The bright radio galaxy Hercules A (z = 0.154), has power P178MHz = 8 × 1026 W Hz–1sr–1 and although this puts it well above the FR break, its structure is intermediate between Fanaroff and Riley classes I and II. With a linear size of 334 kpc (for H0 = 100 kms–1Mpc–1), Hercules A possesses an unusual jet-dominated morphology and no compact hotspots. The western jet shows partial or full ring-like features that form a linear sequence heading from the core to the lobes and follow an inner jet.
