The Record
American Allen M. Sumner-class destroyer, screening HMAS Melbourne during overnight exercises in the South China Sea. At 03:15 on 3 June 1969 her watch officers turned the wrong way in response to a course-change signal and put her directly into the Melbourne's bow. Cut cleanly in half; the forward section sank in three minutes with most of the sleeping crew aboard. 74 dead, including three brothers from Niobrara, Nebraska. The Melbourne's commanding officer was exonerated at the joint inquiry; the destroyer's two duty officers were court-martialled.
The Vessel
USS Frank E. Evans (DD-754) was an Allen M. Sumner-class destroyer of the United States Navy, commissioned at the Bethlehem Shipbuilding yard at Staten Island on 2 April 1945. She was 114 metres long, 3,460 tons full load, armed with six 5-inch guns in three twin turrets, twin 40mm Bofors mounts, and ten 21-inch torpedo tubes. Her designed speed was 34 knots on twin-shaft General Electric geared turbines.
The Allen M. Sumner class had been the principal American destroyer design of the later Pacific War. 58 ships of the class were commissioned between 1944 and 1945; USS Frank E. Evans was the 43rd of the class. Her post-war service included extensive Pacific deployments, participation in the Korean War, and multiple deployments to the waters of Southeast Asia through the 1950s and 1960s. She was, by 1969, a 24-year-old destroyer of a class that had been overtaken by newer American destroyer types.
Her commanding officer in June 1969 was Commander Albert S. McLemore, 42 years old, a career U.S. Navy officer on his first destroyer command. Her crew was 273 officers and ratings.
The Voyage
On the evening of 2 June 1969 USS Frank E. Evans was operating with the Australian aircraft carrier HMAS Melbourne in the South China Sea, approximately 200 nautical miles southwest of Luzon, Philippines. The exercise was SEATO Sea Spirit, a multinational anti-submarine warfare training operation combining U.S. Navy, Royal Australian Navy, Royal New Zealand Navy, and Royal Navy ships. Melbourne was the exercise's principal carrier; Frank E. Evans was assigned plane-guard duty for Melbourne's aircraft operations.
The tactical situation was almost identical to that of the 10 February 1964 HMAS Voyager collision, five years and four months earlier. The same carrier (HMAS Melbourne) was conducting the same plane-guard operations with a different destroyer. The Royal Australian Navy had, by 1969, implemented multiple procedural changes to prevent the recurrence of the 1964 collision: specific radio communications protocols had been established; plane-guard positioning had been made more rigid; and Melbourne's bridge team had been explicitly briefed on the 1964 Voyager incident. Despite these reforms, the circumstances that had produced the 1964 collision reoccurred on the night of 2-3 June 1969.
Melbourne signalled her turn to starboard at approximately 03:14 on 3 June 1969 to begin an air-strike launch operation. Frank E. Evans was on Melbourne's starboard quarter in plane-guard position. Commander McLemore was asleep in his sea cabin; the bridge watch was being conducted by Lieutenant Ronald Ramsey (the officer of the deck) and Lieutenant-junior grade James Hopson (the junior officer of the watch). Ramsey and Hopson misinterpreted Melbourne's turn signal as indicating a different manoeuvre from the one actually being executed.
The Disaster
Ramsey ordered Frank E. Evans to turn to starboard in response to what he believed was the appropriate plane-guard repositioning manoeuvre. The turn placed Frank E. Evans directly across Melbourne's course. Hopson, the junior officer of the watch, did not challenge the manoeuvre. Melbourne's bridge team observed Frank E. Evans's turn at approximately 03:14:30 on 3 June 1969. Melbourne ordered hard reverse and slammed her engines to full stop. The manoeuvre came too late.
Melbourne's stem struck Frank E. Evans's port side at Frame 49 at 03:15 on 3 June 1969. The collision broke Frank E. Evans in half at Frame 48. Her forward section, containing the bridge, the forward 5-inch gun mount, and approximately one-third of her crew, capsized to starboard and sank in approximately three minutes.
74 of USS Frank E. Evans's crew died, virtually all of them in the forward section of the ship that was cut off by the collision. Commander McLemore, asleep in his sea cabin forward of the bridge, was killed. The three Sage brothers of Niobrara, Nebraska (Gary, Gregory, and Kelly) were all aboard USS Frank E. Evans and all were killed in the forward section.
The Legacy
The collision on 3 June 1969, reproducing the pattern of the 10 February 1964 Voyager collision, produced a second round of investigations into the command-and-control protocols governing carrier plane-guard operations. The Joint Board of Inquiry (involving U.S. Navy, Royal Australian Navy, and Royal New Zealand Navy officers) produced findings in December 1969 that placed primary responsibility on the bridge team of USS Frank E. Evans (specifically Lieutenants Ramsey and Hopson) for the course change that had caused the collision. Ramsey was court-martialled and dismissed from the U.S. Navy; Hopson was administratively separated. Melbourne's commanding officer Captain Stevenson was exonerated of direct responsibility.
The broader institutional consequences were more significant. The incident produced a permanent reform of multi-national exercise command-and-control protocols that had not been adequately addressed after the 1964 Voyager incident. The U.S. Navy, Royal Navy, and Royal Australian Navy jointly established revised plane-guard operations specifications in 1970 that substantially reduced the risk of collision between destroyer escorts and aircraft carriers during flight operations. The revised specifications remain the basis for modern multi-national carrier operations.
The three Sage brothers of Niobrara (Gary, 22; Gregory, 21; Kelly, 19) were all seamen and had been permitted to serve together aboard USS Frank E. Evans under a specific request they had made to the U.S. Navy in 1967. Their deaths produced a specific American public reaction that paralleled the 1942 Sullivan brothers case. The Sage family's consent to their three sons' joint service had been granted under the understanding that the U.S. Navy's Sole Survivor Policy (established in 1948 after the Sullivan brothers) would not apply because no previous Sage brother had died in combat; the 1969 Frank E. Evans incident established, retrospectively, that the Sole Survivor Policy did not apply to multi-brother non-combat deaths. The Sage family's subsequent campaign for recognition contributed to the American commemoration of the Sage brothers at the USS Frank E. Evans Memorial at the USS Harder Memorial Park in Niobrara, Nebraska.
The wreck of USS Frank E. Evans's forward section lies at approximately 3,000 metres depth in the South China Sea. Her after section (which was preserved after the collision and was towed to Subic Bay, Philippines, for examination) was eventually sunk as a target in 1970; her wreck position is approximately 100 nautical miles northwest of the forward section.
The 74 dead of USS Frank E. Evans include a specific group who have been the subject of a continuing American political campaign: the 74 dead were killed in the waters of the South China Sea, which in 1969 was formally considered by the U.S. Department of Defense as outside the Vietnam War combat zone. The dead of USS Frank E. Evans have therefore not been listed on the Vietnam Veterans Memorial in Washington D.C. The continuing campaign to include their names on the Vietnam Veterans Memorial has been led by the families of the 74 dead, by the surviving crew members, and by a bipartisan group of American members of Congress. As of 2025 the names have not been added to the Memorial; the decision rests with the U.S. Department of the Interior. The 3 June 1969 Frank E. Evans collision remains the largest single U.S. Navy peacetime casualty event of the Cold War.
