Submarine Applied Technology and Submarine Units (Submarine, Ballistic Submarine, Mini-Missile Submarine, Morph Submarine, and Morph-Missile Submarine) are detailed in this tome.

Submarine (Stingray)

Unit Summary: Should be used to take out naval forces, and when added to your own naval groups will protect you from enemy subs. Their camouflage enables them to sneak around on planets undetected.
Special Abilities: They can attack on Byzantium II, they do not consume food.

*Units with Submarine as a technology prerequisite are able to use materials twice as effectively for Camouflage.

Ballistic Submarine (Mauler)

Unit Summary: Very mobile Ranged Space defensive weapons and should be used accordingly. They become slightly less effective against naval units and so are not direct replacements for submarines.
Special Abilities: They can attack on Byzantium II, they will attack an enemy space unit landing within a 5 hex radius, they do not consume food.

Mini-Missile Submarine (Mite)

Unit Summary: Designed for harassing the enemy, their high speed, camouflage, and agility make them hard to find, track down, and destroy. If you can land some of these on an enemy's planet they should be quite the nuissance.
Special Abilities: They are the only loadable naval unit, they can attack on Byzantium II, they will attack an enemy landing unit within a 5-hex radius, they do not consume food.

Morph Submarine (Stalker)

Unit Summary: Morph Submarines are much more effective than Submarines, but have no Ranged Space capability and so are not replacements for Ballistic Submarines. Nevertheless, you should upgrade some of your Submarines to Morph Submarines reserving the others for Ballistic Submarines or the Morph Missile Sub.
Special Abilities: They can attack on Byzantium II, they do not consume food.

Morph-Missile Submarine (Banisher)

Unit Summary: Morph Missile Subs are much more effective than Ballistic Submarines, but their Underwater attack is not nearly as effective as a Morph Submarine's and so do not replace Morph Submarines. Submarines should be upgraded to Morph Subs or Morph Missile Subs as soon as possible.
Special Abilities: They can attack on Byzantium II, they will attack an enemy landing unit within a 5-hex radius, they do not consume food.
