SS Trojan was propelled by a device called a quantum rod, which tunneled through spacetime by attracting together related matter which emerged from the Big Bang.
The Trojan was left derelict in space and was eventually discovered by the crew of Red Dwarf. Rimmer's brothers had all served on similar ships and he was very glad to have a similar vessel, despite the fact that it could not move under its own power.
When they made contact with Howard Rimmer aboard Columbus 3, Rimmer convinced his friends to pretend to be the crew of Trojan (Dave Lister is David Listerton-Smythe, Kryten is Kryten Krytenski and Cat is Gerald Hampton). Rimmer dressed himself in the captain's uniform and the rest of the Dwarfers as officers to convince his brother that he was a successful space adventurer. In fact, the ship was being towed by Red Dwarf and the crew had to pretend to work her controls, even leaning to mimic a change of course. ("Trojan", Series X)
- SS Trojan is the likely origin of Pree, the predictive A.I. computer that Kryten and Rimmer attempt to install as the new main computer on Red Dwarf in the next episode with disastrous consequences. Although the origin of Pree is unclear, Kryten mentions that they picked up the computer recently from a derelict.
- The quantum rod that the Dwarfers recover from SS Trojan plays a significant role in the later Series X episode "Entangled". Kryten experiments with crystals from inside the quantum rod, and it causes Kryten and the nearby Cat to become quantum entangled.
Behind the Scenes
- The Dwarfers wear the uniforms of the original crew of SS Trojan during their ruse, which resemble those of Star Trek: The Next Generation.
- In the script, the Dwarfers were originally meant to have stowed SS Trojan inside a landing bay aboard Red Dwarf. However, Doug Naylor decided that it would make more sense in the story to have Trojan towed behind the Red Dwarf, since Rimmer was embarrassed by his own ship and did not want his brother to see the Red Dwarf.
- The original FX for these unused shots can be seen on the Series X DVD documentary, "We're Smegged".
