5 - Shemya Island

Shemya or Simiya (Aleut: Samiyax̂[1]) is a small island in the Semichi Islands group of the Near Islands chain in the Aleutian Islands archipelago southwest of Alaska, at 52°43′27″N 174°07′08″E / 52.72417°N 174.11889°E / 52.72417; 174.11889. It has a land area of 5.903 sq mi (15.29 km2), and is about 1,200 miles (1,900 km) southwest of Anchorage, Alaska. It is 2.73 miles (4.39 km) wide and 4.32 miles (6.95 km) long.

History

[edit]
Shemya Island north shore

The Russian vessel Saint Peter and Paul was wrecked at Shemya in 1762. Most of the crew survived.

In 1943, a United States Air Force radar surveillance, weather station, aircraft refueling station, and a 10,000-foot-long (3,000 m) runway opened on Shemya and are still in operation. At its peak in the 1960s, the station, originally Shemya Air Force Base or Shemya Station, had 1,500 workers. In 1956, Northwest Airlines leased Shemya Island from the U.S. government to use as a refueling station on their North Pacific route. According to Northwest's website, that made them "the first airline to operate its own airport."[2] Northwest was operating Lockheed Constellation L-1049G model propliners on its "Orient Express" service between the U.S. and Asia in 1956.[3]

During the height of the Cold War, the United States Air Force airborne intelligence platforms "Cobra Ball", "Rivet Amber," and "Rivet Ball" flew intercontinental ballistic missile tracking flights from this island near the Soviet Union, especially the Kamchatka Peninsula. Observations from Shemya were normally the first radar reports of new Soviet satellite launches from Tyuratam (Baikonur) in the early days of satellite tracking; see Project Space Track.

In 1993, the station was renamed the Eareckson Air Station to honor USAF Colonel William O. Eareckson, who had commanded bomber operations during the Aleutian Campaign of World War II.

The station still operates as a radar station and aircraft refueling station with a staff of about 180 people. The 2000 census reported an official resident population of 27 persons on the island.

One of the most recognizable features of the island is the COBRA DANE radar system. This radar was built in 1976 and brought on-line in 1977 for the primary mission of intelligence gathering in support of verification of the Strategic Arms Limitation Talks (SALT) II agreement.

Shemya was an important outpost during the Cold War;[4] as part of Project Bluegrass, the White Alice Communications System provided a vital tropospheric scatter communications link to the mainland during the early-1960s to late-1970s. Its two 120-foot (37 m) parabolic reflectors and 50 kW transmitter output bridged the nearly 400 miles (640 km) gap to Adak, Alaska.

Former airline service

[edit]

Reeve Aleutian Airways (RAA) operated scheduled passenger service into Shemya for many years. During the 1970s and 1980s, Reeve operated nonstop flights to Anchorage (ANC) with Lockheed L-188 Electra turboprop aircraft.[8] By 1989, the airline was operating nonstop jet service to Anchorage with Boeing 727-100 combi aircraft which were capable of transporting passengers and freight on the main deck of the aircraft.[9] Reeve's 727 service from Anchorage continued during the 1990s as did 727 flights from Adak Island, AK and Cold Bay, AK.[10] Reeve Aleutian ceased all flight operations in 2000.

Climate

[edit]

The weather on Shemya is very drastic, though the temperatures vary only between single digits and the mid-fifties. The climate is perhaps the most equatorward low-altitude occurrence of a polar climate (ET) in the world, though it is extremely close to a subpolar oceanic climate (Cfc), or a subarctic climate if the 0 degree Celsius isotherm is used. The island weather is most likely to be cloudy with a mist. The wind ranges from 30 to 40 miles per hour (48 to 64 km/h).

The Japanese current in the Pacific to the south of the island regulates the temperature and gives it the pronounced temperature lag. August and September are the warmest months. The island's record low occurred in April. Despite it being a tundra climate, it is spared the vicious cold of places like Utqiagvik, Alaska, where temperatures in winter can rival those of interior Alaska in winter.

