Abstract : Rotary winged aviation has served the Department of Defense (DoD) and, more specifically, the U.S. Army for decades by providing airlift, service support, and attack capabilities for varying missions and combat-unique situations. To date, the payload and capabilities of helicopter platforms have been continually manipulated to obtain optimal performance and cost-effectiveness. DoD and Defense Contractors are now seeking the next level of rotorcraft development -- an increase in helicopter airspeed. An increase in airspeed is now considered one of the most important next-generation rotorcraft improvements. The challenge is to build a helicopter that can hover under load, move the required payload, and fly faster than current helicopter platforms. These improvements will allow greater service ranges, provide faster response times, and provide needed cost reductions. This paper will address the history and evolution of high-speed rotorcraft capabilities, typical roles and missions, and the advantages and disadvantages of the U.S. Army developing and procuring high-speed helicopters. Specifically, the paper will attempt to answer the following questions: (1) Are these types of aircraft practical for use in the Army inventory?, (2) What is the timeline associated with development?, and (3) Will the DoD be able to afford this capability?
