'''USS ''Tripoli'' (CVE-64)''' was a {{sclass|Casablanca|escort carrier}} of the [[United States Navy]]. ''Tripoli'' is the first US Navy ship named for the [[Battle of Derne]] in 1805. It was the decisive victory of a mercenary army led by a detachment of [[United States Marine Corps|United States Marines]] and [[U.S. Army|soldiers]] against the forces of [[Ottoman Tripolitania|Tripoli]] during the [[First Barbary War]]. It was the first recorded land battle of the United States fought overseas.<ref>{{Cite web|url=http://www.history.navy.mil/research/histories/ship-histories/danfs/t/tripoli-i.html|title=Tripoli I (CVE-64)}}</ref>

==Construction==
She was built under a [[Maritime Commission]] (MARCOM) contract (MC hull 1101) at [[Vancouver, Washington]], and was laid down by the [[Kaiser Shipyards]] on 1 February 1943, as '''''Didrickson Bay''''' ('''ACV-64'''). Renamed ''Tripoli'' on 3 April 1943, and launched on 13 July 1943, sponsored by Mrs. Leland D. Webb, and commissioned on 31 October 1943, at [[Astoria, Oregon]].

==Service history==

===World War II===
Following shakedown training off the [[California]] coast, the escort carrier entered the repair base at [[San Diego, California]]. There, on 4 January 1944, [[gasoline]] was inadvertently dumped into the water around the forward part of the ship, on the starboard side. [[Acetylene torch]] sparks ignited the volatile mixture, and flames quickly spread from the bow to frame 82, engulfing the forward galley walkway and the island superstructure. Yardcraft and the ship's crew battled the flames and soon had the fire under control, but not before two men had died.

====Atlantic====
Subsequently repaired, ''Tripoli'' departed San Diego on 31 January, bound for the [[Panama Canal]] and duty with the Atlantic Fleet. She arrived at her new home port, Norfolk, Virginia on 16 February. Embarking Composite Squadron 13 ([[VC-13]]) - 13 [[Grumman F4F Wildcat|Grumman FM-2 Wildcat]]s and [[Grumman TBF Avenger|Grumman TBM Avenger]]s - the carrier put to sea on 15 March as the center ship in Task Group 21.15 (TG 21.15). Supported by five destroyer escorts of Escort Division 7 (CortDiv 7), ''Tripoli'' patrolled west of the [[Cape Verde Islands]] to break up [[German U-boat]] refuelling activities in that area.

After providing air cover for a convoy routed to the [[British West Indies]], ''Tripoli''{{'}}s Wildcats and Avengers searched the sea lanes northwest, southwest, and west of the Cape Verdes before putting into [[Recife]], [[Brazil]] on 5 April, to refuel and provision. Back at sea again two days later, ''Tripoli'' continued the routine of daily launchings and recoveries of her aircraft, guarding the Allied sea lanes against the incursions of enemy U-boats.

About one hour before sunrise on 19 April, one of ''Tripoli''{{'}}s Avengers made radar contact with a German U-boat as the submarine cruised on the surface awaiting the arrival of her "[[German Type XIV submarine|Milch Cow]]" or refuelling partner. {{GS|U-513||2}} put up a spirited anti-aircraft barrage while the Avenger made three attacks. A pattern of rockets bracketed the submarine on the first pass as the Germans prepared to dive for comparative safety. On the second run, the aircraft's depth charges failed to release, giving the enemy submersible the time she needed to dive. The U-boat evaded the aircraft's last attack - a mine - but also missed her fuelling rendezvous with {{GS|U-488||2}}.

Returning to Norfolk on 29 April, ''Tripoli'' underwent voyage repairs before embarking [[VC-6]] - 12 Avengers and nine Wildcats. She then formed up with CortDiv 7 and departed Hampton Roads on 24 May for further searches in the vicinity of the Cape Verdes. Four days out, she changed course to intercept a German submarine estimated to be proceeding southwest from a position west of the [[Madeira Islands]]. When no contact was made by 30 May, ''Tripoli'' and her consorts steamed north to rendezvous with a convoy bound for [[Nova Scotia]].

