The Zumwalt looks as if it would roll over in heavy beam seas, but I'm sure the design was tank-tested for that. I read that the "tumblehome" design is supposed to minimize it's radar footprint, but really, a ship two thirds the length of a New Jersey class WWII battleship is going to be pretty easy to spot at sea, from the air, or from a satellite. You forget. Oceans are big. A 600+' ship is a speck from the air or space unless you know exactly where to look for it. It is said that the radar signature of the Zumwalt is about that of a small sailboat. Hi-res satellite photos aren't going to mistake a 600' target for a small sailboat. Oh, and let's not forget the heat bloom from the ship's power plants... 2 Rolls-Royce Marine Trent-30 gas turbines plus 2 Rolls-Royce RR4500 gas turbine generator sets. Easily picked up by satellite or even airborne subhunters. And how about the wakes and ocean turbulence? This is a ship so large it cannot really hide. And even if it were sent to assist in a military mission against an enemy without high tech detection devices, the odds are that enemy has friendly nations with satellites that will supply it with the necessary data. |

Whatever the Navy does, it doesn't have a cloaking device and the ship will be visible. |

It is a platform for stand off weapons designed to hit land targets or sea targets, hundreds of miles away. It is a whole lot cheaper than putting an aircraft carrier out there and risking pilots. Oh, I understand our liking for anonymous warfare fought at a distance. Perhaps some of our enemies will get their hands on standoff weapons, too. It doesn't take a lot of technology these days to launch an exocet like missile 100 miles away from New York City and not care particularly where in the city it lands. I am not sure why you don't love this weapons system. It was conceived during the Clinton Administration (1994) when the US foreign policy was called "Tomahawk Diplomacy". It was perfect for sitting out in the Arabian Sea and lobbing a few million dollar missiles into an aspirin factory in Sudan. (looking for that pesky WMD). Sorry, Mr security guard, you should have called in sick. You are a lot more "doctrinaire" than I am, it seems. But of course...you're a "conservative." Sounds, looks like, Clinton in the Balkans. |

It doesn't take a lot of technology these days to launch an exocet like missile 100 miles away from New York City and not care particularly where in the city it lands. BTW why would you launch an Exocet missile into New York City? I guess you don't know what an Exocet missile really is. (wave top hugging, open water weapon) If someone wanted a couple hundred pound bomb in New York they could just put it in the trunk of a cab and drive it to exactly where they wanted it to go off. The Exocet is not going to be that accurate and it will hit the first building it crosses on land. To be effective they would need to be in the harbor when they shot it. Even then, it might decide a big metal subway sign down near the battery was the most attractive target. harry was lying, to get you to respond. He makes a ridiculous comment like the one above based in nothing but his own fantasy world, and he gets attention. Hell, he doesn't even have to work for it anymore ![]() |

The image has to be downlinked, processed, analyzed and distributed - typically over half an hour at best. By then the ship is somewhere else. |
