What you
see pictured above is a Chrysler Air Raid Siren, the most powerful
siren in the world. It's the size of a car, measuring near 12-feet
in length and standing more than 6-feet tall. It also weighs twice
as much as today's typical car.
This
gigantic siren is powered by an 180-HP Chrysler Industrial V-8 HEMI® gasoline
engine. The super-duty engine directly drives a three-stage
compressor that blows 2,610 cubic feet of air a minute, at nearly 7 PSI,
into a giant siren rotor. The compressed air screams through the chopper
and out through six giant horns with an exit velocity of 400 miles per hour.
The result is
an incredibly loud 138 dB
sound (measured 100 feet from the siren).
The loudness
of this siren is unmatched by any other warning device ever sold, ever.
It's also considerably louder than the largest steam whistle or horn.
As if that were not dramatic enough, the whole unit, engine and all, slowly
rotates one and one-half times a minute on its iron turntable base.
The Chrysler Air Raid Siren is so
powerful that it can start fires with just the sound vibrations it produces.
It can turn fog into rain, clearing the sky.
It can produce
an effective 70 dB air raid signal for a distance of two miles, and
under proper conditions can be heard 30 to 50 miles away.
Its advertised range was four miles in every direction.
That's a long way.

The sirens Chrysler built were invented by Bell
Telephone Laboratories during World War II. Three different
production models of this siren design were made by Chrysler between
1942 and 1957. The Cold War model was the loudest and was built
only in the five years ending in 1957.
|
A few
hundred of these monstrous Cold War sirens were produced and sold during
the 1950's. Many remained in service for twenty plus years, sounding
only for routine tests. Most people who lived in major metropolitan
areas during the 1950's and 60's will remember the siren tests.
Those particularly, who lived in or near Los Angeles, Seattle, Kansas
City, Chicago, Detroit, Cincinnati, Pittsburgh, New York and even Miami
could hear the haunting siren wail of a Chrysler Air Raid Siren.

Because
of the extreme sound power emitted by these sirens and the desire that
their coverage area be extended as far as possible, they were usually
mounted high on a steel tower or on top of multi-story building.
As a result these sirens were always heard, but rarely seen.
For most
of the visitors to this website, this will be the first opportunity
they have ever had to see the siren that prompted "Duck and Cover" drills.

This website was created
on March 8, 2003, to collect and share information about one of the
most interesting sirens ever produced.
The driving force behind this website was the purchase of a Chrysler
Air Raid Siren by David Stall of Texas.
Mr. Stall
intends to see that his siren, dubbed the
VictorySiren™,
is fully and faithfully restored for a traveling public display.

In the short time that this
website, VictorySiren.com™,
has been online, the public response has been tremendous. It appears
that Mr. Stall is not alone in his fascination with the world's most
powerful siren.
|
After
only a month Mr. Stall acquired his second Chrysler Air Raid Siren.
This second siren arrived in somewhat working condition from Burbank,
California on April 16, 2003. It was promptly dubbed BigRed™.
Mr. Stall plans to paint the siren to match it's name and factory color,
restore this siren to good working condition and send it out to air
shows where it can participate in WWII reenactments.
