Sealift is a term used predominantly in military logistics and refers to the use of cargo ships for the deployment of military assets, such as weaponry, vehicles, military personnel, and supplies. It complements other means of transport, such as strategic airlifts, in order to enhance a state's ability to project power.
Sealift shipping falls into three broad categories: dry cargo freighters, liquid tankers, and passenger or troop ships. During joint operations, dry cargo ships may transport equipment and supplies required to conduct and sustain the operation; tankers carry fuel; while passenger and troop ships carry personnel to the theater and allow the evacuation of noncombatants or those in need of medical aid.
