The U.S. Army is set to field the fastest, most maneuverable AH-64D Apache Longbows in its history, but it might be the sensors inside the attack helicopter's black boxes that end up defining it.
Pilots will have a window into each perspective on the battlefield - from the soldiers on the ground, the unmanned aerial systems (UAS) flying nearby, or a Kiowa scout helicopter already on station. It is part of the larger Manned Unmanned Teaming Level 2 project the Army is pursuing to integrate the influx of sensors populating Army aircraft underbellies.
Block III Apaches feature performance upgrades to help the aircraft fly and hover in mountainous terrains found in Afghanistan, and improve maneuverability bled off the aircraft by adding weight to the D-model Longbows.
Engineers added a 701D engine, composite rotor blades and an Improved Drive System of the 21st Century Face Gear Transmission, which provides the aircraft more power. These upgrades will give pilots 6K/95 hover performance: the helicopter can hover at 6,000 feet even when the temperature hits 95 degrees Fahrenheit.
What some in the aviation community find more exciting are the upgraded antennas and computing power added to the Block III. Feeds from UAS and nearby helicopters will be fed into the Apache's digital cockpit. Apache pilots can also record feeds and send them to other Apache, Kiowa and UAS pilots as well as troops with the One System Remote Video Terminal.
The first Block III Apache will roll off Boeing's production line in October, said Col. Shane Openshaw, the Apache program's project manager. Five combat aviation brigades - the 1st, 10th, 101st, 3rd and 229th - will fly Block IIIs by 2013.
The first Block III Apaches will be sent to the 101st Combat Aviation Brigade. The addition of the Block III will allow the service to retire the A model by 2013.
The 101st will become the first full-spectrum combat aviation brigade in the Army, adding a Grey Eagle UAS company and two Shadow platoons. Incorporating the Block III Apaches will help fast-track that process, Openshaw said.
"The 101st will effectively be writing all the tactics, techniques and procedures to be utilized through the system. We've learned a lot through VUIT-2, but this has even more capability," said Lt. Col. John Vannoy, product manager for Apache Sensor Systems.
VUIT stands for video from unmanned aircraft systems for interoperability teaming.
Aviation leaders want soldiers on the ground to walk Apache pilots onto targets, as both look at the same video that is broadcast from an RQ-7B Shadow UAV. And if the Apache is called to a different target, the pilots can send that same video to another Apache or Kiowa, replacing them in the fight.
Security of that data has been an additional concern the past couple years. Block III Apaches will have Tx/Rx encryption that will allow them to protect the signals being sent via the Ku-band digital antennas. Encrypting the data has added to the challenge of making sure everyone is on the same page, said Col. Gregory Gonzalez, head of the Army's UAS Project Office.
"Encryption of all these data links just changes things to an enormous degree, because then you have to make sure all the data links work but make sure you have the right crypto for it," Gonzalez said.
The Apache's new Ku-band antennas have a longer range - 15 versus 12 kilometers - than the VUIT that preceded the newer Apaches. The system also takes half the time to boot up. It took up to five minutes; now pilots can start it in less than three.
Block III Apache's additional computing also comes with a bonus: Its total system weight is 49 pounds lighter than VUIT.
The Army will test the Block III Apaches and how effectively the service has advanced in integrating UAS with manned aircraft this September at Dugway Proving Ground, Utah. Shadows, Grey Eagles, Kiowas and Apaches will fly in the Manned/Unmanned Systems Integration Capability exercise running through different battlefield scenarios with troops on the ground.
"This gives us a chance to show the maturation of the TTPs [tactics, training and procedures] we've developed over the past few years and test out a few new ones to make this work even better," said Tim Owings, Army UAS deputy program manager.
Getting helicopter pilots on board for the manned-unmanned teaming concept and an exercise like this has allowed the Army to turn the corner towards integrating each aviation asset more seamlessly on the battlefield, Gonzalez said.
"The manned aviation community started off not caring about unmanned systems, then they were pretty agnostic about it, now they are not only hopeful but they want what we can provide them," Gonzalez said.
