up with a launch on 16 August. With DASO complete, Pulaski returned to the fleet, beginning her next operational patrol on 28 October 1971. During her sixth operational test, Pulaski's Gold Crew launched four Poseidon missiles on 2 March 1973. In July 1974, SubRon 14 bestowed Pulaski with the Battle Efficiency (Battle "E") Award, the first ever for any ballistic missile boat. Later that year, she completed her 50th strategic deterrent patrol. Late in 1980, Pulaski entered Newport News Shipyard for refueling and overhaul where she was modified for the UGM-96 Trident I ballistic missile. Reassigned to Submarine Squadron (Subron) 16, following overhaul and refueling, she proceeded to her new homeport at Naval Submarine Base, Kings Bay, GA, arriving on 10 December 1982. During the post-overhaul DASO, on 19 April 1983, the Gold Crew successfully launched a Trident I ballistic missile and had a Trident missile flight terminated on a malfunction after launch. Returning to fleet operations, SSBN-633 began her next deterrent patrol on 3 June. On 17 June 1985, Casimir Pulaski successfully test fired four Trident I missiles in the Atlantic Test Range Range off Cape Canaveral, Florida. In October 1985, Casimir Pulaski Gold Crew won the Arleigh Burke Fleet trophy for most improvement in combat efficiency of any Navy unit in the US Atlantic Fleet during Fiscal Year 1985, under the Command of Commander Conrad A. Plyler, Jr, USN. The ship went on to win the fiscal year 1986 Battle Efficiency "E" for Submarine Squadron Sixteen and the Fleet Ballistic Submarine Superior Performance Award Trophy (Providence Plantation Trophy) for the US Atlantic Fleet under the command of Commander Plyler (Gold Crew) and Commander William W. Schmidt (Blue Crew). The ship also received the Navy Unit Meritorious Commendation ribbon for her service from 1 January 1985 to 2 October 1986. During this period, the ship participated in a successful Atlantic Fleet Follow-on Operational Test on the Atlantic Test Range, evaluating the readiness of the Trident C-4 missile. From 1 April to 20 May 1989, Casimir Pulaski participated in Concept of Operation Exercise LANTCOOPEX 1-89, held at a remote site—Port Canaveral—away from an SSBN refit port, arriving there after the end of Gold Crew deterrent patrol. After being relieved by the Blue Crew, both crews—with tender personnel—conducted a complete resupply of the ship and performed major maintenance and repairs and a torpedo reload with no submarine tender present, just a
