The large stack contained a small diesel exhaust funnel and a small 620 shp gas turbine engine that provided "quiet" power for speeds up to 6.5 knots during experiments in which the main propulsion diesel would be too noisy. A bow propeller pod could propel the ship at up to 4.5 knots in addition to providing precise maneuvering. In September 1969 three 208-ft oceanographic hulls, AGOR 4-5 and AGS 31, were selected by the Oceanographer of the Navy for deactivation and layup by MA as part of an AGOR cutback program. AGOR 5 was loaned to New Zealand on 10 Aug 1970 and AGOR 4 was transferred on 22 Nov 1970 to the University of Miami for further operation from Port Everglades, Fla.
