Nike Missile Site LA-14 IFC, South El Monte California
Longitude: -118.01492220988400
This location was part of the Los Angeles Defense Area
Site ID: LA-14
Missile / battery configuration: Nike 2B/20A/8L-A
This site controlled the missiles at the Launch Area located here.
Site Role: IFC
A typical Nike air defense site consisted of two separate parcels of land. One area was known as the Integrated Fire Control (IFC) Area. This site contained the Nike system's ground-based radar and computer systems designed to detect and track hostile aircraft, and to guide the missiles to their targets.
The second parcel of land was known as the Launcher Area. At the launcher area, Nike missiles were stored horizontally within heavily constructed underground missile magazines. A large, missile elevator brought the Nikes to the surface of the site where they would be pushed across twin steel rails to one of four satellite launchers.
Elaboration on how Nike worked here.
Missile Type: Ajax
The Nike Ajax was the first in the Army's family of guided missiles, and the world's first operational, guided, surface-to-air missile system. Nike Ajax had a burnout speed of Mach 2.3, a range of 25-30 miles, and a ceiling of 65,000 feet.
Designed to carry either nuclear and/or high-explosive warheads, the Nike Hercules missile could attack supersonic aircraft operating at altitudes in excess of 150,000 feet and at a range of more than 87 miles.
LA-14 was the San Gabriel Valley's quiet piece of the Cold War. The missiles were not hidden in a wilderness or on a dramatic coastal bluff; they were tucked into the working edge of South El Monte and Whittier Narrows, close enough to neighborhoods, roads, parks, and industry to show how deeply Nike defense was woven into everyday Los Angeles.
LA-14 was associated with South El Monte and Whittier Narrows. The control area was on the hill country near the Rio Hondo and Workman Mill Road side of the valley, while the launch area lay closer to Potrero Road and the Whittier Narrows / South El Monte recreation and utility landscape.
The Los Angeles Defense Area was one of the largest and most complex Nike air-defense networks in the United States. By the late 1950s, Los Angeles was ringed by sixteen Nike batteries. The defended area included the port and shipyards, Los Angeles and Long Beach industrial districts, aircraft plants, communications and transportation corridors, nearby military installations, and a major share of the nation's aerospace industry.
Nike batteries were the Army's final layer of continental air defense. Air Force warning radars and interceptor aircraft were supposed to meet enemy bombers farther out. If bombers reached the target region, the Nike batteries around Los Angeles would use ground-based radar, analog fire-control computers, and surface-to-air missiles to attempt an intercept.
Most Los Angeles sites began as Nike Ajax batteries. Ajax was a liquid-fueled, command-guided missile with a conventional warhead. Selected sites were later converted to Nike Hercules, a larger, solid-fueled, longer-range missile that could carry either conventional or nuclear warheads. The Los Angeles Hercules-converted sites were LA-04, LA-29, LA-32, LA-43, LA-55, LA-78, LA-88, LA-94, and LA-96. The Ajax-only sites were LA-09, LA-14, LA-40, LA-57, LA-70, LA-73, and LA-98.
A Nike battery was normally a split installation. The Integrated Fire Control area, or IFC, contained radar, computer, command, communications, and generator equipment. The launch area contained underground magazines, elevators, launchers, missile assembly and test facilities, security structures, roads, utilities, and support buildings.
Site Configuration and Decoded Meaning
Recorded configuration: Nike 2B/20A/8L-A.Decoded meaning: The launch area had two Type B underground magazines. The authorized missile load was 20 Nike Ajax missiles. The 8L-A ending means 8 Ajax launchers.
Site History and Setting
The South El Monte battery guarded the eastern approach to the Los Angeles Basin and the San Gabriel Valley's transportation, industrial, and military-adjacent landscape. Its location made sense tactically because it covered a wide inland corridor rather than a coastal approach.LA-14's short operational life, 1956 to 1961, identifies it as an Ajax-era site not carried forward into the Hercules network. Unlike later converted batteries, it was closed while selected Los Angeles sites were being upgraded to the more capable, nuclear-capable Nike Hercules system.
Local history accounts place the launch area near Potrero Road in Whittier Narrows and the control area on the Workman Mill Road side of the hills. Later recreational and public-agency reuse altered the landscape, but the old launch-pad and storage-yard references show that some physical traces were visible after formal decommissioning.
The LA-14 story is also tied to LA-29. A Nike veteran who later served at Brea described the LA-29 and LA-14 IFCs as Puente Hills sister sites, a useful reminder that the Los Angeles ring worked as overlapping batteries rather than isolated posts.
Units and Manning
No single long-term battery assignment is as well documented for LA-14 as for Mount Gleason or Los Pinetos in the sources used here. The site is best described as a U.S. Army Nike Ajax battery in the Los Angeles Defense Area during the first Ajax generation.Nike duty at LA-14 would have centered on readiness rather than combat action. Crews maintained radar, communications, generators, launchers, elevators, missile test equipment, fuel or missile-handling systems, security fencing, vehicles, and fire-control procedures. The site existed for an emergency that never came, but it had to be able to respond quickly if aircraft penetrated the outer air-defense screen.
Post-Closure and Current Status
Sources describe the control area as obliterated in a police/fire training or public-agency context and the launch area as obliterated in a U.S. Army Reserve or park/recreation-area context. Site-specific public accounts suggest limited visible remnants or former missile pads may still be identifiable within fenced or restricted public-works areas, but the battery is not intact as a Nike installation.The closure of LA-14 fits the broader decline of the Nike system. By the late 1960s and early 1970s, the Soviet bomber threat had been overshadowed by intercontinental ballistic missiles, while the cost of maintaining large labor-intensive air-defense batteries became harder to justify. LA-94 closed in 1968, LA-29 closed in 1971, and the remaining Los Angeles Hercules sites were removed from service in 1974. Ajax-only sites such as LA-09, LA-14, LA-40, LA-57, LA-70, and LA-73 had already closed earlier.
Chronology
- Early 1950s The Army and Corps of Engineers selected permanent and alternate Nike sites around Los Angeles while gun batteries still formed part of the regional air-defense system.
- 1953 The Corps of Engineers Los Angeles District was obtaining properties for Los Angeles Nike batteries, using military property where possible and negotiating or acquiring non-DOD sites where necessary.
- 1954 to 1958 The permanent Los Angeles Nike ring came into operation, with Ajax batteries established around the basin, coast, mountains, and inland approaches.
- 1956 LA-14 entered active service.
- Late 1950s and early 1960s Selected Los Angeles batteries were converted to Nike Hercules. LA-14 should be treated according to its specific system type above.
- 1961 LA-14 was deactivated or removed from active Nike service.
- 1974 The remaining Los Angeles Nike Hercules sites were removed from service, ending the regional Nike mission.
