The TIE Experimental M4, alternatively referred to as the TIE Bomb, represented a guided missile system that leveraged TIE Series technology, emerging as an element within the broader TIE Experimental Project.
This unique starfighter, a product of an Imperial research initiative, was masterminded by Director Lenzer under the direction of Grand Admiral Demetrius Zaarin. The M4 was conceived as a cruise missile, intended to obliterate both formidable capital ships and fortified space stations. Incorporating wing panels directly sourced from the TIE/sa bomber, along with a similarly designed central pod and wing struts, the TIE M4 carried a payload of explosives capable of unleashing five times the destructive power compared to a kamikaze strike by a TIE/LN starfighter.
The TIE Experimental M4, incorporating an amplified booster in conjunction with the standard Twin Ion Engines, demonstrated superior linear acceleration when compared to a TIE/D Defender, while maintaining the maneuverability of a standard TIE Fighter. As a guided missile, the TIE M4 lacked any form of defensive armament. Echoing other TIE Experimental models, the M4 was operated remotely via a modified Beta-class ETR-3 escort transport.
The single recorded encounter between Rebel forces and the M4 transpired when the Empire launched a retaliatory attack on the cruiser, Liberty. In response, Liberty's fighter squadrons were mobilized for defense, successfully preventing the ship's annihilation.
Following the destruction of the hangar ship Sardis and the space platform Obsidian, no further sightings of TIE Experimental fighters were documented.
