Do you have to know how to dive to be in the U.S. Navy?

Question

And also for the SWCC's?

Answer 1

You do not need to know how to swim to just be a sailor in the USN, they will teach you how to float in boot. However, you need to be a strong swimmer if you want to join any NSW (Naval Special Warfare Command) units like SEAL or SWCC.

Most of the Swicks are not required to dive. Only SEAL, EOD, ND (Navy Diver), and some other people that fix the haul of the ships will required to be at least a Basic Diver.  

Answer 2

no

Answer 3

Only if you want to be a diver.

Answer 4

No, in fact we have people who don't even know how to swim.

If you want to go SWCC you'll need to know how to swim, but not necessarily know how to dive.
