Darmok class

The Darmok-class was a type of advanced starship utilized by the Children of Tama in the 24th century. These vessels were equipped with systems comparable to that of a Federation starship.

Like all Tamarian vessels, ships of this class were adorned with symbols and artifacts that reflected their society's rich history and mythology. (CCG: Second Edition)

In 2368, a Darmok-class vessel commanded by Captain Dathan met with the USS Enterprise (NCC-1701-D) in orbit of El-Adrel IV, in the hopes of establishing dialogue between the Tamarians and the Federation. When initial attempts at communication failed, Dathan had himself and Captain Jean-Luc Picard beamed down to El-Adrel and then set up a particle scattering field so that they couldn't be beamed off.

The Enterprise attempted to dissipate the scattering field by firing on the Tamarian vessel, but suffered serious damage in return.
