Poseidon

aka Poseidon IX –Multi Mode Fast Attack

The Poseidon series of Attack Submarines reached the peak of their popularity during the Markan Wars which was mostly fought on and under the seas of Markan 1 and 2.

The first models were exclusively made to function in water, but starting with Poseidon IV they were redesigned and equipped for independent spaceflight with Arti-Grav and ISAH pods standard.

Only the Poseidon IX model ever saw actual combat, although the first Poseidon Xs had arrived in the Markan System prior to The Union's intervention that ended the war.

As with their other military hardware of both sides, most Poseidons involved in the war were destroyed as a part of the enforced peace, with only a handful ending up in museums or in the hands of private individuals.

In 5016 there was a space battle between a Poseidon IX and a pirate ship disguised as a Space Bus. It was later revealed that the pirate had been hired by a food MegaCorp to deliver a P Bomb to Nilfeheim. The Poseidon was commanded by Academy Pre-Enlistment Trainee Eric Olafson and crewed by Sif Arnske, Elena Olafson and Astrid Mossberg (who died as a result of a puncture in the engine room where she had gone in an attempt to put out a fire caused by a previous hit.) The boat was heavily damaged it was not repaired but it had been cast in a block of transparent Duranium and sat on a base of Duro-Crete in the Astrid Mossberg Park of Halstaad Fjord. It was intended to remind everyone how close Nilfeheim came to be completely destroyed.
