Airbag heads: conical parts connecting the body and the mouths of the air bag.
Airbag mouths: either metal valves mounted on both ends of the air bag for inflating with air or a valve on one end and a metal lug on the other end used to haul the air.

Advantages

Higher strength materials have been used in air bag production, allowing them to have much more bearing capacity.
Airbag launching method has the advantages of requiring less permanent infrastructure, risk, and cost. The airbags provide support to the hull of the ship, air bags rolling motion take a vessel launch into water, thus it is arguably safer than other options like sideways launching.
Besides, marine airbag need no extra maintenance and after use they can be cleaned and folded in the corner to wait for another mission.
Unlike most other launching methods that are fixed infrastructures, airbag launching has relatively less limitations and can be used in versatile ways. It overcomes the disadvantage of fixed track launching in which capacity of shipbuilding and ship repairing is limited by the fixed infrastructures especially in small and medium-sized shipyards.
