Hill Air Force Base, as a place and an economy.

The base publishes three gates. The South Gate sits on SR-193 just east of I-15 exit 334 in Clearfield, is open 24 hours a day, and holds the visitor center in Building 542, open weekdays 7 am to 4 pm, where every visitor and every first-time arrival processes. The West Gate is east of the Clearfield and Sunset exit 335, on the frontage side where Falcon Hill sits, open 4 am to 10 pm on weekdays and 8 to 6 on weekends by the gate-hours fact sheet, though a staler base page still calls it 24 hours. The North Gate, which the base also calls the Roy Gate, is at exit 338 and runs 4:30 am to 5 pm on weekdays only, with commercial inspections 6 to 3. From the east, US-89 to SR-193 is the road in.

A fourth is coming. The 1800 North Gate, a separate access point with its own roundabout meant to relieve congestion, is in early construction and slated to open in late 2027, with a Wardleigh Road detour on the northwest side of the installation beginning in mid August 2026 and the road realignment finishing by the end of 2026; the base's enhanced-use-lease office is running the project, which tells you it belongs to the Falcon Hill side of the map. Third-party sites list five gates with different hours; the Air Force publishes three, and the fact sheet is the authority.

The museum is the base as the public meets it, and it sits outside the fence: 7961 Cottonwood Street, Building 1955, at the installation's northwest corner by the North, or Roy, Gate, with no base access, no ID and no gate required, free admission and free parking. It is run by the Aerospace Heritage Foundation of Utah, founded in 1982 and open to the public since 1987, on Tuesday through Saturday from 9 am to 4 pm, closed Sunday and Monday and the major holidays, and it draws about 350,000 visitors a year by its own count. The address that circulates on Wardleigh Road is a base road, not the museum.

The collection is more than ninety aircraft, missiles and aerospace vehicles across the outdoor grounds and three galleries, the Hadley of 1991, the Lindquist Stewart of 1994 and the 90,000 square foot L.S. Skaggs Gallery that opened in 2024, and it includes a B-17G, a B-52G, an F-117, an SR-71C Blackbird and, newest as of 2026, an F-22A Raptor. The 2026 season runs an A-10 virtual reality flight for $15, free summer STEAM missions, and an Open Aircraft Day on September 21 with cockpit access, F-22 pilots and crews, food trucks and music, all free. It is one of six museums in Utah accredited by the American Alliance of Museums, it houses the Utah Aviation Hall of Fame, and the base itself uses it for ceremonies, the July 2026 change of command among them.

The 2026 Warriors Over the Wasatch air show did not happen. On April 14, 2026 the base announced that the show scheduled for June 27 and 28, 2026 was postponed to June 19 and 20, 2027, citing the need to prioritize resources for critical ongoing operations after a review of operational commitments, and quoting the then-commander that with current constraints the base could not guarantee the quality and scale that defines the show. Third-party event listings still carry the June 2026 dates, and as of August 2026 the base's own air show landing page still shows the 2026 promo while its site navigation reads 2027; the April news release is the source of record.

The show is biennial, free to the public, and features the Thunderbirds among its performers, with paid VIP seating sold through the Utah Air Show Foundation and folding chairs welcome. The last one, June 29 and 30, 2024, ran on free general admission with free shuttles from assigned on-base and off-base parking to the entrance, and UTA has historically run shuttles from the Clearfield FrontRunner station; no 2027 transportation plan exists yet, and no attendance figure for 2024 was ever published by the base or the foundation, so the honest description is a large crowd across two counties on one weekend every other June.

Hill runs one of the busiest airfields in the Air Force at about 45,000 operations a year, and most of them are F-35As from the active-duty 388th Fighter Wing, three squadrons and 78 jets, and the Reserve 419th flying alongside. The 388th got its first F-35 in September 2015 and sent its last F-16s away in September 2017, so the F-16s you still see are depot aircraft on functional check flights by the 514th Flight Test Squadron, which certifies F-35As, F-22s, F-16s, C-130s and A-10s after overhaul at the Ogden Air Logistics Complex; transient military aircraft, U.S. and foreign, come and go for depot work and range time. There is no based tanker unit.

