Nimrod nose radar.

Does anyone have a photo of the nose radar on an MR2 and R1 or are they the same.

The Nimrod R was originally delivered with ASV21 as fitted to the MR1. This was removed as part of the Astral Box programme ca. 1980 and an Ecko 290 weather radar fitted in the redundant searchlight housing on the starboard 4A tank. The display for the Ecko 290 was at the navigator’s station. The nose radome of the R1 contained no equipment as none had originally been planned and there was a limitation on weight growth for the airframe. The R1 frequently operated at a higher Zero Fuel Weight (ZFW) than the maritime aircraft. When operating at the Extended ZFW speed limitations where introduced at a lower in flight All Up Weights (AUW). The descent into Wyton took a long time at 235kts.

It’s the Searchwater 2000MR Radar/IFF antenna for what was going to be Nimrod 2000.

Racal Radar Defence Systems, manufactured in 2000 and NATO number taken out in 2003 (hence sticker) so too late for AEW Nimo

What about from an AEW.3 Nimrod ?

5841 – Radar Equipment, Airborne

Not sure, but it doesn’t look aero to me. May be some ground-based radar kit? There’s plenty to choose from! The operating wavelength would help, it might be possible to narrow it down to an application though I don’t know how you’d find that out.

Has anyone got a list of the NSN stock number descriptions?

Anon.

Ok thanks for that what about Hercules but it is some 4 feet across. I cannot think of anything else .

Definitely NOT Nimrod MR1, that had ASV21D fitted and that is not an ASV21D scanner, don’t know what it is.
