Minos

Minos is a lush, forested class M planet that once hosted a humanoid culture known as the Minosians.

The planet was visited by the USS Drake, and later the USS Enterprise-D in 2364. The Echo Papa 607, a sophisticated weapon system developed by the Minosians, was still active on the planet and had destroyed the USS Drake. It nearly destroyed the Enterprise as well, but was defeated. (TNG: "The Arsenal of Freedom")
