Support RAND Make a tax-deductible charitable contribution at www.rand.org/giving/contribute www.rand.org Preface Remotely piloted aircraft (RPA) and the personnel that operate them are well understood to be crucial to mission success in today’s Air Force, and demand for skilled pilots continues to grow rapidly. However, recent studies have suggested that personnel in the RPA pilot career field are dissatisfied with aspects of the job and are experiencing stress as a result. Although those studies suggest that a variety of workplace factors are leading to the stress and dissatisfaction, a large portion of them relate to issues associated with career field planning. These career field planning issues exist, in part, because of the newness and rapid growth of the RPA enterprise. The 18X RPA pilot force (those whose first and only rated job is as an RPA pilot) is only six years old, and plans for the future of the career field are still evolving. Moreover, as the rapid growth in demand for 18X pilots has outpaced the Air Force’s ability to produce them, the Air Force is now struggling to train and retain enough personnel to meet the demand. As a result, Air Force leadership has recognized that a more thoughtful and stable plan for how to manage the career field is needed to ensure the health of the force in the future. The Director of Training and Readiness (AF/A3T) therefore asked RAND Project AIR FORCE to assist in building a long-term field planning model that addresses those force health issues and the timeline required to build a healthy and sustainable career field. This report documents RAND’s efforts to develop that long-term career field planning model; explains its main features, underlying content, and data inputs; and describes key technical aspects of the model. More specifically, this study (1) used input from Air Force leadership, stakeholders, and subject-matter experts to define what a healthy and sustainable RPA pilot career field shape across commissioned years of service (CYOS) might look like in the long term in terms of desired end-state requirements that incorporate aspects meant to improve satisfaction within the career field, and (2) built a linear programming model that specifies the number and type of RPA pilots that should be produced annually from the training pipeline to achieve that end-state career field shape across CYOS. Using this linear programming model, the RAND team then explored the implications of a few pilot production and retention scenarios for the long-term health of the career field when compared with this set of desired end-state requirements. This report is intended to provide information about the development of the model. It should also be of interest to those concerned with the technical modeling aspects of career field health planning. This research was commissioned by the U.S. Air Force and conducted within the Manpower, Personnel, and Training Program of RAND Project AIR FORCE as part of a fiscal year 2016 project, Building a Healthy and Sustainable RPA Career Field Using 18X, ALFA Tour, and 11U/12U Pilots. iii RAND Project AIR FORCE RAND Project AIR FORCE (PAF), a division of the RAND Corporation, is the U.S. Air Force’s federally funded research and development center for studies and analyses. PAF provides the Air Force with independent analyses of policy alternatives affecting the development, employment, combat readiness, and support of current and future air, space, and cyber forces. Research is conducted in four programs: Force Modernization and Employment; Manpower, Personnel, and Training; Resource Management; and Strategy and Doctrine. The research reported here was prepared under contract FA7014-16-D-1000. Additional information about PAF is available on our website: http://www.rand.org/paf/ This report documents work originally shared with the U.S. Air Force on June 7, 2016. The draft report, issued in September 2016, was reviewed by formal peer reviewers and U.S. Air Force subject-matter experts. iv Contents Preface ............................................................................................................................................ iii Figures............................................................................................................................................ vi Tables ........................................................................................................................................... viii Summary ........................................................................................................................................ ix Acknowledgments ....................................................................................................................... xvii Abbreviations ............................................................................................................................. xviii 1.

