Now it is time for the AU Broadswords.
At first glance you might think these are just warmed-over real ships but I have drawn these from scratch, they do have a lot of the Broadsword DNA in them but are designed for this AU and also owe something to my Type 19 design.
The main change is the VLS Sea Wolf (Confessor in the AU), with a 32-cell VLS fitted forward. While still lower than the 60 Sea Wolfs the real Type 22s could carry all of these are ready-use rounds (real T22 just 12).
In this AU the Type 22s are following on from the Type 19 Ikara frigates but have more focus on air-defence but still have boxed Ikara and Woomba to offer longer-range punch. The venerable twin 3in L/70 remains too. At least three of these ships will acquit themselves well in the Falklands. The 30mm atop the hangar are stand-ins, the Hawker Siddeley Shield having been cancelled they lack their intended close-in SAMs but Confessor does that job anyway. Post-Falklands the class gets beefed up AA defences with newer cannon, a 76mm Super Rapid (lightening the bows too), two Starstreak CIWS and the more compact Harpoon. Having splashed out on GWS-27 in my AU, the Type 22s get it alongside the Type 43 destroyers.

Which brings me to the Type 44 class. I had two brainwaves while drawing the Type 22; having a 32-cell VLS for Sea Wolf allowed enough room to put in a 24-cell GWS-30 Sea Dart 2, then I was reminded of the Jacob van Heemskerck class and by converting the hangar into a Sea Wolf VLS could have a powerful double-ender air defence ship to back up the Type 43s at lower cost. Therefore the real-world Type 44 conversion made much more sense in this AU given the VLS arrangements. The radar fit is perhaps not optimal but best that can be done I think with the available sets. In my AU, post-Falklands the planned Batch II Broadswords are replaced by Type 44s.

Gorgeous work! Your Type 44 in particular is very interesting. Glad to see this AU still continuing.

Whilst I do like the other scheme that I based mine off of, these are equally interesting.

These ships are much better than those real RN had. Well done Hood!

However, I remember seen in Type 82 and Type 43 a 3D rectangular radar similar with US SPS-39/52. The Type 22/Sea Dart would need that radar.

County Class NIGS Conversion

[ img ]
HMS Hampshire, 1964

I thought I would share this design which I drew following discussions around the NIGS SAM missile programme of circa 1959-61.
Some plan drawings of the NIGS missile system and magazine survive in the archives (the cross-section magazines are on the RN parts sheet already) and it was noticed that the ship's structure was that of a County-class destroyer. Indeed there seems to be some evidence that HMS Hampshire was considered for conversion with the system. The forward and aft launcher areas of the hull are based on the real plans and the centre section was blank so needed filling in. Here is a very likely layout for the proposed conversion, it looks extensive and crazy but the size of the system would have required such rebuilding. In reality the radars would have likely needed nuclear power for their energy needs but extra generators would have been fitted to the Hampshire if converted.

The NIGS system as depicted here:
1x2 launcher forward with 34x NIGS missiles plus 8x with nuclear warheads = 42
1x2 launcher aft with 38x NIGS missiles plus 8x with nuclear warheads = 46
4x New Surveillance Radar (NSR) radars with SCANFAR technology to search and track targets and the missiles
4x 5kw illuminator radars for the missiles

The rest of the radar fit is the usual Type 978 for surface search plus a Type 10 IFF bar atop the foremast. Two Sea Cat remain aft and a Wessex in the hangar.
