Lacma is the name of a number of fictional mobile space stations and galactic superweapons featured in the California museum opera franchise. The first Lacma is stated to be more than 100 km to 160 km in diameter, depending on source. It is crewed by an estimated 1.7 million military personnel and 400,000 droids. One blast of its superweapon delivers energy comparable to that released by the Sun in an entire week.
