The Apache – Destroy, Disrupt, Delay

The Apache - Destroy, Disrupt, Delay

The Boeing (McDonnell Douglas) (formerly Hughes) AH-64A Apache is the Army’s primary attack helicopter.

It is a quick-reacting, airborne weapon system that can fight close and deep to destroy, disrupt, or delay enemy forces.

The Apache is designed to fight and survive during the day, night, and in adverse weather throughout the world.

The principal mission of the Apache is the destruction of high-value targets with the HELLFIRE missile.

It is also capable of employing a 30MM M230 chain gun and Hydra 70 (2.75 inch) rockets that are lethal against a wide variety of targets. The Apache has a full range of aircraft survivability equipment and has the ability to withstand hits from rounds up to 23MM in critical areas.

The AH-64 Apache is a twin-engine, four bladed, multi-mission attack helicopter designed as a highly stable aerial weapons-delivery platform. It is designed to fight and survive during the day, night, and in adverse weather throughout the world.

With a tandem-seated crew consisting of the pilot, located in the rear cockpit position and the co-pilot gunner (CPG), located in the front position, the Apache is self-deployable, highly survivable and delivers a lethal array of battlefield armaments.

The Apache features a Target Acquisition Designation Sight (TADS) and a Pilot Night Vision Sensor (PNVS) which enables the crew to navigate and conduct precision attacks in day, night and adverse weather conditions.

The Apache can carry up to 16 Hellfire laser designated missiles.

With a range of over 8000 meters, the Hellfire is used primarily for the destruction of tanks, armored vehicles and other hard material targets.

The Apache can also deliver 76, 2.75" folding fin aerial rockets for use against enemy personnel, light armor vehicles and other soft-skinned targets.

Rounding out the Apache’s deadly punch are 1,200 rounds of ammunition for its Area Weapons System (AWS), 30MM Automatic Gun.

Powered by two General Electric gas turbine engines rated at 1890 shaft horsepower each, the Apache’s maximum gross weight is 17,650 pounds which allows for a cruise airspeed of 145 miles per hour and a flight endurance of over three hours.

The AH-64 can be configured with an external 230-gallon fuel tank to extend its range on attack missions, or it can be configured with up to four 230-gallon fuel tanks for ferrying/self-deployment missions.

The combat radius of the AH-64 is approximately 150 kilometers.

The combat radius with one external 230-gallon fuel tank installed is approximately 300 kilometers [radii are temperature, PA, fuel burn rate and airspeed dependent]. The AH-64 is air transportable in the C-5, C-141 and C-17.

An on-board video recorder has the capability of recording up to 72 minutes of either the pilot or CPG selected video. It is an invaluable tool for damage assessment and reconnaissance.

The Apache’s navigation equipment consists of a doppler navigation system, and most aircraft are equipped with a GPS receiver.

The Apache has state of the art optics that provide the capability to select from three different target acquisition sensors. These sensors are

* Day TV. Views images during day and low light levels, black and white.
* TADS FLIR. Views thermal images, real world and magnified, during day, night and adverse weather.
* DVO. Views real world, full color, and magnified images during daylight and dusk conditions. >

The Apache has four articulating weapons pylons, two on either side of the aircraft, on which weapons or external fuel tanks can be mounted. The aircraft has a LRF/D.

This is used to designate for the Hellfire missile system as well as provide range to target information for the fire control computer’s calculations of ballistic solutions. Threat identification through the FLIR system is extremely difficult.

Although the AH-64 crew can easily find the heat signature of a vehicle, it may not be able to determine friend or foe.

Forward looking infrared detects the difference in the emission of heat in objects. On a hot day, the ground may reflect or emit more heat than the suspected target.

In this case, the environment will be "hot" and the target will be "cool".

As the air cools at night, the target may lose or emit heat at a lower rate than the surrounding environment.

At some point the emission of heat from both the target and the surrounding environment may be equal.

This is IR crossover and makes target acquisition/detection difficult to impossible.

IR crossover occurs most often when the environment is wet.

This is because the water in the air creates a buffer in the emissivity of objects. This limitation is present in all systems that use FLIR for target acquisition.

Low cloud ceilings may not allow the Hellfire seeker enough time to lock onto its target or may cause it to break lock after acquisition.

At extended ranges, the pilot may have to consider the ceiling to allow time for the seeker to steer the weapon onto the target.

Pilot night vision sensor cannot detect wires or other small obstacles.

