Overview

Overview

Palmyra Atoll at a glance

The Kingdom of Hawaii claimed the atoll in 1862, and the US included it among the Hawaiian Islands when it annexed the archipelago in 1898. The Hawaii Statehood Act of 1959 did not include Palmyra Atoll, which is now part privately owned by the Nature Conservancy and part US Government-owned and administered as a nature preserve. The lagoons and surrounding waters within the 12-nautical-mile US territorial seas were transferred to the US Fish and Wildlife Service and were designated a National Wildlife Refuge in January 2001.

National Infrastructure

🏳 Palmyra Atoll’s critical and strategic infrastructure, sustaining output, agility and endurance

The National Infrastructure Index maps the physical assets national life runs on — power stations and grids, water systems, ports, railways and airports, data networks, payment systems and launch sites. Each asset is placed in a Strategic Infrastructure capability group, so it can be read against the ratings in the National Capability index above.

Assets are chosen for how much of the economy and state depends on them and how hard they would be to replace. Each card records what the asset is, the category it belongs to, what it does and where it is.

National Developments

🏳 Palmyra Atoll’s major milestones and key developments

The National Development Index tracks the events that move a nation's capability — policy decisions, technological milestones, economic turns and external shocks — and places each one on the record with the date it happened and what followed from it. It is the narrative counterpart to the indices: where a rating says where Palmyra Atoll stands, the index says how it arrived there.

Recent developments cover the current cycle, close enough that their consequences are still unfolding. Historical developments are the inflection points behind the present position — the decisions and events a reader needs in order to read the ratings above in context.

Historical Developments

1798Captain Edmund Fanning reported the first known sighting of Palmyra from the American sealing ship Betsy 228 years ago

Fanning, sailing to Asia aboard the Betsy, claimed to have sighted the reef later known as Palmyra after heaving to overnight on a premonition. The claim has been disputed on the grounds he may only have reached Kingman Reef, 34 miles away. It remains the earliest recorded European-American encounter with the atoll.

November 1802The ship Palmyra under Captain Cornelius Sowle was shipwrecked on the reef, giving the atoll its name 224 years ago

The vessel Palmyra struck the reef on 7 November 1802 and the atoll took the ship's name. Sowle recorded no inhabitants and no fresh water, but abundant large coconuts and fish. No evidence of pre-European settlement has been reported.

1842USS Porpoise under Charles Wilkes conducted the first scientific expedition visit to Palmyra 184 years ago

The atoll was visited as part of the United States Exploring Expedition, with live plant and animal samples collected. Wilkes recorded the island as inhabited and urged regular visits by national vessels. It was the first systematic scientific documentation of the atoll.

1859Alfred Benson and Dr Gerrit P. Judd claimed Palmyra for the United States under the Guano Islands Act 167 years ago

Both men lodged claims to the atoll under the 1856 Guano Islands Act. No guano deposits were found, so the claims were abandoned. The episode marked an early, unsuccessful American assertion of possession.

1862King Kamehameha IV of Hawaii had the atoll formally annexed to the Kingdom of Hawaii 164 years ago

On 26 February 1862 the king commissioned Captains Zenas Bent and Johnson Beswick Wilkinson to take possession, and formal annexation followed on 15 April 1862. Bent and Wilkinson became joint owners, beginning a century of private title-holding. This annexation later underpinned Palmyra's inclusion in American Hawaii.

1862–1897Bent, Wilkinson and successors passed Palmyra through successive private ownership transfers 164 years ago

Bent sold his rights to Wilkinson in December 1862; the atoll passed to Kalama Wilkinson and in 1885 was divided among four heirs. Shares moved through William Luther Wilcox, the Pacific Navigation Company (liquidated 1897), William Ansel Kinney and Fred Wundenberg. The fragmented title would generate decades of litigation.

