The Ekos was built to Mk I Loknar-class specifications and entered active service around reference stardate 1/9611 (circa the 2250s decade). On stardate 1/9904, the Ekos re-entered active service after a refit to Mk II specifications, which saw the ship equipped as a class VIII starship with increased tonnage and cargo bay capacity, new FWE-2 warp drive and modifications to phaser banks and torpedo launchers to fire FH-5 phasers (with an aft firing arc) and FP-3 torpedoes. The Ekos was later decommissioned around stardate 2/1410. (FASA RPG module: Federation Ship Recognition Manual)
