Fleet:

• A bug while using the keyboard for the in-game chat system in Naval Battles caused vessels to react to text has been fixed.
• US 40 mm Bofors cannons have been replaced by British models on the following vessels:
  • Class Dark (both boats)
  • Class Brave
  • Battle (D14)
• IJN Mutsuki - The maximum amount of torpedoes has been changed from 10 to 12.
• The maximum amount of ammunition for the 2pdr QF Mk.IIc autocannon on the Fairmile C and Fairmile C (332) boats have been fixed.
• HE shell icons, which displayed incorrect armour piercing values, have been fixed.
• The type and weight of explosive mass and initial speed for Japanese 100-203 mm shells have been fixed.
• Shell related errors have been fixed for the following ships:
• IJN Kuma - 140 mm type 2 SAP semi-armour piercing shell has been added for research.
• IJN Agano - 152 mm Type 4 SAP shell has been fixed. 152 mm Type 4 HE researchable shell with base fuse has been removed. 152 mm type 4 SAP semi-armour piercing shell has been added instead.
• Research points and in currency for removed modifications have been returned to those who purchased them.
• The type and weight of the explosive mass for the Japanese 610 mm Type 93 torpedo have been fixed.
• The name of the 76 mm OTO-Melara autocannon on the German Type 143 (Albatros) boat have been fixed, and the time it takes for the cannon to overheat has been increased.
• Ya-5M - The order, usage display, and reloading of rockets have been fixed.
• Pr.1204 Late - The name of the 76 mm D-56 cannon has been changed to the D-56TS cannon. A Cannon stabiliser has been added.
• A bug with “black” ammunition displayed in main calibre magazines on cruisers and destroyers has been fixed. If the main calibre ammunition Magazine is destroyed, it will now explode.
• The damage models of cruisers and destroyers have been refined:
• Overestimated bulkhead and deck thicknesses have been fixed;
• Side thicknesses have been increased on many destroyers up to 23 mm, which no longer allows many of the 88-127 mm shells to penetrate the ship enough to explode.
• Several ship modules such as pumps, fuel tanks, cisterns, transmission shafts, torpedo launchers and depth bomb launchers will no longer easily stop medium to large calibre armour-piercing shells. Now, with enough power, these shells will be able to punch through them.
• Transmission shafts, propellers and rudder feathers are now less susceptible to damage from shrapnel and explosions. Direct hits to these modules are guaranteed to damage or disable them.
• Fuel cisterns are now able to better absorb splinters, while allowing the armour-piercing shells to penetrate them completely if the shell has enough power to pass through the cistern.
• On ships with coal-powered boilers (Class Isles, Class Flower, SGB (S304)) their coal pits will now better absorb kinetic damage. It will be more difficult for armour-piercing shells to pass through them completely, but it may give off a lot of secondary fragments.
