USNS Choctaw County (JHSV-2/T-EPF-2), (ex-Vigilant) is the second Spearhead-class expeditionary fast transport,[1] which is operated by the United States Navy's Military Sealift Command and was built in Mobile, Alabama.

[3] It has a flight deck for helicopter operations and a loading ramp that allows vehicles to quickly drive on and off the ship.

The ramp is suitable for the types of austere piers and quay walls common in developing countries.

[3] On 6 October 2011, Secretary of the Navy Ray Mabus announced in Ackerman, Mississippi that the second Expeditionary Fast Transport, previously having been named Vigilant by the United States Army before the transfer of the EPF program to the Navy,[1] would be named USNS Choctaw County.

[5] Since the ship will be operated by the Military Sealift Command and not the United States Navy itself, it will carry the USNS designation and not USS.
