This ship is vanilla and survival ready. It does use DLC blocks for aesthetic improvements, but those blocks are entirely or almost entirely not structurally necessary. If you do encounter a major issue, please, let me know so I can resolve it.

Knightmare Industries presents the MCRN Arsia, a pure Ion Martian Frigate design. The Arsia is an updated version of the Wendigo with a few alterations. It's designed for long missions in deep space and is equipped for resupply on mission. The ship is named for Arsia Mons, a large volcano on Mars.

The Arsia's engines are entirely Ion to keep fuel requirements down. The main thrust is provided by 4 Large Ion Thrusters assisted by several Small Ion Thrusters. Power is provided by 1 Large Reactor, 16 Small Reactors, and a substantial Battery backup system. The ship is equipped with 3 Jump Drives, and is well armed with 12 Gatling Turrets, 8 Missile Turrets, 9 Interior Turrets, and 10 forward facing Rocket Launchers. The hull is mostly light armor, with heavy armor concentrated at the front and around critical areas. It is equipped with 2 Assemblers, 2 Basic Refineries, a Medical Room and Survival Kit, with 2 connectors for docking.

The ship is built fully vanilla and survival ready, with an interior in the style of "The Expanse." I use a light changing script to switch around the interior light settings. Its an older script and I couldn't find the original creator. The script was updated by ColTeH for my use. There are also a few other program and timer blocks if you need them. You may have noticed already, but the ship uses DLC blocks.

Please feel free to modify the ship to fit your in game needs. Just be sure to give credit to the original creator.


This design is a personal favorite of mine, and as I'm also a Martian fan, making an MCRN skin for it was inevitable. As I mentioned, it's essentially a Martian reskin of the Wendigo, albeit the updated Flight 2 Wendigo and with some fewer Interior Turrets. The ship is also built more for Space Engineers and less to be a realistic expanse ship, so it has more weapons and missile turrets, unlike the somewhat comparable Corvette Class Frigate that Mars operates in that show. You can think of the Arsia as the SE alternative to the traditional Martian Frigate design. I was tempted to make this a UNN design, but MCRN seemed to fit the overall aesthetic better.
