HC Deb 17 July 1972 vol 841 c12W
54. Mr. Tebbit

asked the Secretary of State for Trade and Industry what recent discussions he has had concerning the proposals to produce a stretched version of the RB211 engine to give more than 42,000 lbs. of thrust.

55. Mr. Whitehead

asked the Secretary of State for Trade and Industry when he expects to announce a decision regarding the funding of an uprated version of the RB211 engine, which in its initial production run has now received the British certificate of airworthiness, as part of the Lockheed TriStar.

Mr. Michael Heseltine

Rolls-Royce's proposals for a stretched version of the RB211 engine are under evaluation. I expect to be able to announce a decision in time for Lockheed to take its own decision on launching an extended range version of the TriStar aircraft.
