Design GW90 / GW91 / GW92 Missile Cruiser

Description

These next 3 designs of the British GW series of missile cruiser designs.
On the GW 90 variant the designers wanted to further decrease the ship's displacement and keep it at 16.000tons (deep) and so they made the hull shorter but to provide sufficient accommodations for the crew and missile armament one twin 6inch turret was sacrificed.
The following study of GW 91 the designers took into account the previous meeting's discussions that the ship of 16.000tons was too small and could easily reach 18.000tons of displacement or more. The designers used methods and ideas from the County DDG design line meaning reduced staff requirements and thus smaller crew, but the absolute minimum displacement of this design was 17.000tons. To improve arrangements the GW 85 design was used as a basis but the middle 3inch twin turrets moved aft to reduce bending movement but this caused blast problems with missile guidance radars also aft. To solve this problem, on the next proposal of GW 92 the designers interchanged the aft missile launcher with the 2nd main turret, hence creating a more regular layout ship. The earlist of these designs showed up in April 23rd of 1956.

Data on the designs:
Dimensions: 185,93 x 24,08 x 6,55meters (GW90)
Dimensions: 196,60 x 24,08 x 6,55meters (GW91 and GW92)
Displacement: 15.932tons (17.000tons on GW91 and GW92) standard
Engines: 110.000shp 4 shafts
Maximum Speed: 59km/h (32knots)
Range: 8.300km at 37km/h (4.500nm at 20knots)
Armour: 38mm Belt, 38mm Deck
Sensors:
1x Type 984 3D Radar
1x Type 992 Air Search Radar
1x Type 978 Navigation Radar
1x Telemetry Aerial
2x Type 901 Fire-Control Radar for Slea Slug Missiles (one for each launcher)
6x Type 903 / MRS 3 Gunnery Control Radar (one for each gun turret, 5 on GW90)
Armaments:
2x2 152mm Guns (6inch) (QF Mark N5) (1x2 on GW90)
2x2 76mm AA Guns (3inch) (QF Mark N1)
2x2 40mm Bofors AA Guns (QF Mark 5 or Mark N1)
1x2 SAM (GWS.1 Sea Slug)

As there were no sketch for me to work on I deducted that double ended meant two missile launchers, one on each end of the ship. Though it is a possibility that the double ended design meant for the main armament. Sketches of these studies can be found at the National Maritime Museum of Greenwich, England but I don't have the means to get there and search through the documents and make copes of these sketches, hence I could only use the very models and sketch drawings posted in various naval books. If somebody could get a hold on these drawings and associated Admiralty papers in the museum and scan them that would be great, and a possible source for a small book about these ships.
