Wulfen Battleship Neptune

The Neptune was a Dinsmarck-class battleship of the Neumenian Navy from 1932 to 1941, and the fourth of five Dinsmarck-class laid down in Ed Island. It first entered service in 1932 with the Ed Island Navy, but its crew defected soon after the Neumenian Reich was declared and the ship was named flagship of the newly-formed Neumenian Navy. The Neptune was the largest ship fielded by the Wulfen, and one of the largest of the Wulfen War second only to the Ed Islandian Waldersee-class.

Disappearance and Mythology
The Neptune received extensive modifications in 1941, removing much of its secondary armament and fitting four ballistic missile tubes in place of the central aircraft catapult. The removed turrets' magazines were replaced by a set of cargo holds, which were filled with an unknown cargo by the time the battleship set sail on its final voyage. Approximately two hours after leaving Ed Islandian waters, a single ballistic missile was launched which according to captured Neumonian communications was a Veil Society-derived two-stage rocket which put a communications satellite into orbit.

After launching the rocket, the Neptune proceeded to change course and began sailing towards the Culldrome Isles when communications with Neumonian command began experiencing difficulties. At 10:45 PM, all contact with the Neptune ceased and could not be reestablished. Initially the ship was believed to be sunk by an Ed Islandian U-boat, but no announcement of such an event came. The Wulfen War ended before further investigation could be initiated, and the Neptune's disappearance remained a mystery for 70 years.

Trivia

 * It is theorized that the cargo carried aboard the Neptune was related to the Veil Society portal technology. In 2011, a single life preserver bearing the Neptune's name was discovered at a Veil Society ruin within the Borderworld, finally shedding light on the ship's disappearance.
