Making helicopters just a bit more "stealthy" could pay off in a serious way if you will be well masked much of the time, but know there will be short windows where you are exposed. Even if you aren't out of detection range or undetectable, if you are able to increase detection time, fool radars that discriminate (by making them think you are too small a target to be a helo), or be completely discarded as clutter due to smaller RCS footprint, you can take a lot of risk out of the short periods where you may be exposed. A normal helo may be sporadically detected between masking terrain, which frequently can make helo's impossible or hard to engage, but alerts the hell out air defenses and potentially ground forces if they can figure out where you are going. One that is less observable could, in the best case, not show up in these brief non-masked periods, or could show up as clutter or a spurious track or a questionable track and not alert people in the way that an obviously dropped real helicopter would. edit: regardless, the idea of a helicopter being able to fly across open plains at modern air defenses without being detected is not so realistic. mlmp08 fucked around with this message at 23:14 on May 5, 2011 |

NosmoKing posted:What about the drat NOISE of an approaching helicopter? Well, there are ways to make them far, far quieter and SOCOM has done this and it's not a secret, really. Also, they may be loud, but masked helicopters are very hard to hear because of the hill/mountain/whatever in the way. If you can hear a chopper, it is at VERY close range relative to air defense systems. The only chopper that comes to mind that is distinctly loving loud and has led to me hearing it before I see it is the Huey. That thing "slaps" something fierce. When choppers are flying low, even in a a non-masked environment, you'd be surprised just how close they are before you hear them. A loud two-rotor newschopper hovering overhead gives a weird impression of how far out you hear them compared to a modern military chopper at low level. This link has some info: http://www.globalsecurity.org/military/systems/aircraft/mh-x.htm They're reporting a reduction of 16 dB during flyovers using different rotor designs on an otherwise identical aircraft.

NosmoKing posted:What about the drat NOISE of an approaching helicopter? It's impressive how much of the noise of a helicopter is actually because of the tail rotor. I lived in a place that was trialing one of the MD-500s without the tail rotor (NOTAR) using a ducted fan out the tailboom, and it was way quieter than a regular chopper. I know this because I lived in a bit of a "colourful" area and it would be flying over my neighbourhood fairly often. Getting out of my car then getting hit by their gigantic nightsun flood light without even realizing there was a helicopter right overhead freaked the living bejeesus out of me.

Pretty much this. Remember, LO/"stealth" is not about making you invisible...it is about decreasing the RCS enough to give you some sort of advantage when used in conjunction with other tactics (flying nap of the earth, jamming, etc.), as described above. mlmp08 posted:Well, there are ways to make them far, far quieter and SOCOM has done this and it's not a secret, really.

Back to ending the goddamn world. The Soviets built the Dead Hand system. If they got a signal that there was a nuclear detonation on USSR territory, the (wonderfully reliable) soviet computer system called Moscow. If there was no answer from Da Kremlin, it was assumed that Moscow was a puddle of green glass. Then they launched everything they had in one fell shitfit of nuclear destruction. Oh, goodie. Last I heard, it's still running. Sleep tight, kiddies...

Gun stores in America are filled with high-speed low-drag slippery-from-their-own-blubber "Seals" and Russia is just as equally full of nuts that worked on various "secret projects." But considering the USSR's track record of making reality consistently stranger than fiction, who knows.

Just for everyone jerking off the Bone. The thing costs us a quintillion dollars to feed and run, and the job its doing in Afghanistan is far FAR better done by MQ-9s. They use more fuel on takeoff than every MQ-9 in Afghanistan uses in a week. Also, GPS guided bombs suck dog-dick in this conflict. Some 19 year old JTAC pinned down by a sniper is NOT going to call in reliable grids in any way, and the Bone only breaks contact because a two thousand pounder would make ANY insurgent run away. I guess if anyone had questions on RPA usage in our current wars, I could lend a little bit of insight...

Two others come to mind: the Sea King and the Chinook. Sea Kings are just ridiculously loud in any possible way, like a persistent ships horn as an encouragement to shipbroken sailors. It's unbelievable. The Chinook on the other hand has this weird thud-thud-thud sound that's really distinct. Rotor design is heavy poo poo. Dead Hand is kinda sinister, but there's still an element of human control in the decision loop. It's amazing that the Russians have given out any information about it at all considering how hermetically sealed their archives usually are.

Well worth a read. That was indeed very interesting. I remember reading about special blade tip geometry for reducing blade-vortex interactions... Here it is, it was called Blue Edge: https://www.youtube.com/watch?v=dBS1NRsYuF8 As well as being quieter it loses a lot of that distinctive thwacking sound. I guess there's only so much you can do to mitigate the acoustic signature of a helicopter though. The Comanche had a ducted fan for a tail rotor and a 5-blade main rotor which would certainly help.

It's not like most air defense units just sit around radiating 24/7 with missiles ready to fire, even in Pakistan. I don't know if there are SAMs around the military academy in Abbattobad (sp?). mlmp08 fucked around with this message at 15:40 on May 6, 2011 |

I would imagine the bulk of Pakistan's air defenses are gathered on the borders it shares with India. They're undoubtedly a lot more concerned about an attack by air from the Indian Air Force than they are the Afghan one, or from the American one in Afghanistan for that matter.

Dont MANPADS have a major drawback in regards to target aquisition and identification in that you're basically depending on the operator to not fire on friendly helicopters?

Yes but that's also a problem with most missiles. If my memory serves me when India was invited to Red Flag half of their losses were due to friendly fire, their command and control has a ways to go. Friend or foe identification is still a huge issue as well.

US MANPADS has an IFF transponder, but it's also possible for a gunner to "miss" with the IFF and get no response when there really ought to be one. Doctrinally, you will IFF all targets before engaging, but if it's a fast FW aircraft or a late detection RW target, the operator may have to rely on visual ID in order to engage before the target escapes or engages friendly forces. It has been my experience working with Marine MANPADS units that fratricides are a serious concern, in that they tend to shoot down one of their own at each WTI course.

daskrolator posted:Yes but that's also a problem with most missiles. The ratio of friendly-fire losses to total losses may be a bad metric, since it can be distorted by a low rate of losses due to enemy action. What was their ratio of friendly-fire kills to total kills? I think both of these ratios must be considered to answer whether the force in question is more solution or problem.

Honestly, If the seals didn't have enough time to destroy the rest of that stealth helicopter, why couldn't the military have hit it with a missile strike from a drone? I can't believe there were no drones in the area.
