HC Deb 21 July 1981 vol 9 c92W
21. Mr. Nicholas Winterton

asked the Secretary of State for Defence whether his Department has made an assessment of the reliability of the Ada computer language for defence control purposes.

Mr. Pattie

My Department has always been aware of the problem of the reliability of computer-based defence systems. It regards the Ada language as offering the opportunity to develop even more reliable systems than in the past, since it is potentially better than any language currently available to the Department for the programming of critical defence systems.
