Nike Missile Site S-92 IFC, Kingston Washington

Nike Missile Site S-92 was the Kingston, Washington Nike missile battery in the Seattle Defense Area. It was a former U.S. Army air-defense missile installation, not an active military installation today. The site began as a Nike Ajax battery and later became one of the Seattle-area batteries converted for Nike Hercules. It is best understood as the west-side Hercules battery of the Seattle ring, positioned in north Kitsap County to cover the western and northwestern approaches to Puget Sound, the naval and industrial areas around Seattle and Bremerton, and the broader transportation and military infrastructure of the central Puget Sound region.

S-92 is sometimes confused in secondary lists with Bainbridge Island, but that is not the best identification. The Kingston site was S-92. The Bainbridge/Winslow Nike site was S-82.

The site is closed. The full operational period is best stated as 1956 to March 1974 when the Ajax operating history is included. The federal technical inventory lists S-92 as active from 1958 to March 1974, which appears to emphasize the later Hercules-era configuration rather than the original Ajax start.

Units That Served at S-92

The available site notes identify the following operating units for S-92:

• C Battery, 513th Antiaircraft Artillery / Artillery: approximately 1956 to September 1958.
• C Battery, 4th Missile Battalion, 4th Artillery: September 1958 to September 1972.
• C Battery, 1st Missile Battalion, 4th Artillery: September 1972 to March 1974.

At the time of the final Seattle Defense Area Nike shutdown, the three surviving Seattle-area batteries were S-13 Redmond, S-61 Vashon Island, and S-92 Kingston. The first two were Washington Army National Guard batteries in the late period; S-92 is identified in Mark Morgan's notes as C/1/4th at the time of shutdown.

Strategic Setting and Purpose

The Seattle Defense Area existed because Puget Sound was a major Cold War target set. The region contained Boeing aircraft production and aerospace facilities, the Seattle industrial and port complex, naval facilities in the greater Puget Sound area, the Bremerton naval shipyard region, McChord Air Force Base, Fort Lawton, regional transportation corridors, and other infrastructure that would have mattered in a Soviet long-range bomber attack scenario. Nike sites were arranged in a ring so that incoming aircraft could be detected, tracked, assigned, and engaged before reaching the defended urban, industrial, and military core.

S-92's Kingston location gave the Seattle ring a west-side and northwest-side battery on the Kitsap Peninsula. That mattered because Seattle's defended area was not simply downtown Seattle. The Puget Sound defense problem included the water approaches, the Kitsap side of the sound, naval facilities and shipping corridors, and bomber approach routes that could come from the Pacific and Strait of Juan de Fuca directions. S-92 complemented the other west-side Puget Sound Nike sites, including S-61 on Vashon Island, S-62 at Olalla, S-81 at Poulsbo, and S-82 at Winslow/Bainbridge Island. Of those west-side sites, S-92 was the one retained into the Hercules era.

The Seattle Defense Area initially relied on a larger set of Nike Ajax batteries. Ajax was a radar-guided, liquid-fuel surface-to-air missile intended to intercept high-altitude bomber targets with conventional high-explosive warheads. By the late 1950s, Nike Hercules made it possible to defend the same airspace with fewer sites. Hercules had greater range, used solid fuel, and was nuclear-capable, allowing one missile to destroy or disrupt bomber formations rather than a single aircraft. In Washington, most Nike Ajax sites closed between 1960 and 1964, while the Hercules-converted sites remained in service longer. In the Seattle area, the long-lived Hercules sites were S-13/S-14 Redmond, S-61 Vashon Island, and S-92 Kingston.

Site Layout and Facilities

Like other Nike batteries, S-92 was divided into two main functional areas separated by distance but linked operationally.

The Integrated Fire Control, or IFC/control area, was the radar and command portion of the battery. At S-92 this area was north of Kingston on Ohio Avenue. The IFC contained the radar equipment and control facilities needed to acquire a target, track the target, track the missile, compute the engagement, and guide the missile toward the target. Mark Morgan's 1989 field notes described the S-92 control site as intact, including radar platforms, and associated with AGC Laborers Training. Later notes recorded substantial redevelopment at the control site, with radar towers removed, only a few smaller Army-era structures surviving, and large brick/tile office and classroom buildings added for laborers' training use.

The launch area was west of Kingston at 8998 West Kingston Road. It contained the missile magazines, launchers, assembly/checkout or support buildings, access roads, security fencing, and other battery support features. The federal inventory identifies the launch site as intact and associated with the North Kitsap County School District and Spectrum Alternative Center. Mark Morgan's notes describe the launch site as a two-magazine, eight-launcher Hercules-capable installation. His later field note recorded that the gate-area Army structures and assembly building remained in good condition and in use, but that the two magazines had been buried beneath a large glass-and-steel school bus maintenance facility.

The federal missile-type listing for S-92 is Nike 2B/12H,20A/8L-U. In plain-language terms, that indicates a site with two B-type missile magazines, Ajax/Hercules transition capacity, and universal launch equipment associated with the Hercules-era configuration. S-92 was equipped with HIPAR, or High-Power Acquisition Radar, which gave the Hercules battery improved long-range acquisition capability.

Operational History

Nike Site S-92 emerged from the mid-1950s expansion of the Seattle Defense Area. The Seattle area received its first Nike Ajax missiles in the mid-1950s, with permanent batteries forming a defensive ring around the Puget Sound region. S-92 filled a key geographic role in that ring by covering the Kingston/north Kitsap sector.

As an Ajax battery, S-92 would have operated with a normal separation between radar/control and launch functions. The IFC crew detected and tracked targets, while the launch area crew prepared missiles in underground magazines and raised them to launchers on command. In an actual engagement, the fire-control system would have guided the missile by command guidance, tracking both target and missile and steering the missile toward intercept.

The transition to Hercules changed the significance of S-92. The Army did not convert every Seattle-area Ajax battery. Instead, it retained only selected sites whose location and physical layout could support the longer-range Hercules system. S-92 became the western Hercules battery of the Seattle Defense Area. Appendix D of the Nike Hercules history places S-92 in the early converted-site sequence and gives its Hercules operational date as May 19, 1959.

Once converted, S-92 remained part of the reduced but more capable Seattle Defense Area. Fort Lawton served as the Seattle Army Air-Defense Command Post. The defense area initially used the AN/FSG-1 Missile Master system and later the AN/GSG-5 BIRDIE system to coordinate the surviving batteries. The regional air-defense network was also tied into the Air Force/NORAD radar and SAGE environment, allowing targets to be detected and assigned across a wider air-defense system.

The battery remained in service until March 1974. By then, U.S. continental air defense had changed fundamentally. The Soviet long-range bomber threat that had justified dense rings of surface-to-air missile sites in the 1950s had been overshadowed by intercontinental ballistic missiles and submarine-launched ballistic missiles. Most U.S. Nike sites had already closed. The final Seattle-area Hercules batteries were part of the last generation of ARADCOM Nike operations before the system was shut down.

Current Status and Reuse

The former IFC/control site on Ohio Avenue is reused as the Northwest Laborers-Employers Training Trust Fund / Northwest Laborers Training campus. Current training-center sources list the Kingston main campus at 27055 Ohio Avenue NE, Kingston, Washington.

The former launch site at 8998 West Kingston Road is associated with the North Kitsap School District. The launch property has been used by Spectrum Community School and the district's bus maintenance/transportation functions. The Washington Department of Health fact sheet describes the launch property as about 50 acres west of Kingston, with Spectrum Community School and North Kitsap County School District bus maintenance occupying part of the former missile site and the rest undeveloped at that time.
