Challenger II Tanks

HC Deb 02 December 1991 vol 200 cc54-5W

Mr. Home Robertson

To ask the Secretary of State for Defence what consideration was given to the use of a global positioning system in Challenger II tanks in the evaluation of alternative specifications between 1988 and 1990; and why it was decided not to use the system at that time.

Mr. Alan Clark

None. During the period in question, the specification for the Chieftain replacement included an inertial, rather than a satellite-based, navigation system. Subsequent experience in operating Challenger I in the Gulf demonstrated that a global positioning system would be adequate to meet our operational needs.

Mr. Home Roberston

To ask the Secretary of State for Defence whether the global positioning system proposed for Challenger II tanks can be used to transfer tactical information to other units as part of a battlefield control system.

Mr. Alan Clark

Yes, when linked with the necessary interfaces and communication facilities.
