War Emergency Ships

[Desertfox]

Well I can't ask alot of a 600 ton ship, and 21kts allow it to run away from BBs, CBs, and older ACs. Also makes it useful as a Blockade ship. What can I gain by reducing speed? Not much.

Another Emergency Ship, this one replacing the TB Destroyer LC, as I can build 4 of these for every 1 LC. Designed to engage Chinese TBs so uses the 3" gun for its faster ROF. Uses a large quantity of wood in its construction and Army guns. Low draft allows it to hide from larger ships.
