Does anyone have any idea what this is?

It's on Foulness at the former MoD facility. Now Dera?

A quick Google gives out some interesting information about Foulness Island and DERA and the MOD, and firing things out to see.
What is the map ref of your image, some of the online maps let you get and angular view as opposed to a vertical view
First thought was a wind tunnel, but why it tapers like that?
Or maybe a weapons test range various targets being "loaded" in the gap halfway down?
Derek, 51.580172,0.858577. I think that's a location, unable to get 45 degree view or anything else useful.
It is a sonic research facility they used during the cold war to investigate "the brown note" as a means of incapacitating enemy troops.
Winky, I'd think it would have been dismantled by now if it was for brown pants noise? TonyIf its a wind tunnel for high-speed stuff, wind speed will increase as the nozzle narrows...

There doesn't appear to be any observation points at the fast end though.

How about a testing facility for the ultra high speed non explosive progectile?
Using magetic induction tech to produce such high speeds any contact with a projectile the size of a pea creates a pressure wave with which instant destruction occurs to the target. If I remember correctly it used some rather large capacitors..
I think it's a manufacturing facility for new camera zoom lens, as used by our naim photographers 
Like dis..?

Exactly Jamie, great looking lens. Why not go or a mirror lens that's more compact? ( genuine question)
no aperture so it's not possible to control the depth-of-field.
the mirror reflections eat contrast.
the overall sharpness is usually quite mediocre.
the secondary mirror produces an odd effect donut-like effect on the out-of-focus high-lights."
QinetiQ's projectile testing facility.

Just shows my lack of knowledge and skill.
Years ago I used to b big into the camera scene and particularly Motorsport photography. Used to use an 800mm mirror lens and thought it was great
That was in the days of my Minolta body and when the only option was film ( usually HP4 )
I didn't visit the site but it is the sort of thing done there.

You're talking about a Railgun. A favourite "boss weapon" in first-person shooter computer games, and in real life, just as awesome.
Winky, not sure if what I was talking about was a rail gun or not - the projectile is fired without explosives at all, and contains non either.
It was being tested on a navy boat when I saw the footage on tv. It did use a LOT of stored electricity, and the speeds attained were fairly staggering.
We all saw how much energy can be released by speed not so long ago with that meteor exploding in the atmosphere, with the force of a big atom bomb, and thats just a lump of rock!
It's the Iraqi Supergun!
Returned to sender as Parcelforce were unable to deliver it.