View on Grokipedia
from Grokipedia
Shemya Island is a remote, 5.9-square-mile (15 km²) landmass in the Semichi group of the western Aleutian Islands, Alaska, situated approximately 1,500 miles (2,400 km) southwest of Anchorage and near the international date line, closer to Russia than to mainland North America. The island's primary significance stems from Eareckson Air Station, a United States Air Force installation constructed in May 1943 during World War II as a forward operating base for bombers and fighters to counter Japanese occupation of nearby Attu and Kiska. Renamed in 1993 to honor Colonel William O. Eareckson, who led Aleutian air operations, the station transitioned to caretaker status in 1995 but maintains critical roles in ballistic missile early warning via the COBRA DANE L-band phased-array radar, space surveillance, and emergency aircraft refueling in the North Pacific. Supported by about 160 contractor personnel, Shemya's strategic position has sustained its value for intelligence collection on Soviet and Russian missile tests since the Cold War, underscoring U.S. deterrence capabilities amid ongoing regional tensions.

Geography and Environment

Location and Physical Features

Shemya Island lies in the Semichi Islands group of the chain, at the extreme western end of the archipelago in southwestern . It is positioned approximately 1,500 miles southwest of Anchorage, with central coordinates around 52°42′ N and 174°07′ E . The island's remote position places it near the boundary between the to the north and the North to the south, roughly 100 miles east of Russian territory across the . The island measures approximately 4 miles long by 2 miles wide, covering a land area of about 6 square miles. Its is predominantly low and flat, with elevations generally below 100 feet above and a maximum height of 144 feet at North Head on the northern shore. The western two-thirds consists of interbedded Tertiary-age sedimentary and volcanic rocks, while the eastern portion features unconsolidated deposits, including freshwater lakes and boggy terrain. No active volcanoes are present on the island itself, distinguishing it from more volcanically active parts of the Aleutian chain. Notable physical features include Cable Bowl, a large, bowl-shaped gravel depression on the north shore used historically for submarine cable landings, and rugged coastal cliffs interspersed with beaches, such as Fox Beach, a tiny (0.1-mile-long) rocky beach on the southeastern coast. The surrounding waters are part of the seismically active Aleutian subduction zone, contributing to occasional tsunami risks, with modeled maximum runup heights reaching 40 meters on the northern side and 58 meters on the southern side under extreme scenarios.

Climate

Shemya Island's climate is classified as subarctic maritime (Köppen Dfc), featuring mild but consistently cool temperatures, high humidity, frequent overcast skies, and pervasive wind influenced by its remote North Pacific location. Annual average temperatures hover around 38°F (3°C), with extremes rarely exceeding 60°F (16°C) in summer or dropping below 10°F (-12°C) in winter. Precipitation occurs on over 200 days per year, primarily as fine drizzle or rain, totaling approximately 30 inches (76 cm) annually, supplemented by about 50 inches (127 cm) of snowfall. Winter months (December to February) bring average highs of 33–35°F (1–2°C) and lows near 28°F (-2°C), with recording a mean maximum of 33.8°F and minimum of 28.4°F, alongside 2–2.5 inches (5–6 cm) of liquid-equivalent monthly. Summer ( to ) sees modest warming, with highs averaging 50°F (10°C) and lows around 42°F (6°C), though and low ceilings often obscure . Snowfall peaks in winter, averaging 11–16 inches (28–41 cm) per month from December to February. Persistent strong winds define the region's harshness, with annual averages of 20–25 mph (32–40 km/h) and frequent gusts exceeding 50 mph (80 km/h); stands as the windiest month at 32 mph (51 km/h) average. Storms can produce gusts over 80 mph (129 km/h), as observed during intense cyclones. is prevalent year-round but intensifies from through early due to cool southwesterly airflow over warmer ocean waters, contributing to reduced visibility and operational challenges at .

