The graser torpedo was an advanced projectile weapon developed by the Mesan Alignment Navy. It was essentially an autonomous vessel with a single-shot cruiser graser, vaguely similar to a missile in functionality but creating a more powerful beam that lasted three seconds instead of five milliseconds. Using its own version of the spider drive, it was a large and cumbersome weapon, with the same trilateral symmetry as the Shark-class pod-laying strike ships which were used to launch it, as well as advanced electronic systems for covert coordination.
