Attached 2 naval mines to my recent sparrow hovercraft build for anti-ship armaments! To lay the mines, just press and hold fire weapons to launch the naval mines.
The firing interval is around 2.5s between each mine, and arms once it slows down enough in the water. As long as you have the correct enemy selected, the mine will detonate within 200m of them, its ~1-ton payload killing most ships instantly and severely damaging even the USS beast with one mine.
Additionally, the mines have in built cameras to track its positioning, for a close up view of the explosion.
If you drop this mine over land, it still works as a dumb bomb, so you can use this against ground targets too!
If you want to save the mine as a subassembly, simply detach the flight computer, and save it separately as a subassembly. Then detach the rest of the mine by draggin from the detacher part, and save it as another subassembly. All the coding is built into the mine and computer, you need not copy over any code separately!
Hope you enjoy the build, and if you like the plane as well, do check out my sparrow hovercraft!