1889Commander Nichols of HMS Cormorant claimed Palmyra for the United Kingdom, unaware of Hawaii's prior claim 137 years ago

A British naval commander asserted a claim over the atoll in ignorance of the Kingdom of Hawaii's 1862 annexation. The claim was never pursued. It illustrates the contested sovereignty of remote Pacific islets in the era.

1898The United States annexed Hawaii and Palmyra with it under the Newlands Resolution 128 years ago

The annexation of the Republic of Hawaii carried Palmyra into American possession. A subsequent Act of Congress of April 1900 made all of Hawaii, including Palmyra, an incorporated territory. This status is the legal foundation of Palmyra's unique position today.

June 1900Palmyra became part of the new U.S. Territory of Hawaii 126 years ago

On 14 June 1900 the atoll was formally incorporated into the Territory of Hawaii. It would remain administratively part of Hawaii for nearly six decades. Its incorporated status, unlike other US insular areas, meant the full Constitution applied.

1911–1912Judge Henry Ernest Cooper acquired a two-thirds interest in Palmyra and sought Torrens title 115 years ago

Wundenberg's widow sold the two-thirds undivided interest to Cooper on 12 June 1911, and in 1912 Cooper bought the Ringer daughters' rights and petitioned to register title to all of Palmyra. The Supreme Court of Hawaii held his ownership subject to rights sold to Henry Maui and Joseph Clarke. These competing native Hawaiian interests fuelled litigation into the 1990s.

February 1912The U.S. Navy sent USS West Virginia to reaffirm American sovereignty over Palmyra 114 years ago

With the Panama Canal nearing completion and Britain operating an All Red Line cable station on nearby Fanning Island, Palmyra gained strategic value. On 21 February 1912 American sovereignty was formally reaffirmed at the atoll. Palmyra land was also registered in the Hawaii Land Court that year.

1913Botanist Joseph F. Rock discovered the unique Cocos nucifera palmyrensis coconut palm 113 years ago

Rock accompanied Cooper to the atoll in July 1913 and wrote a scientific description; the unusual palms were identified by Odoardo Beccari as a variety unique to Palmyra, bearing the world's largest and most triangular coconuts. The 'mammoth coconuts' were displayed in Honolulu in 1914. The find established Palmyra's distinct botanical standing.

September 1921A U.S. naval detachment conducted the first aerial surveys of the atoll 105 years ago

A small detachment was sent as part of a national effort to document outlying American territory, taking aerial photographs over two days of favourable weather. The USS Eagle Boat 40 transported aircraft and equipment. At the time only three Americans lived on the atoll.

August 1922Henry Ernest Cooper sold Palmyra to the Fullard-Leo family, who founded the Palmyra Copra Company 104 years ago

On 19 August 1922 Cooper sold his interest, excepting two minor islets, to Leslie and Ellen Fullard-Leo for $15,000. They established a copra business harvesting the atoll's coconuts. The Fullard-Leos would hold the atoll for nearly eighty years and successfully defend their title against the federal government.

1937The Fullard-Leo family and the U.S. Navy began negotiations that led to a federal quiet title suit over Palmyra 89 years ago

The family sought to lease the atoll to the Navy, prompting the government to sue, claiming Palmyra had never been privately owned. The case ran through the Second World War while the Navy occupied and built on the atoll. It reached the U.S. Supreme Court.

1938–1939The U.S. Navy began construction of an airfield at Palmyra 88 years ago

The Navy selected the site for an airfield in 1938 despite Interior Secretary Harold Ickes's plea to Roosevelt to preserve the atoll's scientific and scenic value. The first construction group sailed from Honolulu on 14 November 1939. A 2,000-yard unpaved airstrip was built on Cooper Island.

1939President Roosevelt issued Executive Order 8616 placing Palmyra under Navy control 87 years ago

Following a 1939 Attorney General determination that Palmyra was US public land and the Fullard-Leo claim invalid, Roosevelt placed the island under the jurisdiction of the Secretary of the Navy. This was the first official assertion of naval jurisdiction over the atoll. Claims that a 1934 order had done so are unsupported.