Ecology and Environmental Impacts

Shemya Island's ecology is characterized by maritime and alpine tundra vegetation, consisting primarily of mosses, lichens, and over 200 species of vascular plants, some of which are Asian in origin. The island lacks trees and supports low-growing herbaceous plants adapted to the harsh subarctic conditions, with coastal zones providing nutrient-rich habitats influenced by marine inputs. Wildlife on Shemya is dominated by avian , with over 200 birds recorded, including large populations of such as short-tailed shearwaters, black-legged kittiwakes, tufted puffins, and migratory waterfowl and songbirds like lapland longspurs. colonies have historically shaped local vegetation through ornithogenic processes, depositing that enriches soil nutrients, as evidenced by stable indicating active colonies from approximately 4,600 to 2,400 calibrated years . Marine mammals, including seals and sea lions, utilize coastal areas for foraging and haul-outs year-round. Arctic foxes inhabit the island, preying on birds and eggs, while the absence of invasive rats helps preserve native , aligning with broader Aleutian conservation efforts. Military activities at have caused significant environmental contamination, including per- and polyfluoroalkyl substances (PFAS) in from aqueous film-forming foam (AFFF) used in firefighting training, alongside (TCE), hydrocarbons, and from and operations. The island's remains contaminated, with sources including hangar operations and spills not fully remediated. In June 2022, the U.S. Agency fined the $10,000 for mismanaging hazardous wastes, such as tons of , oil, paints, and stored improperly without required containment. These pollutants pose risks to soils, coastal habitats, and through in food chains, though comprehensive studies on direct ecological effects remain limited due to restricted access. Shemya lies within the Maritime , but military withdrawal overrides full refuge protections, complicating habitat management.

History

Pre-20th Century and World War II Era

Shemya Island, known to the Unangan (Aleut) people as Samiyax̂, features archaeological evidence of human occupation dating back several millennia. Excavations at multiple sites have yielded 752 artifacts, including stone tools, bone implements, and deposits with remains, indicating a small resident population sustained by and hunting. One site along the southwestern dates to approximately 3500–3000 years , reflecting persistent low-density settlement adapted to the harsh environment. Petroglyphs and portable , such as a seal-shaped stone, further attest to cultural practices, with the latter likely carved on-site and representing one of few such examples from the Aleutians. In early historic periods following Russian contact in the 18th century, Shemya served as a center for a local Aleut political unit, though permanent populations remained sparse due to the island's isolation and limited resources. Aleuts conducted seasonal harvesting of seabirds and marine mammals, but by the late 19th century, visits were infrequent as populations shifted eastward amid fur trade disruptions and disease impacts from European incursions. During , Shemya gained strategic prominence after Japanese forces occupied nearby in June 1942, prompting U.S. concerns over further advances toward . To counter this threat and establish a forward base for operations against Japanese-held positions, U.S. Army troops from the 4th Infantry Regiment landed unopposed on May 29, 1943, securing the island 35 miles east of . Construction of Shemya Army Airfield commenced immediately thereafter, with engineers rapidly building a 10,000-foot using local gravel and volcanic ash to support heavy bombers. The airfield opened in , enabling air raids on Japanese forces at and , as well as reconnaissance and bombing missions toward the . Defensive fortifications, including gun emplacements and bunkers, were erected to protect against potential amphibious assault, prioritizing airfield security amid the active Aleutian theater. By late 1943, after the recapture of Attu and evacuation of , Shemya transitioned to a staging point for long-range patrols, though harsh weather and logistical challenges limited operations. The base's development, completed by December 1945, underscored its role in denying a foothold in the western Aleutians and supporting superiority in the North Pacific.

