USS Savo Island (CVE-78) was the twenty-fourth of fifty Casablanca-class escort carriers built for the United States Navy during World War II. She was named to memorialize the U.S. casualties of the Battle of Savo Island, which was fought as part of the Guadalcanal campaign. The ship was launched in December 1943, commissioned in February 1944, and served as a frontline carrier throughout the Mariana and Palau Islands campaign and the Philippines campaign. During the Battle of Okinawa, she provided air cover for the replenishment carrier fleet. Postwar, she participated in Operation Magic Carpet, repatriating U.S. servicemen from throughout the Pacific. She was decommissioned in December 1946, when she was mothballed in the Atlantic Reserve Fleet. Ultimately, she was sold for scrapping in February 1960.

Description and construction - Casablanca-class escort carrier

Savo Island was a Casablanca-class escort carrier, the most numerous type of aircraft carriers ever built,^[2] and designed specifically to be mass-produced using prefabricated sections, in order to replace heavy early war losses. Standardized with her sister ships, she was 512 ft 3 in (156.13 m) long overall, at the waterline, she was 490 ft (150 m) long, she had a beam of 65 ft 2 in (19.86 m), at her widest point, this was 108 ft (33 m), and a draft of 20 ft 9 in (6.32 m). She displaced 8,188 long tons (8,319 t) standard, 10,902 long tons (11,077 t) with a full load. She had a 257 ft (78 m) long hangar deck and a 477 ft (145 m) long flight deck. She was powered with two Skinner Unaflow reciprocating steam engines, which drove two shafts, providing 9,000 shaft horsepower (6,700 kW), thus enabling her to make 19 knots (35 km/h; 22 mph). The ship had a cruising range of 10,240 nautical miles (18,960 km; 11,780 mi) at a speed of 15 knots (28 km/h; 17 mph). Her compact size necessitated the installation of an aircraft catapult at her bow, and there were two aircraft elevators to facilitate movement of aircraft between the flight and hangar deck: one each fore and aft.^[3][2][4]

One 5-inch (127 mm)/38 caliber dual-purpose gun was mounted on the stern. Anti-aircraft defense was provided by eight Bofors 40-millimeter (1.6 in) anti-aircraft guns in single mounts, as well as 12 Oerlikon 20-millimeter (0.79 in) cannons, which were mounted around the perimeter of the deck.^[4] By the end of the war, Casablanca-class carriers had been modified to carry thirty 20 mm cannons, and the amount of 40 mm guns had been doubled to sixteen, by putting them into twin mounts. These modifications were in response to increasing casualties due to kamikaze attacks. Although Casablanca-class escort carriers were designed to function with a crew of 860 and an embarked squadron of 50 to 56, the exigencies of wartime often necessitated the inflation of the crew count. Casablanca-class escort carriers were designed to carry 27 aircraft, but the hangar deck could accommodate more. During the Mariana and Palau Islands campaign, she carried 16 FM-2 fighters, and 12 TBM-1C torpedo bombers, for a total of 28 aircraft.^[5] During the Battle off Samar, she carried 17 FM-2 fighters and 12 TBM-1C torpedo bombers, for a total of 29 aircraft.^[6] During the Battle of Mindoro, she carried 24 FM-2 fighters and 9 TBM-1C torpedo bombers, for a total of 33 aircraft.^[7] During the Battle of Lingayen Gulf, she carried 19 FM-2 fighters and 12 TBM-1C torpedo bombers, for a total of 31 aircraft.^[8] During the Battle of Okinawa, she carried 20 FM-2 fighters and 12 TBM-3 torpedo bombers, for a total of 32 aircraft.^[9]