1939–1945Wartime construction reduced the atoll's islets from 52 to 25 87 years ago

Extensive military development consolidated and reshaped the land during the Navy's occupation. The alterations permanently changed the atoll's physical geography and hydrology. Much of the base was demolished after the war, with debris burned, dumped in the lagoon or left as unexploded ordnance.

1941The U.S. government blasted a ship channel and reshaped the atoll's landforms 85 years ago

Dredging opened a channel from the open sea into the previously non-navigable West Lagoon, reached on 15 May 1941. Islands were joined by causeways, new islands built, and runways laid on dredged coral spoil. The works blocked water flow and are believed to have severely damaged lagoon ecology.

Recent Developments

September 2024Conservation managers introduced the Guam kingfisher to Palmyra 2 years ago

The bird, extinct in the wild and existing only in captivity since the 1980s, was released on the atoll. The introduction made Palmyra a refuge for a species with no remaining native habitat. It marked a significant step in the atoll's role in global biodiversity conservation.

2019TNC, Island Conservation and the Fish and Wildlife Service began removing coconut palms to restore native rainforest 7 years ago

The partnership targeted dominant Cocos nucifera palms, the legacy of former copra plantations and military activity. By December 2019 half a million coconut sprouts had been removed. The ecosystem's response is being monitored closely.

2011–2012Fish and Wildlife Service, TNC and Island Conservation eradicated the atoll's invasive rats 15 years ago

A programme begun in 2011 targeted non-native rats that had arrived during the Second World War, at one point numbering as many as 30,000. They ate seabird eggs and destroyed seedlings of one of the largest remaining Pacific stands of Pisonia grandis. The rats were eliminated in 2012.

January 2009President George W. Bush established the Pacific Remote Islands Marine National Monument 17 years ago

The proclamation of 6 January 2009 grouped Palmyra with Baker, Howland, Jarvis, Johnston and Kingman Reef, extending 50 nautical miles offshore. It is managed jointly by the Fish and Wildlife Service and NOAA. The grouping was renamed the Pacific Islands Heritage Marine National Monument in 2025.

November 2005The Nature Conservancy established a research station on Palmyra 21 years ago

The station was set up to study global warming, coral reefs, invasive species and other environmental concerns. It built on earlier work such as the 2003 study of fossilised coral used to reconstruct 1,000 years of El Niño behaviour. Palmyra became a significant Pacific scientific research platform.

2003The Nature Conservancy conveyed 416 acres of emergent land to the United States for the refuge 23 years ago

In March 2003 TNC transferred the land to federal ownership, adding a further 28 acres in 2005. TNC and Cooper descendants retained remaining private tracts. The conveyance consolidated federal conservation management of the atoll.

18 January 2001The United States designated Palmyra's lagoons and surrounding waters a National Wildlife Refuge 25 years ago

Secretary of the Interior Bruce Babbitt's Order No. 3224 of 18 January 2001 designated Palmyra Atoll National Wildlife Refuge, covering the tidal lands, submerged lands, lagoons and waters within the 12-nautical-mile US territorial sea, which were transferred to the US Fish and Wildlife Service. Accompanying regulations closed the refuge to commercial fishing while permitting limited recreational fishing; displaced commercial licensees later sued unsuccessfully under the Takings Clause, losing on appeal in April 2009. The atoll is today part privately owned by the Nature Conservancy and part US Government-owned, administered as a nature preserve.

December 2000The Nature Conservancy bought most of Palmyra Atoll for US$30 million 26 years ago

The Conservancy purchased the majority of the atoll from the three Fullard-Leo brothers for coral reef conservation and research, leaving only the Home and possibly Sand islets in other hands. The sale ended nearly eight decades of family ownership. It transformed Palmyra into a conservation and scientific research site.

