I vaguely remember a sci-fi series that had a spaceship that used an alien weapon.

When this weapon was used it caused the ship (computer?) to power down for a minute or so and so they were vulnerable... or would have been if the weapon didn't work.

Any ideas as to the series name?

  • Any other details you can remember? Was this in the 80's? 90's? U.S.? British? Animated? Live action?

  • Could it be Farscape? Moya was the live ship.

  • @Willow - That wasn't a weapon though

  • @Valorum you're right -- her son had them but it did not harm him to use them.

This is Crusade, a short-lived spin-off of Babylon 5.

From Wikipedia:

Excalibur features energy and particle beam weapons. The main guns operate at two main power levels. "Level One" provides beams with little more firepower than a White Star. "Level Two" is much more powerful weapon, reverse engineered from Vorlon lightning cannon technology. [...] Firing this titanic weapon drains all the ship's power and the "Excalibur" is unable to maneuver, fire weapons or use long-range scanners for approximately one minute afterward.

    Crusade was going to be my suggestion as well, unless we're talking about anime, in which case it could be Space Battleship Yamato, which was also vulnerable after firing: en.wikipedia.org/wiki/… May 8, 2017 at 22:46
  • Yes, it does sound like Crusade. I'll check it out now. Many thanks.
