For light fighters, this means a fleet of 1250 for 20% moonchance. In this case, only 3/4 of the ships must be sent. It must also be noted that on some universes, the debris field ratio is higher (for example on uni 40, it is 40% instead of the standard 30%). There is no need to go beyond 1667 light fighters, as 20% is the highest moonchance percentage available: more will not increase the odds. Alternately, 1667 small cargos can be used, as they create no damage to the 'fodder' defenses of the defending planet, and are easier to be defeated, though they are slightly more expensive. The most used way to generate the debris is to crash a fleet of light fighters 84 destroyed light fighters is 1%, and 1667 light fighters is 20%. Each 100k debris gives a 1% chance of producing a moon, up to a maximum of a 20% chance with 2M debris.

Any time a large battle occurs leaving more than 100k debris behind, the owner of the planet where the battle took place receives a moonchance, and if lucky, a moon.
