U.S. Army reconnaissance and attack helicopter, currently being designed and tested and planned for deployment in the second half of the current decade.

If the USAF's F-117 and the Army's AH-64 spent a night of heated passion together, the product would be the RAH-66 (with, of course, some assistance from its true parents, designer/manufacturers Boeing and Sikorsky). Capable of low-observability (to radar, visual and audio detectors) flights into enemy territory for purposes of reconaissance, the Comanche can also perform pinpoint air-to-ground strikes using the same Hellfire missiles from the Apache and Longbow Apache.

The Comanche is intended to be assigned solo reconnaissance missions as well as being part of a flight of Apaches. Because it is approximately 0.15% to 75% as detectible as the AH-64A while being faster and more maneuverable, the Comanche can act as the eyes and ears for the main ground strike force that follows it. Tracking targets using a similar radar and computer system to the Apache's FCR (Fire Control Radar), the Comanche's onboard computer can recognize and track a number of targets (128 in current models) and communicate the locations and parameters of these targets to other aircraft (and ground units) on the 21st century battlefield.

But the Comanche isn't just a spotter. Armed in one of serveral configurations, the RAH-66 can carry tankbusting AGM-114 Hellfire missiles, air-to-air versions of FIM-92 Stinger missiles, or Hydra-70 2.75" rockets -- in addition to it's onboard and stealthily-packaged XM301 20mm three-barrel cannon. The missiles and rockets are stored in an internal weapons bay that swings open like the talons of a bird of prey -- at the expense of some stealth.

This powerful, versatile and downright sexy aircraft is controlled by two crewmembers: a pilot and weapons control officer. These two soldiers sit in a "glass cockpit" surrounded by re-assignable LCD displays and wear an advanced helmet that provides optically-tracked control of helicopter systems, most notably target selection. If you think that Canon Elan IIe camera where you can select a focusing point with your eye is cool, picture being able to glance at a black-market T-80 or BMP on the ground as it is destroyed moments later by your Hellfire missiles. Rowr.

Of course, all these fancy-schmancy computer systems need to be programmed. Between the dual mission computers, the survivability and flight control computers, the software-reprogrammable radios, the threat recognition and imaging control, and the redundant internal networking, the Comanche will have approximately 3.5 million lines of code. Compare to the AH-64 or OH-58, each with under 400 thousand; or at the other end of the spectrum, the new F-22 fighter, estimated at over 4 million.

Some numbers:

  • Powered by two 1440 hp turbine engines
  • Weighing in at about 2 tons when deployed with weapons
  • 5 rotor blades (supposedly because this configuration is quieter than 4; yay prime numbers)
  • 1,260 nautical mile range under normal mission characteristics
  • 160 knot cruise speed
  • 3 retractible landing wheels
  • 11 feet high, 46.78 feet long, 39.04 feet wide

By 2006, when fully fielded, the RAH-66 Comanche will replace both the OH-58D Kiowa Warrior and the remaining AH-1 Cobras and it will complement the AH-64 Apache. Full production is expected by 2010.

There may be a legion of reasons the Army would like to pull funding from the RAH-66 Comanche program, as was announced today. There may be a myriad of epic backroom politics, a plethora of front-chamber deals, and perhaps even a personal grudge or six involved. I don't know. I, personally, fixate on one aspect of the whole situation: the Silver Bullet Syndrome.

Put bluntly (and the Army has, publicly) we just don't need the Comanche at this time. I am personally somewhat surprised that an Armed Service has apparently decided to give up a 'sexy new' program in order to (they claim) handle the more mundane demands of force integration and readiness, but here we are. I will strike out on a limb and state that personally, I consider this but the first high-profile casualty of the current state of 'continuous sort-of war' that the United States seems to have slid into.

