The ZBD series of armored amphibious vehicles are not as formidable as the EFV, but are more recent, although smaller, vehicles than the AAV7 the U.S. marines are currently equipped with. The Chinese continue to build ZBD type vehicles, and practice with them. ZBDs are typically launched from ships up to ten kilometers offshore, and can get to a beach in less than 15 minutes.
The EFV was previously called the AAAV (Advanced Amphibious Assault Vehicle). Weighing nearly 36 tons, the EFV is 3.4 meters (10.5 feet) tall, 3.9 meters (12 feet) wide and just under 10 meters (30 feet) long. It's armed with a 30mm automatic cannon (MK34 Bushmaster) and a 7.62 mm co-axial machine gun. The EFV also has better armor protection and electronics than the AAV7 it replaces. The EFV is about 25 percent heavier than the AAV7, and somewhat larger. The U.S. had planned to buy 563 EFVs to replace about a thousand AAV7s. The latter will probably be retired in a decade or so.
