The Imperial Type 5 Mine is a space mine that is similar to the Type C Mine, and was in service at least by the time of the Battle of Yavin. This stationary drone is lightly armoured and any damage sustained to its outer hull actives an automatic destruct mechanism, which also causes its concussion missile to be fired at the attacking target. As soon the mine detects a target that is not transmitting a pre-arranged transponder signal, this mine opens fire upon it with its laser cannon. Additionally, each mine is pre-programmed to recognize the transponder codes of authorized ships and fighters. Thus any ship not transmitting such codes or not transmitting at all are immediately fired upon by the Type 5 Mine. 200 of these mines are employed in the defence of Station 1B6/Green, which is located in the Darpa Sector.
