 Upgrades to the AAV will be added to around 392 vehicles (carrying one Marine brigade) out of the fleet of 1,062, including "limited survivability upgrades" of blast-resistant seats, additional armor, and a new transmission.Having AAVs self-deploy directly from ships is quicker than loading vehicles onto a connector, but long-range anti-ship missiles will force future amphibious invasion forces to stay between from shore.A high-speed connector can make that trip in 1–3 hours, while an AAV on water would take 15 hours to travel that distance.