Construction

Her construction was awarded to Kaiser Shipbuilding Company, Vancouver, Washington under a Maritime Commission contract, on 18 June 1942. The escort carrier was laid down on 27 September 1943 under the name Kaita Bay, as part of a tradition which named escort carriers after bays or sounds in Alaska.^[10] She was laid down as MC hull 1115, the twenty-fourth of a series of fifty Casablanca-class escort carriers. She was renamed Savo Island on 6 November 1943, as part of a new naval policy which named subsequent Casablanca-class carriers after naval or land engagements.^[11] She was launched on 22 December 1943; sponsored by Miss Margaret Taffinder; transferred to the United States Navy and commissioned on 3 February 1944, with Captain Clarence Eugene Ekstrom in command.^[1][12]

USS Savo Island (CVE-78): Detailed Overview

The USS Savo Island (CVE-78) was a Casablanca-class escort carrier constructed during World War II. Commissioned on February 3, 1944, she was named after the Battle of Savo Island, a pivotal naval engagement in the Guadalcanal Campaign. Like her sister ships, Savo Island was designed to provide air support to amphibious landings, protect convoys, and support fleet operations. Her contributions earned her four battle stars and a Presidential Unit Citation for her role in the Philippines Campaign. Below is a detailed analysis of her features.

Flight deck arrangements

The flight deck of the USS Savo Island measured 512 feet 3 inches in length and 108 feet wide, with a deck optimized for compact operations due to its smaller size compared to fleet carriers. It featured a single hydraulic catapult, which facilitated aircraft launches in a timely manner, critical for rapid air operations during battle. Two elevators were installed, each capable of transporting aircraft between the hangar and flight decks quickly to maintain a continuous flow of sorties. The carrier was designed to embark around 27 aircraft, including fighters such as the Grumman FM-2 Wildcat and torpedo bombers like the TBM Avenger. Despite its smaller size, the flight deck was equipped with advanced arresting gear and barriers to safely recover aircraft. Modifications over her service life included improvements to her deck lighting and navigation aids to enhance her night operation capabilities, which became increasingly important as night-fighting tactics evolved.

Propulsion

The propulsion system of Savo Island was designed for efficiency rather than high speed, aligning with her role as an escort carrier. She was powered by two Skinner Unaflow reciprocating steam engines, which were fed by four Babcock & Wilcox boilers. This arrangement produced a combined 9,000 shaft horsepower, driving two screws and allowing the carrier to reach a maximum speed of 19 knots.

While slower than fleet carriers, this speed was sufficient for her escort and support roles. Her range of approximately 10,240 nautical miles at 15 knots enabled her to operate for extended periods without refueling, a critical attribute in the vast expanses of the Pacific. The propulsion system was reliable and efficient, allowing her to maintain station with task groups and convoy formations.

Armament

The USS Savo Island was heavily armed for an escort carrier, reflecting the increased threat of kamikaze attacks and air raids during her service. Her original armament included one 5-inch/38-caliber dual-purpose gun mounted on the stern, capable of engaging both surface and aerial targets. She was also equipped with eight 40 mm Bofors anti-aircraft guns, which were arranged in twin mounts for medium-range defense.

Additionally, the carrier had 12 20 mm Oerlikon cannons strategically placed around the flight deck and superstructure to provide close-in protection against enemy aircraft. As the war progressed and the kamikaze threat intensified, Savo Island received upgrades to her anti-aircraft suite, with more Oerlikon cannons added to bolster her defensive capability. These weapons enabled her to defend herself and contribute to the protective screen for the ships in her task group.

Fire control and electronics

The Savo Island was outfitted with state-of-the-art radar systems for both air and surface search, crucial for early detection of enemy threats. These included air search radar to identify incoming aircraft at long ranges and surface search radar to track ships and low-flying planes. Her radar systems were integrated with fire control mechanisms, allowing her anti-aircraft guns to engage targets with improved accuracy.

Her communication systems ensured effective coordination with her embarked air group and other ships in her task force. Throughout her service, advancements in electronic warfare led to the installation of more sophisticated radar and communications equipment, enabling her to adapt to the evolving nature of naval warfare.

