The ABC’s of Submarines – The Acronym Guide

Listening to your spouse speak to a fellow sailor can sound like a jumbled version of the ABCs and includes words that are a far cry from a description of what they mean. Here is a list of terms and acronyms that will help you decide more of the conversation or at least assist with decreasing the number of “what does that mean?” during dinner conversations. 


Submarines

  • BN/Boomer/ SSBN. A Boomer or “Ship Submersible Ballistic Nuclear.” These submarines are larger, contain ballistic missiles and deploy for three months. Boomers are only stationed in Kings Bay, GA and Naval Base Kitsap in Bangor, WA, and operate with two crews.
