Yet the overwhelming impetus driving the development of the EFV is operational maneuver from the sea [OMFTS]. The vision behind the EFV is one in which a group of vehicles move from apmphibious shipping twenty-five nautical miles from the shoreline and then travel at a high speed to a littoral penetration point to come ashore and seamlessly complete some tactical mission.
The layout and construction of the EFV have been optimised for that high speed movement over water. but this is not a reasonable focus. The mission profile guidance originally given to the EFV (then the AAAV) team was for a 20% operational time in the water and 80% on land. Since then, the mean operational time in the water for all envisioned EFV missions has been revised to 8.2%[!]. Thus the Marine Corps predicts the EFV to operate eight out of every one hundred hours of vehicle operation in water.
If the Marine Corps had fielded the EFV in January of 2001, the high water speed capability would not have been used in either Operation Enduring Freedom or Operation IIraqi Freedom both expeditionary operations by any standard. (p.9-10)
