The 1950s saw dynamic growth at
Ontario International Airport (the airfield was designated "International" in 1946), with three major aircraft plants, including
Lockheed,
Douglas an,
Northrop, having facilities at the airport. A second runway extension of 1,200 feet was completed in 1956 and permitted the Guard's speedy
North American F-86 Sabres to land and take off at Ontario. The first extension (800 ft) came in 1952, and the third (1,800 ft) in 1962, each time to accommodate the faster aircraft being flown by what was by now the
163d Fighter Group of the California Air National Guard. All three runway extensions were funded by the Air National Guard as military construction (MILCON). The 163 FG flew F-86F aircraft from Ontario from 1956 to 1959, and F-86H aircraft from 1959 to 1965. In 1965, the unit transitioned to the
F-102 Delta Dagger and in 1968 was renamed the 163d Fighter-Interceptor Group (163 FIG). Operationally-gained by the
Aerospace Defense Command (ADC), the 163d continued to fill what was primarily a coastal air defense role for southern California, Nevada and Arizona. In 1975, the unit transitioned to the
O-2 Skymaster forward air control aircraft and was re-designated as the 163d Tactical Air Support Group (163 TASG), with operational claimancy transferred from ADC to
Tactical Air Command (TAC). In 1982, in preparation for transition to the
McDonnell Douglas F-4 Phantom II and return to its earlier designation as the 163d Fighter Group, the 163 TASG transferred to
March AFB in nearby Riverside. Non-flying CA ANG operations continued at the site with the
148th Combat Communications Squadron until 1997, when Ontario ANGS was closed due to
BRAC action and the 148th transferred to the renamed
March ARB. == Closure in 1995 ==
