# Naval Base Eniwetok

Naval Base Eniwetok was a major United States Navy base located at Enewetak Atoll in the Marshall Islands, during World War II. The base was built to support the island-hopping strategy used by allied nations fighting the Empire of Japan in the Pacific War. During 1944-5 Eniwetok was one of the busiest naval bases in the world with over 488 ships.

## History

Enewetak (also spelled Eniwetok) Atoll is a large coral atoll with a lagoon circled by 40 islands in a 50-mile (80 km) circumference. The islands have less than 2.26 square miles (5.9 km$^2$) of land that is only a few feet above sea level. The deep lagoon in the atoll offers excellent fleet anchorage for the largest ships. The lagoon has only three entrances, providing control and protection. After World War I, Eniwetok became part of Japan under the South Seas Mandate. In November 1942, the Empire of Japan built an airfield on Enewetak Atoll's Engebi Island, to refuel and support planes at Truk. In the United States' Marshall Islands campaign, the US took control of the Marshall Islands and the Imperial Japanese Army sent the 1st Amphibious Brigade with 2,586 men to defend the base on Engebi Island and Parry Island. In the Battle of Eniwetok, the US took Eniwetok, starting on 17 February 1944, and ending 23 February. The action took place on three islands: Engebi, Parry, and Eniwetok by the US 22nd Marines and the Army's 106th Infantry. Medical dispensaries were built on each of the main islands: Eniwetok, Engebi, and Parry islands, with a total of 200 beds.

## Engebi Airfield

On Engebi Island was a runway built by Japan. The US Army 47th Engineers repaired and improved the runway starting February 1944 and completing 10 March. The Engebi Airfield was named Wrigley Airfield. Four fighter squadrons used the 3,950-foot by 225-foot runway. At the airbase were an engine-overhaul shop and a 146,000 gallons aviation-gasoline tank farm. The Army had the 41st Bomber Group and 396th Bomber Squadron flying B-25. Marine Aircraft Group 31 and VMF-113 also used the Engebi Airfield, flying Vought F4U Corsair. In September 1944 Charles Lindbergh visited Engebi Airfield and United States Marine Corps flew the Corsairs. Charles Lindbergh helped improve the maximum ordnance load of the Corsairs. By June 1944, the major projects on Engebi had been completed and Construction Battalion Maintenance Unit 594, CBMU 594, took over. Engebi Island was given the code name Janet and is at 11°39′46″N 162°14′24″E﻿ / ﻿11.662887°N 162.240124°E﻿ / 11.662887; 162.240124. The airfield was abandoned at the end the war.

## Eniwetok Island

US Navy Seabees with the 110th Naval Construction Battalion arrived at Eniwetok starting 21 February 1944. The Seabee's first task was clearing the runway of battle damage and repairing the runway to be a bomber airbase for the United States Army Air Forces. The completed runway, Stickell Field, was 6,800-by-400-foot (2,070 by 120 m) wide on Eniwetok Island. The first plane landed on 11 March, and the first attack mission was carried out on 5 April. Seabees built air facilities that included a major engine overhaul depot, and barracks for Army aviation personnel with quonset huts. The most common bombers were Consolidated B-24 Liberator and North American B-25 Mitchell.
The US Navy also used Stickell Field, with unit VD-3 flying PB4Y, Navy Liberator. The Navy had stationed at base unit VB-109, VD-4, and VPB-109 flying Lockheed Ventura Harpoon-PV-1 and Consolidated PB4Y-2 Privateer. Stickell Field is named after Lt. John H. Stickell, a US Navy and former RAF pilot. John H. Stickell was killed in 1944 in action against the Jaluit Atoll.
Seabees built a large tank farm with twelve 1,000-barrel tanks to fuel the bombers with aviation gasoline at Stickell Field. Tankers in the lagoon could refill the tanks by a floating pipeline that was 1,200 feet long at a tanker mooring. The tank farm was completed by May 1944. It was partly damaged when a Landing craft tank, LCT(5)-315, had an explosion on 23 March 1944.
Seabees also built two (80-foot and 150-foot) coral-fill piers out into the lagoon on Eniwetok Island for unloading supplies. They also built tow beach ramps for unloading LCTs. In addition, Seabees built two berths that were used for ships to dock and do anti-aircraft target practice. For target practice, the airbase would provide a towed target and also had drone planes tow targets for safety.
3,500 troops were stationed on Eniwetok Island in 1944. Naval Base Eniwetok Fleet Post Office Box's number was 3237. Eniwetok Island was given the code name Fred at 11°20′21″N 162°19′21″E﻿ / ﻿11.339243°N 162.322457°E﻿ / 11.339243; 162.322457. After the war, the runway became Enewetak Auxiliary Airfield, now an emergency landing runway. Hal Kanter built and ran Armed Forces Radio Service radio station on Naval Base Eniwetok.

