The U.S. Army Wants to Put Big Guns on Small Tanks
Combat Vehicle Modernization Strategy[/a] as a way to bring large caliber cannon technology to lightweight vehicles. This technology is called RAVEN, which stands for Rarefaction Wave Gun.
Technology of Tanks, from Jane’s, is that a vehicle needs to weigh about one ton for every nine hundred newtons of force exerted on it. This means for the current 120-millimeter M256 cannon shooting a M829A3 Anti-Tank Shell,
. This is greater than the weight of America’s last canceled light tank, the M8 Buford. RAVEN technology cuts down on recoil significantly (
, in theory) with the way that it vents, allowing for cannons of the same power factor to be mounted on light vehicles.
Disadvantages to RAVEN technology is the need for the gun to vent gas backwards. Similar to recoilless rifles, this limits the proximity in which infantry would be able to operate around an armored vehicle. It also would limit angles of elevation: a vehicle that allowed a RAVEN gun to elevate too high might suffer damage from the blast going onto its deck. The need for a new loading mechanism for RAVEN guns is another engineering challenge. The 105-millimeter RAVEN demonstrator had a swinging chamber that accepted rounds from a carousel autoloader, but this isn’t similar to any setup on existing American tanks. Vehicles would have to be designed for RAVEN from the ground up, or undergo a very lengthy retrofit process to implement this technology.
Overall, RAVEN guns present an interesting, high-caliber armament option that could provide America’s next generation of light vehicles the firepower they need to overmatch any current and future threat. While the technology is not yet mature, it is based squarely on concepts already understood and developed.
