Why the Zumwalt-Class Destroyers failed to meet the Navy’s expectations…
OK. They are bigger than they look. 610 feet long.
In January 2019, the Navy (commissioned) its second hi-tech Zumwalt-class stealth destroyer, the USS Michael Monsoor. The third and last, USS Lyndon B. Johnson was launched…December 2018 and will be commissioned in 2022…
…The Zumwalt’s Advanced Gun System didn’t…work that well, with two-thirds the forecast range (around 70 miles). Furthermore, its rocket-boosted LRLAP GPS-guided shells cost $800,000 dollars each—nearly as expensive as more precise, longer-range and harder-hitting cruise missiles. The Navy finally canceled the insanely expensive munitions, leaving the Zumwalt with two huge guns it can’t fire…
What were merely three DDG-1000s good for, despite their nifty stealth features and propulsion? The advanced destroyers lacked ammunition for their guns, anti-ship missiles, anti-submarine torpedoes, and long-range area-air defense missiles. Furthermore, the Zumwalt had fewer cells to pack land-attack missiles than Arleigh-Burke destroyers (96), Ticonderoga-class cruisers (122), or Ohio-class cruise-missile submarines (144)—all of which were cheaper, and the last of which is stealthier.
But, hey, the three only cost US taxpayers $13.5 billion. Chump change for a failed experiment…the way our military is run.

A nurdle is a bead of pure plastic. It is the basic building block of almost all plastic products, like some sort of synthetic ore; their creators call them “pre-production plastic pellets” or “resins.” Every year, trillions of nurdles are produced from natural gas or oil, shipped to factories around the world, and then melted and poured into molds that churn out water bottles and sewage pipes and steering wheels and the millions of other plastic products we use every day. You are almost certainly reading this story on a device that is part nurdle….
An estimated 200,000 metric tons of nurdles make their way into oceans annually. The beads are extremely light, around 20 milligrams each. That means, under current conditions, approximately 10 trillion nurdles are projected to infiltrate marine ecosystems around the world each year.
Hundreds of fish species — including some eaten by humans — and at least 80 kinds of seabirds eat plastics. Researchers are concerned that animals that eat nurdles risk blocking their digestive tracts and starving to death. Just as concerning is what happens to the beads in the long term: Like most plastics, they do not biodegrade, but they do deteriorate over time, forming the second-largest source of ocean microplastics after tire dust. (A nurdle, being less than 5 millimeters around, is a microplastic from the moment of its creation, something also known as a primary microplastic.)
There’s much we still don’t know about how plastics can harm the bodies of humans and animals alike, but recent research has shown that microplastics can be found in the blood of as much as 80 percent of all adult humans, where they can potentially harm our cells. We may not eat the plastic beads ourselves, but nurdles seem to have a way of finding their way back to us.
You could always write to your Congress-critter and complain. If they fit the average profile, they might ask you to explain what a nurdle is. The only reason I know is because I spent a few strange years – long ago and far away – running a production quality lab for a plastics manufacturer. :-]
No doubt, your elected buddy is on the donations payroll from plastic manufacturers who offer a helluva lot more to their re-election than you or I do.
