began june launch june cleared building slip actually laid april intention launch october normal building schedule maintained early russians believed war soon workers diverted important projects war production began interfere deliveries material beginning shortly delayed launch october proposals evaluated building modify light issues demonstrated class service proved trim badly bow wet forward proposal fit forecastle deck improve rejected additional weight forecastle raising forward barbette actually trim forward proposal add meter forward accepted work continued slow rate february revolution unsettled times disrupted construction delayed renamed russian democracy april estimated complete industrial unrest strikes slowed progress provisional government postponed work october favorable time captured march occupied germans austrians incomplete hull january listed planned completed included navy list january mentioned order list renaming short lived orders actually implemented remained russian civil war use victorious soviets finally inspected worth completing dilapidated state design caused conclude worth sold scrap efforts sell hull abroad raise hard currency
