The missile comprises a nose, fixed fins or movable fins, gas rudders, propelling nozzles and blast pipe inserts, combustion chamber liners, tail cone, grid fins, fluid elements and radome or subcomponents of these made of carbon fiber-reinforced silicon carbide (C/SiC) and/or carbon fiber-reinforced carbon (C/C) and/or silicon carbide fiber-reinforced silicon carbide (SiC/SiC) which are integrated in a missile structure. The missile components may be made of C/SiC and/or C/C and/or SiC/SiC with continuous fiber reinforcement and/or chopped fiber reinforcement or combinations thereof. The missile components may be prepared by mechanical machining of C/SiC and/or C/C and/or SiC/SiC blanks either in a single piece or by co-infiltration with carbon or silicon or silicon carbide and/or co-siliconizing of separate C/SiC and/or C/C and/or SiC/SiC segments to result in a monolithic structure. Cooling of the missile components may be achieved by providing cooling ducts and/or recesses in the C/SiC and/or C/C structure and/or the SiC/SiC structure and/or by means of insulating materials such as carbon fiber felts or C/SiC or C/C or SiC/SiC or graphite sheets or combinations thereof.
