This Air Raid Siren Sounds Like Something Off Of A Horror Movie Soundtrack

Built during the World War II and Cold War era from 1952-1957 (second generation) by Chrysler, its power plant contained a newly designed FirePower Hemi V8 engine with a displacement of 331-cubic-inch (5.42 l) and producing 180 horsepower (130 kW).[1]

Its six horns were each 3 feet (0.9 m) long. The siren could be heard from a distance of 20 to 25 miles (32 to 40 km) away and had an output of 138 dBC (30,000) watts. They were 12 feet (3.7 m) long, built atop a quarter section of a Dodge truck chassis rail, and weighed an estimated 3 short tons (2.7 t).

In 1952, the cost of a Chrysler Air Raid siren was $5,500.00.[1] (Approximately $43,966.48 in 2009 dollars.[2]) The United States government helped buy sirens for selected state and county law enforcement agencies around the country. In Los Angeles County, six were placed around key locations of populated areas, and another ten were sold to other government agencies in the State of California. These “Big Red Whistles” (as they were nicknamed) were only ever used for test purposes. Some were located so remotely that they deteriorated due to lack of maintenance. VIA – SuzukiBlaze
