Abstract: Both analytical and numerical models for the propagation of relativistic jets through a hot interstellar medium (ISM) and into an even hotter intergalactic medium (IGM) have been considered. The models by Gopal-Krishna and Wiita (1987), and Wiita and Gopal-Krishna (1987, 1988) were extended to allow for intrinsically extremely powerful jets, which may start off advancing relativistically through the interstellar medium. Eventually the energy density in the lobes becomes comparable to that of the microwave background, and inverse Compton losses of the synchrotron emitting electrons against the background photons become important. It is argued that only powerful radio engines are responsible for giant radio galaxies (GRGs, those whose linear size exceeds 1.5 Mpc), most of the observed peculiarities of the GRGs, such as their rarity, moderate radio flux and relatively strong radio cores can be explained.
