Ku dhammaystir weedha soo socota: Isku daygii ugu dambeeyay ee lagu joojinayo ololihii Mareykanka ee dib u qabsashada Filibiin, Ciidamada Badda ee Boqortooyada Japan waxay ku jabiyeen "Shō-Gō" 1, weerar saddex geesood ah oo loogu talagalay in lagu burburiyo ciidamada badda ee Mareykanka ee ku sugan Gacanka Leyte. Qorshahan ayaa loogu yeeray Ku-xigeenka Admiral Jisaburō Ozawa inuu u adeegsado diyaaradaha xamuulka qaada ee reer Japan sida dabin si uu u jiido diyaaradaha xamuulka qaada ee TF 38 ee Mareykanka ee ka baxsan buundada Filibiin, taasoo u oggolaanaysa Admirals Japanese Imperial Takeo Kurita, Kiyohide Shima, iyo Shōji Nishimura inay qaadaan ciidamada hawlaha dusha sare iyada oo loo marayo San Bernardino Strait iyo Surigao Strait, halkaas oo ay ku kulmi lahaayeen oo ay weerari lahaayeen buundada Mareykanka. "Iowa" waxay la socotay TF 38 intii lagu jiray weeraradii ka dhanka ahaa Ciidanka Dhexe ee Japan ee hoos imaanayay Amiraal Kurita markii ay ka soo gudubtay Badda Sibuyan ee ku wajahan San Bernardino Strait. Natiijooyinka la soo sheegay ee weerarradan iyo dib u dhaca muuqda ee Ciidanka Dhexe ee Japan ayaa u horseeday Admiral William "Bull" Halsey inuu aaminsan yahay in ciidankan loo burburiyay koox dagaal oo wax ku ool ah; natiijada, "Iowa", oo leh TF 38, ayaa uumiga ka dib Ciidanka Waqooyiga Japan ee Cape Engaño, Luzon. Bishii Oktoobar 25, 1944, markii maraakiibta Ciidanka Waqooyiga ay ku dhowaayeen meel u dhow qoryaha "Iowa", waxaa soo gaaray war sheegaya in Ciidanka Dhexe ee Japan ay weerarayaan koox ka mid ah maraakiibta xambaara Maraykanka ee ka baxsan Samar. Khatartaas oo ku wajahan ciidamada Mareykanka ayaa ku qasabtay TF 38 inay beddelaan jihada iyo uumiga si ay u taageeraan maraakiibta rakaabka ee u nugul, laakiin iska caabinta adag ee ay sameeyeen maraakiibta 7aad ee Dagaalkii Samar ayaa durba sababtay in Japan ay dib u laabato waxaana "Iowa" loo diiday ficil dusha sare ah. Ka dib markii
Dagaalkii Khaliijka Leyte, "Iowa" wuxuu ku sii jiray biyaha ka baxsan Filibiin isagoo ilaalinaya diyaaradaha xambaara inta lagu gudajiray duqeymaha ka dhanka ah Luzon iyo Formosa. Waxay u ambabaxday xeebta galbeed dabayaaqadii Diseembar 1944.
