This is a spaceship that I built in Tekkit Classic that has numerous operational systems within an appropriately compact space. Unlike many other spaceships, the interior structure and systems were built first, then the hull placed around it.

Features:
Computer Control
Weapon firing and switching system
Safety Airlock and Extendable Gantry
Nuclear Power Generation
Simulated Engine Power Consumption
Space-to-ground Oil Pumping and Storage
Efficient Use of Space
Highly Excessive use of MicroBlocks!

To-Do:
Add outputs for Yaw control
Exterior lights
Decoration and Detailing