Armor

The USS Savo Island was lightly armored, in keeping with her design as an escort carrier. Her vital areas, such as the machinery spaces and magazines, were protected by armor plating. However, the flight deck itself was unarmored, which made it vulnerable to direct hits from bombs or kamikaze aircraft.

This vulnerability was mitigated by her defensive armament and the protective screens provided by escorting destroyers and cruisers. Despite her light protection, Savo Island demonstrated resilience in combat, enduring near-miss attacks and continuing her operations without significant disruptions.

The USS Savo Island served with distinction in the Pacific, providing critical air support during key battles such as Leyte Gulf and Okinawa. Her adaptability and robust design made her a valuable asset, underscoring the effectiveness of Casablanca-class escort carriers in World War II. Following her decommissioning on December 12, 1946, her legacy as a hardworking and reliable escort carrier was firmly cemented in naval history.

Service history - World War II

USS Savo Island (CVE-78) arrived at Guadalcanal carrying a load of P 38 Lightning 10th July 1944

Upon being commissioned, Savo Island underwent a shakedown cruise down the West Coast to San Diego, where she took on a load of replacement aircraft. Between 15 March 1944 and 2 July, she underwent two transport missions, ferrying aircraft to bases in the Southwest Pacific. On 6 July, she embarked Composite Squadron (VC) 27, which would be her aircraft contingent throughout the Marianas and Palau Islands campaign and the Philippines campaign of 1944–45. After a brief period of training off the waters of San Diego, she sailed west to Pearl Harbor, where similar exercises were conducted. There, on 4 August, she was assigned to Task Group 32.7, the Western Escort Carrier Group, commanded by Rear Admiral William Sample, of the Third Fleet, assigned to support the planned landings on the island of Peleliu, in the Palau Islands. Her aircraft contingent began combat operations on 11 September, strafing and bombarding the island to soften up the defenses for the landings. Following the landing of marines, her aircraft transitioned into providing close air support and patrol missions, up until 30 September.^[5][12]

On 3 October, she was assigned to and joined Task Group 77.4, which was gathering at Manus Island, in the Admiralty Islands, as part of the Seventh Fleet. She, accompanied by eighteen other escort carriers and their screens of battleships, cruisers, and destroyers, steamed on 12 October for Leyte Gulf, where they were expected to support the landings on Leyte, which marked the beginning of the Philippines campaign. As a part of Task Unit 77.4.2, otherwise known as 'Taffy 2', commanded by Rear Admiral Felix Stump, she was positioned to the direct south of 'Taffy 3', which was located to the direct east of the San Bernardino Strait. Arriving off the island on 18 October, her aircraft began carrying out naval patrols and strikes against predesignated targets. Once the Sixth Army had landed on 20 October, her aircraft transitioned towards a focus on close air support, supporting the initial advances for the next few days.^[6][12]

On 23 October, the Battle of Leyte Gulf began. Almost the entirety of Japan's remaining surface fleet had been concentrated into a counterattack against the U.S. forces in the vicinity of the Philippines, which had threatened to cut off Japan's vital oil supply from Southeast Asia. Split into three groups, the Southern Force was defeated in the Battle of Surigao Strait, whilst Vice Admiral William Halsey Jr. sent the Third Fleet in an attack against the diversionary Northern Force. Therefore, the escort carriers which continued providing ground support had no capital ship screening, even as Vice Admiral Takeo Kurita's Center Force drove through the San Bernardino Strait during the night.^[13] On the early morning of 25 October, the Center Force emerged into the waters of Leyte Gulf, catching Taffy 3, some 20 mi (32 km) north of Savo Island, by surprise.^[14][12]

