With images like these, it's no wonder California — not to mention the Twittersphere — freaked out Saturday evening when an unannounced test of a submarine-launched Trident missile lit up the evening sky.
Photographer Porter Tinsley and her wife were on the shore of California's desolate Salton Sea taking long exposures and time lapses with three different cameras when they witnessed what they thought at the time was a chemical or nuclear weapon detonating over Los Angeles two and a half hours to the west.
"We thought everyone in L.A. was going to die," said Tinsley, whose blog has even more photos.
Fat chance. The pyrotechnics Tinsley and thousands of other casual skywatchers observed Saturday were due to the first of two Trident 2 D5 missiles with dummy warheads the U.S. Navy test fired between Saturday evening and Monday afternoon. The big, bright flash some mistook Saturday for a detonation, missile intercept or UFO is actually the result of the solid-fueled Trident missile jettisoning one of its three stages.
The test occurred the same day U.S. Secretary of Defense Ash Carter, speaking at the Reagan National Defense Forum in Simi Valley, California, called out Russia for engaging in "challenging activities" at sea, in the air, in space and cyberspace.
In a statement issued Monday night, U.S. Navy Adm. Ceil Haney, head of Strategic Command, described Saturday's test flight — one of 156 such tests since 1989 of the Lockheed Martin-built strategic "demonstrate[s] the readiness of our nation’s nuclear triad and serve to assure our allies and deter our potential adversaries."
Monday's test, conducted in the afternoon, caused far less brouhaha than Saturday's test, which was widely documented on Twitter and social media by unsuspecting skywatchers as far south a Mexico.
Strategic Command does not announce Trident tests ahead of time in order not to tip off U.S. adversaries who might want to watch and learn.
Among the select few not caught off guard by the test were five U.S. lawmakers, including Sen. Joe Donnelly (D-Ind.), who were onboard the submarine, the USS Kentucky, to watch Saturday’s launch with Haney and others.
