who plotted a ship's course in the navy

How does a navigator determine the direction of a ship?

A navigator determines the bearing (the compass direction from the craft's current position) of the next waypoint. Because water currents or wind can cause a craft to drift off course, a navigator sets a course to steer that compensates for drift.

When did navigators start using degrees instead of degrees?

Navigators used ordinal directions, instead of compass degrees, e.g. "northeast" instead of 45° until the mid-20th century when the use of degrees became prevalent. ^ Husick, Charles B. (2009).

What is the 355 class destroyer?

The backbone of the proposed 355 ship U.S. Navy fleet will be the Arleigh Burke class destroyer in its multiple forms. The next generation Arleigh Burke class design, known as the Flight III configuration, borders on an entirely new class. As we mentioned earlier, nearly half the ship has been redesigned. This includes major changes to its hull-form and its superstructure. Many of these changes were made to accommodate the solid-state SPY-6 AMDR radar arrays, which are larger and feature a far denser weight distribution than their predecessors. The ship also features a hybrid-electric drive system and other improvements.

What is the Navy's FFG 7?

One of these critical decisions that seems to have already been made concerns what the Navy plans to do with its mothballed fleet of Oliver Hazard Perry class (FFG-7) frigates. It was originally thought that the Navy could economically upgrade these vessels in a similar fashion as allied nations have, some of which have taken the surplus fighting ships and modernized their combat systems and weaponry. That idea was quickly jettisoned by the Navy's brass. Then the 10 frigates—or the best seven of the lot—were being eyed for regeneration with nearly no upgrades at all. The idea was to deliver them "navigation and radar ready" multi-functional functional platforms.