1997–1999Rachel Lahela Kekoa Bolt and descendants filed lawsuits challenging American sovereignty over Palmyra and Hawaii 29 years ago

Heirs of Henry Maui claimed inherited interests in the atoll and contested the legality of the Newlands Resolution annexing Hawaii. They also intervened in a federal salvage claim over a supposed treasure ship at Palmyra. The cases were dismissed on procedural grounds before trial.

1980sPalmyra's owners closed the atoll to visitors after an injury lawsuit 46 years ago

In 1980 two members of a visiting amateur radio DXpedition were injured badly enough to require airlift to Honolulu, and the injured surgeon sued the owners. The atoll was closed to visitors for most of the 1980s while cleanup was undertaken. Radio expeditions had been its most consistent visitors since the 1940s.

1979–1982The U.S. government explored and then abandoned storing nuclear waste at Palmyra 47 years ago

From early 1979 officials considered siting spent nuclear fuel storage on remote Pacific islands including Palmyra, with a formal proposal written by 1982. Critics warned of the devastating consequences of a leak. The idea was abandoned soon after and no facilities were built.

1974Duane Walker and Stephanie Stearns committed the Sea Wind murders on Palmyra 52 years ago

A wealthy San Diego couple, Malcolm and Eleanor Graham, disappeared at the atoll; the pair were arrested in Honolulu after returning aboard the stolen yacht Sea Wind and convicted only of theft. Eleanor Graham's remains were found in a lagoon chest six years later; Walker was convicted of murder in 1985 and Stearns acquitted in 1986. The case produced the book And the Sea Will Tell and a CBS miniseries, making the atoll internationally notorious.

1962The Department of Defense used Palmyra as an observation site for high-altitude nuclear tests 64 years ago

About forty people carried out observations of nuclear weapons tests conducted high above Johnston Atoll, supported by around ten more. It was the atoll's principal Cold War military use. No permanent installation resulted.

1961The President issued Executive Order 10967 assigning administration to the Interior Department 65 years ago

Effective 10 October 1961, the order made the Department of the Interior responsible for all executive, legislative and judicial authority of Palmyra's civil administration. This filled the governance vacuum left after Hawaiian statehood. The Air Force ceased maintaining the main airfield the same year.

1959The United States Congress separated Palmyra from Hawaii upon statehood 67 years ago

When Hawaii was admitted as a state, Palmyra was explicitly excluded and remained a federal incorporated territory. It has since been the only incorporated US territory. No Act of Congress since has specified how it is to be governed.

1947The U.S. Supreme Court decided United States v. Fullard-Leo, upholding private title 79 years ago

The Court quieted good land title against the federal government in favour of the Fullard-Leos and Cooper heirs. The base was consequently returned to private ownership in 1947. The ruling preserved private landholding on an incorporated US territory.

January 1942The U.S. Army Air Forces stationed B-17 bombers at the Palmyra airbase 84 years ago

On 16 January 1942 six Boeing B-17 Flying Fortress bombers arrived from Hawaii. Marine Corps VMF-211 pilots also used the airfield. Palmyra served through the war as a refuelling and training station rather than a combat front.

December 1941Imperial Japanese Navy submarine I-75 shelled the naval air station at Palmyra 85 years ago

On 24 December 1941 the submarine fired twelve 120mm rounds at the atoll's radio station, hitting the dredge Sacramento with one shell. A 5-inch coastal battery returned fire and forced I-75 to submerge and withdraw. It was the atoll's only enemy attack of the war, causing no significant damage.

February 1941President Roosevelt established the Palmyra Island Naval Defensive Sea Area 85 years ago

Executive Order 8682 of 14 February 1941 created naval defensive sea areas in the central Pacific, covering Palmyra's territorial waters out to three miles, plus a Naval Airspace Reservation. Only authorised US government ships and aircraft could enter. The Navy formally took the atoll as Palmyra Island Naval Air Station on 15 August 1941.
