Fleece’s Faves – Apache edition

March 27, 2011

Following the successes of the Ah-1 “Huey” Cobra during the Vietnam War, and the scrapping of the AH-58 Cheyenne attack helicopter program due to the Key West Agreement (a stupid piece of legislation forbidding the US Army from possessing fixed wing assets – the Cheyenne had stub-wings that actually provided lift during level flight, hence it was a “plane” not a chopper), the US Army desiring a reliable and organic anti-armor and close air support asset instituted an Advanced Attack Helicopter competition in which Bell and Boeing Helicopters participated.  The winner of said competition was the Boeing AH-64 Apache.

Armament

We might as well start with its reason for existence, its guns and missiles.  The Apache possesses one potent weapon, hunkering down under her profound nose, the M230 30mm Chain Gun.  Look closely at the picture – a chain gun IS NOT a gatling gun.  Gatling guns are used on aircraft for one purpose only, they have ungodly rates of fire.  A chain gun on the other hand is used for reliability.  Fighter jets’ primary weapon system is their Air to air missiles, they rarely use their guns for air combat, thus rate of fire is preferred and reliability is not so big an issue.  Conversely, an attack chopper’s gun is one of its primary systems, it must work all the time.

A chain gun is pretty cool.  The reason for the cool though enigmatic name (for the uninitiated) is because the bolt is actually operated by a chain that encompasses the whole bolt carrying mechanism.  As the weapon is fired, electrical connections make the chain revolve around the bolt carrier, basically forcing the system to seat and eject rounds as it operates – compared to a gas-fired weapon which uses the basic physics of explosive gas blowback to eject rounds.  The problem with gas operated systems is that they can jam, often forcing the operator to physically remove the jammed cartridge from the weapon before it can be fired again.  Obviously, if one looks at the picture, this would be quite a harrowing task in mid-flight considering the location of the weapon in proximity to the pilots.  Hence, a chain gun is the best solution for maintaining reliability during combat operations.

Enough of that.  The gun fires a 30mm round, which translates to a projectile a little over an inch wide.  This is a big round!  The Apache typically packs 1200 rounds of the M789 HEDP (High-Explosive Dual Purpose) round, capable of penetrating up to 2 inches of Rolled Homogenous Armor or in an anti-personnel application, a lethal radius of 10 feet, pretty impressive.  The gun fires around 300 rounds per minute, though it can max at 625 rpm.  The projectile flies at an awfully slow 800 m/s, rendering the standard effective range at about 1500 meters.

Probably the coolest thing about the gun system and the Apache in general, is how this weapon can be slaved to the pilots helmet system in the cockpit.  Using a monocle in his helmet, the pilot can target this gun simply by moving his head and looking at what he wants to shoot at, the weapon follows his every movement.  How neat is that?  Virtual reality in the 80’s.

Besides the gun, the Apache relies on a bevy of antitank Guided missiles to do its job of anti-armor support – this bird is a tank killer.  Capable of carrying up to 16 AGM-114 Hellfire missiles, a typical combat load reduces this number in half to 8.  The Hellfire is a beast of a missile.  With a warhead of 20 pounds, and a range of over 8000 meters, there are not many tanks on the battlefield that can survive a strike from one of these missiles.

The Hellfire is a laser guided weapon.  This means it “rides” a laser beam from the Apache to the target.  The Apache has a separate targeting system for the Hellfires, called the TADS (Target Acquisition and Designation System).  This is an infrared, low-light Television and laser designating module that sits at the extreme front of the aircraft, operated by the co-pilot who sits front and below the pilot.  The beauty of the Hellfire is that it can use anyone’s laser designation, not just the originating chopper’s.  Thus, a single Apache or Oh-58 Kiowa Scout (a scout chopper commonly couple with Apache wings) can “lase” targets for multiple Hellfire missiles from multiple birds.

The Apache will also frequently equip 70mm Hydra rocket pods.  The 70mm Hydra rocket is an unguided “dumb” rocket used for area attack.  In a covering force role, the Apache will typically equip 38 of these rockets in two pods of 19.

Lastly, depending on the model of the Apache (see Longbow below), the helo can also equip AIM-92 Air to Air Stinger missiles for self-defense from other aircraft.

The Longbow

Besides having a really cool name, the Longbow Apache is a major upgrade over the standard chopper.  The most obvious difference is the bulbous millimeter wave radar dome mounted high above the main rotor.  This dome allows a single Apache, in a hull down position hidden by trees, buildings or a hill, to radar designate up to 128 individual targets at a range up to 8000 meters.  Coupled with the new dome, the Longbow Apaches possess a new digital data system that allows this targeting information to be transferred to other Apaches on the battlefield.  Equipped with an upgraded Longbow Hellfire, a fire and forget millimeter wave guided missile, these targets can quickly and efficiently be dispatched in one fail swoop by any number of birds within range.

Conclusion

No efficient fighting force can rely on an outside asset to efficiently provide the close air support it needs to protect its troops on the ground – the Army understood this and so desired an asset that would do the job.  As with most things the Army develops, the end product was far and away much better than ever considered possible.  The Apache and especially the Longbow Apache, is one of the most deadly anti-armor weapon systems on the planet.

    Apache? I s that a politically correct name for a killing machine? LOL. Thanks so much for the link.

    • March 27, 2011 12:09 pm

      We honor all our helicopters with Native American names, which in reverse is an honor to those peeps as well – though I am sure some whiny bastards out there can find a reason to say its racist or something.

      My pleasure my friend. =)

    Nice bio on the Apache. Sure puts one in the mood to go blow stuff up!

    Thanks for linking.

    Thanks for the link!
    Years ago I worked for a company that worked on defense contracts. We built the shelters that controlled the Patriot missile system as well as the support systems for the Apache. (We built the shelters which housed the radio controls, but did not actually work on the controls themselves) and I used to have a picture that showed the Apache on the ground surrounded by all of the possible armament it could carry. I wish that I still had that picture, but I don’t know where it is.

      I think this may be the picture you had.

      • March 27, 2011 6:31 pm

        Yeah, yours is a lot better, mine is sort of lame, lol.

    • March 27, 2011 6:29 pm

      You are most welcome.

      As far as building the shelters, that’s pretty cool. And for the pic, howabout this?

    Thanks for the link. An awesome machine. We must not have many of those in Afghanistan or that job would have been done years ago.

    • March 28, 2011 4:30 am

      My pleasure. =)

      I am not sure how much air assets we have there, though I am sure we do. In Bosnia, we had quite a few Apaches with us, but that was a different Army, we rolled strong back in the day.

      Snow on opening day? That is just wrong. =(

    Total awesomeness on the Apache article, Fleece! I have always been a fan of the Apache so this was one of the most fun reads I’ve had in a long time… glad you came back with a flourish!

    Thanks for including Questioning…! I just got the motivation back that has been languishing for 3 days now.

    • March 28, 2011 4:15 pm

      I appreciate your kind words about my words. =)

      And I am glad you came back – I definitely know what it is like to struggle with motivation. We all need each other now more than ever, so, including you on my Fave’s list is totally and completely my pleasure. =)

    Thanks for the link Colin. I haven’t been on these last few days because I’ve been on the road traveling back to PA to help my mother. I will post something soon…hopefully.

      No problems my friend, and you are most welcome. =)

      Safe travels.
