HC Deb 19 April 1939 vol 346 c366W
Major Procter

asked the Parliamentary Secretary to the Admiralty whether, in view of the many advantages of dual-firing in the Navy, he will state the reasons why dual-firing has not been, and is not proposed to be, introduced in the Navy?

Mr. Shakespeare

Dual-firing is not proposed to be introduced in the Navy as a larger and more expensive ship for the same military characteristics would be required.
