The Sidewinder and What It Cost to Invent It
Near Ridgecrest, California
The AIM-nine Sidewinder, the heat-seeking air-to-air missile that became one of the most widely deployed weapons in the history of aerial combat, was developed by a small team of Navy engineers at China Lake Naval Air Weapons Station between nineteen forty-six and nineteen fifty-three. The Mojave Desert was selected for weapons development because the sight lines are long, the population density is low, and test aircraft can fly without endangering cities. The first successful intercept test was in nineteen fifty-three. Variants of the Sidewinder are still in production.
What the Sidewinder's designers could not test for was geology.
On July fourth, two thousand nineteen, a magnitude six point four earthquake struck the Ridgecrest area, southeast of the China Lake base. The following day, July fifth, a magnitude seven point one struck the same region, the largest earthquake in Southern California in twenty years. The earthquakes were felt from Las Vegas to Los Angeles. Ridgecrest, a city of approximately twenty-eight thousand people whose economy is built almost entirely around the military installation that dominates it, sustained significant structural damage.
The China Lake Naval Air Weapons Station reported approximately two point five billion dollars in infrastructure damage, the largest loss from a natural disaster in Navy history. The weapons testing ranges were shut down for months while engineers assessed which structures were safe to reoccupy.
The desert that had been selected as a testing ground precisely because it was assumed to be remote and stable had produced the single largest natural-disaster infrastructure loss in the history of the institution that chose it. The scientists who study the region note that the two thousand nineteen sequence was part of ongoing tectonic adjustment along fault systems running beneath the entire Mojave. The desert was never stable. The engineers who selected China Lake in nineteen forty-three simply did not have the seismic data that would have told them otherwise.
Note: the two point five billion dollar damage figure comes from Navy reporting as documented by USGS and regional press coverage; it has not been independently verified by a second institutional source in the research for this track.
