HC Deb 24 February 1926 vol 192 c499
20. Mr. HORE-BELISHA

asked the First Lord of the Admiralty whether any new and improved device whereby a submarine may make its position known in the event of its being sunk has been fitted to submarines since the loss of the M1; and whether experiments have been made with any new device?

Mr. BRIDGEMAN

The answer to both parts of the question is in the negative. No device has yet been invented which improves upon the existing arrangements of which I gave some particulars to the hon. and gallant Member in my reply of 19th November last.

Mr. HORE-BELISHA

Since that date have no experiments whatever been made?

Mr. BRIDGEMAN

We have made our own experiments on suggestions made to us; other suggestions have either been considered before or are not considered of sufficient value to go to the expense of experiments.
