Modifications

1942: Type 291 radar

Numerous and variable modifications as the war progressed, including adding a second torpedo bank (actually restoring a bank removed in 1941) and adding a few more 20mm and updated radars and HF/DF.


The Javelins were completed in 1939-1941. They were a well-balanced design, good sea boats with adequate armament. 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. Machinery dispersal was somewhat inadequate, but the use of longitudinal framing imparted great hull strength.
