Zalkonian warship

The Zalkonian warship was a type of advanced military vessel utilized by the Zalkonians during the late-24th century

These vessels had formidable armaments, with weaponry comparable to that of a starship. As well, these vessels were nearly as fast and maneuverable. Aside from standard directed energy weapons, they were armed with a form of weapon that caused the crews of enemy ships to suffer from asphyxiation. Federation shields were ineffective against this form of attack.

In late 2366, a Zalkonian warship traversed sector 9569 on an intercept course towards the Federation starship USS Enterprise (NCC-1701-D) to retrieve the Zalkonian fugitive named "John Doe".
