1889 Arthur Krebs & Jean Rey periscope for the French submarine Gymnote. Periscopes allow a submarine, when submerged at a relatively shallow depth, to search visually for nearby targets and threats on the surface of the water and in the air. When not in use, a submarine's periscope retracts into the hull.
At depths below periscope depth submarines determine their position using: Dead reckoning course information obtained from the ship's gyrocompass, measured speed and estimates of local ocean currents, this could also be considered an estimated position as long as the ocean current is computed in.
Within minutes the submarine was again sighted from the air and was bombed. Two of the "cruisers" closed for a kill and nine depth charges were dropped at a distance of about 1,000 yards (910 m). When the attack ceased, Nautilus rose to periscope depth. Ships surrounded her. Sighting on Kirishima, she fired two bow tubes; one misfired, one ...
On the morning of October 24, 1944, the Tang was patrolling waters at periscope depth. Upon making radar contact with a large convoy, the Tang’s first targets were two transports and a tanker ...
[4] [15] In his book Submarine: A Guided Tour Inside a Nuclear Warship, Tom Clancy estimated the top speed of Los Angeles-class submarines at about 37 knots (69 km/h; 43 mph). The U.S. Navy gives the maximum operating depth of the Los Angeles class as 650 ft (200 m), [ 16 ] while Patrick Tyler , in his book Running Critical , suggests a maximum ...
Ballast tanks were almost never blown at depth, as doing so could cause the submarine to rocket to the surface out of control. Normal procedure was to drive the submarine to periscope depth, raise the periscope to verify that the area was clear, and then blow the tanks and surface the submarine. [26]
HMAS Rankin, a Collins-class submarine at periscope depth USS Charlotte, a Los Angeles-class submarine runs with submarines from partner nations during RIMPAC 2014. The first launch of a cruise missile ( SSM-N-8 Regulus ) from a submarine occurred in July 1953, from the deck of USS Tunny , a World War II fleet boat modified to carry the missile ...
An overhead plane spotted the submarine at periscope depth and a screening escort promptly steamed at 35 knots (65 km/h) toward her position. Once again, Harder became the aggressive adversary. As the range closed to 1,500 yards (1,400 m), she fired three torpedoes on a "down the throat" shot, then went deep to escape the onrushing destroyer ...
