I'm sure you'll give a cite for that, Fred, but since I know about the Huey kill of the AN-2, I'll share first: "It Happened To Me by Walt Darran as told to M.L. Jones SOF Contributing Aviation Editor Walt Darran. who flew Navy fighter planes from 1961-67 and piloted Air America and Continental Air Services cargo planes from 1967-69, was present in Laos when (for the only time in aviation history) a helicopter shot down a fixed- wing aircraft - indeed, two of them. The victims were two Polish-built PZL Mielex Antonov AN-2 biplanes, known as Colts, of the North Vietnamese Air Force. The victor was an Air America Huey whose only armament was an AK-47 assault rifle. As Darran tells it: On 12 January 1968, an Air America Huey was delivering 105mm ammo from a U.S. TACAN (navigational aids) station perched on a high pinnacle deep in northern Laos to some artillery positions down below. I was flying a Continental Air Services Pilatus Porter (a single-engine turboprop transport capable of short landings and takeoffs) making some rice drops in the area at the time. I had just headed back for LS36 (a Royal Laotian Army base) to refuel when the choppcr pilot, Ted Moore, screamed over the radio that two Colts were strafing and bombing the artillery positions. We were the only ones in VHF radio contact with one another at the time and since I was higher, I transmitted the message to CROWN (an orbiting C-130 with powerful radio equipment capable of relaying messages from Laos and Vietnam to U.S. 7th Fleet aircraft carriers) for fighters, all the while ****ed as hell that I was almost out of fuel. I was familiar with the Colt. When I was in the Navy, they'd send us out on "Dawn Patrols," looking for the. rascals. They were used for aerial drops to isolated outposts, usually right at dawn in order to avoid visual sightings. To the best of my knowledge, the military never got one. Nor did they this time, despite the fact that all kinds of fighters were scrambled and sent to the area. By the time they got there, it was all over. I heard Ted say, "****, I'm faster and can outmaneuver them." So off the Huey went in pursuit. Glen Wood, the flight mechanic, had an AK-47 and shot the *******s down while the Huey made a few passes. One went down near the scene and the other pancaked into a hill it couldn't outclimb, about 13 miles away. I had to go to Vientiane the next day, so I missed getting any of the real goodies like Russian pistols, watches and so forth that were distributed when a Chinook brought one of the wrecks into LS36. One of the guys did manage to save me some of the canvas from the only fixed-wing aircraft ever shot down by a chopper." Cited from: http://limasite85.us/ann_holland_page_2.htm If you consider "Soldier of Fortune" to be a somewhat untrustworthy source, there are plenty of others describing the events. Here's another, slightly differing in the details: http://home.hiwaay.net/~jlwebs/misc.html and a third, ditto: http://www.cia.gov/csi/studies/95unclass/Linder.html Okay, your turn to tell us all about the the stealth fighter that was shot down with a handgun;-) :using a door gun while flying co-speed and arallel to a UAV should be doable, given that they can get a lot closer than :any fighter without needing to take avoiding action (owing to much lower -- :zero under ideal conditions -- closure rates. A UAV is a smaller target, but :likely able to take less violent avoiding action. Put a lead-computing :sight on the MG and it's easier, or just load it with lots of tracer. epending on how close they're willing to get (mainly a question of how :violently the UAV is or might be maneuvering), instead of an LCOSS they might :be able to get away with a simple laser sight. Alternatively, forward-firing :rockets with prox. fuses may do the trick, at relatively low cost. Why go to all this trouble? Use the bloody system that is already designed to deal with air vehicles. Because, as Paul has pointed out, it's fairly poorly suited to dealing with this particular type of target. Doesn't mean it could never do the job, but it's an inefficient use of resources. Larger UAVs are a different matter. Guy SAAF also claims a door gunner kill against a Zimbabwe? Defender. There are likely to be other accounts as well. Of course the ratio of fixed vs rotary in not in the Helo's favor Pain |

No, thamks, I prefer goldy or silvery - higher resale values. :"Hint: Helicopters aren't used as interceptors." - unless the contact :is low and slow, like many types of UAV, in which case helicopters *are* :used as interceptors. No, they aren't. Interceptors carry WEAPONS, Paul. Helicopters carry WEAPONS, Fred. http://en.wikipedia.org/wiki/Image:GAU-16_.50_MG.jpg is a nice example of the US version: http://www.royal-navy.mod.uk/server/...MediaFile.6900 shows a Lynx with two Skua and a M3M. Gee, not so wrong after all, I guess. Right - naval helicopters don't do aerial intercepts, except that they do. They're unarmed apart from their weapons. What is Fred going to amaze us with next? :What air-to-air weapons do you think a USN SH-60 carries? : :For this, the optional door gun should suffice nicely (that's what the :Lynx would be using, after all). So you think a guy standing in a doorway over iron sights using a weapon never intended to fire at anything but the ground is going to hit one of these things but a purpose built machine designed to take on air targets is going to be unable to? Certainly could, Fred. See, instead of coming in at ~150 knots of overtake, trying to hit a one-foot-diameter target with a fixed gun whose sights aren't registering the target properly, in a helicopter you can pull up alongside for a leisurely shoot at zero relative velocity, with no rush and no hurry. Now, you may claim US machine gunners may be unable to hit a four-foot by one foot target (ScanEagle from the side) from, say, fifty metres (let's give them a decent standoff distance in case the UAV does something unpredictable) but if you're right then the RN can give them some lessons. (Personally I think you're wrong yet again, but we'll see). (Oh, and who told you that the MGs only had iron sights? Or that they were ineffective for anything other than ground fire?) You've got an extraordinarily ill-tempered manner of saying "I was wrong". -- Paul J. Adam |

Radio direction finding may permit the location of its headquarters to be found. Good point, few countries have enough satellite bandwidth to manage UAVs the way the US does, so unless Iran is buying bandwidth from someone else, they'd have to be RC controlled UAVs. Fully autonomous UAVs are not common today---but they probably will be in another few years. They would be particularly good for surveillance of large targets like a CVBG. The UAV could send out data and wait for very generic microburst commands like "circle left, 20mile radius". That would make it hard to attack the controller. While it may be possible get a DF location on a randomly-timed, 10millisecond, spread spectrum signal from a mobile command post, it might also be very expensive. And, you'd have to be looking for it. There is a lot of spectrum to monitor. John Mullen The Navy does spend money on things other than $800 toilet seats. |

In the AA mode that uses radar aiming and proximity fuzes, and I'm not sure if either would be sensitive enough to respond to a small stealthy UAV. I would have thought that the 3Ps range gate fusing would be ideal for that ? A UAV with a spinning propellor is not going to be overly stealthy, hard to see yes, invisible to radar ? What makes you think UAVs are restricted to props for propulsion? Pain Can you give a cite for a ramjet model? Also, could you please cite a role for a ramjet powered UAV (other than a harpoon/tomahawk - I suppose they could be considered UAVs). I suppose one of the reasons is the role these UAVs have at the moment. One of their biggest advantages is their loiter time. You get the best loiter times with a low power prop driven a/c. Also, speed is not a necessity for recon - unless you are trying to out run an adversary. Lastly, UAVs are expendable and prop driven aircraft are relatively cheap. I keep hearing about how UAVs are going to take out a carrier. How the hell much explosive can one of these craft carry? Also, if there is not some sort of penetrator nose on the thing (more weight), the best it can do is superficial damage to just about any vessel. I daresay, the most payload one of these things can carry is about 25lbs. I really have no expertise in this area, I am just speculating based on my conjecture. Mark |
