Space Engineers BM-13 Katyusha
BM-13 Katyusha Rocket Launcher, sporting guided missiles.
Developed by the Soviet Union in 1939, still in use today by some countries. Originally would use rockets and fired via an artillery sight. Also known as the Stalin Organ.
UPDATE : corrected an oversight, warheads will now arm themselves after launch, no suicide Katyusha!
Controls are as follows
1 unlock launcher pivot
2 lower launcher
3 raise launcher
4 control designator
Designator Controls are,
1 view targeting camera
2 scan target coordinates
3 fire missile
4 turn on missile thrusters
I recommend turning on the thrusters before launching, as I found launching with them off lead to a misalignment and the missile becoming lodged in the rails.
