Summary

A simple armed cargo ship

You just need to print the STL/STEP files of the ship and four copies of the gun mount STL/STEP files. They should be able to be directly installed on a cylindrical base and rotate freely.

If you want to convert it into an escort carrier, just print the escort carrier modification kit STL/STEP files. It should be able to be installed perfectly above the cargo hold. The yellow aircraft in the picture are fromhttps://www.printables.com/model/319852-simple-jet-planeAnd print it at a ratio of 15%.

The yellow goods in the picture are not my design. You can find them on the VOS supply ship page:https://www.thingiverse.com/thing:3057930

Both STL and STEP files are available, as well as FreeCAD (v1.0) files. Anyone interested in remixing or modifying them can use them.

Background story of the spaceship:

The "Lively"-class armed cargo ships were designed and built to respond to a turbulent era, when the turmoil on the high seas intensified and piracy and criminal gang activities became increasingly rampant, threatening global shipping. The four gun mounts equipped on the "Lively"-class

The "Lively" class has proven to be a versatile design, and a modification kit has been provided to convert this armed cargo ship into an escort aircraft carrier. Although its capabilities are not as good as those of a specially built aircraft carrier, the kit is very popular among small navies that want to add limited naval air power to their capabilities.
