Паразитный истребитель-разведчик RF-84F FICON. Из парка RF-84F, имевшихся в распоряжении ВВС США, 25 самолетов были переоборудованы в вариант RF-84K (на фото) для авиационного комплекса FICON (Fighter CONveyor). В состав комплекса входил самолет-носитель, для роли которого был выбран Convair RB-36D (получил обозначение GRB-36D), и подвешиваемый к нему так называемый паразитный самолет (RF-84K). В бомбоотсеке устанавливалось Н-образное крепление, при помощи которого происходил сброс и прием RF-84K.
Designed to fit the Convair RB-36’s bomb bay, 25 examples of the droop-tailed Republic RF-84K were built, but served for only a short period with the 91st Strategic Reconnaissance Squadron.

Republic’s XF-12 Rainbow was the company’s only four-engined aircraft, and had a complete darkroom. Only two were built.
