An experimental evaluation was conducted to investigate the surface towing characteristics of the SSBN-623 and SSBN-636 submarines. A 1/19.394-scale model was towed in the David Taylor Model Basin deep water towing basin, varying towpoint location, metacentric height (GM), trim and several stern appendage modifications. SSBN-623 was towed in a stable configuration at speeds up to 10 kn full-scale with the sternplanes set to 25 deg trailing edge up, at trim between 4.5 ft (1.37 m) and 6.0 ft (1.83 m) down by the stern, with a GM between 0.97 ft (0.296 m) and 1.90 ft (0.579 m), and with a lower-rudder plate appendage attached. A stable towing configuration can be obtained for SSBN-636 by replacing the missing 4-ft (1.22 m) section of the lower rudder and making the same changes as listed for SSBN-623. The use of sternplane scoops stabilized both SSBN-623 and SSBN-636, but with a non-acceptable increase in towline tension.
