Quoted: I bet it's radar related. Plus if there's even a random low probability of a radar test hurting somebody you know they're going to issue something just as CYA. I've known a couple folks that were working out of there and loved it. They said they also got a lot of good vacation trips jumping on Space A going anywhere. I suppose, I mean different strokes for different folks. There would be some good travel opportunities in that part of the world. I had neighbors who moved in from Gitmo, they actually had Gitmo license plates. They loved it, but they were older, and non-mil. I've had mil friends who had to work at Gitmo, they did not love it. I live in FL and am near the beach. Islands and beaches, while beautiful, don't have as much of an effect on me. I like mountains, I like clean forest (not scrubby FL, S.AL shit), etc. |

Quoted: Not sure if this is sarcasm but given the inverse square law applies to radio waves that would be one hell of a transmitter to be dangerous at 50nm. Like warming up the atmosphere to an obvious and dramatic extent. Either a bs cover for something else, massive ionizing radiation release...which seems unlikely but I don't know what's stored there, or a directed energy test of some type. |

They knew because the guy who didn't turn it off had to pay the bill for that. From someone else entirely who I am 99.9999999% sure was in the navy ... someone on their ship thought they would get a great view and got up the ship and got onto level with the main radar array - one sweep and he was done, DRT. By the time they got up there the body was already red and cooked like a turkey. |

Quoted: Ever get tired of being angry all the time? Quoted: Quoted: what did our "glorious" government fuck up now? Ever get tired of being angry all the time? No, because sometimes, I have some pretty good gallows humor.  Joking and humor aside, I don't know what the future holds. I do know the character of the God who controls it, and believe this: (Romans 8:28) And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose. (Genesis 50:20) As for you, you meant evil against me, but God meant it for good in order to bring about this present result, to preserve many people alive. (Matthew 7:9-11) [9] Or what man is there among you who, when his son asks for a loaf, will give him a stone? [10] Or if he asks for a fish, he will not give him a snake, will he? [11] If you then, being evil, know how to give good gifts to your children, how much more will your Father who is in heaven give what is good to those who ask Him! |

Quoted: https://www.lockheedmartin.com/en-us/products/space-fence.html The World’s Most Advanced Radar In March of 2020 the United States Space Force (USSF) declared operational acceptance and initial operational capability of the Space Fence radar on the Kwajalein Atoll in the Republic of the Marshall Islands. Space Fence, now the world’s most advanced radar, provides uncued detection, tracking and accurate measurement of space objects, including satellites and orbital debris, primarily in low-earth orbit (LEO). The new radar permits the detection of much smaller microsatellites and debris than current systems. It also significantly improves the timeliness with which operators can detect space events. The flexibility and sensitivity of the system also provides coverage of objects in geosynchronous orbit while maintaining the surveillance fence. Before Space Fence, the Space Surveillance Network (SSN) tracked more than 20,000 objects. Now, the catalog size is expected to increase significantly over time. Space Fence also detects closely spaced objects, breakups, maneuvers and launches. According to the Space Force, the system is the most sensitive search radar in the SSN, capable of detecting objects in orbit as small as a marble in low Earth orbit (LEO). https://ieeexplore.ieee.org/document/8712890 This says it's S band (2-4GHz), although to track objects the size of marbles they'd need much higher frequencies. The generally accepted rule of thumb is that a radar can't have usable resolution of objects less than the wavelength of the frequency used... if that's true, they'd need at least 30GHz to resolve 1cm size objects. Enough power to get useful radar returns from space at 30GHz would not be something I would suggest flying through the beam of. It would be a sort of directed energy weapon at closer distances. |

(big-ass, moving radar dishes on things like Carriers and Cruisers.) As opposed to phased-array radars like the SPY-1 flat panels where the beams move, not the antennas. The stuff now has a lot of wattage of radiated power. Megawatts, IIRC. As noted, the irradiated soil vault/concrete dome is on Eniwetak Atoll, a few hundred miles from Kwajalein Atoll. Eniwetak is where things like Ivy Mike, and a bunch of other nukes were set off, not Kwajalein. Though "Kwaj" is where the test Minuteman shots from Vandenberg land, as people like @Limaxray have explained. Bikini Atoll is a different atoll still. Kwajalein Island is the southernmost island of the atoll, with the Bucholtz airfield in question taking up most of it. Thing is, if overflight north of the island is banned, that's pretty much all of the rest of the atoll. (Which is the largest in the World, IIRC. Something like 200 miles or so in circumference.) Agreed, it sounds DEWy. |

