What is TBT on a submarine?
submarine course and speed, which were read automatically from the submarine’s gyrocompass and pitometer log. estimated target course, speed, and range information (obtained using data from the submarine’s periscope, Target Bearing Transmitter (TBT), radar, and sonar)
Can a torpedo change direction?
As the torpedo leaves the submarine, the gyroscope is still lined up with the submarine and with the torpedo itself; the spinning mass will keep it pointing in the same direction, even when the torpedo changes its heading. After traveling a set distance (known as the reach), the gyro mechanism kicks in.
What happens if a torpedo misses?
Torpedoes that sank when they missed might detonate on the bottom. A number of reports of submarine attacks mention explosions from torpedoes that missed. Those that did not explode may remain in dangerous condition on the bottom, but every work I’ve seen on unexploded ordnance at sea focus on the more common mines.
How long does it take to flood a torpedo tube?
Research from first hand sources indicated about 1:30 to 2 minutes to be a reasonable figure for loading a torpedo into the tube on a 637 sub. The 45 seconds comes from the game originally being compressed into a half-scale environment where the flow of time becomes about 2x realtime.
How did ww2 submarines aim torpedoes?
When US submarines deployed the infamous Mark 6 magnetic exploder, the warhead included a self-destruct that detonated the torpedo at its end-of-run. While a Japanese ship might not be aware that it was a target, especially at night in choppy waters, the end-of-run explosion revealed the presence of the submarine.
How do you fire a salvo of torpedoes?
However, in order to complete firing a salvo of torpedoes it is necessary to commence shooting prior to this time. This is a function of target speed but for a medium speed target if firing is commenced with a 1200 yard torpedo run the last torpedo will be fired with the required minimum of 700 yards torpedo run.
How does the TDC fire torpedoes?
He fires each individual torpedo following the order SHOOT from the Assistant TDC Operator, holding the firing key down in each case a minimum of 5 seconds and times the firing interval to make sure that it is not less than that previously ordered by the Approach Officer. 571 – 579. BLANK 580. GYRO ANGLE SETTER:
What is a torpedo?
The torpedo is a direct descendant of the mine. During the American Revolution, kegs of gunpowder took the place of ships in the 1778 Battle of the Kegs. The first American use of the torpedo dates back to 1775 when David Bushnell discovered gunpowder could explode underwater.
How many fired as successive torpedoes are fired be announce?
As successive torpedoes are fired be announces TWO FIRED, THREE FIRED, ETC. 7-3 CONFIDENTIAL SLM 1 702. CONTINUOUS BEARING METHOD:
