U.S.S. Armstrong NCC-57537

Challenger (II) class.^[2] In 2373, the Armstrong and the U.S.S. Drake NCC-70956 were ambushed by a Klingon battle group and took heavy casualties. After the battle, the ships docked at Deep Space Nine to receive medical aid.^[1]

At the beginning of the Dominion War, Zelik Leybenzon was assigned to the Armstrong as an enlisted security officer. He later received a field promotion after repairing a damaged phaser bank that had been written off by the chief engineer and chief of security.^[3]
