Over the past 15 years the Chinese have introduced a steady stream of new amphibious armor, each with evolutionary improvements. In a classic "Tortoise vs Hare" race, the slow steady Chinese development has outpaced the US, leaving the USMC in the 1972-vintage AAV-7A1 amphibians for the foreseeable future. Like the Comanche and Crusader before it, the cancellation of the EFV, in development since the 1970s at a program cost of over $3 billion, marks another failure of US "leap ahead" acquisition strategy.
Truth hurts ... and it was utterly obvious in the 90's that AAAV/EFV was a crappy idea.
