional guns.If we aren't going to buy a domestic 155mm - how about a side-by-side shoot off?
