1942: Type 291 radar
Numerous and variable modifications as the war progressed, including restoring a second bank that had been removed in 1941 and adding a few more 20mm guns, updated radars, and HF/DF. |
The "J" class or Javelins were
completed in 1939-1941. The
design was developed partially in response to criticisms of the
previous "Tribal" class,
which was
thought to be too large and too gun-oriented. The new design was
smaller and more balanced, though the desire to use a dual-purpose main
armament was thwarted by the lack of a really suitable weapon.
The ships were somewhat wet but otherwise had good seakeeping. Machinery
dispersal was somewhat inadequate, due to the decision to go to two
boilers with a single funnel, but the use of
longitudinal framing imparted great
hull
strength.
Their balanced design ended further discussion of constructing separate classes of attackers (emphasizing torpedoes) and counter-attackers (emphasizing gunnery), and their basic hull form would be adopted for the mass production destroyers of the war years.
