Design J3 November 1920
The J3 was an attempt to develop a design comparable in size to Hood. J3 was 860 (oa) x 104 x 29ft and displaced 43,100 tons with 151,000shp for 32kts. Armament was 3x3 15in, 6x2 6in, 6x1 4.7in HA, 4x 2pdr pom-pom mounts and two underwater 24.5in torpedo tubes. J3 was the only design of this series to have an external belt, 12in thick and still inclined at 25 degrees and a single flat armoured deck of 4in. This was the last of the non-transom hull designs. The design was not successful, the 15in gun was considered too small, it was still 1-1.5kts slower than Lexington and the armour was only proof against 15in fire and the deck armour was poor.
