The Polaris type model is 48" long, with a 41/2" beam and weighs 211/2 lbs. it displaces 662 cu. in and was designed to have three independent and sealed compartments. The fore section contains the single‑channel tube Kraft receiver and the homemade stepper switch mechanism; the midsection is for flooding the ER‑42 lead‑acid batteries are located there; and the aft section houses the drive motor, steering and pumping systems.
The installation details shown should be considered a guide to assist the reader with the development of his own system, based upon equipment available to him.
Although this project obviously is for the more advanced hobbyist, it is not as difficult as it appears for anyone with a background of radio control experience. The hull itself is more tedious than difficult. The installation pictures, which do afford an idea of such basic components as drive, steering, pump, and pump valve motors‑which are required regardless of the system employed to control them also portray the designer's economical single‑channel receiver system, utilizing carefully shopped for surplus items, and a necessarily more complex hookup to obtain many control functions from a rudimentary radio. A multi-channel radio with servos is simpler,
The design chosen for this project is the fleet ballistic missile type of the first generation. There are five commissioned from the George Washington SSBN 598 to Abraham Lincoln SSBN 602. this class was the first to fire the Polaris intermediate range missile either submerged or surfaced. The decals 594 stand corrected since this number is given to a sub in the attack class, the basic difference between the two being the design of the superstructure to accommodate the ballistic missile tubes\
