Military Dolphins Discover 1800s Torpedo 112
First time accepted submitter 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. alongside the only other example."

Meant to be launched from above the water or submerged torpedo tubes, the Howell torpedo was made of brass, 11 feet long, driven by a 132-pound flywheel spun to 10,000 rpm before launch. It had a range of 400 yards and a speed of 25 knots.
Clever design. The energy in the flywheel was used for propulsion, but it also created a gyroscopic effect that helped it track in a straight line.
