Airborne Early Warning System Mr. Favell asked the Secretary of State for Defence what discussions his Department has had with General Electric Company-Marconi about a proposed new airborne early warning system to be developed with Lockheed. Mr. Butler I understand that the radar to be used in this venture is a derivative of the one under development for the Nimrod AEW project. GEC Avionics has, therefore, kept my officials informed of its plans. Mr. Favell asked the Secretary of State for Defence if he will make a statement on the implications for the Nimrod airborne early warning programme of the proposed joint development of an airborne early warning system by General Electric Company-Marconi and Lockheed. Mr. Butler I will answer shortly.