Cold War Period

Following , Shemya Air Force Base was largely inactivated, with operations ceasing after the due to reduced military needs. In response to escalating tensions, the base was reactivated on July 15, 1958, with the activation of the 5040th Air Base Squadron to provide logistical support for strategic intelligence activities conducted by both the U.S. Air Force and Army. The squadron was redesignated the 5073rd Air Base Squadron in October 1959, overseeing airfield operations and serving as a refueling point along the Great Circle Route for military aircraft, including B-52 bombers and KC-135 tankers during missions like in the 1960s. By 1962, the 5073rd Air Base Group assumed control, maintaining a focus on surveillance and communications amid growing Soviet threats in the North Pacific. Shemya's strategic position enabled it to host early warning radar systems, with the and becoming operational in May 1960 to monitor potential aerial incursions and support gathering on Soviet activities. These systems were complemented by operations from the Security Service and Security Agency detachments in the and , including electronic intelligence (ELINT) collection and spy flights using RC-135 Cobra Ball aircraft starting in the late to detect and analyze Soviet missile launches. Communications infrastructure was bolstered in 1961 through Project Bluegrass, establishing the White Alice system with 120-foot parabolic reflectors linking Shemya to Adak over 393 miles, facilitating real-time data relay to continental U.S. command centers until its decommissioning in the 1980s. A major escalation occurred with the construction of the phased-array radar facility from 1973 to 1977, costing $68 million and featuring the AN/FPS-85 array with 34,700 radiating elements capable of tracking objects over a 2,000-mile, 120-degree corridor toward Soviet test sites in Kamchatka and Tyuratam. Operational from July 1977 after replacing earlier radars, integrated into the U.S. Space Detection and Tracking System (SPADATS) and provided critical data on Soviet (ICBM) tests, re-entry vehicles, and space launches, contributing to ballistic missile early warning. The base hosted its first post-World War II fighter deployment in November 1977 with F-4E Phantoms, and on April 28, 1982, F-15 Eagles from the facility intercepted Soviet Tu-95 Bear bombers, underscoring Shemya's role in air defense intercepts. Personnel peaked under oversight from Eielson AFB's 5010th Group around 1975 before declining to approximately 600 by 1980, reflecting sustained but specialized operations through the Cold War's end.

Post-Cold War and Contemporary Developments

Following the end of the , operations at Shemya significantly downsized in the early , with the U.S. reducing personnel and transitioning the installation to a caretaker role. On April 6, 1993, Shemya Station was renamed in honor of Colonel William O. Eareckson, a squadron commander who led operations in the Aleutians. The facility ceased operations as an active station on July 1, 1994, but remained under U.S. ownership and was managed by the 611th with contractor support, eliminating permanent military assignments while retaining approximately 140 base operating support contractors by the late 2000s. By 1995, it had fully shifted to caretaker status, focusing on maintenance of key infrastructure like the 10,000-foot runway and support for transient missions rather than large-scale permanent basing. The primary enduring function became hosting the AN/FPS-108 , an L-band phased-array operational since 1977, which provides early warning, space surveillance, and tracking data integrated into U.S. systems. Sustainment efforts continued through the and , including contractor-managed operations with a small on-site team, emphasizing reliability amid reduced overall activity. The airfield supported occasional refueling for transpacific flights and emergency diversions, but saw limited military deployments until heightened tensions prompted renewed utilization. In contemporary developments, Eareckson has regained strategic prominence due to its proximity to —approximately 280 miles from the nearest Russian territory—and role in monitoring threats. exercises intensified, including U.S. Army Night Stalker operations in August 2023 to rehearse defense of the island's and airfield assets. Deployments resumed in 2018 with U.S. Army units, followed by a major exercise in September 2024 involving airborne infantry from Alaska's , plus troops from and Washington, alongside High Mobility Artillery Rocket Systems (HIMARS) relocated for Pacific theater simulations—the first such rotation since 2018. sustainment advanced with a $62 million U.S. contract awarded in April 2025 for life-cycle support, alongside plans announced in August 2025 for a comprehensive modernization estimated at nearly $1 billion to upgrade the 49-year-old system for ongoing threat detection.

