 In April 1977, the navy lost the Cape-class patrol boat "P-11", with reports blaming the loss both on a storm and on an attack by the Eritrean People's Liberation Front (EPLF).If she was lost to EPLF action, "P-11" was the only Ethiopian Navy ship ever lost in combat.The Ethiopian Navy contributed nothing to Ethiopias victory over Somalia in the Ogaden War of 1978, and Mengistu increasingly began to divert resources from the navy to the Ethiopian Army and Ethiopian Air Force.
