Now that`s what I call Muzzle Blast !!!

[Grumpy]

During the course of an email conversation about naval guns a friend sent me this photograph of three 16" guns being fired simultaneously from a US Iowa class battleship.
Totally Awesome !!!
As can be seen, the forward guns are slightly out of sync`.

Again a good one.

It's nothing compared to what happens when Grumpy lets one go.

I got this in the email before and a few others. I found this on google.

Hi Sharief,

Those are very interesting photos.

Would you know the medium through which the bullet and pellet were shot through in the last pic?

Rusty, I have a Guns and Ammo that has a pic of a Glock 22C I think it is, that is similar. I googled for this term "schlieren photography", I'm sure you can read more online.

Here's Wiki for you:

No shockwave penpusher but a heck of a cloud of smoke - what is that, a human cannonball or something ?

[penpusher]

One of the three Paris siege guns, WWI.

- And I thought it was a human cannonball gun !
I know that up to Medieval times rotting animals used to be catapulted into besieged towns/cities/castles but I suspect that practice had ceased by WWI !

No shock wave but would have a hell of a muzzle blast.

HARP 16"

[Grumpy]

A project killed by Canadian politics and American inter-service rivalry.
The 16" HARP gun was the same type of naval gun shown on the battleship above. The barrels were progressively lengthened to increase velocity however. The photograph must have been taken at the initial Barbados test facility.
In 1966 the HARP/Martlet combination achieved an altitude of 180km from a firing at the Yuma, Arizona launch facility - still the world altitude record for a gun launched projectile.
A very simple, very clever idea which had far more potential than that realised.
