When Han Solo and Chewbacca destroyed a Viper probe droid on Hoth, the droid managed to send relay images of Echo Base before self-destruction. After the Battle of Hoth, every TIE Series starfighter had a self-destruct system installed. The Empire equipped TIE Maulers with a self-destruct mechanism as a means to do additional damage to enemy troops if the TIE Mauler was attacked. The power core of the TIE Mauler would overload and the craft would explode, destroying or damaging troops, vehicles, or structures nearby. As late as 40 ABY, Slave I was equipped with a powerful self-destruct system.
