NU Ship Hobart

Few months from becoming the RANS 1st Air Warfare Destroyer

ASC is building 3 AWD for the Royal Australian Navy. Hobart being the 1st of class.
Here she is returning from a week of sea trials.

very nice Peter, esp. the last one...

Last one is a cracker Pete.

I have a question, the slightly pinkish/magenta tinged panels on either side of the front of the superstructure, are they also repeated on the rear? I ask because I see no sign of a traditional long range air search radar, like on the US AEGIS Ships. You could though do it with a set of synthetic aperture arrays, that steer the beam electronically. Those panels look to be about the right size for that. It would be odd though for an Air Warfare ship to only have essentially side and forwards looking search radar.

I also really like the last photo too.

Here is a link to the unclass info on the class.

I could tell you but I'd have to. eh

Yes Alan. The ship is Aegis equipped the same as the US Arleigh Burkes. There are four phased array antennas around that structure.
She's 1st of three and will be the most powerful ships our navy has ever had.

Here's the backside.

Glad you like.

Ah thanks. I'm not really up with the latest in the way of shipboard radar systems. All I really know is the photos I've seen of the early US Aegis ships, the ones with the big rotating "Billboard" phased array aerials. Not that electronically steered phased arrays are anything new in the world of radar. When I was doing my RAF radar trade training back in 84/85 one of the systems we had at the training school used one. It was introduced into RAF service in the very early 1950's! The one we had at the school didn't have the aerial and, just dumped the Tx signal into a water filled dummy load. I suppose we could have used it as a giant microwave and done the brews for the whole training block, it put out 3 MW.

I'm actually glad I joined up when I did, since I was the last to work on the really big fixed installations using valve technology. The radar system I worked on for most of my time was the Associated Electrical Industries (AEI) Type 85, although it later became part of Marconi. In full war power mode it could push out over 60 MW (peak power) of RF @ 3GHz, down a beam that was 6 degrees high and 1 degree wide at the -3Db points. Burn though rules OK! The transmitters were fed with 1092 KVA of electrical power.

If anyone ever gets to Norfolk England I really recommend the Radar Museum at RAF Neatishead. The museum is in the old R30 Ops building and has contains the main control room, as it was when in use from 1966 to 1992. The room is just as it was when they closed that building and moved ops back to the R3 refurbished underground bunker. The R3 had been in use during the 60's but was destroyed by a major fire in 1966. The museum has a really good set of displays showing the development of radar and most importantly ground controlled interception methods. It also includes some of the more fun bits of the old T85 radar.

My last RAAF job was as a radar tech on the P3 APS115.
