Design and Development
The early 1960s concept was to provide the Royal Navy with a British-built torpedo to replace the imported Mk 44 and Mk 46 US weapons. In the 1950s the Royal Navy was equipped with British designed and built Mk 30 air-dropped torpedoes. These were passive homing weapons which relied on detecting the noise from submarine targets. However, as submarine noise levels reduced, these weapons became ineffective. Nuclear submarines could easily outrun and outdive the Mk 30.
A design for a British Mk 31 torpedo, which would have used active echo-location sonar, failed to receive Government approval for production and US Mk 44 torpedoes were purchased for the Royal Navy in the 1960s. These were later replaced by US Mk 46 torpedoes.

Famous quotes containing the words design and/or development:
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“The man, or the boy, in his development is psychologically deterred from incorporating serving characteristics by an easily observable fact: there are already people around who are clearly meant to serve and they are girls and women. To perform the activities these people are doing is to risk being, and being thought of, and thinking of oneself, as a woman. This has been made a terrifying prospect and has been made to constitute a major threat to masculine identity.”
—Jean Baker Miller (20th century)
