I think almost everyone is missing the point about assymetric warfare. All the comments are based on US/NATO type equipment standards, and military objectives. The whole point of assymetric warfare is that you don't follow the standards, you go for what you can achieve where you can achieve it with what you can get. 9/11 was a classic example. If some one out there is planning on using cruise missiles for example, he wont build them to Tomahawk standards, he wont select tomahawk like targets and so on. Assymetric warfare is about doing the unexpected, with the unexpected by surprise, that negates the defences and allows success. If you haven't got the budget of the US, you dont try to emulate them and expect to win, you have to think out of 'our' box. Brings to mind the VC etc. use of 122mm and 240mm rockets as short range boosters for oil drums, etc. filled with explosives. The new variant is the Improvised Explosive Device, in this case the delivery system comes to you in the form of patrols. Just saw a refernce to 600,000 tons of explosives in Iraq: "There is approximately 600,000 tons of ordnance out on the ground throughout the country," said Army Maj. Adam Boyd, of the 1138th Mine, Explosive and Ordnance Information Coordination Center, "and the enemy is getting smarter every single day on how to use it." |

(Solution - go to spread spectrum). Indeed. Then you need to use relatively high frequencies, and your radio navigation system will be line-of-sight only. This then means you need lots of closely-spaced transmitters, especially if you want to be able to navigate while flying at low altitude. I'd still rate a radio location system using spread spectrum transmitters as rather vulnerable, because the transmitters have to remain in a fixed location for the system to work, and would be prime targets. What if most of the transimtters are turned off most of the time? If there are fake transmitters, there to soak up hits, and (hopefully) entice enemy aircraft to put themselves in danger? Then your radio navigation system has gotten a lot more complicated. You can't just set up transmitters at arbitrary locations broadcasting at arbitrary times -- to work, a radio navigation system needs known transmitters at precisely known locations. Say 80 percent of your transmitters are turned off at any one time. Then you need five times as many transmitters in total, so that you can get complete coverage in the area where you want to navigate with only 20 percent of them. If you set up fake transmitters to attract attention away from the real ones, you also need to somehow avoid spoofing your own weapons. It would kind of suck if all of your HLCCMs flew off to the wrong place because they were navigating using signals from a fake transmitter. ljd |

A civilian is making a cruise missile in his garage in New Zealand for less then 5000 dollars. No, he's built, but not flown one prototype thats pretty much an engine and crude guidance. I dont have the web site but from memory it has a range of 500k (?), accurate to about 10m (uses GPS which of course is not secure in a war zone) and sends live TV feed back to base. It's range, accuracy, and performance are unknown, the prototype has never actually flown. The systems have never been integrated.

If the software was written right, it could probably be done with several orders of magnitude more efficiency. What competing method is there except for Open Source? Open source -- or rather, using some of the ideas from how OSS projects are btypically run -- is certainly useful. The reason for my question is that I don't think Open Source is very applicable the type of 'sharp edge' military systems you are talking about here. It is very applicable to making programs that help you make sure that every regiment gets the correct number of socks and ammo, but not to making program that handles guidance and target discrimination routines. Especially not if you expect your capabilities to remain anything like secret.

It's hard to penetrate with traffic analysis, yes. However a station transmitting 24/7 is a station that's easily located, and a station that will eat a gross of ordinance at H hour + .01 second. So everyobody goes on red alert as soon as the primary station stops broadcasting, and the targetting information has to be sent by the second backup station. And then the secondary system gets targeted PDQ... To anticipate some objections, yes, if you get all the backup stations, you will prevent the sending of the targeting information (as well as any other sort of C&C activity). You and Phil, and to a lesser extent George, who should know better, don't seem to realize that killing the enemy C&C is how the US fights wars today.
