LVTP-7 is an amphibious assault vehicle developed by American FMC (now BAE Systems) in 1972. It is an improved version of the LVT-3C which was used as the main landing vehicle during the World War II. The water jet propellers installed increased the speed at sea and the body was made out of special aluminum that made it lighter but protective force increased. It is also possible to rotate 360 degrees on land and sea. In 1974, the ROK Marine Corps imported the LVTP-7 from the US and used it for amphibious landing operations until the introduction of the LVTP-7A1, which improved driving performance and protection in 1985.
