What is a common characteristic of all Wasp-class ships?

Wasp-class ships are designed primarily as amphibious assault ships, which means their main function is to support amphibious operations. This includes the capability to embark, transport, and land Marine Corps forces along with their equipment and supplies. The key features of Wasp-class ships include a flight deck for helicopters and VSTOL (Vertical/Short Takeoff and Landing) aircraft, as well as well deck facilities to launch and recover landing craft.

This design allows these ships to serve as a base for conducting various types of operations, including troop deployments, humanitarian assistance, and disaster relief, perfectly aligning with the purpose of supporting amphibious operations. While they do have some capabilities that might make them appear similar to aircraft carriers, their primary role is distinctively focused on enabling and facilitating land operations from the sea. Thus, the emphasis on their amphibious capabilities is what makes this choice the defining characteristic of Wasp-class ships.
