1. In a gyro adapted to withstand a high-g launching environment, the improvement comprising:
- a gyro stator having spherical bearing surface means, a gyro rotor rotatably mounted relative to said stator by spherical bearing surface means, one of said spherical bearing surface means being metal and the other being a resilient material bonded to support material, said resilient material having a hardness ratio of about 0.49 to about 0.5 Poisson and a thickness of about 15 to about 30 thousandth'"'"'s of an inch to provide a thickness sufficient to withstand high-g launching environment of about 12,500 g load, and means in said stator for supplying fluid to said spherical bearing surface means to provide an air bearing space therebetween.

Abstract
A gyro in which an elastomeric material is used as a spherical bearing suce in an air bearing type gyro to sustain 12,500 g set back acceleration level during gun launch and have the capability of surviving the launch phase in a non-functioning mode and then being operative in post-launch lower-g environments as a stabilized/torquing seeker capable of tracking laser illuminated moving target so as to enable the gyro to be used for guided projectile systems.