By the time they got up there the body was already red and cooked like a turkey. All that to say, yep, if you crawled up in front of an array I suspect you'd get microwaved pretty easily. Some of these navy guys might be able to speak to it, I'm guessing but I'd be shocked if there weren't restrictions on where sailors can be on deck when the SPY-1D is giving full chooch. Even tower climbers on land can get fried by TV towers or radio stations transmitting while they are physically near the transmitter. Now the way this works energy density drops very quickly with distance. Phased arrays can cheat a little because they can beam form, and start off at a much higher effective radiated power (ERP) but the inverse square law still applies. Meaning even a 4MW pencil beam is going to lose a bunch of steam over 20 miles. Plus given the height of the array 20 miles might be just over or at the horizon. Frequencies vary but most ship based radars are high enough frequency that they are line of sight and will punch through the ionosphere rather than bounce and give over the horizon performance, but some do. So a ship 25 miles out landing enough energy on the shore to blow bulbs....doubtful, tied to the pier? maybe. |
I rebuilt one of the Caterpillar 3616 generator engines on Kwaj back in '07. Was there 3 weeks. The walls of the Kwaj Lodge are at least 2' thick concrete, it was storming one morning, didn't hear a thing, saw purple on the weather radar channel, opened the curtains, and it was a whiteout of rain. We went fishing a few times with the locals on weekends, always on the ocean side. Something about don't eat the fish from the lagoon, as if they didn't swim in and out of the lagoon.  We were hand lining wahoo 1/4 mile off shore. Great fishing. The rec center had the absolute biggest record collection I have seen in my life, and about a half dozen record players with headphones. Had a guy walk in there one evening with 2 coconut crabs in a backpack, he picked them up on Roi Namur that day. They put up a hell of a fight, but were delicious.  |

Quoted: Radar operates literally in the microwave range. There are various established bands but one of them is 2.2-2.6 ghz or there abouts. Same as wifi and your kitchen appliance. The modern tico and burke destroyers are passive steerable phased arrays, roughly meaning they can beam form electronically. I'm not sure if official numbers are public but they supposedly can radiate between 4 and 6 million watts ERP as it is very directional. All that to say, yep, if you crawled up in front of an array I suspect you'd get microwaved pretty easily.

I didn’t know much about the place. Another .mil retiree I know was the commander there about a decade ago. We overlapped in a unit about 20-25 years ago without knowing each other. Another colleague I overlapped with and worked with a decent amount between around ‘04 and ‘14 is the commander there now. They are the only two people I know that have ever been stationed ther3. |

My dad flung a lot of stuff at Kwaj One of his more famous launches  ICBM Minuteman I Salvo Launch (24 Feb 1966) - VandenbergAFB, CA (No sound) |

Quoted: Fun fact: John C. Woods, who was the American hangman for the Nuremburg defendents, accidentally electrocuted himself to death while stationed on the Marshall Islands. He lied about his nonexistent extensive experience as an executioner, and botched a whole bunch of those executions (which I'm not going to pretend that I care about). Or... maybe they went exactly as planned... |

They're not quite that powerful. They can put out something in the megawatt range, but there's a lot of nuance to those kinds of figures. |

Quoted: Back in the early 2000's there was scuttlebutt about using the newly developed Upgraded Early Warning Radars (UEWRs) for the Ground Based Midcourse Missile Defense system for "special operations". These are all phased array radars, which means their beams are electronically scanned, essentially no moving parts. Which means it's controlled by software. With new computers replacing 1960's era IBM-360-type hardware - I suppose it's possible to focus the RF energy into a tight beam and do something with it - something interesting. FWIW.
