US Navy Revives Ancient Navigation


The Naval Academy stopped teaching celestial navigation in the late 1990s, deeming the hard-to-learn skill irrelevant in an era when satellites can relay a ship's location with remarkable ease and precision.

But satellites and GPS are vulnerable to cyber attack. The tools of yesteryear -- sextants, nautical almanacs, volumes of tables -- are not. With that in mind, the academy is reinstating celestial navigation into its curriculum. Wooden boxes with decades-old instruments will be dusted off and opened, and students will once again learn to chart a course by measuring the angles of stars.

As it rebuilds the program, the Navy is getting help from the US Merchant Marine Academy, which never stopped teaching celestial navigation.

    Sort of non-news, since most every other maritime academy still teaches sextant navigation. As far as I know the USGC still has celestial navigation questions on their master's exam as well. You'd be an idiot to pursue any seagoing maritime career and not know how to use a sextant (I'm still learning myself).

    Basically we should be training everybody to reconstruct modern civilization from scratch, starting from everything that's required to build a lathe, because once you have that, everything else kind of falls out naturally.

  3. Nice. Last I knew, the USPS also still taught celestial navigation; partly for this "emergency backup" reason, and I think partly for the "we're a priesthood" reason.

    One of the classic textbooks, "The American Practical Navigator," (usually known by it's author's name "Bowditch"), written in the late 1800s, was based on the premise that if a Navy ship were so injured that a midshipman or senior seaman found himself in charge, he could read this book and figure out how to sail the ship back to port.
