XY-100 STA

The XY-100 STA, or space tug assembler, is a tug designed to push big objects like a fuel tank into a certain orbit. It is able to reach the orbit of the ISS from a 65k orbit height, so if you want to, you can use this module to assist you in building it. It contains a nuclear engine that has 790 Newtons of thrust, a TWR of 3.42x when fully unloaded, and an ISP of 376, all while using water to deliver a burn time of 66 seconds. The good thing about using this engine is that it has decent TWR and is very efficient. The bad thing is that it takes awhile for the engine to throttle up and down, so be careful when calculating precise orbits. You can use these in the builds you upload but give me a little credit. This is the first craft i have uploaded so it doesnt have any immense detail.