Following her return to Norfolk on 18 June, ''Tripoli'' spent two months in carrier qualification training off [[Quonset Point]], Rhode Island, before making port again at Norfolk on 15 July. Embarking Composite Squadron 6, she conducted two weeks of pilot qualifications in the [[Chesapeake Bay]] area before departing [[Hampton Roads]] on 1 August, bound for her new base of operations, Recife.

Screened by {{USS|O'Toole|DE-527|2}} and {{USS|Edgar G. Chase|DE-16|2}}, the escort carrier proceeded south until 1 August, when ''O'Toole'' developed a sonar contact and gave chase. Aircraft from ''Tripoli'' laid patterns of [[sonobuoy]]s at the initial contact point and dropped smoke floats and float lights on an oil slick. Picking up the "scent", ''O'Toole'' straddled the floats with her [[Hedgehog (weapon)|Hedgehog]] projectiles and depth charges and soon radioed victoriously "We hit the rodent!" A brief visual examination of the evidence - debris and a large quantity of diesel oil - satisfied the hunter-killer group that they had indeed sunk an enemy submarine. However, a post-war examination of German records did not confirm the kill. As night fell, ''Tripoli'' vectored two aircraft to another sonar contact by ''O'Toole'', and four depth bombs were dropped -  keeping another U-boat down and running.

''Tripoli'' and her group then returned to Recife on 13 August, and reported for duty with Admiral [[Jonas H. Ingram]]'s [[United States Fourth Fleet|4th Fleet]]. Designated as the center of TG 47.7, the escort carrier put to sea on 22 August with the four destroyer escorts of CortDiv 24 to operate against a homeward-bound German submarine estimated to pass at 25° south latitude and 5° west longitude.

After a fruitless search pursuing two fading sonar contacts in the mid-South Atlantic narrows, ''Tripoli'' and her group returned to Recife on 11 September for provisioning and fuelling. Underway again two days later, TG 47.7 headed out to conduct another search - this time along the estimated track of two U-boats slated to rendezvous for refuelling. One of the target U-boats was {{GS|U-1062||2}}, bound from [[Penang]], [[British Malaya]] with a cargo of valuable petroleum products for the German war effort. Ordered to fuel{{GS|U-219||2}}, outward-bound for the Far East, ''U-1062'' prepared to rendezvous with her smaller sister boat in the South Atlantic narrows - directly in the path of the ''Tripoli'' escort group.

Passing to the westward of the Cape Verdes, TG 47.7 made rendezvous with {{USS|Mission Bay|CVE-59|2}}{{'}}s escort group to conduct a joint hunter-killer operation against the two enemy boats. Round-the-clock searches by radar-equipped Avengers continued until 40 minutes after sunset on 28 September, when an Avenger piloted by Lieutenant William R. Gillespie reported a definite contact with the surfaced ''U-219'' only 11 miles from the enemy's estimated track.

Gillespie went in to conduct a low-level rocket attack, but was shot down by heavy flak. Another Avenger, drawn to the battle, braved the flak to conduct another rocket run and also dropped depth bombs, while a Wildcat strafed the U-boat which struggled desperately to dodge the harassing attacks by the American aircraft.

''U-219'' emerged from the firefight unscathed, but ''U-1062'' did not enjoy similar good fortune. {{USS|Fessenden|DE-142|2}}, one of ''Mission Bay''{{'}}s screen, homed in on sonobuoy indications on 30 September and sank the "Milch Cow" with a four-charge pattern. In the meantime, ''U-219'' was not yet home free - one of ''Tripoli''{{'}}s Avengers dropped depth bombs on the fleeing boat on 2 October. American sonar-men felt that they had definitely "killed" the U-boat, but post-war accounting showed that ''U-219'' had escaped to [[Jakarta|Batavia]], [[Java]].

When fuel supplies ran low, ''Tripoli'' returned to Recife on 12 October. She conducted one further search of the narrows from 26 October-12 November before heading for a much-needed overhaul at Norfolk. Subsequently, the escort carrier sailed for the Pacific and, after transiting the Panama Canal and touching at [[San Diego]], arrived at Pearl Harbor on 10 January 1945.