Overwater operations severely degrade navigation systems not upgraded with embedded GPS.

Although fully capable of operating in marginal weather, attack helicopter capabilities are seriously degraded in conditions below a 500-foot ceiling and visibility less than 3 km.

Because of the Hellfire missile’s trajectory, ceilings below 500 feet require the attack aircraft to get too close to the intended target to avoid missile loss.

Below 3 km visibility, the attack aircraft is vulnerable to enemy ADA systems.

Some obscurants can prevent the laser energy from reaching the target; they can also hide the target from the incoming munitions seeker.

Dust, haze, rain, snow and other particulate matter may limit visibility and affect sensors.

The Hellfire remote designating crew may offset a maximum of 60 degrees from the gun to target line and must not position their aircraft within a +30-degree safety fan from the firing aircraft.

The Apache fully exploits the vertical dimension of the battlefield. Aggressive terrain flight techniques allow the commander to rapidly place the ATKHB at the decisive place at the optimum time. Typically, the area of operations for Apache is the entire corps or divisional sector.

Attack helicopters move across the battlefield at speeds in excess of 3 kilometers per minute.

Typical planning airspeeds are 100 to 120 knots during daylight and 80 to 100 knots at night.

Speeds during marginal weather are reduced commensurate with prevailing conditions.

The Apache can attack targets up to 150 km across the FLOT.

If greater depth is required, the addition of ERFS tanks can further extend the AH-64’s range with a corresponding reduction in Hellfire missile carrying capacity (four fewer Hellfire missiles for each ERFS tank installed).

Apache production began in FY82 and the first unit was deployed in FY86. As of November 1993, 807 Apaches were delivered to the Army.

The last Army Apache delivery is scheduled for December 1995.

Thirty-three attack battalions are deployed and ready for combat.

The Army is procuring a total of 824 Apaches to support a new force structure of 25 battalions with 24 Apaches for each unit (16 Active; 2 Reserve; 7 National Guard) under the Aviation Restructure Initiative.

The Apache has been sold to Israel, Egypt, Saudi Arabia, the UAE, and Greece.

The Russian-developed Mi-24 HIND is the Apache’s closest couterpart.

The Russians have deployed significant numbers of HINDs in Europe and have exported the HIND to many third world countries.

The Russians have also developed the KA-50 HOKUM as their next generation attack helicopter.

The Italian A-129 Mangusta is the nearest NATO counterpart to the Apache.

The Germans and French are co-developing the PAH-2 Tiger attack helicopter, which has many of the capabilities of the Apache.

Curiosity AI – Artificial Intelligence in Virtual Worlds

Curiosity AI - Artificial Intelligence in Virtual Worlds

Flickr only shows a short clip… see the video in its entirety here: or here:


Humankind has often wondered, “Is there intelligent life beyond Earth?” With the recent Augustine Report findings and the New NASA Plan that stresses unmanned exploration, the demand and use of humanlike and non-humanlike machines to be the robotic explorers in our solar system and beyond has become increasingly important. Robotic explorers, both humanlike and non-humanlike in appearance, can reduce the danger to humans by gathering environmental data and sending that data back to Earth for detailed analysis. Perhaps of greatest importance, AI robotic explorers have the potential to serve as “intelligent assistants” to aid those working in “the field.” These hypothetical scenarios are modeled in the virtual world Second Life project “Curiosity AI.” In particular, the ability of AI machines to control other machines; to sense, transmit and remember environmental data; and to perform tasks in groups are explored.


In a presentation given by Tara Estlin, one of NASA’s Artificial Intelligence programmers whose work has been useful for several Mars rovers, one of the problems identified is the need for In-Situ data analysis. Data transmitted by the rovers only has a certain window of dish time when transmitting to the DSN receivers on Earth, so reducing the amount of data sent to only the most relevant is an important goal. The ability for an AI to summarize data therefore would be an asset. This demonstration shows Curiosity Scientist delegating to the rover a request to the Phoenix lander—to calculate and report the sum the first 20 readings of atmospheric pressure data for day 5 of the Phoenix mission. One way this type of in-situ analysis could be used is to detect extreme pressure drops which may be a sign of dust devils. If these spontaneous dust devils were detected, more than one robot could be coordinated so as to record these interesting phenomena while they are occurring.


