The Stone Arrow was the JumpShip of Willard Theodore "Kangaroo Jack" Puritan, a smuggler known to operate in Federated Suns, Lyran Commonwealth and Draconis Combine space. The exact type of the Stone Arrow is not mentioned.
Kangaroo Jack worked with Draconis Combine crimelord Grig Griez. It was the Stone Arrow that brought the Dark Wing unit to Ander's Moon during Operation Inroad in April 3024. He was subsequently tracked down by Gideon Braver on a world in the Federated Suns (randomized in the game, but usually Okefenokee or Tancredi IV) sometime between 3024 and 3028, but was murdered before Gideon Braver could talk to him; the assassin, a known gangland assassin known as Grim Jim, was also found dead. It is unknown what happened to the Stone Arrow afterwards.
The hunt for the Stone Arrow is part of the storyline of the MechWarrior computer game.
The game, and therefore its storyline, is apocryphal (see section about Canonicity in the game's article): It is expressly not included among the list of canonical sources for the BattleTech universe, but it has also been said that, until contradicted, information from certain sources including this one "can be assumed to be part of the shared universe if it makes sense". MechWarrior in particular is one of the computer games where the storyline is widely treated as canonical.
