Heavy Strategic Bombers (heavier, stronger, and costlier strategic bomber).Light Bombers (hybrid between CAS and a tactical bomber).

Night Fighters (twin-engine fighter specializing in interception).Heavy Fighters (redesigned to have role of a heavy fighter-interceptor and/or fighter-bomber).Multi-Role Fighters (twin-engine escort fighters with considerable ground support ability, particularly later in the war).Revised AI ship design that allows AI to script historical models better than in vanilla Rebalancing of combat and production statistics, including an across-the-board reduction in fuel and IC costs Revised effects of naval terrain and night combat gives more realistic combat balance NEW! Rebalancing of naval IC production caps (now 5 NIC for smaller ships and 8 NIC for capitals) This adds over 160 historical ship variants for the 1936+ unlockable through decisions. Historical existing models at start-up plus an expanded version of the RPM-TWAS Historical Ship Variants mod (made specifically for this mod. NEW! Historical Existing and Decision-Based Ship Variants: Restructured module slots for hulls makes it harder than in vanilla to make ahistoric meta ship variants There is also a new heavy-medium (10'-12') gun battery, differential CV decks (early, improved, advanced-for more planes), regular and heavy minelaying equipment, and cruiser armor specific to heavy cruisers New naval module techs: many modules have one or more additional tech years for more flexibility in ship design. Additional hulls for all units, with consolidation of some hulls as subtechs of their main hull types Cruiser Submarines (SSC) (very large, long-range submarines with scout plane capabilities same as in vanilla but now with multiple hull models).Small Submarines (SSS) (smaller, short-range submarine, good for coastal patrols and minelaying).Large Submarines (SSL) (larger, stronger, and longer-range submarine).Light Carriers (CVL) (smaller, slightly slower, but much cheaper carrier).Heavy Destroyers (DDH) (generally larger, stronger destroyers).Escort Destroyers (DE) (slower, cheaper destroyers for either convoy escort, torpedo boat roles).As of Version 0.93 RPM includes: Expanded Naval Techs and Models
