At random: Traditionally, United States submarines have been named after fish and other marine creatures. One exception was the Navy's first submarine HOLLAND which was named after its inventor, John Philip Holland. Today, ballistic missile submarines are named for famous American patriots, with the newest class, the OHIO class, named after states. The LOS ANGELES class of attack submarines are named for United States cities. The nations news class of submarine, the Virginia class, is also named for US States, making them the capital ships of the navy.

Subject: mechanical diving alarm

I'm looking for information on the older mechanical diving alarm. This one was used on the Permit era boats in the 60's and 70's. I would like to find the electrical diagram/specs for the actuator windings, or the manufacturer.

Stamped into the metal is an F within a circle with what appears to be a lightening bolt.

Joe, these "older" diving alarms (a.k.a. klaxons) used a motor actuated diaphram (via a cog) for the vibration (sound) produced. They are/were made "mostly" by Federal Signals (probably same as your logo)... They were still making them several years back for a price tag around $1,300.00 - Hope this helps answer you question...
