2. Section 1- Executive Summary
Starting from 1971, the Turkish Navy acquired a total of ten U.S.-built FRAM I Gearing class destroyers
from the United States, namely Adatepe-II (D 353) (1971), Kocatepe-II (D 354) (1971), Tınaztepe-II (D
355) (1972). When the Cyprus operations begun at 20th of July 1974, Kocatepe destroyer was ready at
the Mersin Harbour.
KOCATEPE DESTROYER SHIP WRECK (D 354)
sinking of the ship:
When the Cyprus operations begun at 20th of July 1974, Kocatepe destroyer was ready at the
Mersin Harbor. It was heard that the Greek Ships would change their flags with Turkish flags and
use radio operators who knew Turkish. That era's head minister Ecevit was interviewed with the
American authorities but couldn't accomplish anything. While the operations going on, Turks got
an intelligence that was saying that there was a Greek fleet around Paphos at 21st of July 1974.
Because of this S-2E class Tracker Sea Sentry planes belonging to the 301 fleet were sent to
area for sentry. The radar was showing 4 destroyers and 7 cargo ships headed to the island. For
confirmation, RF-84F planes belonging to the 184th fleet were sent to area. But no physical
contact made. Kocatepe and two other destroyers were sent to area for investigation. There was
little or no armed contest at the beachhead on 21 July 1974, and during this time, the second
wave of Turkish forces departed from Mersin port.
Following the dispatch of the L176 Lesvos landing craft vessel to Paphos by the Hellenic Navy,
the Turkish Air Force received reports of a Greek task force of ships off the coast of Paphos and
assembled a force of around 28 strike aircraft from two squadrons to attack the force with 750lb
bombs and guns. This however, was a signals deception performed by the Greek Cypriot Naval
Command, which transmitted false radio signals indicating that three Turkish destroyers (looking
for the Lesvos) off Paphos, were in fact Greek ships. They were actually the Turkish Navy
vessels D-354 Kocatepe, D-353 Adatepe and D-355 Tinaztepe. All three vessels were struck by
friendly fire, and in turn put up 20mm and 40mm anti-aircraft fire, reportedly downing three
aircraft. The D-354 Kocatepe sustained a fatal hit and sank with the loss of 54 crew. ["Cyprus,
1974", by T. Cooper and N. Tselepidis, published October 28, 2003 for ACIG.org. ]
Having intercepted intelligence that Greek Cypriot Commander of the Navy, Lt. Col Papayiannis
is heading to Karavas to assess the size and dimensions of the Turkish landing force, a team of
12 Turkish parachutists are dropped on the Mirtou-Asomatou road in order to ambush his convoy.
The Turkish troops manage to wound Papayiannis before they are wiped out by his personal
guard force, forcing the Greek Cypriot plan to be abandoned.
At the morning of 21st July everyone was waiting information. Because Greek support could reach the island. Also none of planes made contact;
the Anamur radar was showing the ships. Turkish operation center was determined to block the fleet. At 1:00 pm an attack was planned on this fleet. At 2:00 pm F-
100D planes from 111th fleet and F-104 planes from 141th fleet got on their way. For stopping a possible Greek landing, all the ships around the area would be
bombed. The report that came shocked everyone, who was waiting good news that would say Greek ships found and sunken. Because in the area that Turkiye
didn't supposed to have any ships, Turkiye confirmed not to have any ship, Turkiye had 3 destroyers. Which one of them was Kocatepe and which sunken by
Turkish planes at 22nd of July 1974. The others Adatepe and Maresal Cakmak had reached to Mersin with survivors and wounded. With this tragic accident
Turkiye lost 54 good marines. The best reasons of this accident were the need to stop any Greek landing, tension of this possible landing, and the intelligence
about the Greek ships with Turkish flags. After this, the possible leaks, needs and musts had been completed in the Turkish army. Also gossips were saying that
there could be an interference with the radar systems of the Turkish navy. It is thought that the ship was sunken near Akrotiri. Before the ship sunken, the crew
abandoned the ship with the order of the Captain Colonel Guven Erkaya. The survivors had been rescued by different navies. A group including captain had been
rescued by Israel navy, a group had been rescued by English and some rescued by Turkish navy. Captain Ian Mckechnie (unpublicized for political
reasons, was his ship-to-ship transfer by helicopter of 72 survivors from a Turkish destroyer, sunk
by friendly fire during the Cyprus war in 1974. He was later awarded the Turkish Distinguished

3. Service Medal, the only foreign recipient in the history of Ataturk's republic, and allowed to wear it
by the Queen. The captain of the Kocatepe destroyer had become the head of the Turkish Navy on the following years.