The simulated Mars Embla is an example of an expert machine. AI can be used to identify other AI and delegate responsibility to a machine with a specific expert capability, perhaps one that it lacks itself, like the previous example. One of the possibilities for future systems is an expectation that AI may serve as emissary exchange agents for collection and routing of other AI queries. This type of cooperative behavior allows communication with each other and the coordination of behavior to jointly accomplish tasks. In Second Life one way this can be accomplished is by programming robots to listen for certain commands while others ignore them. Another way is to program robots to only listen to certain AI agents, and ignore all other agents. In real life, the Curiosity rover is limited by its size, speed, and need to travel along a sometimes difficult terrain. In this simulation, Curiosity Scientist tells the rover to launch the Mars Embla swarm. The Mars Embla, modeled on the actual Embla, is small, travels much faster than the rover (50 mph compared to .6 mph), and hovers above the ground capable of flying up to 10,000 feet (which is above Mars’ dust devils). The Embla swarms quickly spread out to cover a lot of territory. The swarms are programmed to maintain a certain distance from each other. The swarms might be used to return simultaneous, multi-location readings back to Curiosity Scientist. In this case they are temperature readings, but they could be any type of readings or video capability for which the Embla is equipped. These readings might then be processed by Curiosity Scientist for in-situ analysis.


Generally, the capabilities of AI agents can help people better manage “information overload” and to interact with data on a more “human” level. That is, an AI should be able to navigate the information superhighway reducing the information flow to meet the requester’s needs, communicate in natural language, and generate an emotional response. This attempt for computers to have a human-like response, was made famous by Alan Turing in 1950. So where is AI today? What’s beginning to occur is a paradigm shift from software-as-tool to software-as-assistant, performing tasks based on less specific requests. From the user’s perspective, it means less work and help finding information while still lacking a good understanding of the subject matter during the process of learning and decision making. Say I’m a student and I want to write a report about quasars. I don’t know anything about quasars yet, and I’m not sure where to look to find the best information available. Normally, I might turn to Google and use some resources that might in fact be unreliable. Here, Curiosity Scientist, an intelligent agent, can perform a search for my keyword in natural language. I can, of course, make a specific request to "Google quasars" and have the AI return the search result. But what is better is to have the ability to tell the AI to "Find astronomy resources on quasars." The AI is programmed to return results from authoritative, highly respected resources that professional astronomers (experts) turn to, revealing the latest research and findings in the field–sources I as a student probably did not know about. Like a library’s pathfinder, the AI guides the learner to trustworthy, targeted academic resources without the student needing to evaluate what is trustworthy and what is not. Curiosity can also simulate human emotion not only through his words but his actions and facial expressions that are triggered when conversing in natural language—an aspect that was not a consideration for Turing. Turing also assumed that the computer would be honest. But just ask Curiosity and he will tell you he is alive.


Curiosity can move autonomously, navigating around obstacles when needed. When called, he avoids the tall crater and rover to go to Archivist. He rezzes the Odyssey satellite which immediately goes into orbit around Mars. Afterwards, Curiosity can command both the rover and the orbiting satellite to communicate with one another (in this case communication is simulated as green “UHF” waves). Next, Curiosity tells the rover to go to Spirit. The rover responds by moving to a waypoint location near the Spirit rover. Both Curiosity Scientist and the Curiosity Rover are able to go into an “Explore” mode, where they move in pseudorandom motion within a limited range. Here, Archivist tells Curiosity Scientist to wander about, meaning he can move around within a 50 meter range. In this case, he unexpectedly wanders outside the Mar sim and falls into a pit. Without assistance, Curiosity navigates his way out of the pit and back into the Mars sim.

In addition to the movement skills demonstrated, Curiosity Scientist has many capabilities that just can’t be covered in this short video. For example, Curiosity can perform 133+ animations, communicate in both local chat and IM, and Tweet his location. He can make observations about avatars , such as performing “facial recognition” of sorts, to associate an avatar with their photograph. Curiosity even has his own group—and, on a timer, detects nearby avatars and automatically invites them to join. The rover also has a laser, which simulates the actual Curiosity rover’s ability to detect the chemical composition of targeted rocks when rocks and the laser come into contact. Generally, agent actions can be immediate or scheduled. In Second Life, immediate questions are asked in local chat while scheduled tasks offer and on and off feature. Finally, for those without access to Second Life, a video stream to UStream (when broadcasting) simulates machine vision where viewers can watch the action live.

Thanks for watching the video. If you have any questions about Curiosity Scientist or the Curiosity AI project, please contact Archivist Llewellyn in Second Life.