### Bob Hope

In 1944 Bob Hope put on a Bob Hope Show on Eniwetok Island. In the USO military tour there were still wrecked planes and equipment in the background. Hope had Jerry Colona and Frances Langford sing on stage. Patty Thomas danced and musician guitarist Tony Romano played. Hope called his 1944 tour of the South Pacific: "Loew’s Malaria Circuit" and "the Pineapple Circuit". Hope did 150 shows in the two months they were on the 1944 road trip. Hope's 1944 show visited Naval Base Pearl Harbor Hawaii at the Nimitz Bowl, Eniwetok, Naval Base Cairns, Green Islands, Bougainville, Milner Bay, Naval Base Treasury Islands, Naval Base Mios Woendi called Wendy Island, and Naval Base Kwajalein.

## Parry Island

Troops at sea on ships and boats need R&R, so in June 1945, the 67th Naval Construction Battalion arrived and built a 35,000-man recreation center on Parry Island. Parry Island had mark off swimming beaches. At the recreation center in the atoll, the Navy had an ice cream barge that could make up to 500 gallons of ice cream for the troops in 8 hours. The ice cream barge also would make fresh bread products. The base officer's club was built on Parry Island. The base printed a bulletin newspaper to keep the Troops up-to-date at the base. After completion, the Construction Battalion Maintenance Unit 608 (CBMU 608) took over the day-to-day operation and Maintenance of the center. Naval Base Eniwetok was part of the vast Naval Base Marshall Islands. On Parry Island the 110th Battalion Seabees repaired and improved the Parry Island Seaplane Base captured from Japanese forces. Parry Island is also known as: Medren, Elmer, Igem, Heartstrings, and Overbuilt at 11°24′05″N 162°22′12″E﻿ / ﻿11.401322°N 162.370072°E﻿ / 11.401322; 162.370072.

## Smaller Islands

The local inhabitants, Micronesians, at Eniwetok were restricted to the smaller islands of Biijiri, Aomen, and the Rojoa complex. Aomen (Aranit, Ulie) codename was Sally. Biijiri, Bijire codename was Tilda. One of the small islands, that was away from the base and inhabitants, for safety, was used as an ammunition depot. Seabees of the 126th Battalion built a second fleet recreation center on Runit Island, codename Hawthorne, six weeks later it was crated up and shipped to Naval Base Ulithi. The 126th Battalion also built facilities on Japtan, codename, David.

