Ork Submersible
Yes believe it or not. GeeDubs actually created a model for an Ork Submersible and possibly the only aquatic vehicle in WH40K. Why they thought it was a good idea to make a model on a aquatic vehicle where 90% of all tabletops are all land base while the 10% that do have water are either too shallow or too small for this to be locally practical. The Submersible is also fucking huge, at the very least it is roughly the size of a Stompa so have fun trying to find a body of water big enough for this thing.
Anyways, the Ork Submersible is a thick hulled and crude submarine, heavy duty enough to negotiate even the harshest depths of oceans and storm-wrecked seas. They feature vast holds able to house large mobs of Ork infantry. The Ork Boyz who ride in bellies of Submersibles see them as huge aquatic Battlewagons, and embrace the new type of attack with a cheerful attitude typical of all Greenskins around the Galaxy. When the vehicle emerges from the depths, usually behind enemy lines, its great metal doors grind open and whole mobs of Orks pour forth, hooting and yelling as they splash through the shallows to engage the enemy from an unexpected quarter. Ork Submersibles are typically equipped with a bunch of torpedoes, artillery pieces known as Seacannons and sometimes a bunch of Big Shootas with which they support deploying troops once they're manoeuvred into position.
Ork Submersibles are first used during the Third War for Armageddon. Cannibalised and cobbled together from disused Imperial tankers, a whole flotilla of them was constructed in the Fire Wastes. This region was judged useless by Imperial Strategos, but Ghazghkull and Orghamek proved this a mistake when the Submersibles crossed the ocean to get to Armageddon Prime, revealing themselves around Hive Tempestora. This manoeuvre allowed Orks to conquer the Hive in mere hours of bloody and violent fighting. How the Imperium somehow missed an entire shipyard being constructed in one of the most heavily armed and populated planets despite having orbital ships to overlook the planet is a mystery.
Rules
Despite the Submersible miniature no longer being available from anywhere (not even eBay!), the rules can still be used in any games of Apocalypse, though we're pretty sure that anyone playing Apocalypse with an Ork player won't mind the use of custom miniatures, so don't sweat it.
