This adds over 160 historical ship variants for the 1936+ unlockable through decisions.

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).minor updates from vanilla patch 1.10.2.This mod should be playable for 1.10.2 both with and without the Man the Guns and La Resistance DLC (though most balancing, testing, etc., has focused on the version with DLC included).This is an extensive mod of the game and is therefore NOT compatible with most other mods.There is also some rebalancing of combat stats and improvements of historical accuracy for OOBs and the like.

The mod expands models and units through expanded tech trees and equipment that are common to all countries, though with historical models for all nations where applicable, and generic models where no historical model existed. The main purpose of this mod is an expansion of the available models, equipment, and units for naval, air, and land forces while otherwise staying true to vanilla HOI4.

RPM for HOI4 is an update of the original Realistic Progression Mod (RPM) for HOI3.
