Submission + - Military Dolphins Discover 1800s Torpedo (dvice.com)
The0retical writes: A couple of mine-sweeping dolphins dredged up what is known as a "Howell torpedo" dating from 1870 to 1889. Only 50 were ever produced this being the second example known to exist. The 11 foot long brass torpedo had a maximum range and speed of 400 yards at 25 knots. The new example will be displayed at Naval Undersea Museum in Keyport, Wash. along side the only other example.
