Naval Antennas & Radar. ( Bit of fun quiz )

[G7GPL]

I was in London yesterday on a job and had an hour to kill before my train back home. I am a photographer by profession so here is a pic of HMS Belfast. ( now a museum )

This ship at one time did have a ham radio station installed. ( don't know if it still has.)





The second image is a crop of the 1st one in the areas of the antennas and radar.

I have designated them with letters so who can surmise which one does what.?

In particular there are 4 black topped domes adjacent to the AAA and the secondary 4 inch armament. ( marked J ) What are these. Some kind of fire control for each.?



If anyone should be interested here is a brief history of this ship. http://en.wikipedia.org/wiki/HMS_Belfast_(C35)

B has got to be gun laying/director for the main armament - just because its on the optical director and thats the logical place!

Something similar to the USN's Phalanx system?



The Phalanx has a Vulcan gun, I believe.

Looks like R2D2 joined the Navy.

Looks like R2D2 joined the Navy.

And he's very HAPPY to see you!

And he's very HAPPY to see you!

He looks as if his wife has picked an argument with him over breakfast before he went to work.

He dont look very HAPPY to me.? .......... I would rather have Mr. Phalanx as a friend and not an enemy. Unless that is a picture of Mrs. Phalanx.!!!!! ( that would explain much. )

Doubtful... Belfast was decomissioned long before the advent of Phalanx or similar systems. It's more likely they are tubs for a single or double 20mm Oerlikon cannon. These were widely used as anti-aircraft weapons during WWII and after. I know they were still in service when I joined the Navy in 1965..

I think H is the "Huff-Duff" or HF direction finder, used for triangulating on U-boat report signals.

Thank you for that picture. Ships make worthy photographic objects because, as Conrad said, "Nothing can deface the beauty of a ship." As a ham, I say, nothing can deface the beauty of such an antenna farm. Had I the money, I'd have such a mast, array and assortment.

Her signal flags show, on the inner halyard C35; on the outer, GGCN--which, I assume, is her HM naval call sign. C35 may be a fleet signal, I suppose, but I'm neither British nor tar to understand it.
