The end escort agency nashville was a submarine tactic  used when the position of a submarine relative to a potential target did not allow the submarine to mount an immediate attack.
The submarine's crew estimated the enemy's bearingheadingand speed, remaining submerged until out indian independent escorts salford the enemy's visual range. The submarine then surfaced and proceeded at maximum speed to a position in front of the target, near the target's predicted course but remaining out of milpitas escorts.
The submarine would then submerge, approach, and attack. The location from which a submarine could attack varied mostly according to the relative top speeds of the attacker and its target.
Diesel-electric -powered submarines in the Second World War were typically capable of knots on the surface under diesel power and new middlesbrough escort independent to 9 knots underwater,    where they were restricted if lacking a snorkel to battery power. Battle fleets in World War II might have a top speed of up to 30 knots, making it difficult for submarines to achieve attack position.

A convoy of freighters or tankers typically proceeded at up to oakville oriental escort knots. Attack opportunities would also be lost if the target detected the submarine and altered course to avoid attack.
To attack, a sub usually had to get ahead of its target: the end around was one solution to this problem. If a submarine couldn't attack due to asian escorts new jersey positioning, its crew would determine the target's course and speed, then calculate a potential torpedo firing point.

The end around might then proceed as follows. The end around tactic was useful largely because of submarines' low freeboardwhich made them less visible than essex prostitutes merchantmen and warships.
Using the targets' superstructure and exhaust smoke to estimate escort santiago de chile maintain proper distance, a skilled sub commander could maintain a close watch on enemy ships while keeping his own vessel unseen. While not called "end around," this tactic was used by U-boats during World War I. A modification to this tactic incorporated the night surface attack, where the submarine remained surfaced during the actual attack, rather than submerging first.
This variation allowed the submarine to take advantage of its higher surface speed, but made pre-attack detection more likely.
This could result in a counterattack by escorts, or the targets could turn to spoil the attack. As a defense, ships can adopt zig-zag sailing patterns rather than more-efficient great-circle. Sailing in zig-zags made computing a target angle more difficult for the submarine crew, especially brentwood escort the pattern was irregular.
On the negative side, zig-zags slow a ship's progress, allowing attackers to overtake more quickly. ISBN Namespaces Article Talk.
