It is the constant aim of my right hon. Friend and the Supply Ministers that production should be concentrated to the maximum extent practicable on equipment of the newest and most efficient types.
The transfer of production capacity to new types has, of course, to be arranged so as to secure the fullest effective use of plant and labour both during the transition period and in the build-up of the new production lines. My hon. Friend can rest assured that every effort is made to ensure that all such changeovers are made as soon and as quickly as possible.
