Abstract: A vehicle having a ceramic radome includes a vehicle body having an opening therein, a ceramic radome sized to cover the opening of the vehicle body, and an attachment structure joining the radome to the vehicle body to cover the opening. The attachment structure has a substantially cylindrically symmetric compliant metallic transition element disposed structurally between the radome and the body. The radome is joined to a first end of the transition element by a first brazed butt-joint. A primary seal is disposed between the transition element and the vehicle body. A spanner nut overlies the transition element and has a first engagement to the transition element. A threaded engagement between the spanner nut and the vehicle body allows the radome/transition element assembly to be attached and tightened to the vehicle body and to be later removed.
