While GW1 and GW2 were slow Convoy escort designs with Merchant like hull forms, the rest of the Convoy escorts were much faster and had much finer hull forms (hence the sharper nose and more angled aft part). GW3 was the fast equivalent of GW1 with somewhat longer hull but otherwise the same sensor suite and armament. Missile stowage the same as the previous proposals, eg "Deep Stowage"
The design had the following characteristics:
Dimensions: 149.05m (wl) x 21,34 x 5,41m
Displacement: 10.700tons (full load)
Engines: 30.000shp, Steam Turbines (Probably English Electric Y100), 2 shafts
Range: Unknown probably 15-21.900km at 22km/h (8-12.900nm at 12knots)
Speed: 45km/h (24,5knots)
Armour: unknown probably 51mm Deck over Machinery and Magazines, 89mm Belt over Machinery and 64mm over Magazines (Missile and Guns)
Armaments:
2x2 3"/70 (76mm/70) QF Mk N1 AA Guns,
4x2 40mm/70 OQF Mk XI AA Guns,
1x2 GWS.1 Sea Slug SAM
Sensors:
2x Type 901 Missile Control/Director Radar
6x Type 903 Fire-control Radar, one for each MRS.3 director
1x Type 960 Air Search Radar
1x Type 974 Surface Search/Navigation Radar
1x Type 982 Air Search Radar
1x Type 983 Height Finder Radar
1x Type 992 Target indication/Surface/Air Search Radar
