SSBN. ETV. Will not respond to questions about sensitive or classified subjects. My views are my own and I do not represent anyone.

Hi there!

Edit: since this has been asked several times:

SSBN stands for “submersible ship, ballistic missile, nuclear powered”. That is, the same overall type of ship as the Red October.

ETV stands for “Electronics Technican, Navigation”, because N was already taken by Nuclear Electronics Technicians. I work with everything from interior communications and announcing circuits to Electronics, shipwide atmospheric monitoring, navigational inertial gyroscopes, strategic nuclear missile navigation, and tank level indicators to basic underwater submarine navigation using the voyage management system and even helming the ship itself.

    1. Unless there’s a swim call for some reason (which never happens on an SSBN), no.

    2. Nope. Unless there’s some emergency, or we’re replenishing food or repair parts.

    3. Alarms:

    • General Alarm - some kind of general emergency like fire or security violation
    • Diving Alarm - diving and surfacing
    • Collision Alarm - collision or danger of collision, flooding
    • Power Plant Causality - engine room emergency like radioactive material spill or steam line rupture
    • Missile Jettison Alarm - something is terribly wrong with a missile and we need to jettison it.

    1. Yes but only when we’re surfaced, for obvious reasons.

    2. No, it’s not required, but I learned anyways in my own free time!
