    Fair Winds and Following Seas

    Named for a brilliant and controversial admiral, the newly christened
    USS Zumwalt is the Navy’s most advanced ship.


    It will be interesting to see how she fairs. Hopefully she will be proven before she gets into a fight.

    Two weeks ago, the Navy’s most technologically advanced ship, a 15,000-ton guided-missile destroyer, was commissioned in Baltimore. The USS Zumwalt looks more like a spaceship than a traditional Navy ship, and is both twice the size and cost of the Navy’s mainstay destroyers, the Arleigh Burke class. In a strange twist, the Zumwalt’s first commanding officer is Captain James “T.” Kirk. It’s a fitting ship for the twenty-first century.


    The Zumwalt is as radical in design as the man she is named after. Designed to be stealthy, the 610-foot ship features an all-electric propulsion system, tumblehome (backward-slanting) bow, uncluttered deck, and superstructure presenting a radar image that mimics a 50-foot fishing boat. Her futuristic weapons systems include lasers, missiles, and—eventually—an electromagnetic railgun that can fire 23-pound projectiles at speeds of Mach 7 without using gunpowder.




    The Zumwalt—like the admiral—is controversial. The cost of this lead-in-class vessel soared to $4.3 billion from an initial estimate of $1.4 billion. The cost overruns led Congress and the Navy to scrap plans for 32 ships in the class to just three. “There is just too much new technology in one package,” says retired Navy captain Jerry Hendrix, a senior fellow at the Center for New American Security. “The newly designed electrical propulsion system has delayed construction and the electromagnetic railgun is not ready for the first two ships. None of these improvements are bad by themselves, but all together they posed a bridge too far.”

    Rising Seas Threaten Military installations...

    Military Leaders Respond as Rising Seas Threaten Installations
    6 Aug.`18 - Former military leaders gather Tuesday at a conference on sea level rise and security at The Citadel.
    Military leaders in South Carolina are preparing for rising sea levels while partisans dispute whether it's the effect of global warming. The Post and Courier of Charleston reports the Marine Corps training grounds on Parris Island need a sea wall, roads near Charleston's Coast Guard stations are swamped when heavy rain adds to high tides and stone reinforcements were installed to protect a runway from erosion at the Marine Corp Air Station in Beaufort.




    U.S. Marine Corps recruits with Platoon 4038, Papa Company, 4th Recruit Training Battalion, near the finish line of the run portion of their Initial Strength Test on Parris Island July 20, 2018.




    Former military leaders gather Tuesday at a conference on sea level rise and security at The Citadel. Retired Marine Brig. Gen. Stephen Cheney is one conference speaker. The former commander of the Parris Island Recruit Depots says encroaching oceans could limit the ability to move troops or armaments, train for warfare or even staff bases.

    Is Jakarta the new Venice?...

    Jakarta, the fastest-sinking city in the world
    • 13 August 2018 - The Indonesian capital of Jakarta is home to 10 million people but it is also one of the fastest-sinking cities in the world. If this goes unchecked, parts of the megacity could be entirely submerged by 2050, say researchers. Is it too late?

      It sits on swampy land, the Java Sea lapping against it, and 13 rivers running through it. So it shouldn't be a surprise that flooding is frequent in Jakarta and, according to experts, it is getting worse. But it's not just about freak floods, this massive city is literally disappearing into the ground. "The potential for Jakarta to be submerged isn't a laughing matter," says Heri Andreas, who has studied Jakarta's land subsidence for the past 20 years at the Bandung Institute of Technology. "If we look at our models, by 2050 about 95% of North Jakarta will be submerged."

    North Jakarta is sinking by about 25cm every year




    It's already happening - North Jakarta has sunk 2.5m in 10 years and is continuing to sink by as much as 25cm a year in some parts, which is more than double the global average for coastal megacities. Jakarta is sinking by an average of 1-15cm a year and almost half the city now sits below sea level. The impact is immediately apparent in North Jakarta. In the district of Muara Baru, an entire office building lies abandoned. It once housed a fishing company but the first-floor veranda is the only functional part left.



    Stagnant water on the ground floor





    The submerged ground floor is full of stagnant floodwater. The land around it is higher so the water has nowhere to go. Buildings that are so deeply sunk are rarely abandoned like this, because most of the time the owners will try to fix, rebuild and find short-term remedies for the issue. But what they can't do is stop the soil sucking this part of the city down.




    The sea wall is meant to mitigate the city's severe flooding




    An open air fish market is just a five-minute drive away. "The walkways are like waves, curving up and down, people can trip and fall," says Ridwan, a Muara Baru resident who often visits the fish market. As the water levels underground are being depleted, the very ground market-goers walk on is sinking and shifting, creating an uneven and unstable surface. "Year after year, the ground has just kept sinking," he said, just one of many inhabitants of this quarter alarmed at what is happening to the neighbourhood.

    Zumwalt would have tweeted just as President Trump does.
    Call your state legislators and insist they approve the Article V convention of States to propose amendments.

    It is time to move the city elsewhere.
