Stumbled across this on YouTube the other day and I thought some of you might appreciate it. Seems fitting that the trumpet to herald the impending doom of mankind was Hemi powered.

Trenton’s Chrysler air raid siren comes down
Trenton’s Chrysler Air Raid Siren
The 1951-1957 version used a 180 horsepower Chrysler Industrial V-8 engine, a Hemi design; it weighed around 5,000 pounds, and was over 11 feet long, 5 feet tall, and nearly 5 feet wide. It was completely self-contained, not requiring any functional public utilities. This version drove a three-stage compressor that blew 2,610 cubic feet of air per minute into a siren rotor, where it was sent out through six horns at around 400 mph, produced 170 decibels at the siren’s throat. The unit was designed to rotate at around 1.5 rpm on its base, with a range of 30-50 miles and a 70 dB signal for two miles.

Now that would make for a conversation piece at a car show!
I remember hearing those sirens in my youth! We had daily drills during the Cuban Missile Crisis and afterwards the sirens were tested on the first Friday of every month at 10:00 AM well into the late 1970s or mid-1980s. The last time that I heard an air raid siren test was sometime around 2003 in Huntington Beach. Our plant was across the street from Naval Weapons Station Seal Beach and I thought it might have originated from there.

It was!!
Did you see that guy in the background of the video I posted from Spring Fling 2009 Mopar show? He keeps moving back until he’s out the picture.
That video doesn’t do the sound justice.
I’m glad this was posted. The guy with the Hemi powered siren stores it much closer to our Fall Fling that’s at Irwindale this year.
...I gonna to see if he’ll bring it out.

Just another dumbass
I remember them as well. I heard them at the Ravenna Arsenal. Grew up about 25 miles from there in the late 60's and you knew when they were doing some kind of test for sure. They used to park one out by the Route 5 bypass entrance years ago. Went by there last summer and that entrance wasn't even there anymore. Place has changed so much. Looks like it was never even there.
