HC Deb 17 March 1887 vol 312 c555

During 1886–87, great attention has been given to the development of defence against torpedo attack. A Committee has been investigating net defences; several of our battle ships are already fitted with this system of torpedo defence, and further experimental fittings are being tried on the "Hercules" and "Collingwood."

The torpedo experiments on the "Resistance" have also afforded valuable information as to the explosive power of the torpedo.
