The '''''Lewis and Clark'' class''' of dry cargo ship is a class of 14 [[underway replenishment]] vessels operated by the [[United States Navy]]'s [[Military Sealift Command]]. The ships in the class are named after famous American explorers and pioneers.

==Development==

''Lewis and Clark''-class ships replaced the existing eighteen [[Mars-class combat stores ship|''Mars''-]] and [[Ness-class combat stores ship|''Sirius''-]]class combat store ships and the {{sclass|Kilauea|ammunition ship|1}}s. When operating in concert with a {{sclass|Henry J.

The first of the fourteen ships, {{USNS|Lewis and Clark|T-AKE-1}}, was placed in service with the [[Military Sealift Command]] (MSC) in June 2006. The ships were built to commercial rather than military standards. This was done to minimize costs and to demonstrate the ability to competitively build ships on the civilian market.<ref>{{cite news | url= http://www.defenseindustrydaily.com/us-navy-on-the-take-as-it-beefs-up-supply-ship-capacity-updated-01826/

They are provided with passive defenses against mines and torpedoes, and atomic, biological, and chemical (ABC) weapon countermeasures. However, they are designed with appropriate space and weight reservations "to allow future installations of self-defense systems as required."}}</ref> The ships in the class are named after famous American explorers and pioneers.
NASSCO was awarded a detailed design and construction contract in October 2001. The fourteenth ship of the class was delivered on 24 October 2012. As the class entered serial production, NASSCO has increased learning and production efficiencies to make substantial reductions in labor hours, from hull to hull. For example, T-AKE-7 was produced with fewer than 50&nbsp;percent of the worker-hours it took to produce T-AKE-1, and had a 37&nbsp;percent reduction in total construction time.

==Mission==
As part of [[Military Sealift Command]]’s (MSC) [[Naval Fleet Auxiliary Force]] (NFAF), the ship's mission is to deliver ammunition, provisions, stores, spare parts, potable water and petroleum products to carrier battle groups and other naval forces, serving as a shuttle ship or station ship. T-AKE-1 and -2 were assigned to one of the two active Maritime Prepositioning Ship squadrons, which are permanently forward deployed to the Western Pacific Ocean and Indian Ocean. While identical in configuration to T-AKE-3 to -14, their mission is to provide selective offload of cargo for resupply and sustainment of U.S. Marine Corps forces ashore.<ref>{{cite news | url= http://www.naval-technology.com/projects/lewisandclarke/

In their primary mission role, the T-AKEs provide logistic lift to deliver cargo (ammunition, food, limited quantities of fuel, repair parts and ship store items) to U.S. and allied ships at sea. In their secondary mission, the T-AKEs may be required to operate in concert with a ''Henry J. Kaiser''-class (T-AO 187) fleet replenishment oiler as a substitute station ship to provide direct logistics support to the ships within a carrier strike group.

== History ==
On 8 February 2008, dry cargo/ammunition ship USNS ''Lewis and Clark'', the first ship in Military Sealift Command's newest class of ships, returned to Naval Station Norfolk, Virginia, after its first deployment.

The ship successfully completed a six-month tour to the U.S. Central Command area of operations to resupply U.S. Navy ships, providing logistics support in the Persian Gulf, around the Horn of Africa, along the length of Somalia and beyond the equator.<ref>{{cite news | url= http://www.msc.navy.mil/sealift/2008/March/lewisandclark.htm