For those not in the know, the Comanche was to be the Army's next-generation 'armed reconnaissance' helicopter. It was to be stealthier than the Apache, faster than the current scout, the OH-54 Kiowa, and armed somewhere between the two. The concept was aired almost twenty years ago, when the demands on Army Aviation were fairly fixed - support the ground force maneuver war doctrine, against a notional large-scale armored and mechanized opponent in the European theater.

Under those conditions, an armed scout made sense. On a fluid mechanized battlefield, the most lethal threats a helo was likely to face were mounted air defense platforms such as the ZSU-23, and perhaps high-tech MANPADS in the hands of infantry - but only at close range. The role of the scout helicopter was to range ahead of the main force, locating targets, calling in fires, and - if necessary - providing emergency fast-moving firepower to augment lighter units. The Apache was the firepower, really; heavily armed, and armored, it was intended to go in harm's way by ambushing oncoming units. Using it to perform interdiction strikes and more offensive sweep operations, as the Army began to do in the Gulf War, was not originally on its agenda.

Fast forward to today. Iraq and Afghanistan have shown that the most severe threat to helicopters is not high-tech; it's low-tech. Massed small-arms fire, RPGs and man-portable automatic weapons are by far the most common threat to American helicopters operating in the field. While there are, indeed, MANPADS strikes on helos, they are (so far) exclusively IR guided, line-of-sight shots - against which the vaunted stealth of the Comanche offers no protection. Furthermore, in such operating conditions, two things offer better chances of survival - armor and redundancy, as the Apache has, or massive suppressing fire, which the Apache also has. A large degree of survivability could be added to the existing utility helo fleet through the installation of flare and chaff dispensers, perhaps; but this costs money.

The Army notes another problem. There is no standard aviation unit at present. There is a wild mix of airframes and numbers across the various aviation brigades in the force; Reserve units are still using 1970s AH-1s and UH-1s instead of Apaches and Blackhawks. This means that there is almost no commonality in the logistics tail between a frontline unit and its reserve aviation component.

Basically, the Army is proposing to take the huge chunks of money already allocated to Comanche - $17 billion at minimum, through 2010 - and to refit the existing units with aircraft identical to the present frontline units, as well as to upgrade the existing aircraft with survivability and lethality improvements, and to fund the readiness of the aviation component. This is a fairly radical proposal for American defense procurement. Note that they're not talking about giving the money back, just spending it elsewhere. The base effect would be to ensure that when units are deployed, they would deploy with a common set of aircraft; to ensure that there are additional heavy attack helos (Apaches) to meet demand, and to fund long-lead and marginal spares and training to keep availability up.

This doesn't leave us entirely without scouts; the OH-58D Kiowa Warriors are not all that old, and will be around for some time. Plus, the Apache Longbow upgrades include the addition of a mast-mounted sensor array (MMS) similar to what the Warriors carry; these units will be able to perform the original mission - long-range scouting in a maneuver battle - and purchasing additional units means that they can do so without detracting from the available combat power of the main force.

There are, of course, questions that must be asked. To wit: Why was this decision made now, after the Comanche plant had been built? Is this related to the constant stresses of post-9/11 OPTEMPO and the consequent demands on the aviation forces? Are we really sure that we want to give up the high-tech anti-armor (and, lest it be forgot, stealthy Special Ops strike support) capabilities that the Comanche would have offered? If, in fact, this is due to the increased demands on the aviation forces that the present one-point-five wars are making, why is this shortfall being met by reallocating Army capital budgets rather than by additional outlays for readiness and operations? Coupled with the four service Chiefs' testimony before Congress that none of their services had received any information about special drafts to fund the coming year's operations, this is a pertinent issue. There are rumblings that the Bush administration is planning on delaying any such funding requirements until after the election, which, while legal, borders on the pusillanimous, especially if it leaves our forces in any way compromised. Given the present state of affairs, I do not trust the Bush administration (or, for that matter, the Chiefs of service, albeit for different and more understandable reasons) to tell me, as an American citizen, when my armed forces are being hamstrung for political expediency.