Military Installations and Operations

Eareckson Air Station Overview

Eareckson Air Station is a remote United States Air Force facility situated on Shemya Island, at the western tip of the Aleutian Islands chain in Alaska, approximately 1,500 miles southwest of Anchorage. Originally constructed by the U.S. Army in 1943 to facilitate offensive operations against Japanese-held positions on nearby islands like Attu and Kiska during World War II, the installation featured an airfield that supported B-24 Liberator bombers and other aircraft in the Aleutian Campaign. The station was redesignated on May 6, 1993, in tribute to Colonel William O. Eareckson, a pioneering aviator who commanded the 28th Bombardment Group in the Aleutians and advocated for forward basing strategies during the war. It ceased operations as an active base on July 1, 1994, transitioning to caretaker status under the ownership of the U.S. and operational control of . Managed by the 611th Air Support Squadron out of Elmendorf-Richardson, the site maintains a minimal permanent staff to sustain essential functions amid extreme weather and logistical isolation. Primarily serving as a surveillance outpost, Eareckson hosts the COBRA DANE radar system, a large phased-array installation operational since that tracks foreign tests and space launches over distances exceeding 2,000 miles, feeding data to U.S. and intelligence networks. The airfield, designated ICAO code PASY, continues to function as a critical refueling and emergency diversion point for and civilian along trans-Pacific routes, with a 10,000-foot capable of handling heavy bombers and transports despite frequent and high winds.

Key Facilities and Technologies

The (AN/FPS-108) radar stands as the central technological asset at , functioning as a ground-based, L-band phased-array radar system operated by the . This (PESA) installation, with a single 95-foot-diameter face rising approximately 120 feet high, tracks foreign launches and collects metric and signature data on events up to 2,000 miles distant. Operational since 1977 following activation in 1976, it provides midcourse phase coverage for defense and supports surveillance within the U.S. Command area. Sustainment and modernization initiatives have sustained its capabilities amid aging challenges. In , Diversified Technologies delivered a transmitter group replacement to enhance reliability and . Ongoing upgrades target the backend systems, signal processors, and processes to integrate with contemporary architectures. In April 2025, V2X secured a $62 million contract from the to maintain operational readiness, including and tailored to the remote Alaskan environment. Supporting includes dedicated power generation, cooling systems, and maintenance facilities essential for continuous operations, though detailed public specifications remain classified or limited due to strategic sensitivities. These elements enable year-round functionality despite Shemya's , underscoring the installation's role in persistent surveillance over the North Pacific and regions.

Strategic Importance and Recent Deployments

Shemya Island's strategic value stems from its position in the western Aleutian chain, approximately 280 miles from Russian territory, enabling surveillance of North Pacific and approaches. hosts systems and supports missions, facilitating monitoring of adversarial activities near U.S. and maritime boundaries. This proximity to Russia's Pacific submarine fleet and fighter squadrons on the underscores its role in deterring competition, particularly amid expanded Russian and Chinese operations in the . The station serves as a forward operating location for projecting U.S. air power, with capabilities for refueling, collection, and rapid response to incursions. Its remoteness enhances its utility for low-observable operations while complicating adversary targeting, though logistical challenges like limit sustained large-scale basing. In the context of militarization, Shemya bolsters U.S. domain awareness against hybrid threats from and , including joint naval patrols observed annually since 2022. Recent deployments highlight heightened operational tempo. In September 2024, the U.S. Army dispatched approximately 130 soldiers from the 1st Stryker Brigade Combat Team, 25th Infantry Division—known as the Arctic Angels—along with elements from Hawaii and Washington units, to Shemya for a force projection exercise. This marked the first such Army presence since 2018 and included an M142 High Mobility Artillery Rocket System (HIMARS), coordinated with Air Force assets to transport personnel and equipment amid Russian aircraft and vessel probes near Alaska. The move responded to eight Russian military planes and four vessels, including submarines, approaching U.S. exclusive economic zones in the preceding week. No major deployments were publicly reported in 2025, though broader exercises like Northern Edge emphasized Alaska's role in joint training without specifying Shemya activity.