Sunday July 21, 1974
14:30 Cyprus The Naval Commander of Cyprus is moving along the road between Mirtou and Asomatou,
on his way to Karavas so as to determine the state of the Turkish forces on the beachhead and possible
Hellenic measures. A force of about 10-12 Turkish paratroopers is dropped from a transport aircraft, and
manage to injure the Commander prior to their destruction. His mission is postponed.
Cyprus ELDYK, now reinforced with the additional 450 troops that disembarked the "Lesbos", manages to obliterate an entire Turkish regiment at Kioneli. The GEEF once again
orders the unit to withdraw, in order perhaps to make sufficient forces available for the defense of the airport.
Hellas The landing ship "Rethimno" heads to Cyprus carrying the 573 TP and 550 Cypriot volunteers.
Cyprus The Commander of the Naval Station in Pafos informs the GEEF that 3 ships (the destroyers Turkey had sent in search of the "Lesbos") have been detected. The GEEF
responds that this is a Hellenic task force, knowing that its communications were monitored. The Turkish Air Force Command sends 7 aircraft to sink the ships, without first
verifying the presence of Turkish vessels in the area.

11. 14:35 Cyprus The Turkish aircraft spot the 3 destroyers 10 nm west of Pafos and begin their attack. The visible Turkish flags are ignored as a Hellenic attempt at confusion. 2 or
3 aircraft are shot down by the defending Turkish ships.
14:45 Cyprus The Turkish Navy destroyer "Kocatepe" is sunk, while the other two suffer significant
damage that renders them non-battle worthy. The ships head towards Mersina having suffered more than
232 dead from the sunken ship alone. Turkey claimed this event as a resounding victory against the
Hellenic Navy up until July 25 - the date they announced the loss of the "Kocatepe".

12. The survivors of the Turkish destroyer Kocatepe which was sunk during the conflict were treated at TPMH RAF
Akrotiri Cyprus - The Princess Mary's Hospital until repatriated to Turkey by the Turkish Red Cross.

13. RESEARCH FOR THE LOST VESSEL IS UNDER WAY SINCE MANY YEARS.
ACCESS TO DETAILED INFORMATION IS DIFFICULT DUE TO THE PRESENT POLITICAL SITUATION IN CYPRUS.
3RD PARTIES (BRITISH, US-AMERICAN, ISRAELI) INVOLVED DURING THE 1974 CONFLICT AND THE DESTROYER
INCIDENT ARE NOT OF GREAT HELP.
ISRAELI SOURCES, PARTLY INVOLVED IN THE RESCUE OPERATIONS FOR THE KOCATEPE SURVIVORS, "RECOMMENDED"
STOPPING ANY FURTHER INVESTIGATIONS AND NOT GETTING INVOLVED IN THE MATTER.
BRITISH NAVAL AND OTHER MARINE SOURCES GAVE WRITTEN STATEMENTS NOT TO KNOW OF THE LOCATION OF THE
WRECK, BUT LLOYDS OF LONDON HAS A SINKING POSITION OF THE KOCATEPE.

