Utility Helicopters

• Our analysis indicates that among utility platforms, the Boeing CH-47D, Sikorksy S-61T, Eurocopter AS-332L1 Super Puma, and the AgustaWestland AW139 are consistently more cost-effective than the reference helicopter, the Mi-17v5. The Sikorsky S-61T+ performs similarly well, but is in development.
• In these cases, the margin of increase in cost-effectiveness over the Mi-17v5 often is such that these aircraft achieve greater efficiency even when additional tail requirements are applied.
• Several small utility helicopters also had good cost-effectiveness, including the Eurocopter EC-145 (LUH-72A Lakota) and the AgustaWestland AW109.

Attack Helicopters

• For attack aircraft, the AH-1Z and the AW129 are able to accomplish many of the same routes as the Mi-17v5. That makes these aircraft feasible candidates for providing armed escort, and for overwatch of mobility helicopters.
