OT: Chrysler air raid sirens

[Jim Altemose <jaltemoose@xxxxxxxxx>]

After Jim Rowland mentioned the "Red Ram" engine, I was poking around
on the Web and stumbled across the "Chrysler air raid siren".  To this
day, it's the loudest siren ever made.

Built during the post-World War II Cold War era from 1952-1957 by
Chrysler, its power plant contained a newly-designed FirePower Hemi
V-8, 331 cubic inch 180 horsepower (130 kW) engine.

Its six horns, were each three feet long. The siren could be heard
from a distance of 25 to 30 miles away and had an output of 138 dB and
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 three
tons.