## Eniwetok lagoon

The deep lagoon the Navy set up fleet anchorage and a major US Naval Advance Base. The USS Cascade (AD-16) became the flagship of Service Squadron 4 and Service Squadron 10. A Service Squadron is a floating Naval Base, with all the support a land base would give. In the Service Squadron were all the supplies and repair depot support the fleet needed. The Service Squadron had: Fleet Oilers (AO), Gasoline Tanker (AOG), Repair Ships (AR), Ammunition ships (AE), Destroyer Tenders (AD), Tugboats, Barges, Seaplane tenders,hospital ship (AH), Net laying ships (AN), barracks ships (APL), Small Auxiliary Floating Dry Docks, stores ship, and Submarine tenders (AS). By July 1944 there were about 488 at the base, after a fleet depart there were 283. ships. Seabes built a signal tower at the entrance to the lagoon, that became the Harbor Entrance Control Post (HECP), to direct port traffic. The USS Vega (AK-17) was used to assemble floating pontoon barges. Shipping Pontoons flat and unassembled took a lot less space. Outboard engines were added to many barges for moving supplies in the atoll.
As the fighting front moved east and closer to Japan, Service Squadron 10 was too far away from the action. Service Squadron 10 started departing Enewetak Atoll on 4 October 1944 for Naval Base Ulithi arriving on the 15th. Ulithi is 1,538 miles west of Eniwetok. Squadron 10 was moved to Ulithi in four convoys, tugboats returning to move non-self-propelled craft for each trips. Non-self-propelled craft included: APL-14 troopsship, 7 concrete 3,000-ton storage barges, 19 oil/water barges, 17 gasoline barges, 24 500-ton barges with ammunition, freight, spare parts, radio, medical, mail, refrigerated food, etc. The Service Squadron 10 move took 2 weeks.

### Eniwetok repair depot

The US Navy set up a large ship and boat repair depot at Naval Base Eniwetok. The repair depot provided the fleet with support to keep ships and subs tactically available in the Pacific War with the repair and supply depot, rather than ships having to return to continental United States. The Navy had built special auxiliary floating drydocks that were able to repair battle damage to even the largest ships and do regular maintenance in the field saving ships trans-pacific travel time for repair. Supply store ships were also at the base with the parts needed to keep the fleet ready. The USS Endymion (ARL-9) was torpedoed and had temporary repairs made at Eniwetok. In September 944 a strong westerly storm hit Eniwetok, damaging many boats and barges and driving high-speed target rafts ashore. The depot worked overtime to repair the damage.

### Eniwetok seaplane base

The Parry Island seaplane base had only one seaplane ramp and it was not usable at low tide. Most of the seaplane base operations were carried out by seaplane tenders in the lagoon. Seaplanes did reconnaissance patrols and search, also rescue missions for downed aircrew men and survivors of sunk ships. The most common seaplanes at the base were Consolidated PBY Catalina and Martin PBM Mariner. The seaplane base take off and landing was a spot was marked off in the atoll. The seaplanes were supported by a floating base of seaplane tenders. Seaplane tenders had stores to supply: food, fuel, ammo, spare parts. The seaplane tender also had housing and mess halls for the aircrew while the seaplane was being serviced. Aircrew on leave could go to Eniwetok's fleet recreation center. Some seaplane tenders were stationed at Eniwetok seaplane base for months. Other seaplane tenders came to Naval Base Eniwetok to resupply the ship's stores before returning to a US Naval Advance Base. Some came to Eniwetok repair depot to be repaired.

### Eniwetok destroyer base

Hundreds of US Navy destroyers were used in the Pacific war. Destroyers were used to protect capital ships like aircraft carriers, battleships and heavy cruisers. Destroyers were used to screen and protect convoy of ships. Destroyers were used to hunt submarines and protect amphibious landings at beaches. Destroyers had anti-aircraft guns, radar, and forward-launched ASW weapons, dual-purpose guns, depth charges, and torpedoes. Destroyers needed to be restocked with food, fuel, supplies, and weapons to keep operational. Eniwetok had a large destroyer base, with destroyer tenders. These ships could do minor repair work with major work done at the Eniwetok repair depot.
* Destroyer tenders stationed at Eniwetok:
* USS Cascade (AD-16)
* USS Prairie (AD-15)

