What does sealift mean?
Sealift denotes the movement of cargo by ship, usually when large quantities must be transported more economically than by aircraft or when land routes are impractical. The word commonly appears in discussions of military logistics, international commerce, disaster relief, and the movement of heavy equipment or bulk supplies. In emergency situations, sealift may be the only practical means of reaching isolated communities with food, fuel, medicine, or other necessities. The verb “to sealift” means to transport something by ship in this manner. Although the expression is chiefly North American, the underlying practice is universal: maritime freight transport has long been one of the most efficient ways to move goods over long distances. The term is more specific than general “shipping” because it emphasizes transport performed by sea rather than by other available methods.
The transportation of goods by ship, especially in bulk, or a service or operation for doing so.
"The port handled another sealift of grain and construction materials."
Common in military, commercial shipping, and emergency-relief contexts.
To transport goods by ship, especially in bulk.
"The navy was ordered to sealift emergency supplies to the island."
Usually transitive; the goods or materials being transported are the direct object.
Plural forms refer to separate cargo shipments or sealift operations.
"Several sealifts were delayed by storms in the Atlantic."
Before aircraft became routine cargo carriers, sealift was often the only practical way to move supplies across oceans.

Etymology of sealift
Sealift is a compound formed from “seal,” in the sense of a ship used to carry cargo, and “lift,” meaning to transport or raise. The compound developed during the era when maritime cargo transport was routinely described as sea or ship lifting. Its modern use became especially associated with military and relief logistics, in which large shipments were moved across oceans by vessel.
How sealift is actually used
The term is especially common in North America in military, commercial, and emergency-relief contexts. In the verb form, it normally takes a direct object, such as “to sealift supplies.” It is distinct from the general term “sea lift,” which can refer more broadly to lifting something from the sea.