  • 1 17A Stealth Fighter Organizations
    HISTORY AND LINEAGE OF THE F- 1 17A STEALTH FIGHTER ORGANIZATIONS DECEMBER 1991 SPECIAL STUDY HO-91-2 OFFICE OF HIST RY HEADQUARTERS, 37TH FPGHTER WING TWELFTH AIR FORCE TACTICAL AIR COMMAND INTRODUCTION In 1978, the Air Force awarded a full-scale development contract for the F-117A Stealth Fighter to Lockheed Corporation's Advanced Development Projects (the famous Skunk Works). Thirty- one months later, on 18 June 1981, the F-117A made its first flight. Meanwhile, the Tactical Air Command (TAC) decided to set up a group-level organization to guide the F-117A to an initial operating capability. That organization became the 4450th Tactical Group (TG), which officially activated on 15 October 1979 at Nellis AFB, Nevada. The 4450 TG began flying operations in 1981 from the Tonopah Test Range Airfield, located approximately 130 miles northwest of Las Vegas, Nevada. Lockheed test pilots put the Stealth Fighter through its early paces. The 4450 TG also operated the A-7D as a surrogate trainer for the F-l17A, and these operations continued until 15 October 1982 under the guise of an avionics test mis- sion. October 15th is important to the program because on that date Maj Alton C. Whitley, Jr. became the first 4450 TG pilot to fly the F-117A. The 4450 TG then achieved an initial operating capability with the F-117A in October 1983. The 4450 TG's mission continued to evolve under a cloak of secrecy--all Tonopah training flights conducted at night under the cover of darkness--until late 1988. On 10 November 1988, the Air Force brought the F-117A from behind a "black veil" by publicly acknowledging its existence.

  • WRP New Mexico Military Asset List (MAL)
    WRP New Mexico Military Asset List (MAL) Within the Western Regional Partnership (WRP) region, there are significant military testing and training installations and ranges. WRP developed summaries from all of the Services and the National Guard, describing the history, missions, and importance of these assets. These summaries use only publicly available information and are written for the policy maker new to military issues and the military savvy person needing specific military information. It is our hope that WRP Partners use these summaries as a tool for land use planning efforts to encourage compatible growth and ensure future mission viability. Incompatible development (encroachment) comes in many forms but for the military, it means those issues that affect their ability to fulfill their mission on land, in the sea, or in the air. These military summaries are for general planning purposes. Attached New Mexico MAL summaries: Air Force: • Cannon Air Force Base • Holloman Air Force Base • Kirtland Air Force Base • Melrose Air Force Range Army: • Fort Bliss • Fort Bliss Training Center • White Sands Missile Range National Guard: • New Mexico Air National Guard • New Mexico Army National Guard Military Asset List 2016 U.S. Air Force CANNON AIR FORCE BASE : NEW MEXICO Cannon Air Force Base (AFB) is located on the high plains of Eastern New Mexico, near the Texas panhandle. It is named in honor of the late Gen. John K. Cannon, former commander of the Tactical Air Command.

  • Tuskegee Airmen Chronology
    TUSKEGEE AIRMEN CHRONOLOGY DANIEL L. HAULMAN ORGANIZATIONAL HISTORY BRANCH AIR FORCE HISTORICAL RESEARCH AGENCY MAXWELL AFB, AL 36112-6424 24 November 2015 1 A TUSKEGEE AIRMEN CHRONOLOGY INTRODUCTION For decades after World War II, the first black pilots in American military history were relatively unknown. Americans became increasingly aware of the contributions of African Americans to their cultural heritage during and after the Civil Rights Movement in the 1950s and 1960s. By the end of the twentieth century, the “Tuskegee Airmen” had become famous in newspaper and magazine articles, books, films, television programs, and museum exhibits. Unfortunately, their story was told not only by historians using primary source documents, but also by others less familiar with history than with legend. A number of false claims circulated, many of them based on an ignorance of the chronological sequence of events that formed the skeleton of the true story. This book is an effort to provide a framework for Tuskegee Airmen history while at the same time revealing their historically significant accomplishments. Having worked at the Air Force Historical Research Agency for more than thirty-two years, I have developed an appreciation for the invaluable collection of documents on Army Air Forces organizations in World War II that is maintained there. Many of the documents describe the most famous Tuskegee Airmen organizations such as the 99th, 100th, 301st, and 302nd Fighter Squadrons that were assigned to the 332nd Fighter Group during World War II, which escorted American B-17 and B-24 bombers over Nazi targets in central Europe, its pilots flying red-tailed P-51 Mustangs.
