Can someone please tell me why the greatest Military power in the world can't stop a simple basic RPG? I'm very upset again that many of our brave special forces have been lost to this same scenario. I'm not sure what they are called but the bar armor on tanks and MRAP's, why can't we adapt them onto the Chinook's sides, back and bottom of the aircraft. I know the weight will increase but it's gonna stop.

Gonna put it on the rotor assembly, too?

ETA:  You might want to talk to the Russians regarding their experiences with armored helicopters in Afghanistan.

Yeah, that place was a freakin graveyard for HIND's.

Helicopters are an inherantly vulnerable platform, who's mechanical nature makes them very sensitive to damage. Until somebody can poop us ducted turbines that work worth a damn, or anti-gravity, they are pretty much what weve got.

I'm not an engineer, but I'm gonna go with...

Those things barely fly as is, any more weight and they wouldn't be able to take any cargo.

Personally I think we'd be better off to use multiple black hawks which are a smaller target and if they do get taken out were only looking at 12-15 guys instead of 35+

You know why the Chinook aint armored up against RPGs?

Because the rotors would peel off on overpasses.

The CH-47 Chinook along with other U.S. Army aircraft do have ballistic armor installed in them.  They are attached to the floor in the cabin and in the cockpit to protect against small arms fire.  When I was in Taji, Iraq in 2005 we lost an Apache due to an RPG and killing both crew members.  It doesn't take much to take down a helicopter.

The problem with that idea is altitude, Chinooks are better in the mountains, like Afghanistan, than the Blackhawk. That is why they were using one instead of Blackhawks.

OP, your armored Chinook might fly at sea level, but it wouldn't have enough power to take off in Afghanistan. A whiz-bang laser anti-missile system would work, if we could invent one small enough and powerful enough that could withstand the rigors of being on a flying eggbeater.

The RPG shaped charge warhead can penetrate around 100mm of hard steel armor.  No aircraft in the world can defeat that warhead, and most main battle tanks have a hard time with them.

Not to mention power considerations.

There is very little that can be done to stop RPGs, There have been a bunch of threads on this in the past few days. I feel like a lot of you don't understand just how power limited helicopters are in general, not to mention in Afghanistan.
I can only speak for the one I fly, but I'll tell you with a full load we BARELY get off of the ground in the US! Armor is simply out of the question.

 Optimally,each MH-6 could carry 6 troops,but realistically it's 4. Except in Afghanistan where they can't because it's too high,too hot and the Little Birds don't have enough power so let's pretend that they actually could fly all over the Hindu Kush with 2 ( except they can't...). You're going to need 15 of them to equal a Chinook.

The armor installed on U.S. Army aircraft can stop 7.62 X 39.  A Blackhawk flew into a hostile area in Baghdad and took some fire from 7.62 X 39 and it stopped the rounds from penetrating the belly of the cabin.

And as far as IED's go, these motherfuckers are creative.

they can turn literally ANYTHING into an IED, and any time we come up with counter measures, they have a way to defeat it inside a couple months.

You are very correct in saying that the armor does not protect against everything.  In that same aircraft the co-pilot had a round pass between the side and back armor on his seat and passed through his body armor and then proceeded to pass through one of his lungs then through the body armor on his front side then take out the windscreen.  I was told it was at least a .50 caliber round that did that though.  I inspected the aircraft and the armor did a good job of stopping the other rounds fired at it.

  They just  have a shit-ton more RPGs than MANPADs. First of all,there really weren't all that many delivered 20+ years ago and those that have been left have been subject to battery expiration and general abuse to render them unservicible,practice,sent to other places ( a couple Stingers were used to shoot down Russian planes in Chechnya,funneled over by Iran or Pakistan most likely). If there were bunches of them there,plenty more aircraft would have been shot down by the ones left functioning.
 If you take a look at the rebels in Libya,there are a shitload of SA-7's and 14's around and they apparently will shoot 'em off as fancy rockets in the general direction of "over there",suspect plenty were used that way in Afghanistan.

Sometimes a David can beat a Goliath.  It's war.  It happens.  Think of all the men killed every time a ship sunk during WWII by something as stupid as a floating mine.  Or the entire fleets of bombers shot down by blinding shooting exploding shells into the air.  If that round or RPG or mine or IED or rocket or missile or falling piano has your name on it, that's just the way it is.  Gasping louding and grabbing your chest demanding that armor be added or whatever else is a typical knee-jerk reaction that will just result in more casualties.  Put more armor on a helo?  Make it a beast that can barely take off in thin air?  Awesome?  Reduce the amount of troops it can carry?  Brilliant!  Make it half as fast?  Thanks Howard Hughes.  So now we have a helo that can barely take off and has to leave half the amount of people on the ground while it takes twice as long to bring back more troops.  Sounds like a game plan to me.

MH-6 max speed - 152 knots. Carrying troops externally much less.

UH-60 max speed 159 knots

AH-64 Max speed 159 knots

The Chinook its not "lumbering" by any means. It is actually very fast, and in capable hands very nimble.


When a Chinook is escorted by Apaches it has to slow down to the Apache's speed of 120 knots when they are fully armored.

Exactly.  Everything on an airplane or helicopter is a tradeoff.  Even if you were willing to give up 100lbs of fuel to add 100lbs of armor, you'd soon find out that new armor throws off your CG and requires adding another 20lbs in the nose of the helicopter, which means you need to lose another 20lbs of fuel.  Oh, and btw that extra weight in the nose reduces your directional control which means you have less ability to fly in a crosswind.  Or you can increase the effectiveness of the tail rotor which takes more power from the main rotor and now you need to reduce weight again.

I'm just pulling all this out of my ass but these are the sort of tradeoffs you have to deal with.  For some missions, they may be worth it, but usually not.  And any seemingly minor change is amplified in a situatuion like Afghanistan where you arr operating at or beyond the limits of your aircraft.