16. SHIPS HISTORY
The USS HARWOOD (DD861), a Gearing class destroyer, was the last combatant vessel built by the
Bethlehem Steel Corporation at their San Pedro, California, shipyard. The ship is named for Commander
Bruce Lawrence Harwood, an heroic aviator, who was killed while leading a fire fighting party aboard the
USS PRINCETON (CVL 23) when that vessel was under attack by enemy Japanese aircraft in the vicinity
of the Philippine Islands, during the Second Battle of the Philippine Sea on 24 October 1944. CDR
Harwood was awarded the Navy Cross and Purple Heart Medal posthumously. The ship’s keel was laid
on 29 October 1944, launched on 22 May and was commissioned 28 September 1945, just six weeks
after World War II ended. The first Commanding Officer was CDR Reid P. Fiala, and X.O. was LCDR A.
J. Wanamaker, Jr.
For the first three and a half years of her life, the ship operated with the Pacific Fleet and was home
ported at San Diego. HARWOOD made two Far East Cruises, during which she visited ports in China,
Japan, Korea, Shanghai, Hong Kong and Okinawa. Between these two cruises she underwent three
months’ overhaul at Bremerton, Washington, in late 1947. In January 1949, she entered Mare Island,
California, shipyard for an eight months’ overhaul. At this time the most modern anti-submarine
equipment then known was added to the ship, and she was redesigned an escort destroyer (DDE).
Subsequently, she was transferred to the Atlantic Fleet, arriving at her new homeport, Newport, Rhode
Island, via the Panama Canal in August 1949. For the next six months, the HARWOOD conducted short
exercise cruises in the Atlantic, visiting Key West and Bermuda. In March 1950 the ship participated in
Operation PORTREX in the Caribbean, one of the first large post-World War II anti-submarine hunter-
killer operations. After another period of local operations, the ship became part of the Operation
Development Force. While developing cold weather operational methods, she visited Argentia,
Newfoundland, and Reykjavik, Iceland, and steamed north of the Arctic Circle giving her crew their first
experience with continuous daylight.
After an upkeep period, HARWOOD made her first Mediterranean cruise, joining Sixth Fleet in
September 1950. In the Mediterranean, she visited ports in Sicily, Malta, and on the French Riviera. In
January 1951, she provided plane guard services for the light carrier Monterey off Pensacola and was an
anti-submarine school ship in Key West. She then went into a five months’ navy yard overhaul. After a
brief period of competitive exercises, the HARWOOD proceeded to Guantanamo Bay, Cuba, for the usual
post-yard six week period of refresher training designed to test her battle readiness and the quality of her
yard work.
Following her return to Newport, she participated in a major Atlantic Fleet operation, entitled
LANTFLEX and then spent Christmas holidays in her homeport. In January 1952, the ship departed for a
three months’ Mediterranean cruise during which she visited ports in France, Italy, and North Africa. On
her return, she became a unit of the Atlantic Hunter-Killer Forces whose operations took her to the North
Atlantic, where she had a short trip in Grennock, Scotland, and to sub-Arctic waters off Norway. By
autumn, she was operating off Newport, and she spent the Christmas period in Fall River,
Massachusetts. In February 1953, the ship began her third tour of duty with the Sixth Fleet in the
Mediterranean where she participated in two months of exercises with navies of other NATO nations.
Late spring was spent in Boston Naval Shipyard, after which the HARWOOD won her third straight
Battle Efficiency Award, the Navy “E”, during refresher training at Guantanamo Bay. During the fall of
1953, she conducted destroyer exercises off Newport, again spending the winter holiday season moored
at Fall River. In spring of 1954, the HARWOOD engaged in the appropriately named Operation
SPRINGBOARD, a month long Caribbean cruise including air defense and anti-submarine exercises. On

17. this cruise, the ship visited San Juan, Puerto Rico, Saint Thomas, Virgin Islands; and Ciudad Trujillo,
Dominican Republic. After SPRINGBOARD, she conducted local hunter-killer operations and prepared
for a four and a half-month Mediterranean tour, which began in September. On this long trip, the
HARWOOD covered the entire length of the Mediterranean Sea, going as Far East as Imir, Turkey, and
Beirut, Lebanon. In January 1955, she returned to her homeport.
In spring of 1955, the ship came under operational command of the Atlantic Anti-Submarine Forces.
Employment with this command occupied the next nine months, after which the ship acted as an
engineering school for Atlantic destroyer personnel for the remainder of 1955. Following a three month
yard period in Philadelphia and the usual subsequent refresher training at Guantanamo Bay, midshipmen
from the Naval Academy and universities with Naval ROTC units embarked in the HARWOOD for two
months summer cruise in the Eastern Atlantic during which she visited Barcelona, Spain, and Dublin,
Ireland.
In the early winter of late 1956 before severe cold weather set in, and after completing an anti-submarine
patrol for Russian submarines in the North Atlantic incident to the Russian invasion of Hungary,
HARWOOD departed Newport, one in a division of three DDE’s, and, together with a submarine,
proceeded south to Havana, Cuba for a short recreational stop rudely interrupted one Sunday morning
when several busloads of Fidel Castro’s rebels attempted to shoot up then Cuban President Bautista’s
presidential palace. After a brief stop in Panama, HARWOOD transited the Panama Canal and proceeded
south to the old Spanish Main port of Cartagena, Colombia for a goodwill visit and then further south to
Salinas, Ecuador, Callao, Peru, and Valparaiso, Chile for joint anti-submarine warfare training exercises
before returning to Newport in early Spring of 1957 at the end of that three month cruise. (thanks to Philip
D. Isaac)
A visit to Bermuda preceded a Mediterranean cruise, which occupied the last five months of the year
1957.
Operations in the Atlantic and Caribbean interspersed with upkeep periods, a yard period in Boston,
and training at Guantanamo Bay, laid the groundwork for the ship’s assignment to Task Force Bravo.
The mission of this group was to develop new anti-submarine tactics to augment World War II methods.
Few people know that the Navy maintained Ready ASW groups to protect our coasts from unfriendly
submarines one of which was TF Bravo . HARWOOD operated with TF Bravo which alternated with TF
Alfa patrolling our East Coast. Click here for a great story and pictures of the USS Wasp fire Harwood
helped put out while operating with Task Group Bravo. While with Task Force Bravo, a combination
NATO exercise and Midshipmen Cruise was made in conjunction with the Canadian and British navies.
The Saint Lawrence Seaway was opened in July 1959, and the ship visited Quebec. She spent early fall
engaged in LANTFLEX 59, an all-Atlantic Fleet operation. The winter of 1959-1960 was spent in local
operations with a month at Newport for the Christmas leave period.
In March 1960, the HARWOOD again deployed to the Caribbean and in April had her first taste of
operations against a nuclear submarine, the Skipjack. After a brief NATO operation with Canadian
Forces, the ship departed from Norfolk with twenty midshipmen for the Mediterranean Midshipmen Cruise
60. During this cruise, the largest single gathering of warships since World War II occurred in Golfo de
Palma Bay in Sardinia. The ship returned to Newport in late August, then engaged in independent
steaming and destroyer exercises, closing out 1960 with a visit to Miami where the crew was able to see
the annual Orange Bowl Game. In early January 1961, she exercised with the nuclear submarine, Robert
E. Lee. After a short period in Boston, the ship escorted Polaris carrying submarines off Cape Canaveral.

