Gates Second Reader: ProfessorJames E. Suchan Approved for public release; distribution is unlimited ABSTRACT The Coast Guard Office of Aviation Plans and Programs continues to receive inquiries from several sources about the service's intentions concerning the V-22 tilt rotor aircraft. Officially, decision makers acknowledge that tilt rotor capabilities could be readily adaptable to the service's missions, but acquisition of the V-22 is not contemplated unless the aircraft is first fielded by a Department of Defense component. This thesis serves as a preliminary inquiry into tilt rotor applications for the Coast Guard. The purpose of the study is to determine the implications of a favorable V-22 production decision on the Coast Guard's current mix of aircraft. As background material, the thesis reviews the history of tilt rotor development and outlines the key economic issues at the center of the public policy debate likely to decide the V-22's future. Then, the V-22 Osprey is compared with each aircraft already in Coast Guard service. Both performance characteristics and costs are examined. Lastly, potential Coast Guard V-22 assimilation strategies are discussed. in ^u/U7in 77 TABLE OF CONTENTS I. INTRODUCTION 1 A. BACKGROUND 1 B. OBJECTIVES 4 C. SCOPE AND LIMITATIONS 4 D.
