U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Marinka: Bishii Maarso 1981, USAF waxay ku dhawaaqday barnaamijka Enhanced Tactical Fighter si loo helo bedel loogu talagalay F-111. Barnaamijka ayaa markii dambe loo beddelay tartanka Dual-Role Fighter (DRF). Fikradda ayaa loo maleynayay in diyaaradda ay awood u leedahay in ay bilowdo hawlaha hawada sare ee hawada sare iyada oo aan loo baahnayn taageero dheeraad ah oo ay bixiso duulimaadka dagaalka ama faragelinta. General Dynamics waxay soo gudbisay F-16XL, halka McDonnell Douglas uu soo gudbiyay F-15E. Diyaaradda Panavia Tornado ayaa sidoo kale ahayd musharax, laakiin maadaama diyaaradda aysan laheyn awood dagaal oo lagu kalsoonaan karo, oo ay weheliso xaqiiqda ah in aysan aheyn mid Mareykan ah, si dhab ah looma tixgelin.  Su'aal: Muxuu soo gudbiyay Douglas?
