Longbow International (a joint venture of Lockheed Martin and Northrop Grumman) is developing the Cobra Radar System for the AH-1Z, based on the Longbow millimetre wave radar on the AH-64D Apache. Cobra is a pod-based radar that can be mounted on a wingtip or in a stores position. Cobra can automatically search, detect, classify and prioritise multiple moving and stationary targets. It has a range of 8km against moving and 4km against stationary targets.