18. The remainder of spring 1961 was spent preparing for entry into New York Naval Shipyard for the Fleet
Rehabilitation and Modernization program (FRAM). The FRAM program consists of virtually rebuilding a
ship from the hull up and was designed to increase the life of the many destroyers built during World War
II by six to eight years. On 2 May 1961, the HARWOOD entered the yard. The FRAM overhaul lasted
exactly nine months, during which the profile of the ship was substantially altered. Among other changes,
the bridge was totally reconstructed, new types of torpedo tubes were installed, and the anti-aircraft guns
were removed to accommodate a hanger and launching deck for the DASH, an anti-submarine
helicopter. On 1 January 1962, the homeport was changed from Newport, Rhode Island, to Mayport,
Florida. After leaving the yard on 2 February 1962, HARWOOD spent a week at Newport, where the
married members of the crew made arrangements to move their families to Mayport.
On 12 February 1962, the HARWOOD arrived at her new homeport, Mayport, Florida, and only one
week later proceeded to Guantanamo Bay for her most rigorous period of refresher training to date.
Three days in Kingston, Jamaica, provided a short break during this time. The ship returned to Mayport
on 15 April, leaving for her latest Mediterranean cruise on 22 May, stopping at Rota, Spain, for two days,
and passing through the Straits of Gibraltar. On 3 June, the HARWOOD, along with all other escort
destroyers, was redesigned a general-purpose destroyer (DD). This cruise proved to be her most
extensive to date, for it included a six week’s voyage to the Middle East. This involved two transits of the
Suez Canal and took the ship as Far East as Karachi, Pakistan, 10,000 miles from Mayport. She
returned to her homeport on 12 October.
The long awaited period of leave and upkeep was abruptly interrupted by the Cuban crisis. On only
four hours notice, the ship got underway for the Caribbean on 26 October, leaving forty-five of the crew on
shore. All of these were flown to the ship within ten days. After nearly a month of continuous steaming,
she returned to Mayport on 21 November, just in time for Thanksgiving. The ship provided plane guard
services intermittently for the Lexington for the next two weeks. The HARWOOD moored at Mayport for
upkeep and Christmas leave on 10 December.
After operations in the Caribbean for the first half of 1963, the HARWOOD left on 3 August for another
Mediterranean Cruise and visited the following ports: Golfo di Palmas and Aranci Bay, Sardinia; Palmero,
Sicily; Naples, Messina and Livorno, Italy; Golfe Juan and St. Raphael, France; Pollensa Bay, Mallorca,
and Valetta, Malta. The HARWOOD returned to Mayport, Florida on 23 December 1963.
On 1 May 1964, she left for another Midshipmen Cruise, stopping at Oslo, Norway; Antwerp, Belgium;
Southampton, England and LeHarve, France, returning to Mayport in August.
From Mayport Harwood deployed to the Mediterranean twice, participated in the Cuban quarantine
operation, and was a recovery ship for the Mercury astronaut launching in May 1963. 22 July 1966 saw
Harwood departing Mayport for her ninth Mediterranean cruise. Ports of call included Theoule-sur-Mer,
France, Naples, Italy, and Beirut, Lebanon prior to transiting the Suez Canal for operations under
COMIDEASTFOR.
After a brief visit at Jidda, Saudi Arabia, Harwood was treated to a real taste of British Hospitality as she
visited Aden, Bahrain and Mombasa, Kenya. The latter port proved to be the most interesting when the
Officers and crew where treated to a tour of the Tsavo National Game Preserve. On the way to Mombasa,
HARWOOD crossed the Equator at 45-00o
and . in true Navy tradition, 230 Pollywogs were initiated into
the Royal Order of Shellbacks.

