Kroton battle fleet
From Tardis Wiki, the free Doctor Who reference
The Krotons had a battle fleet that fought against an enemy near the Gonds' planet. One Dynatrope carried out an emergency landing on the planet when two of its crew were exhausted by enemy fire. (TV: The Krotons)
It's possible the enemy was the Metatraxi, who warred with the Krotons at one point. (PROSE: Alien Bodies)