As the American command came to an understanding of the severity of the situation, with the Center Force consisting of four battleships, six cruisers, and a large destroyer screen, the entirety of Taffy 2's aircraft were recalled to join the defense. Savo Island's fighters and torpedo bombers were not equipped to attack surface ships, with most of her bombers being loaded with incendiary bombs and missiles for ground attacks.^[15] Nonetheless, aircraft from Savo Island's VC-27 were amongst Taffy 2's first wave of strikes, launched at 7:37 in the morning. Some of the destroyers within Taffy 2's screen wandered north, before being confronted with some Japanese naval gunfire and being ordered to withdraw towards the escort carriers. Overall, Savo Island launched six strikes against the Japanese forces, with her aircraft notably landing a torpedo hit on a Japanese battleship and shooting down an Aichi E13A reconnaissance seaplane caught in the middle of the action.^[16][12]

Discouraged by the stiff resistance his Center Force had faced, including the loss of three cruisers, Kurita issued orders to withdraw in the late morning, sparing Taffy 3 from further destruction. As the Japanese forces withdrew, fighters from Savo Island took the opportunity to down four more Japanese planes.^[17] Nonetheless, the escort carriers underwent concentrated Japanese attack again in the afternoon, this time from the air, including some of the first usage of kamikaze suicide attacks. The carrier continued supporting ground operations until 30 October, when Taffy 2 was reorganized into Task Unit 77.4.4, and ordered to withdraw back to Manus Island to rearm and replenish.^[18] She sortied from Manus on 19 November, providing cover for convoys proceeding to Leyte Gulf from 22 November to 27 November, accompanied by two other escort carriers. Upon completing this task, she replenished at Kossol Roads, Palau, before she left on 10 December, this time in support of the landings on the island of Mindoro. Her aircraft provided air cover as the landing craft unloaded their troops, and provided close air support as they advanced. They also targeted air fields, from which kamikaze aircraft were beginning to make regular forays. The escort carriers were relieved by Army aircraft on 15 December, but she stayed offshore until 17 December because of indications of a Japanese surface raid, which never materialized. On 17 December, she steamed back to Manus Island.^[19][12]

At Manus Island, Savo Island was assigned to Task Unit 77.4.2., the San Fabian Carrier Group.^[8] On 27 December, the carriers, escorted by a large surface fleet, left Manus bound for Lingayen Gulf, to the west of Luzon. There, the carriers would support the 6th Army landings on Luzon. As a part of Task Unit 77.4.2., Savo Island would provide air support and cover for the I Army Corps, which would land around the San Fabian area. Pausing at San Pedro Bay, the carriers entered the Sulu Sea on 3 January 1945, where they began being harried by aircraft, circling around on radar. Japanese planes continued appearing around the periphery of the American forces throughout 4 January, but it was not until 17:00 in the evening that the Japanese forces coalesced into a kamikaze strike, attacking at 17:12, achieving complete surprise, and sinking Savo Island's sister Ommaney Bay.^[20]

The following day, on 5 January, the kamikazes returned. At 17:43 in the evening, the battleship New Mexico reported planes approaching from her starboard bow, and shortly afterwards, Savo Island's sister Manila Bay had been hit by two kamikazes, heavily damaging the ship. A few minutes after the attack on Manila Bay, a Nakajima Ki-43 kamikaze dove towards Savo Island. Engaged by several anti-aircraft batteries, the plane began trailing smoke some 800 yd (730 m) away from the carrier. As a reaction, Savo Island turned hard to starboard, whilst its 24 in (610 mm) searchlight was pointed at the aircraft to try to blind the pilot. The plane, moving erratically, passed between the carrier's mast and the whip antenna, shearing off the carrier's radar antenna, before diving into the sea.^[21][22]