Communications are handled via CTAF 127.2 MHz and Anchorage ARTCC frequencies 119.1/339.8 MHz.

Support Facilities and Access Challenges

Eareckson Air Station maintains limited support facilities to sustain its remote radar and airfield operations, including barracks and dormitories for approximately 200 military and contractor personnel, along with basic amenities such as a gymnasium and areas. infrastructure features a bulk storage system and a repaired in Alcan Harbor, capable of handling over-the-shore deliveries of millions of gallons annually via contracted barges, though damage from storms necessitates frequent interventions. Vehicle maintenance is supported by Building 525, a dedicated complex housing repair equipment, alongside a gas station and , oil, and lubricants (POL) parking areas. Utilities rely on on-island generation for power and systems, with handled through limited treatment plants adapted to the island's harsh conditions. Access to Shemya Island is severely constrained by its position at the western extremity of the Aleutian chain, approximately 1,500 southwest of Anchorage, requiring either C-130 or commercial flights taking about four hours or seasonal transport from spanning up to one month. , including frequent , high winds exceeding 100 knots, and winter storms, limits air operations to much of the year and confines deliveries to a brief summer window, often delayed by turbulent conditions that have destroyed docking infrastructure multiple times. Military restrictions further bar civilian access without special authorization from the 611th Air Support Squadron, due to the site's classified functions and environmental sensitivities. Logistical support demands extensive coordination for all resupply, with no connecting roads or ports beyond the airfield and fuel pier, amplifying costs and delays for maintenance or personnel rotations.

Civilian and Commercial Aspects

Flight Diversions and Emergency Use

Eareckson Air Station's airfield on Shemya Island serves as a designated emergency diversion site for civilian trans-Pacific flights, equipped with a 10,000-foot runway capable of handling wide-body jetliners such as Boeing 767s and 777s when mechanical issues or other emergencies arise over the remote North Pacific, where suitable alternates are scarce. The facility's strategic position, approximately 1,450 miles southwest of Anchorage, positions it as one of the few viable options for extended-operations (ETOPS) routes between Asia and North America, supporting aviation safety protocols despite its primary military function. Notable diversions include Flight 128 on December 24, 2018, which en route from to with 194 passengers aboard diverted due to a potential engine issue; the 767-300ER landed safely, and passengers received support from base contractors before continuing onward. On July 29, 2015, Flight 884 from to , a 777-300ER, made a precautionary around 3:30 a.m. local time after crew detected smoke on board; all passengers and crew deplaned without injury, and the aircraft departed later that day following inspections. Another incident occurred on July 12, 2010, when an from Dallas-Fort Worth diverted due to a fire warning light malfunction, landing safely at the station. These events underscore the airfield's logistical challenges for civilian operations, including limited amenities and coordination with U.S. personnel for refueling, , and passenger handling, all conducted under strict military oversight and only with prior authorization for non-scheduled use. While diversions are infrequent, the station's readiness has prevented potential catastrophes in an expanse with few alternatives, such as or .

Historical Airline Operations

Northwest Airlines initiated support operations at Shemya Island in 1950, deploying radio operators to facilitate military activities from the airfield. On January 1, 1956, the airline leased the island from the U.S. government specifically as a refueling stop on its North Pacific route, enabling the first nonstop commercial flights between the U.S. mainland and via paths over the polar region. This arrangement positioned Shemya as a critical logistical node for trans-Pacific civilian during the mid-20th century, with Northwest maintaining facilities including fuel storage and ground support amid the island's primary military role. Reeve Aleutian Airways operated scheduled passenger services to Shemya for several decades, including nonstop flights from Anchorage during the and , serving civilian contractors, researchers, and occasional personnel connected to base activities. These routes utilized the airfield's long , which supported larger propeller and early despite the remote location and harsh weather, though operations remained limited compared to traffic. By the late , such commercial passenger flights ceased, with the airfield reverting primarily to and diversion use.
