[Cost & Equipment] 23 million Jansanian Ringgit per construction, 850,000 Jansanian Ringgit for each defence epilogue (maximum 5.9 million, it's expensive due to missile expenditure). [Background] In response to the increasing demand for urban protection within the Milky Way, Jansanian engineers recognised a unique opportunity to enhance their reputation among international powers by developing a domestic defence mechanism. Subsequently, these engineers acquired plots of land on a life-sustaining planet located in the Triangulum Galaxy to advance their endeavours. At first, they designed a detection system with several radars and antennas placed at all corners of the boundary's circumference. It works pretty well when incoming strikes are detected, though the signals are slow, so they use excessively high altitude electromagnetic pulse radars to detect incoming strikes faster, with the exception of the high energy consumption, thus they use SMRs as the main power source. With that tackle, the engineer's next consideration is to design the coordination of command bases, interception missile stations, and topography. The engineers hired urban planners to discuss and craft a layout. Now with everything prepared, the team starts the construction. For half a year, this project remained finished till the experimentation. The experiment was proven to be a success. [Blueprint] There are two layers, the zone of detection and the vault zone, with the zone of detection being perceptible by high altitude electromagnetic pulse radars from a far range. When the incoming propelled weapon reaches the zone of detection, the radar could spot it in seconds, observing its movement, the signal information was transmitted to the Command Centre, where the data was analysed by supercomputers, calculating which quadrant the incoming propelled weapon's trajectory will strike into using calculations to find the slope of the tangent line (derivative) and use integrals to know the collide quadrant. After collecting the data, directives were sent to the interception missiles, with the trajectory direction prompted in the directives, the launch pad could launch the missile in order for the missile to hit the incoming propelled strike.
