It would seem that the Royal Navy has been taking lessons from the tuna industry.
If you cannot beat them, join them; or at least try and make it look like you are. The Royal Navy is now supposedly using 'Dolphin-friendly' weapons. The Sunday Mirror is reporting that the Navy 'is testing a dolphin-friendly weapon following fears its explosives are killing marine wildlife.The device, a giant air gun, is designed to simulate a torpedo attack without harming dolphins and other sea creatures'.
We shall see! So far it would appear that they may have had entirely the wrong effect.
