A Clipped Wing: An Assessment of the Effectiveness of the B-21 _________________________ A Thesis Presented to the Faculty of the Josef Korbel School of International Studies University of Denver _________________________ In Partial Fulfilment of the Requirements for the Degree Master of Arts _________________________ by Aidan Thomas Hughes June 2016 Advisor: Professor T. Farer Author: Aidan Thomas Hughes Title: A Clipped Wing: An Assessment of the Effectiveness of the B-21 Advisor: Professor T. Farer Degree Date: June 2016 Abstract This thesis examines the effectiveness of the Northrop Grumman B-21 long range strike bomber in advancing the ability of U.S. policy makers to achieve national security objectives. The operational value of the B-21 is assessed through analysing its probable role in four hypothetical combat scenarios, and the relative effectiveness of the B-21 is measured alongside the potential performance of alternative systems. This operational analysis is augmented by a consideration of the shape of recent U.S. national security strategies, as well as the anticipated future security environment, which provides the foundation of an analysis of the ability of the B-21 to support U.S. security objectives within the context of U.S. policy makers' intended approach to foreign policy. This thesis concludes that the B-21 provides a limited increase in the effectiveness of U.S. military operations, and its procurement is incompatible with the anticipated future shape of U.S. security strategy and global interaction. ii Table of Contents Glossary of Abbreviations ................................................................................................. iii Chapter One: Introduction .................................................................................................. 1 Thesis Structure ............................................................................................................... 3 Definitions ....................................................................................................................... 5 The History of Airborne Long Range Strike ................................................................... 7 Operational U.S. Long Range Strike Bombers ............................................................. 16 Boeing B-52 'Stratofortress' ....................................................................................... 17 Rockwell B-1B 'Lancer' ............................................................................................. 18 Northrop Grumman B-2 'Spirit' ................................................................................. 20 Likely Performance Attributes of the B-21 ................................................................... 21 Chapter Two: The Evolution of U.S. Global Outlook and Foreign Policy ....................... 25 Chapter Three: Global Threats to U.S. Security ............................................................... 35 East Asia and the Pacific ............................................................................................... 37 The Middle East ............................................................................................................ 44 The Russian Sphere of Influence ................................................................................... 49 Chapter Four: Scenario Analyses ...................................................................................... 52 Hypothetical Scenario One: Countering Chinese Aggression in East Asia .................. 53 Strategic considerations for U.S. military action .......................................................... 54 Role of the B-21 ............................................................................................................ 57 Hypothetical Scenario Two: Defeating ISIL in the Middle East .................................. 66 Strategic considerations for U.S. military action .......................................................... 67 Role of the B-21 ............................................................................................................ 76 Hypothetical Scenario Three: Countering a Nuclear Iran ............................................. 85 Strategic considerations for U.S. military action .......................................................... 86 Role of the B-21 ............................................................................................................ 92 Hypothetical Scenario Four: Countering Assertive Russian Action in the Arctic ...... 106 Strategic considerations for U.S. military action ........................................................ 107 Role of the B-21 .......................................................................................................... 111 Chapter Five: Cost Considerations and Psychological Impact ....................................... 120 Chapter Six: Alternative Future Long Range Strike Systems ........................................ 128 Prompt Global Strike ................................................................................................... 128 High-Altitude Long Endurance Remotely Piloted Aircraft ........................................ 131 Chapter Seven: Conclusion ............................................................................................. 135 Bibliography .................................................................................................................... 151 iii Glossary of Abbreviations A2AD Anti-Access Area Denial CEP Circular Error Probable CAS Close Air Support DoD Department of Defense (U.S.) HALE High-Altitude Long Endurance IADS Integrated Air Defence System ISIL Islamic State of Iraq and the Levant ISR Intelligence, Surveillance, and Reconnaissance JASSM Joint Air-to-Surface Stand-Off Missile JDAM Joint Direct Attack Munition LRSB Long Range Strike Bomber LRSO Long Range Stand-Off MANPADS Man-Portable Air Defence System NATO North Atlantic Treaty Organisation RPA Remotely Piloted Aircraft UN United Nations iv Chapter One: Introduction "Hitler built walls round his 'Fortress Europe' but he forgot to put a roof on it." F.D. Roosevelt, 19431 On the 27th of October 2015, the U.S. Department of Defense (DoD) announced the award of a $55bn contract to Northrop Grumman for the production of a new Long Range Strike Bomber (LRSB), designated the "B-21".2 This contract marked the end of a research and design phase that had lasted for almost a decade, and started the wheels turning on the production of the first new U.S. long range strike aircraft since the twenty- first, and final, B-2 'Spirit' rolled off Northrop Grumman's production line and entered service in 1997.3 Never before has the U.S. spent so long without a LRSB either in production or being designed under contract.4 1 Donald L.

The equivalent, perhaps, of re-soling a pair of patent leather brogues that are wearing through after many years of use. However, taking this analogy further, re-soling the old pair of shoes does not necessarily make them appropriate for future use. No matter the skill of the cobbler, it is unlikely that the brogues will be suitable footwear if the wearer is attempting to play tennis. The decision to procure a new LRSB, 're-soling' the existing U.S. LRSB fleet, should not, therefore, be a foregone conclusion, regardless of any perceived shortfall in the current or anticipated future performance of existing U.S. LRSBs. Such an order should not simply represent the purchase of a new system for the U.S. military to deploy in combat, but rather be a statement of purpose, an effective tool that, within the context of U.S. grand strategy, increases the effectiveness of the military
