T2j Designed as Primary-through-advanced Trainer

Columbus, Ohio—North American Aviation’s new T2J-1 two-place jet trainer is designed as a complete pilot training system, capable of taking students from primary through advanced phases including Navy carrier indoctrination. Versatility of the airplane—first to be wholly conceived, engineered and produced at NAA’s Columbus Division—is such that it could shave at least a month from current student training programs, which involve switching to several types in the course of normal curricula.