The base's own noise page is unusually specific about what a neighbor hears. When winds exceed ten knots operations flip from taking off and landing to the south to taking off and landing to the north, so the loud side of the base changes with the weather; inversions and low cloud trap and amplify sound; afterburners are used only on takeoff and in emergencies and are normally out by the end of the runway; nothing flies below 500 feet except on takeoff and landing; night training is required for both wings and is anticipated to be finished before midnight with residents notified. The booms are separate: sonic booms from the range, munitions drops, and rocket-motor disposal detonations at the Utah Test and Training Range, typically two or three times a week from April through October, can carry to the Wasatch Front under the wrong sky.

The published planning fact is the 2018 Air Installations Compatible Use Zones study, which updated a 1993 study and maps the base's noise contours and accident potential zones across Davis and Weber counties. Noise is measured as the day-night average sound level over a year with a ten decibel penalty added between 10 pm and 7 am, the same metric the FAA and EPA use, and the study reports that under existing land use there are 678 acres of incompatible development inside the 65 decibel contour, which may increase as residentially zoned land builds out. Accident potential zones run 15,000 feet off each runway end along the extended centerline, with 293 acres of incompatible development inside them today, and the study is blunt that flight tracks are not roadways in the sky.

Two sentences on that page matter to anyone buying near the base. Local governments, not the Air Force, control development beyond the fence, and the study's recommendations to Davis and Weber counties and the nearby cities are overlay maps, noise-reduction building code provisions and height ordinances; and, in the Air Force's own words, there is no formal disclosure of military operations required by law, but the Air Force recommends buyers be aware of noise zones and accident potential zones near military airfields. The land-use planning around that study is the Hill Air Force Base Compatible Use Plan, sponsored by Layton City on a Defense Department grant with Clearfield, Sunset, South Weber, Roy, Riverdale, Ogden, South Ogden, Uintah, Washington Terrace and both counties participating; which specific cities fall inside the 65 decibel contour is on the study's maps and not stated in its text, so this page does not name them.

Before the base grew into its present footprint, Clearfield had a different federal giant. Naval Supply Depot Clearfield was commissioned on April 10, 1943 as part of the Navy's post-Pearl Harbor supply buildout, held about a tenth of the Navy's covered storage at its peak, and ran three shifts around the clock with roughly 8,000 workers. The Navy closed it in 1962 and in July 1963 it was privatized as the Clearfield Freeport Center, a warehousing district built on Utah's freeport tax exemption for goods in transit, which is where the name comes from.

Today the operator's own numbers are 680 acres with sixty more set aside for growth, 78 buildings from 4,000 to 400,000 square feet, more than seven million square feet in all, more than seventy companies and a workforce of more than 7,000, with rail docks on one side of the buildings and truck docks on the other, twenty miles from the Salt Lake airport with direct I-15 and I-84 access. The historic footprint that circulates, 841 acres and 68 storehouses, describes the wartime depot and not the modern park; the two sets of figures belong to two eras and are kept apart here. The state's own records center is one of the tenants.

Falcon Hill Aerospace Research Park is 550 acres on the base's west side along I-15, straddling both counties, developed under an Air Force enhanced-use lease that the developer calls the largest in the Air Force and one of the largest commercial ones in the Defense Department, a fifty year agreement won by Sunset Ridge Development Partners, a Hunt Companies and Woodbury Corporation venture, in 2008 after the state created the Military Installation Development Authority in 2007. Its first project, finished in 2012, was a 150,000 square foot office building inside the fence built to suit Northrop Grumman's ICBM support work, alongside a new security forces building and the West Gate itself; the developer's own page says about a hundred of the 550 acres are built and other sources claim far more, so this page publishes no built square footage.

The reason the aerospace park is there is the missile work. The Air Force Nuclear Weapons Center is headquartered at Kirtland in New Mexico, not here; what is at Hill is its ICBM Systems Directorate, stood up on August 27, 2024 by merging the Sentinel and Minuteman III directorates, and the Ogden Air Logistics Complex's 309th Missile Maintenance Group, which supports 450 Minuteman III launch facilities across five states, stores and moves the boosters, and dissects the rocket motors. The Sentinel program that replaces the 54 year old Minuteman III is mid-restructure, with a milestone decision targeted for the end of 2026 and initial capability in the early 2030s, and it will build new silos rather than reuse the old ones; a prototype silo was to break ground in February 2026 at Northrop Grumman's Promontory site in Box Elder County, which is a long way north of the base and gets confused with it.
