The LVTP-5 was an evolution of the LVT-1 to LVT-4 World War II-era landing vehicle tracked series, but was considerably larger and could carry 30-34 combat-armed troops.

The most common type was the LVTP-5, an armored personnel carrier, with mine-sweeper, command, recovery and fire support variants, the latter mounted a 105 mm howitzer.

As of the mid-2010s, the sole remaining state user of the LVTH-6 was the Philippines, who used four of them for their naval infantry force.
