1. An interceptor, comprising:

  • an airframe having a longitudinal axis;

    a plurality of dorsal fins positioned about a circumference of the airframe and running parallel to the longitudinal axis, each said dorsal fin having a forward-facing surface that is substantially perpendicular to the longitudinal axis;

    an adaptive electronically steerable array (AESA) system comprising a plurality of AESA arrays, each AESA array placed on the forward-facing surface of a different one of said dorsal fins, each said AESA array comprising a plurality of radiating elements configured to emit radio frequency (RF) energy substantially perpendicular to the forward-facing surface and substantially parallel to the longitudinal axis;

    a plurality of RF transmissive radome elements, each radome element placed on the forward-facing surface of a different one of said plurality of dorsal fins over the respective one of said AESA arrays, each said radome element having an aerodynamic shape complementary to a cross-section of said dorsal fin; and

    control circuitry to configure the plurality of AESA arrays for RF target engagement.
