The Congress of the United States has directed the U.S. Coast Guard to determine the potential offered by tiltrotor aircraft technology, more specifically the V-22, for three Coast Guard functions; Search and Rescue (SAR), Law Enforcement/Maritime Interdiction (LE/MI), and Marine Environmental Protection (MEP). This study examines potential employment scenarios of the V-22 in the identified mission components, measures the operational effectiveness of the V-22, and determines the manpower and operating costs associated with those employments. The effectiveness and costs of the V-22 are compared with the effectiveness and costs of the four aircraft models which the USCG expects to employ in 1998. These four aircraft are the HH-6OJ, the HH-65A, the HC-13OH, and the HU-25A/B/C and represent the baseline aircraft alternatives for this analysis. In general, the V-22 offers some distinct advantages over the baseline helicopter fleet due to its ability to cruise at fixed-wing airspeeds, to operate at greater distances and to transport more cargo/personnel than either the HH-65 or the HH-60. In addition, the fixed-wing capabilities of the V-22 are, for the most part, equal to or slightly better than the HU-25. The greater speed of the HU-25 is generally offset by the greater operational radius and the mission flexibility provided by the dual role (helicopter and fixed-wing) capacity of the V-22. These advantages become marginal, however, when examined in the context of the historical USCG employment of aircraft in SAR, LE/MI, and MEP. The study also indicates that tiltrotor technology would substantially increase USCG operating costs over current aircraft while having a negligible effect on manpower costs of the baseline fleet.
