Variants

• LVTP-7: Original series introduced from 1972. Originally armed with a M-85 .50cal machine gun and Mk-19 Grenade launcher.
• LVTP-7A1: 1982 upgraded. Renamed to AAVP-7A1 from 1984.
• AAVP-7A1 (Personnel): This is the most common AAV, as it carries a turret equipped with an M2HB .50 caliber heavy machine gun, and a Mk19 40mm automatic grenade launcher. It carries four crew radios as well as the AN/VIC-2 intercom system. It is capable of carrying 25 combat equipped Marines in addition to the crew of 4: driver, crew chief/vehicle commander, gunner, and rear crewman.

• AAVC-7A1 (Command): This vehicle does not have a turret, and much of the cargo space of the vehicle is occupied by communications equipment. This version only has two crew radios, and in addition to the VIC-2, it also carries two VRC-92s, a VRC-89, a PRC-103 UHF radio, a MRC-83 HF radio and the MSQ internetworking system used to control the various radios. This AAV has a crew of 3, and additionally carries 5 radio operators, three staff members, and two commanding officers. Recently, the C7 has been upgraded to use Harris Falcon II class radios, specifically the PRC-117 for VHF/UHF/SATCOM, and the PRC-150 for HF.

• AAVR-7A1 (Recovery): This vehicle also does not have a turret. The R7 is considered the "wrecker", as it has a crane as well as most tools and equipment needed for field repairs. It is by far the heaviest of the three, and sits considerably lower in the water. Crew of three, not including the repairmen.

Many P7s have been modified to carry the Mk 154 MCLC, or Mine Clearance Line Charge. The MCLC kit can fire three linear demolition charges to breach a lane through a minefield. MCLCs were used in the 1991 Persian Gulf War and again in Operation Iraqi Freedom in 2003.

In the 1970s, the US Army used an LVTP-7 as the basis for their Mobile Test Unit (MTU), a ground-based antiaircraft high energy laser. After several successful test firings at Redstone Army Arsenal, the laser was reportedly transferred to NASA.
