    In another post, I talked about air superiority. Current doctrine demands that the first targets are enemy airfields. The Migs might get off the ground once, but after that, they will never land again. UCAVs will continue to loiter over the decimated airfields until the end of the war in order to kill any combat engineers.

    As for the current situation with "taliban" or gorilla fighters, UCAVs are perfect. We know the routes we need to follow to get from point A to point B. Convoys get attacked by roadside bombs. Just patrol the highways with UCAVs and scan for anyone digging or any newly-parked cars/trucks/boxes. If the car/truck/box remains for more than 2 hours, blow it up.

    I don't think we've lost any to jamming yet.

    Jamming sites are also ridiculously easy to spot. A few manned aircraft could take it out while the UCAVs loiter. Hell, you could even use a tungsten rod dropped from orbit or a dumb bomb that was lofted from outside of jamming range.

  6. Re:Old hat in the telco world on DC Power Poised To Bring Savings To Datacenters · · Score: 1

    Most systems use sealed lead-acid. Maintenance-free batteries. We do keep thermal probes on the bank and monitor their temps. If a battery gets hot, it's pulled from the bank and replaced; just like RAID. If you've seen a deep-cycle marine battery, then you've seen one cell of a 48VDC bank. We wire 4 batteries into a bank for 48VDC. And we use multiple banks to provide the amperage and amp-hours needed. Most small sites run for 8 to 10 hours. But I have seen massive banks that could be used to operate COs for days with proper power shedding.

  7. Re:This is snake oil on DC Power Poised To Bring Savings To Datacenters · · Score: 1

    I work in one of those facilities. It is a myth that the station runs off the batteries.

    We get 400VAC from commercial. That goes into a 3-way switchbox. The second side of the switchbox is connected to a 400VAC generator. The third part of the box feeds a rectifier. If commercial power fails, the switch kicks over to the generator and the generator starts. A tech has to manually reset the switch to go back to commercial power.

    The output of the rectifier feeds a *huge* copper bar. This bar has several taps that feed DC breaker boxes. The breaker boxes feed the fuse panels at the tops of most of our racks. Some racks are equipped with inverters to get 120VAC back out of the 48VDC.

    At the end of that copper bar, there is a wire connected to a bank of batteries. There is also a ground bar between the rectifier and the battery bank.

    When the station was activated, the rectifiers charged the batteries to 48VDC. After that was done, the breakers were enabled and the station racks are powered off the bus bars.

    In normal operation, the rectifiers and the batteries both power the bus equally. If commercial power stops, the rectifier dies for maybe 30 seconds. At that point, the full load of the station is assumed by the battery bank.

    One other cool note. The battery bank has a hard cutoff and a soft cutoff. The hard cut is an old Frankenstein-esque switch used for maintenance and testing. The soft cut-off hits at 38VDC and shuts down power to save the batteries. You can find "smart" cutoffs that you wire to the rack fuse panels with alarm wire. As the battery bank loses voltage, the cutoff will automatically kill racks with low-priority equipment. Very clever, but I don't trust them.

  8. Re:Not surprising on The Unmanned Air Force · · Score: 4, Insightful

    It's even better than that. The pilot is really only needed on take-off, landing, and to carry out the mission over the target.

    20 pilots can take-off 200 UCAVs, direct them to loiter over the target, and then bring them down in groups of 20 over the target. Finally, they can land the remaining UCAVs at the base.

    While those 200 are en-route, the 20 pilots can be launching or recovering 200 more planes.

    Or, even better, you can set up an assembly line of pilotage. 20 dedicated launchers, 20 dedicated recoverers, 20 dedicated mission specialists. And maybe 5 guys to monitor in-flight information. You could rain constant fire on a target for 24/7*365 with 300 pilots or so.

    And all the pilots would be able to go home at the end of the day.

    *Reaction time for the remote pilot must equal or exceed that of an in-the-air pilot.

    Reaction time does not matter as much in bombing. The UCAV is, more or less, a reusable cruise missile.

    *Data the remote pilot has access to must equal or exceed that of an in-the-air pilot.

    Again, not really needed. One thing that keeps UCAV cost high is the "requirement" to provide feedback to the pilot. Sure, you need basic instruments. But most of the data in the cockpit is really not needed for the remote pilot. An onboard computer can track the data. If it falls outside of parameters, the plane can self-destruct and the pilot can be switched to another plane.

    *Counter-counter measures must ensure that the remote pilot is always in control of the craft.

    It's called an INS. Set up a crypto-enabled link to update the INS in-flight. The INS is a gyroscope attached to a computer and a bomb. If the gyro and the computer disagree, the bomb explodes.

  10. Re:About time. on The Unmanned Air Force · · Score: 5, Insightful

    For years, "fighters" really haven't been doing A2A combat. Most (all?) of these are employed as bombers. And fighter/bombers are limited by airframe, not the pilot.

    And when it comes to bombing, unmanned aircraft are just better. One can orbit at high altitude and lase targets while others come in lower and drop GBUs all over the target. If a few get shot down, no big deal.

    Set up an INS with a gyroscope and trigger that to the proposed flight path and set the bomb to detonate if the plane veers off course. If a few blow up in the air, no big deal. Better than having one go "unguided" and hit whatever.

    Forget calling in air strikes for CAS roles. The soldiers on the front can launch their own RPVs for some stuff. And for other missions, it'll be cost effective to have a wing of escorts accompany the troops. If they are attacked, the UCAVs can come down in seconds and drop munitions.

    Forget the traditional role of air dominance. We can just send hundreds of UCAVs for every piloted vehicle the enemy has. He can't possibly shoot them all down. And in the opening days of the war, we'll blanket all the enemy runways with thousands of UCAVs anyway. Bomb the shit out of the runways and then loiter to take out any combat engineers trying to fix it.

    The greatest thing is the manpower use. One pilot can update the INS for hundreds of UCAVs. Then, they just fly themselves. Once over the target, one pilot can take a single UCAV out of loiter and hit targets all night. Or, 20 pilots can be re-directed to engage in "shock and awe" while their former flights loiter.

    Pilots will be working 8-hour shifts with 15 minute breaks every hour. They will even be able to take lunch. They can do their job from Utah or Maryland or Colorado without every having to deploy to Iraq. They won't have to be in perfect physical shape to fly. Bum knee on a great pilot; no problem.
