American aircraft manufacturers have begun to develop amphibian Grumman G-73 Mallard in the first half 40-ies of the last century. Американские авиапроизводители приступили к разработке самолёта-амфибии Grumman G-73 Mallard в первой половине 40-х годов прошлого века. Новое воздушное судно предназначалось главным образом для обслуживания авианаправлений с городами и населёнными пунктами, не имеющими возможность организации взлётно-посадочной полосы, причём, американские авиастроители работали не только на удовлетворение целей собственных авиаперевозчиков, но и на иностранные рынки, в частности, наибольшая востребованность в самолётах подобного типа наблюдалась со стороны Канады, власти которой намеревались организовать эффективное авиасообщение с северными районами, где устройство аэропортов было нецелесообразным, в то время как потребность в совершении авиарейсов в эти регионы явно имелась.
