What are the requirements for the hull steel plate for the deck of aircraft carrier

The requirements of hull steel plate for the deck of aircraft carrier are relatively low, which are basically pressure plates for submarine. The yield strength is usually 450 MPa and 550 MPa, and the thickness is 22-28 mm.

In order to prevent torpedo and submarine missile bombardment, the underwater part of the hull is made of steel plate with a thickness of 150-203 mm. There are also double or triple hulls. When the outer hull steel plate is punctured, there is a protective layer, which enhances the anti Strike ability of the aircraft carrier. In the past, aircraft carriers used to add armor plates to vulnerable parts to resist all kinds of unexpected attacks.
