A transparent domical nose fairing of a guided missile is coated with an interrupted metallic film and electrically connected to a power source for heating the fairing when icing is likely. The film is preferrably applied on the inner surface over substantially all of the transparent area so that it also acts as a shield against radio frequency interference. If desired the external surface may be covered by an antireflectance coating to enhance the "vision."
