That makes sense. I don't know if CUS is going to change their name, but undersea surveillance...? Yes, Ocean Surveillance makes more sense as it's air, surface, and subsurface and the average Joe might not necessarily equate air with undersea.
I'd hate to hear people say "osif" (OSF)...doesn't really roll off the tongue.
How about Pacific Ocean Surveillance Center...or just POS? nah...I don't think that would fly...
