Sealift is a military logistics term referring to the use of cargo ships for the deployment of military assets, such as weaponry, military personnel, and materiel supplies. It complements other means of transport, such as strategic airlifters, in order to enhance a state's ability to project power. A state's sealift capabilities may include civilian-operated ships that normally operate by contract, but which can be chartered or commandeered during times of military necessity to supplement government owned naval fleets.