On 6 January, the carriers proceeded into Lingayen Gulf, and started a heavy bombardment of Japanese defenses, flying 5,971 sorties in eleven days. On 9 January, the 6th Army moved onshore, encountering little resistance. Savo Island remained on station until 17 January, when the United States Air Force took over air operations on Luzon.^[23] She then proceeded south to operate to the northwest of Mindoro, to guard against any counterattacks on the American garrisons situated throughout the Northern Philippines, staying on station from 17 January until 29 January. During this period, on 19 January, Captain William Donald Anderson took command of the ship. Upon completing her patrols, she then provided cover for landings near Subic Bay on 29 and 30 January, before retiring to Ulithi, in the Caroline Islands, for repairs and replenishment. There, her aircraft contingent, Composite Squadron 27, was replaced with Composite Squadron 91, which had previously served upon Savo Island's sister Kitkun Bay. Upon receiving replacement pilots, she began a brief period of training exercises, before being assigned to Task Unit 52.1.1, in preparation for the Battle of Okinawa.^[9][12]

Transiting via Leyte, her aircraft provided air cover and patrols en route. On 26 March, along with two other escort carriers, she supported the 77th Infantry Division as it occupied the Kerama Islands. On 27 March, she began bombing the main island of Okinawa, with her fighters flying antiaircraft and antisubmarine patrols. On 7 April, the carrier left Task Unit 52.1.1., trading places with Shamrock Bay, part of Task Group 50.8, the Logistics Support Group.^[24] Therefore, from 7 to 16 April, she screened a replenishment convoy proceeding to the east of Okinawa. Upon the completion of that task, she continued providing close air support for American forces advancing down Okinawa. On 27 April, her aircraft bombed Sakishima Gunto, an island situated halfway between Okinawa and Formosa. On 29 April, Savo Island, along with her sisters Marcus Island and Saginaw Bay, were discharged from their task group, all sailing for overhaul in San Diego.^[25] Savo Island's aircraft contingent, Composite Squadron 91, was traded for her sister Makin Island's Composite Squadron (VC) 84.^[26][12]

After finishing overhaul, Savo Island began a transport mission from San Diego to Pearl Harbor, before transiting back to Alameda, California, on the West Coast. On 6 August, she departed for the Aleutian Islands, arriving on 15 August, right as the Surrender of Japan was announced. On 31 August, she headed, along with six other escort carriers, to support the occupation of Japan in northern Honshū and Hokkaidō. After finishing her duties, she returned to Pearl Harbor on 25 September, where she was assigned to the 'Magic Carpet' fleet, which repatriated servicemen from throughout the Pacific. She first loaded occupation troops bound for Japan at San Francisco, before heading west. Savo Island made a total of three 'Magic Carpet' voyages, repatriating troops from Guam, Pearl Harbor, and Okinawa, respectively. Upon arriving at Seattle on 14 January 1946, and finishing her final voyage, she transited to the Eastern seaboard, entering Boston Harbor on 16 March for inactivation.^[12]

Savo Island was decommissioned on 12 December, and mothballed in the Atlantic Reserve Fleet, as part of its Boston group. Docked at the South Boston Naval Annex, she was reclassified as a helicopter escort carrier (CVHE-78) on 12 June 1955. She was then further reclassified as an aviation transport (AKV-28) on 7 May 1959. She was struck from the Navy list on 1 September 1959, and she was sold on 29 February 1960 to Comarket Inc., which broke her up in Hong Kong throughout June 1960.^[4] Savo Island received 4 battle stars for her World War II service. In addition, she received a Presidential Unit Citation for her service in the Western Carolines, the Philippines, and Okinawa from 6 September 1944 to 29 April 1945. Clarence Ekstrom, the carrier's commander during the Battle of Leyte Gulf, later received the Navy Cross for his leadership and courage in the action.^[27][12]

In popular culture

While the Savo Island spent the Korean War in mothballs as part of the Atlantic Reserve Fleet, author James Michener fictionally had it in commission (as an Essex-class fleet carrier) and participating in that war as the primary setting for his novella The Bridges at Toko-ri. The 1954 movie version was filmed aboard the fleet carriers Oriskany and Kearsarge with Oriskany still displaying its hull symbol of CV-34, but the ship was still referred to as the Savo Island.^[28]
