Pfupisa nyaya yacho:  United Launch Alliance yakafumura zvirongwa zvakakomba zvokumutsa roketi rinoshandiswazve rinonzi 'Vulcan' muna 2019. Vulcan ichashandisa injini itsva, kupora pakati pemhepo uye nhanho itsva yokumusoro yakanangidzirwa pakugonesa miitiro yakaoma mumhepo. Kambani yacho inoratidzika kuva yakaita chiziviso chacho kuti chivhiringidze kuvhurwa kweFalcon 9 neSpaceX, iyo nhasi yaikarira kuratidza kuti maroketi anoshandiswazve anogona kushanda. United Launch Alliance yakafumura hurongwa hwekushandisazve roketi inonzi 'Vulcan' iyo yakarongerwa kusimuka muna 2019. Vulcan ichashandisa injini itsva, kupora pakati pemhepo uye nhanho yepamusoro nyowani yakanangana nekugonesa maitiro akaomarara epamhepo. Chinangwa cheSpaceX neULA ndechokugumisa kutsamira kweUnited States pamainjini emaroketi anogadzirwa neRussia, asi kusvikira zvino tekinoroji yacho yave ichiratidza kuva yakaoma. Mainjini eRussia akagadzirwa eRD-180 parizvino anopa simba roketi yeULA yeAtlas, asi Congress yakarambidza zvimwe zvinotengeswa kunze kwenyika sechikamu chezvirango zvekutengeserana zvakatemerwa mushure mekunge Russia yapinda muUkraine gore rapera. ULA yakati danho rokutanga reroketi idzva richashandiswa nemainjini maviri ane okisijeni yakawandisa nemethane yakawandisa ari kugadzirwa neBlue Origin. Mukuru Mukuru Tory Bruno akaudza musangano wenhau muColorado kuti injini dzichagadzirirwa kudzokera kuPasi, kuitira kuti dzigone kugadziridzwa ndokugadziridzwazve. Urongwa hweULA ndehwokurega kudzorera booster yose, nzira inodiwa nomukwikwidzi SpaceX. Inotarisira kuparadzanisa injini pashure pokutanga, kufuridza mudziviriri wokupisa wakavapoteredza ndokutumira helikopta kuti ivabate vari mudenga.

Kushandisazve injini kuchabvumira ULA kuderedza mari yokutanga kusvika kumadhora ane mamiriyoni 100 nokuda kwechinhu chinosimudzira chinosimudza uye anenge madhora ane mamiriyoni 200 nokuda kwezvinhu zvinosimudza zvinorema. Inenge hafu yemutengo weroketi yazvino yeDelta 4 Heavy yeULA. Pakutanga, ULA ichashandisa iripo yepamusoro-chikamu Centaur injini asi anoronga kusuma muna 2023 munhu yemhando yepamusoro injini kuti anogona recycle tsvina propellants. Maawa...
Vulcan inoronga kushandisa injini itsva, kudzorera pakati pemhepo uye nhanho yepamusoro itsva. Injini dzichaparadzana pashure pokubudiswa uye dzichatorwa neherikoputa iri mudenga. Maroketi anoshandiswazve aigona kugumisa kutsamira kweAmerica pamotokari dzemaroketi dzeRussia. SpaceX nhasi yakaedzawo kuratidza kuti maroketi anoshandiswazve anogona kushanda.
