The Submarine elevates the term harassment to a new level. An invisible, silent killer, lurking in the waters, attacking without warning, and now also raiding the coast...this must be a commander's greatest nightmare (or wet dream, depending on which side he or she is on). They can be a boon should you be facing a larger enemy fleet, as most units cannot see submarines at a distance, making them easy pickings.
There is no good counter to Submarines, apart from constant patrolling of the seas with Destroyers. Brazil's Minas Geraes is an especially juicy target, as its enhanced power does it no good against submarines without a nearby Destroyer to detect them.
Submarines are the only hope of a civilization poor in Strategic resources to modernize their renaissance fleet: both the Ironclad (which is the upgrade of the Caravel), and the Battleship (upgrade of the Frigate) require such resources, while the Submarine does not!
Civilopedia entry Edit
When those madcap Confederates in the Hunley sank the USS Housatonic in 1864 AD, it launched a new age of naval warfare; unfortunately, the Hunley also sank itself, taking its crew to the bottom as well. Nevertheless, the submarine had made its stealthy appearance. The submarine, submersible, U-boat is a craft made for sneaking up on a target while underwater and then sinking it with torpedoes … or if possible surfacing and using its pathetic deck-guns. Germany pioneered their use as merchant raiders – really effective ones – during WW1, and expanded upon it during WW2, eventually sinking some 14.5 million tons of enemy shipping (including the odd warship) from 1939 through 1945. Advances in ballast tanks, power plants, control planes, hull plating and such sparked a “submarine-race” between the post-war superpowers culminating in nuclear-powered, deep-diving boats … armed with nuclear missiles that could be launched at population centers. What has the Hunley wrought?
- The Submarine's model is based on the American Gato-class submarine.
