The Ecol was a Leopard CV-class DropShip of the Lyran Commonwealth. During the sixth, seventh, and eighth battles of Hesperus II in 2853 it was carried to the Hesperus system's nadir jump point with the ancient battlecruiser LCS Invincible. The Lyran force smashed the Draconis Combine blockade force, destroying numerous DropShips, and the WarShips Wyrm and Yedo; only the WarShip Galedon II escaped.
The Ecol also took part in the subsequent battle on 10 November that broke the blockade in close orbit over Hesperus II.
