Combined air breathing rocket propulsion systems have been studied and carried through proof of principle demonstrations during the last three decades. Currently, a number of countries are studying and in some cases actually starting development of demonstrator vehicles for hypersonic flight which use combinations of air breathing and rocket propulsion. A summary of this activity including the propulsion options being studied is discussed. This type of propulsion is much more revolutionary in nature than most previous propulsion developments and thus results in technology challenges that are even more severe than those faced by either conventional air breathing propulsion or rocket designers. These include: (1) propulsion/vehicle integration; (2) engine stability over a wide operating range; (3) high performance over a wide operating range; (4) system level thermal management; and (5) advanced materials. A discussion of these technical issues including the impact of underachieved development goals on system level performance is also included.