* USS Markab

### Eniwetok Submarine Base

Many US Navy submarines were used in the Pacific War. The submarine attacked warships and sank supply ships that were needed by Japan to resupply their many bases in the Pacific. US subs also did reconnaissance patrols, landed guerrilla special forces and search and rescue missions for downed aircrew men. US submarine had long ranges, but needed to be resupplied with fuel, food, torpedoes and deck gun shells. At Naval Base Eniwetok the Navy set up a floating submarine base in the atoll. The submarine tenders: USS Sperry (AS-12) and USS Beaver were stationed in the atoll to supply the submarines. While the submarine was being resupplied, and repaired if needed, crews could have a break (R&R) at the atoll's fleet recreation center. Some of the subs stationed at the base were: USS Tunny (SS-282), USS Salmon (SS-182), USS Darter (SS-227), USS Spearfish (SS-190), USS Scabbardfish (SS-397), USS Sargo (SS-188), USS Thresher (SS-200), USS Tilefish (SS-307), and USS S-35 (SS-140).

### Eniwetok floating hospital

Naval Base Eniwetok was used as a major forward Naval hospital. US Navy Hospital ships were stationed Naval Base Eniwetok during parts of the war and some were stationed shortly as they joined staging for upcoming invasions. Hospital ships also were able to resupply and refuel at the base.
* USS Relief (AH-1), 550-beds, stationed at Eniwetok September 1944, to help with a dysentery outbreak at the atoll.
* USS Mercy (AH-8), up to 400 patients
* USS Hope (AH-7), up to 400 patients
* USS Solace (AH-5) up to 418 patients

### Net Laying

To protect the many ships at Eniwetok the Navy had anti-torpedo net installed. The ship USS Tuscana (AKN-3) supplied the nets. The ships also installed the moorings at Eniwetok.
* Net laying ships stationed at Eniwetok:
* USS Anaqua

### Submarine chaser base

To help protect the base and shipping around the base, Naval Base Eniwetok had a fleet of submarine chasers. The submarine chasers were supported by a submarine chaser tender ship: the USS Mindanao (ARG-3) was stationed at Eniwetok to support the fleet of submarine chasers and some crash boats. crash boats were fast boats use to rescue downed airmen. Some of the submarine chasers served at Eniwetok: PC-1080, USS PC-1137, USS PC-1142, USS PC-1136, USS PGM-18, USS PC-1138, USS Winnemucca (PC-1145), and USS PC-598.

## Fleet support

Naval Base Eniwetok was used for the Admiral Raymond A. Spruance's United States Fifth Fleet anchorage. Ships in the Fifth Fleet were able to resupply, and refuel from Seron Ten, (Service Squadron 10). Resupply included food, freshwater for small crafts, spare parts and ammunition. Troops were able to have liberty leave at the fleet recreation. Eniwetok was used for staging upcoming missions. Eniwetok had a depot, tenders and repair ships for servicing amphibious ships and amphibious crafts in the southern anchorage, later moved to eastern anchorage. Eniwetok was the staging for the Marianas invasion, three hundred vessels supplied before departure. VPB-13 was staged at Eniwetok for weeks before the Guam campaign. Eniwetok also had spare fighter planes and parts for the aircraft carriers. The USS Bowditch (AG-30) had surveyed the lagoon to find the best mooring for large and small ships. USS Bowditch also placed the navigational markers for entrance and path through the atoll. The Fifth Fleet also used Naval Base Majuro and Naval Base Ulithi for resupply. After Naval Base Guam was re-established some of Seron Ten ships departed to support the new base there.

## LORAN station

The United States Coast Guard built a LORAN (Long Range Navigational Signal) station at Eniwetok in January 1951. The station closed 1978, as in 1978 the Global Positioning System replaced the need for LORAN.

## Post war

From 14 April 1948 through 18 August 1958, the United States conducted nuclear weapons testing at Eniwetok Atoll, exploding over 30 megatons. From 1977 to 1980, the US constructed a concrete dome on Runit Island, under which radioactive soil and debris were deposited.
