Yes, Ace, two SPW-2 would be needed.

I cannot imagine how badly this vessel would trim with all of the weight of the turrets essentially being shifted to the stern.

Well this is a highly speculative drawing, I feel the most likely option would have been a forward launcher, though I suspect the fire-control radars would need to go aft for space and topweight reasons. I may well go back and redo this ship again, at the moment it doesn't 'look' right to me either.

Thanks for the catch on the two SPW-2, I'm no expert on US systems. I don't even know whether the 984, 992, SPG-49 set-up could even be made to work given the Talos system was probably designed for US radars. Would 984 actually offer a superior Talos system than the US conversions had? (though I suspect 984 lacked the range to fully exploit Talos' range).

984 was definitely too short-ranged to take full advantage of Talos, but I don't see why the British search sets would be incompatible. Pretty much all of the system-to-system handoff was manual or manual-assisted in those days.

It must be also remembered that many post war British radars were in fact Anglicized American radars like Type 965 which was comparable to SPS-6 and Type 903 to SPG-35.

Depends on whether the illuminator was coded or just straight CW. I don't see why British illuminator (not search) sets would have a problem with TALOS either.

Very interesting, even if unusual in it's narrowly-focused configuration.

GW58 June 1955

GW58 was an upgraded version of GW52A with the DNC's desired 4% growth margin and corrections to machinery weights (+200 tons). The result was effectively a repeat of the GW25C except for only two Bofors mounts. Armour was much reduced (1.5in Vs 4in) but stability was better 8.5ft GM Vs 6.75ft GM) and the missiles were stowed one deck lower. GW58 was considered the basis for a final design and for the first time reliable detailed calculations were made. The design was handed to the Controller on 15 June and sketch Staff Requirement TSD 2305/55 was written around it. Displacement was 15,400 tons (deep); dimensions 637 (oa) x 78 x 20ft 3in. Speed was 32kts deep and clean with four 30,000shp YEAD sets producing 120,000hp (32kts on 105,000shp), endurance 4,500nm at 20kts. Armament was two twin 6in, two twin 3in L/70, two twin 40mm L/70 and 48 Sea Slug missiles. The radar fit was one Type 901 director, six MRS-3, Type 984, Type 992 and Type 974. Self-defence Type 176 and Type 177 sonars were also fitted. Armour protection was 1.5in side and deck except for the machinery areas which had 1in deck armour. Complement was 80 officers and 970 ratings.

GW60 August 1955

GW60 was the result of sketch Staff Requirement TSD 2305/55 was written around the GW58. The main differences were the provision for a VDS set instead of the usual Type 176/177 self-defence Asdics and space for the Y200 powerplant then under development.
Displacement was 15,800 tons (deep); dimensions 657 (oa) (645 wl) x 78 x 20ft 3in. Speed was 33kts deep and clean with four 30,000shp YEAD sets producing 120,000hp (32kts on 105,000shp), endurance 4,500nm at 20kts. Armament was two twin 6in, two twin 3in L/70, two twin 40mm L/70 and 48 Sea Slug missiles. The radar fit was one Type 901 director, six MRS-3, Type 984, Type 992 and Type 974. A self-defence Type 176 sonar was likely too. Armour protection was 1.5in side and deck except for the machinery areas which had 1in deck armour.
Further developments came at the request of the DNO who wanted either four twin 3in L/70 or two twins and two sextuple 40mm L/70 mounts. These became GW64 and GW69 respectively, while GW64A was DNC's design project with 6 extra Sea Slug missiles (54 total).

Very interesting.
And much better looking than Talos-design. ;)
