Cosmo Messer E Release

by | Jul 4, 2022 | Blog, Pinned, Space Engineers


My first attempt at building a fighter completely from scratch. The Cosmo Messer is based on the Cosmo Zero from the Star Blazers (Space Battleship Yamato) series, and tries to strike a balance between performance and aesthetics.

Overall the handling is good, but not excellent. Acceleration is also good, but deceleration is inferior to more balanced designs. Lastly, the Cosmo Messer E’s standard weapons are light but can easily be expanded. The F, G, and K versions will have a lot more firepower out of the box, including loadout options.

There are no subgrids or modded weapons on this version.


The Cosmo Messer represents the Kaiser faction’s first foray into aerospace fighter design. Heavily inspired by the legendary BF 109 Messerschmitt, the Cosmo Messer strongly evokes the bygone era of dogfighting monoplanes. Since the Kaisers began favoring paired fighter tactics, most of the small ships sortie in even numbers. Their newer ships were designed accordingly, while their older ships were retrofitted to carry at least two of these craft.

Due to the Messer’s high mass and thruster layout, it leans heavily on ‘boom and zoom’ tactics to destroy targets. High speed passes also aid pilots in breaking off combat more quickly when the need arises.

Due to the uncertainties of deep space warfare at the time, various systems once only used on larger Kaiser vessels were tested on the Cosmo Messer. Some that made it to the production models include additional cameras, a ship integrity monitor, a projector for repairs afield, a lateral collision avoidance system, redundant hydrogen storage tanks, and a consolidated battery system.

The Cosmo Messer E was relatively successful, effectively ending the threat of ‘budget bombers’ in Kaiser space, however, the introduction of more and more powerful ships by other factions necessitates improvements to the Cosmo Messer far beyond what can truly be considered the E series.


The Cosmo Messer doesn’t require WeaponCore since it only uses vanilla weapons. The ship’s toolbar (second page) is set up for both uses though, so just delete the options you don’t need. The F series also won’t require WeaponCore but the G and K series will. Just a heads up.

Piloting Notes:
1: The Cosmo Messer E has only 2 side facing ion thrusters; it is not advised to turn off the hydrogen thrusters separately. Use Governor flight mode instead (Page 1 Num3) for low speed, smooth maneuvering.
2: The landing guide is helpful for landing in unfamiliar spaces. Activate the landing guide (Page 3 Num9) and keep the red areas from clipping through walls or objects. This will prevent lateral collisions.
3: For high speed braking, point the bottom of the ship in the intended braking direction. Additionally, flipping the ship can stop it much more quickly than relying on the reverse thrusters.
4: Follow a target’s movements slowly while firing the gatling guns, as the Messer’s long nose can catch rounds from the gatling guns during high speed turns and lateral drifting.
5: For connector landings involving multiple Messers, let the connector move the plane into position, then turn off thrusters and other systems before fully connecting. This prevents power toggles from affecting other docked Messers. Disconnect before toggling systems for takeoffs.
6: Can maintain altitude in up to 1.2 Gs of gravity. This is the upper limit; forward thrusters will be needed to gain altitude (nose up slightly).

You can also find this guide in the text area of the cockpit on the ‘numpad’ screen.
