 On 5 July the DNC submitted two revised designs for the Admiral @-@ class ships . The first was a modification of the previous design with slight increases to the deck , turret , barbette , and funnel uptake armour , one @-@ inch protection for the 5 @.@ 5 @-@ inch ammunition hatches and hoists , and the number of electrical generators increased from four to eight . These changes increased the displacement by 1 @,@ 250 long tons ( 1 @,@ 270 t ) and draught by 9 inches ( 228 @.@ 6 mm ) . The second design drastically improved the protection and converted the ships into fast battleships . The vertical armour was generally increased by 50 % and the deck protection was slightly thickened as in the first design . These changes would have added another 4 @,@ 300 long tons ( 4 @,@ 369 t ) to the original design and increased the draught by 2 feet ( 0 @.@ 6 m ) , but would have cost half a knot in speed . This design would have been equal to the Queen Elizabeths , but 7 knots ( 13 km / h ; 8 @.@ 1 mph ) faster and with much improved torpedo protection , although it was some 13 @,@ 000 long tons ( 13 @,@ 209 t ) larger than the older ships . After the DNC submitted the above designs , he was asked to consider variations with triple fifteen @-@ inch turrets , and these were submitted on 20 July . The Admiralty chose the fast battleship design , and Hood was laid down again on 1 September .
