When I was in a Navy airgroup (CVG-6 in the Fifties), it was standard
procedure to launch a concrete filled "wagon" off the cats after a
carrier left Portsmouth , VA yards to test the cats. The weight was
supposed to simulate an aircraft of the time. Difficult to plot the
trajectory from the flight deck but they went "way" out before arcing
down to the water.

Taking this way beyond reasonable speculation, has anyone else ever
wondered about the effects a missile like this might have on another ship,
as an emergency weapon :-)


I would think that a Model T would disintegrate
with the forces applied from a steam catapult.

Most likely. I figured they must have put the poor thing on a purpose
built sled or something. Then again, maybe it was just an item of roughly
the same mass as a T Ford, or maybe the whole thing is an urban legend.

The same would hold for any other car strapped to the cat; I doubt it
would be recognisable as a car the instant the cat fired.

I've seen some like that right out of the showroom...

With a hydraulic cat, maybe.
With a steam cat, no.

I dunno...but you can bet that it was the fastest mile(?) that it
ever clocked (and at the highest cost too!)...ole Henry must have
rotated a few turns in his grave!...

There are pics of cars getting catted off out on the 'Net, but I can't
find my copies on my computer right now.

As for the distance, nowhere close to a mile. If you make a couple of
reasonable assumptions - 100 feet off the water, and 130 kt end speed -
and do the math, it comes out to about 460 feet in 2.5 sec. This matches
well with what I saw during the deadload tests in port on the Midway.
Reduce either, and the "flight" distance decreases correspondingly.

Be fun to hear some Navy Dept. Admiral talking to the ship
damaged by the model T wouldn't it?...

"...Your ship was damaged BY A -WHAT- Captain??..."

I thought Dirk Pitt blew that up ten years ago...

Why has the speed anything to do with it Dave?...there's no
'lift' so it would fall just as fast no matter how fast it was
moving forward...it should hit the water just as quick whether
you shoved it off the side or accelerated it to a thousand MPH
(disregarding the curvature of the earth - and assuming that the
carrier deck is level fore and aft)

Given that your projectile is fired from a level flight deck and heads
for the water immediately, this would be an inconsequential "weapon". The
cat end speed necessary for the projectile to go a mile is over 1200 kt.

I would think that a Model T would disintegrate
with the forces applied from a steam catapult.

Most likely. I figured they must have put the poor thing on a purpose
built sled or something. Then again, maybe it was just an item of
roughly the same mass as a T Ford, or maybe the whole thing is an

Nope. Both pix I have seen of cars getting fired show a clearly
recognizable car going off the bow.

Just found this one - a Falcon going off the "E":