19. Transiting the Suez Canal on 2 November 1966, Harwood rejoined the Sixth Fleet for a week of
operations before making visits to Naples and Genoa, Italy for some well earned rest and liberty. While
inport Naples, Harwood Change-of-Command Ceremonies saw Cdr. William S. Guthrie relieve Cdr. R.T.
Whitlock as commanding officer on 17 November. At this same ceremony the ship received the Desron
16 Battle Efficiency "E" won in fiscal year 1966, and the Operations "E" for departmental excellence.
A brief five day visit to the exciting city of Barcelona, Spain came in early December after which the ship
arrived in its homeport of Mayport on 17 December.
In 1966 and early 1967, she operated out ofMayport, Florida and the East Coast until sailing for her 10th
Med deployment on 29 June, 1967. Reaching Rota, Spain, on 10 July, HARWOOD joined the 6th
Fleet,
an element of stability in the ancient and volatile sea, which had so recently been churned by the Arab
war with Israel.
The HARWOOD deployed to Vietnam on 10 April of 1968. After transit of the Panama Canal and brief
but enjoyable stays in San Diego and Pearl Harbor, HARWOOD, the lone wolf of DesRon 14, began her
long journey across the Pacific to Subic Bay, R.P. There she underwent a short upkeep and preparation
before leaving for Vietnam and the gunline. Naval gunfire support off the coast of South Vietnam was her
primary duty, and one in which she was extremely successful. HARWOOD spent forty-two days on the
gunline in support of our troops ashore, destroying or damaging 410 enemy bunkers and structures,
neutralizing numerous storage and assembly areas and accounting for many confirmed enemy
causalities, firing a total of over 10,000 rounds. In this effort, the Naval Gunfire Support Officer working
for the 1st
Marine Division and directing the HARWOOD’s targeting was a former 1st
Lt on the
HARWOOD.
In addition, HARWOOD operated off the coast of North Vietnam in OPERATION SEA DRAGON, during
which time she worked with the USS BERKELEY in a massive interdiction of enemy waterborne logistics
craft described as “one if the heaviest off-shore bombardments of the war”, Fifty-eight “WBLC’s” were
either destroyed or damaged by the HARWOOD-BERKELEY team. Of these, thirty-six were officially
credited to the HARWOOD.
On five separate occasions the ship was taken under fire by enemy coastal defense batteries and in one
instance received a hit in her after gun mount, inflicting two personnel casualties and resulting in two
Purple Hearts and one Bronze Star awarded to HARWOOD crew members.
During this 1970 Med deployment, HARWOOD distinguished herself in operations with carriers, oilers and
other destroyers. She was part of the effective show of United States strength in the Eastern
Mediterranean during the September 1970, Middle East crisis. Also during this time HARWOOD
participated with other NATO forces in exercises off the coast of Greece.
The Harwood was loaned to Turkey 17 December 1971 and was decommissioned and stricken from the
rolls February 1, 1973.
On 15 February, 1973 HARWOOD was transferred to the Turkish Navy, and renamed TCS Kocatepe, D-
354. Her last Commanding Officer and Executive Officer were Captain Robert M. Marshall, USN, and
LCDR McGhee, USN.
On 22 July 1974, a tragic military blunder occurred during the brief conflict on Cyprus, in which a
Turkish plane or planes, bombed and sank a Turkish destroyer mistaken for part of an invading
force from Greece.
