High atop the Santa Monica Mountains, overlooking the sprawling city of Los Angeles, lies a hidden history. This is the story of Nike Missile Control Site LA-78. Can you feel the ghosts of the Cold War era? Nike Missile Control Site LA-78, activated in 1963, played a crucial role in the nation’s defense. It was a silent sentinel, watching for potential airborne threats. The site formed a vital part of the Los Angeles defense area, a network of sixteen nuclear Nike missile sites. These sites protected key assets, including the aerospace industry and military installations.
Nike Missile Control Site LA-78 was a complex operation. The site used powerful radars, the LOPAR, TTR, and MTR. These tracked potential targets and guided the Nike Ajax missiles. The missiles themselves were marvels of engineering. They were the first operational surface-to-air guided missile system. They had a command guidance system, meaning their flight path was controlled from the ground, from Nike Missile Control Site LA-78. A computer calculated the interception trajectory. It sent course correction commands to the missile, ensuring a precise hit. The missiles carried three high-explosive fragmentation warheads. These were detonated by ground command when the target and missile paths intersected.
The Los Angeles defense area had some unique characteristics. Several sites, including LA-78, were located on high terrain, like mountain ridges. This provided optimal radar coverage. But it also presented challenges, such as substantial snowfall. This required buildings with peaked roofs. The threat of forest fires was also a constant concern. Nike Missile Control Site LA-78’s original partner launch site was located at 1900 Rambla Pacifica. Both locations were part of a system designed to protect a vast amount of territory. The Los Angeles defense area included sites on ocean shore bluffs. It also included others on mountain ridges over 8,000 feet high.
The Los Angeles defense network was eventually reduced from brigade to group status in 1968. Nike Missile Control Site LA-78 was deactivated in March 1974, along with the remaining Nike Hercules sites. The site itself has since been obliterated, leaving little physical trace of its existence. The original access road offers no hint of the critical role this site once played. However, the legacy of Nike Missile Control Site LA-78, and the Cold War era, lingers on. It’s a reminder of a time when the world held its breath, poised on the brink of nuclear war. It’s a testament to the technology and the people who worked tirelessly to protect our nation.
