noun
landing ship
Military term for a vessel designed to transport and land troops, vehicles, or supplies directly onto a shore.
揚陸艦艇が海岸に部隊を揚陸させた。

揚陸艦 is a broader term for any landing ship, while 揚陸艦艇 specifically refers to smaller landing craft or boats.
Compound of 揚陸 (landing, unloading) and 艦艇 (naval vessels). The exact historical derivation is uncertain; the term is a modern military coinage.
