At random: The United States submarine USS TRITON was fitted with twin reactors and was considered the longest submarine ever built until the advent of the OHIO class. The TRITON was designed for a surface displacement of 5,900 tons. Large submarines of other countries have been the Japanese I-400 (5,220 tons), and the French SURCOUF (2,880 tons).

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...
