A pair of tracking torpedoes
Torpedoes with tracking capabilities were a specific kind of torpedo employed by Admiral Trench to counter ships utilizing stealth technology.
Based on Republic records documenting engagements with Trench, the Harch Admiral made use of tracking torpedoes to obliterate starships, particularly cruisers, equipped with cloaking technology.
During the events of the Battle of Christophsis, Trench's utilization of tracking torpedoes ultimately led to his downfall. Following multiple encounters with the Republic's prototype stealth ship, commanded by General Anakin Skywalker and Admiral Wullf Yularen, Trench targeted the ship's magnetic signature from his command vessel Invincible and launched a volley of tracking torpedoes. Skywalker then piloted the stealth ship directly towards the Invincible, narrowly avoiding its hull at extreme velocity, causing the torpedoes to impact the bridge of Trench's flagship, resulting in the ship's destruction and causing severe injuries to Trench.
