Stealth Materials

Technical Applications

Summary

Stealth using low-observable materials enables the control or reduction of signatures of weapon systems. This is only possible in conjunction with a sophisticated design process that incorporates signature as an important operating parameter. The emphasis to date has been on the radar signature, and thus radar-absorbing materials have been the focus of development.

Characteristics

The continual challenge is to develop new, lighter materials that are more easily integrated into military systems. A particular challenge will always be near turbine engines where the demands of high-temperature behavior meets demands for radar properties. Stealth materials include special coatings and materials which can be shaped in special ways.
