Template:Fleet-boat-propulsion-HOR-4-AC

This template is used to ease editing and provide consistent formatting to the propulsion section of the infobox of United States Navy fleet submarines (Gato, Balao, and Tench classes). These submarines had the same general propulsion plant, with a few differences in manufacturers and numbers.

This particular template is for use on boats with Hooven-Owens-Rentschler engines and four high-speed Allis-Chalmers electric motors. Here is a full list of all fleet boat propulsion templates available:
