Radome E-2C Hawkeye (IMAGE) Naval Research Laboratory Caption NRL's proprietary phthalonitrile resins, developed by the Chemistry Division, were measured to have dielectric permittivity and loss tangent characteristics that make them ideally suited for use in radomes. The E-2C Hawkeye aircraft is the U.S. Navy's all-weather, carrier-based tactical battle management airborne early warning, command and control aircraft. The spiral painted on the rotating radome of this Hawkeye is the hallmark of the "Screwtops" of Carrier Airborne Early Warning Squadron 123.
