Tractor plants in the service of Victory
Abstract
В годы Великой Отечественной войны все усилия советских ученых и инженеров были направлены на решение задач обороны. В самом начале войны сотрудники НАТИ совместно с конструкторами Сталинградского и Харьковского тракторных заводов (СТЗ и ХТЗ) создали на базе трактора СХТЗ-НАТИ бронированные машины, которые оборудовались вооружением для восполнения нехватки танков.
