The three ships were Flight IV vessels, sold to Grayson between 1903 and 1904 PD. One of them, the GNS Joseph, was destroyed early in the First Havenite-Manticoran War, but the other two continued to serve in the GSN through most of the Second Havenite-Manticoran War. (GNLH) Ephraim was destroyed while docked at the Blackbird Yard during the Mesan Operation Oyster Bay in February 1922 PD. (HHA6.5: OS)
