0The 2nd seems much more frequent:02br 0049 on "working in a submarine"02br 05002br 02br 00 working aboard a submarine02br 0510240hrefhttp://books.google.com/books?q=%22working+in+a+submarine%22&btnG=Search+Books241hrefhttp://books.google.com/books?q=%22aboard+a+submarine%22+%0D%0A%22working+aboard+a+submarine%22+&btnG=Search+Books
0Actually, I'd say "My brother is in the Navy, assigned to a submarine."02br 02br 00If he's just "working" there it doesn't sound like he's part of the crew. 02br 02br 00However, if you want to work on the "onboard" thing, then say something like "The last time they were in home port, I was able to visit him onboard." (or on-board - both are acceptable.)
