What is this weapon spotted at an airshow in South Africa? I was at an airshow in South Africa, and they had this trailer sitting about.  No one knew what it is.



Those little red plates all say "warning, high voltage".  Those buckets are open at the bottom, and made of aluminium.



These finned pointy things are hollow, not sure what they are made of.  Were not solid plastic, but didn't look like fiberglass either.

A couple of specific questions:


What is it?
If the hollow things are covers, why are they so oddly shaped?  And if they are covers, why do they share features with liquid tanks?
Why are there half a dozen "High voltage" stickers attached?
What are those bins and chains?
@mins got this one right. It's a British Tigercat short range surface to air missiles launcher system. The cones are protective weather covers for the missiles which are removed prior to launch.

As to the 'buckets and chains' I'd venture a guess that they are a device to deflect and dissipate the rocket blast during launch but I am not totally sure. But they can be seen on YouTube (at 0:07 and 0:39).

From YouTube, on the right the blast being deflected up/down.
