I’m sure someone with more expertise will chime in shortly, but I would advise against wishing for MH-53s. The aircraft are old and broken and the Navy isn’t planning on buying new replacements, and the mine clearance mission is (supposedly) being given to other platforms.
If you have your heart set on flying Navy helos, research the HSM (Helicopter Maritime Strike) community and the MH-60R. If it’s CH-53s that appeal to you, join the Marines and you may eventually have the chance to fly brand new CH-53Ks.
Edit: I thought I’d seen the most recent community sundown date in another thread, and I found it. Looks like the current plan is to get rid of them by 2025. Of course that’s (like everything else in the Navy) subject to change, but being that you’re 16, you wouldn’t even be out of flight school in time.
