155mm Raytheon Excalibur


#1

I just came across this Raytheon video showing some effects of guided 155mm Excalibur projectiles.
While not showing much on the projectile itself the video quality is unusual good and shows some explosion dynamics in detail.
Well worth to watch.

Was that a tracer element burning on the rear of the projectile or a propulsion exhaust flame? Some of the shots appear to have been an air burst or VT type fuse. 2.2 meter error … pretty impressive considering the ranges indicated.

Sportclay,

I think that projectile uses what is called “base bleed” to optimize range by reducing drag.

As Dave said it is a base bleed unit:

There are different payloads available ranging from HE to HEAT submunitions and sensor fuzed submunitions.

Here some basic info:

Here another Raytheon HD video from this series - as good as the first:

BAD BOYS, BAD BOYS,
WHATCH GONNA DO?
WHEN EXCALIBUR
COMES FOR YOU?

Yes, that is a base bleed burning in oder to reduce drag forces.
What is also interesting is the vertical plume of white smoke with every explosion. The HE of the warhead itself produces black fumes, but the vertical smoke plume is white. What can it be?


#7

Maybe the remaining base bleed composition being pulverized and burning all at once?
Or any of the other components of the projectile which is containing all sort of materials which do react all in a different way when exposed to extreme heat and shock?
