V-hull

The design originated in the 1970s with vehicles such as the Casspir used extensively during the South African Border War, Leopard security vehicle[1] used in the Rhodesian Bush War[2] and South African armored vehicle company Land Systems OMCs and Buffels.

[3] The purpose of V-hulls is to increase vehicle and crew survivability by deflecting an upward directed blast from a landmine (or Improvised Explosive Device) away from the vehicle, while also presenting a sloped armor face.

[4][5] By presenting its armor at an angle, it increases the amount of material a ballistic projectile must pass through in order to penetrate the vehicle, and increases the chance of deflection.

V-hulls are incorporated in armored vehicle designs in several different ways.

Many vehicles, such as the BAE Systems RG-33 incorporate the V-hull into a monocoque chassis, while others, such as the ATF Dingo and International MaxxPro use a body-on-frame chassis, with an armored V-hull crew compartment, and an additional V or semicircular shaped piece protecting the driveline.
