After listening to Tijani's explanation, Shire realized that the "Brenan Torpedo" of this period was different from the near-modern wire-guided torpedoes.
The biggest difference was that the wire of the "Brenan Torpedo" both controlled and transmitted electricity.
"It is equipped with an electric engine." Tijani explained, "Our batteries cannot store enough power for it to reach the target, and the generator is too large to fit into the torpedo body, so we use shore-based power generation to supply electricity to it."
The method of power generation made Shire chuckle. They even equipped this torpedo with a boiler room, using the boiler room to drive a steam engine to generate electricity, then transmitting the power to the torpedo. The entire apparatus was practically a small power plant.