====Pacific====
''Tripoli'' transferred Composite Squadron 8 ashore to conduct operations from [[Hilo]], [[Hawaii]], before she loaded a miscellaneous cargo of fighters and bombers to be offloaded at Roi, in the [[Marshall Islands]], where she made port on 20 February 1945. Returning to Pearl Harbor after this ferry run, the escort carrier commenced training operations which would continue through the end of the war, and into late 1945. With Japan's surrender and the end of hostilities in the Pacific, ''Tripoli'' was assigned to [[Operation Magic Carpet]].

Arriving at San Diego on 29 August, with 500 Navy veterans, ''Tripoli'' returned to [[Pearl Harbor]] on 8 September, before resuming local operations - including night carrier qualifications - through November. She subsequently made one trip with Army passengers to [[San Pedro, California]], and a further "Magic Carpet" run to San Diego. The carrier departed the west coast on 15 January 1946, for deactivation overhaul at Norfolk. On 22 May 1946, the need for her services not required, ''Tripoli'' was decommissioned and laid up in reserve.

===Korean War===
The outbreak of the [[Korean War]] in the summer of 1950 resulted in the return of many of the Navy's reserve ships to active service to support American operations in the Far East. Accordingly, ''Tripoli'' was recommissioned at New York on 5 January 1952. Assigned to the [[Military Sealift Command]] (MSC), Atlantic Area, the former "hunter-killer" began her new career as an aircraft transport and ferry.

[[File:USS Tripoli (CVE-64) transporting F-84s in the 1950s.jpg|thumb|''Tripoli'' transporting F-84 Thunderjets in the 1950s.]]

Over the next six years, ''Tripoli'' conducted 44 transport voyages, mostly to European and Mediterranean ports, but with one visit to Hawaii and two to the Far East. Following the ship's third voyage to Europe, ''Tripoli'' was berthed at the Port Newark Terminal on 5 August 1952, where she loaded 45 [[F-84 Thunderjet]]s, 90 wingtip fuel tanks, and related gear for transport to the Far East. After going to sea on 7 August, bound for Japan, ''Tripoli'' steamed via the Panama Canal and San Diego and made port at [[United States Fleet Activities Yokosuka|Yokosuka]] with her vital cargo on 5 September, where cranes lifted the reinforcements ashore - soon to be in action in their ground-attack role in Korea. After loading battle-damaged aircraft for repairs in the United States, the carrier embarked 245 Navy and Marine Corps personnel for rotation back to [[Alameda Naval Air Station]], California. Making port on the West Coast on 22 September, she then put to sea for the Far East a second time, once again carrying jet aircraft to Yokosuka, as well as transporting men of the Sea Echelon of Boat Unit 1. Loading a cargo of helicopters and military passengers, ''Tripoli'' returned to the west coast and arrived at Alameda on 11 November 1952. Subsequently making her sole Hawaiian voyage with the MSC, ''Tripoli'' then headed east to finish her career with transport voyages to European and Mediterranean ports.

At Alameda May 1954, fifty F-86D aircraft were loaded on board ''Tripoli'' and cocooned for a 21-day trip thru the Panama Canal to St Nazaire, France. 13 June approx 500 US Air Force personnel of the 440th FIS from Spokane WA and 441st FIS from Hamilton AFB in San Francisco, CA boarded the ship. One source identifies the units as the [[496th Tactical Fighter Squadron|496th Fighter Squadron]] from Hamilton AFB, and the 440th from [[Geiger Field|Geiger Air Force Base]].<ref>United Press, "Interceptor Fighters on Way To Europe", ''San Bernardino Sun-Telegram'', San Bernardino, California, Sunday 6 June 1954, Volume VIII, Number 9, page 2.</ref> On 2 July the ship arrived at the port of St Nazaire, France. The two squadrons were bound for Landstuhl AFB, Germany.

Receiving "smart ship" awards from in the intervening years, ''Tripoli'' was reclassified a utility carrier and redesignated '''CVU-64''' on 12 June 1955. Again redesignated '''T-CVU-64''' on 1 July 1958, ''Tripoli'' was decommissioned at [[New Orleans]], La., on 25 November 1958 and subsequently struck from the [[Naval Vessel Register]] on 1 February 1959. Her hull then scrapped by a Japanese firm in January 1960.
