Joint Replacement Aircraft: The Case for a Single Multi-Mission HMLA Platform
Abstract
The proposed introduction of the Joint Replacement Aircraft, as a follow-on for the UH-1Y/AH-1Z program, is an ideal opportunity to build a single platform that performs both the rotary-wing attack and utility missions for the Marine Corps. Historically, the Marine Light/Attack Helicopter missions have been flown by two different aircraft. The AH-1 Cobra performs the attack mission, while the UH-1 Huey handles various "utility" tasks. Originally assigned in equal numbers, each squadron is now equipped with 18 AH-1W Cobras and 9 UH-1N Hueys. The two-to-one ratio is indicative of a trend. Over the years, the UH-1N's performance has been eroded by the increased weight of new systems. This reduced capability has left many questioning the worth of a "utility" platform. The poor capability of the UH-1N is mistakenly viewed as a reflection on the poor value of multi-purpose helicopters in general. Although the Huey and Cobra are both Bell products that originally shared many components, the Cobra has received extensive upgrades since its introduction. As a result, the two helicopters now share very few parts and require specialized maintenance training. In an effort to correct these deficiencies, the four bladed UH-1Y/AH-1Z program was initiated to improve performance and dramatically increase commonality. When these new helicopters begin arriving in 2003, they will share 85% in common components. While the UH-1Y/AH-lZ program an important step in the right direction, an opportunity for even greater benefits lies ahead. An undeveloped concept program, the Joint Replacement Aircraft, is slated for introduction in the 2015 to 2020 time frame. Although the design is still open, many involved with the acquisition process believe that a tilt-rotor or futuristic canard rotary wing concept is favored over a conventional helicopter.
