TzoliDesign II was the second in the series proposed for Jellicoe for a new construction battlecruiser. It is essentially the same as Scheme 1 but using Yarrow small tube boilers instead of Babcock & Wilcox type large tube boilers for the same 120.000shp. As you can see, development in engine technology allowed the designers to produce ships with smaller machinery space yet more power output! I calculate that around 20 Yarrow Small Tube boilers were required for the desired power output. This resulted in a much shorter proposal of roughly 14m shorter hull together with the weight saving in armour to protect the hull with a considerable 3.500tons sving in displacement! Otherwise like armament layout armour speed etc it is identical to that of Scheme 1.
The design had the following characteristics:
Dimensions: 240,79 (pp) x 253,1 (wl) x 256,03 (oa) x 31,7 x 7,92 meters
Displacement: 35.500tons (standard)
Armour: 203mm belt at 10°incline, 25mm over Machinery, 38mm over Magazines deck, 38-38mm slopes.
Engines: 120.000shp Parsons Steam Turbines, 4 shafts
Range: 14.200km at 30km/h (7.600nm at 16knots)
Speed: 56km/h (30knots)
Armaments:
4x2 15"/42 (381mm/42) BL Mark I Cannons,
12x1 5,5"/50 (140mm/50) BL Mark I Guns,
2x1 3"/42 (76mm/45) QF HA Mark I AA Guns,
2x1 53cm Underwater Torpedo Tubes
