Republic XF-91 Thunderceptor

The Republic XF-91 Thunderceptor was a mixed-propulsion prototype interceptor aircraft developed by Republic Aviation. The aircraft would use a jet engine for most flight and a cluster of four small rocket engines for added thrust during climb and interception. The design was largely obsolete by the time it was completed due to the rapidly increasing performance of contemporary jet engines and was built to the extent of two prototypes only.
