Ben Eielson High lab rebuild is part of Eielson AFB's F-35-era buildout

Phase 3 construction documents released Tuesday by the U.S. Army Corps of Engineers Alaska District detail rebuilt gas service and new emergency shutoff controls for science labs at Ben Eielson Jr./Sr. High School on Eielson Air Force Base, southeast of Fairbanks. The work itself is small — a propane tank swap, four lab rooms upgraded, new shutoffs and panels. But it sits inside a major federal infrastructure buildout at Eielson that has been reshaping the installation, the surrounding school district, and the Interior Alaska Air Force footprint for the better part of a decade.

The lab work

The existing above-ground 1,000-gallon propane tank and its fenced enclosure come out; a 250-gallon buried tank with concrete ballast goes in. Inside, four lab rooms (physics, chemistry, science prep, biotech) will each get key-operated shutoff valves on 60-minute timers, emergency gas shutoff buttons tied to the fire alarm panel, and a visible indicator light over each door when gas is in use. Shutoff and pressure-reducing valves sit in lockable panels accessible from both inside and outside. The design follows NFPA 54 standards. Existing lab sinks contain asbestos-containing material requiring regulated handling.

The bigger Eielson story

The 354th Fighter Wing, the host wing at Eielson, received its first F-35A Lightning II fighters in April 2020 — making Eielson one of only two operational F-35A bases in the U.S. Air Force's Pacific Air Forces region. Two F-35A squadrons (the 355th and 356th Fighter Squadrons) are now based there, supporting U.S. Indo-Pacific Command and serving as the Air Force's primary F-35 presence north of Hawaii. The 168th Air Refueling Wing (Alaska Air National Guard) is collocated at Eielson, and the installation supports the Joint Pacific Alaska Range Complex — one of the largest air training ranges in the world and host venue for Red Flag-Alaska exercises with allied air forces.

The F-35 mission expansion brought substantial additional personnel and military dependents to Eielson. That growth has rippled out to the surrounding civilian infrastructure: housing, commercial services, and the Fairbanks North Star Borough School District schools that serve military families on and near the base. Ben Eielson Jr./Sr. High School is one of roughly 32 schools FNSBSD operates and serves grades 7-12 directly at the installation; Crawford and Anderson Elementary schools also serve Eielson-based families.

The Corps of Engineers Alaska District has carried out a multi-year, multi-phase pattern of construction at Eielson supporting both the F-35 mission directly — hangars, simulators, maintenance facilities, personnel infrastructure — and the broader installation community. The science lab rebuild is one of the smaller, civil-side pieces of that work, but it's the kind of infrastructure that determines whether the schools serving an expanded military community can actually deliver the curriculum they're supposed to.
