Watts Thinking Center for Strategic Smarter and Budgetary Assessments About Defense www.csbaonline.org Six Decades of Guided Munitions and Battle Networks: Progress and Prospects by Barry D. Watts Center for Strategic and Budgetary Assessments March 2007 ABOUT THE CENTER FOR STRATEGIC AND BUDGETARY ASSESSMENTS The Center for Strategic and Budgetary Assessments (CSBA) is an independent, nonprofit, public policy research institute established to make clear the inextricable link between near-term and long- range military planning and defense investment strategies. CSBA is directed by Dr. Andrew F. Krepinevich and funded by foundations, corporations, government, and individual grants and contributions. This report is one in a series of CSBA analyses on the emerging military revolution. Previous reports in this series include The Military-Technical Revolution: A Preliminary Assessment (2002), Meeting the Anti-Access and Area-Denial Challenge (2003), and The Revolution in War (2004). The first of these, on the military-technical revolution, reproduces the 1992 Pentagon assessment that precipitated the 1990s debate in the United States and abroad over revolutions in military affairs. Many friends and professional colleagues, both within CSBA and outside the Center, have contributed to this report. Those who made the most substantial improvements to the final manuscript are acknowledged below. However, the analysis and findings are solely the responsibility of the author and CSBA. 1667 K Street, NW, Suite 900 Washington, DC 20036 (202) 331-7990 CONTENTS ACKNOWLEGEMENTS .................................................. v SUMMARY ............................................................... ix GLOSSARY ………………………………………………………xix I.

    Contents Puge FOREWORD ...................... u 1947-56 ......................... 1 1957-66 ........................ 19 1967-76 ........................ 45 1977-86 ........................ 81 1987-97 ........................ 117 iii Foreword This chronology commemorates the golden anniversary of the establishment of the United States Air Force (USAF) as an independent service. Dedicated to the men and women of the USAF past, present, and future, it records significant events and achievements from 18 September 1947 through 9 April 1997. Since its establishment, the USAF has played a significant role in the events that have shaped modem history. Initially, the reassuring drone of USAF transports announced the aerial lifeline that broke the Berlin blockade, the Cold War’s first test of wills. In the tense decades that followed, the USAF deployed a strategic force of nuclear- capable intercontinental bombers and missiles that deterred open armed conflict between the United States and the Soviet Union. During the Cold War’s deadly flash points, USAF jets roared through the skies of Korea and Southeast Asia, wresting air superiority from their communist opponents and bringing air power to the support of friendly ground forces. In the great global competition for the hearts and minds of the Third World, hundreds of USAF humanitarian missions relieved victims of war, famine, and natural disaster. The Air Force performed similar disaster relief services on the home front. Over Grenada, Panama, and Libya, the USAF participated in key contingency actions that presaged post-Cold War operations. In the aftermath of the Cold War the USAF became deeply involved in constructing a new world order. As the Soviet Union disintegrated, USAF flights succored the populations of the newly independent states.

  • Expanding the Envelope--Stealth and Other Strike Roles
    Expanding the Envelope— Stealth and Other Strike Roles Carlo Kopp The advent of combat aircraft possessing Low Observable (LO) characteristics has revolutionised many well established roles, yielding an unprecedented reduction in combat loss rates. Low Observables have returned, for the first time since the introduction of radar, the advantage of surprise to the attacking bomber. The Lockheed F-117A, Northrop B-2, Lockheed-Martin/Boeing F-22 and planned multi-service JSF are all intended to exploit their LO characteristics in penetrating defended airspace to strike surface targets. Hitherto the focus in developing strike capabilities in these types has been upon the strategic strike, lethal defence suppression and fixed battlefield target interdiction roles. The target set for these roles encompasses primarily non-moving, high value, land based assets. The primary guided weapon used by the F-117A is the laser guided bomb, and both the Raytheon built GBU-27 and older GBU-10 weapons have been used operationally. Both weapons provide precision and the choice of the unitary Mk.84 warhead or the concrete piercing BLU-109/B. The limitation of both weapons is the need for a clear line of sight to the aimpoint to ensure that the laser reflections off the target can be seen by the bomb seeker. Ongoing development of GBU-24/27 includes incorporation of a GPS receiver to improve weapon flightpath management, and provide a backup guidance mode if the laser paint is lost. The primary guided weapon for the B-2A is the Boeing GBU-31 Joint Direct Attack Munition (JDAM), which employs a guidance package built around the HG1700 ring laser gyro and the GEM-III GPS receiver.1 It supplants the earlier Northrop GBU-36 GAM weapon, which pioneered the GPS/inertial bomb guidance principle.2 The tailkit can be fitted to the Mk.84 or the BLU-109/B warheads.

Roche’s charge to reinvigorate the systems engineering profession, the Air Force Institute of Technology (AFIT) undertook a broad spectrum of initiatives that included creating new and innovative instructional material. The Institute envisioned case studies on past programs as one of these new tools for teaching the principles of systems engineering. Four case studies, the first set in a planned series, were developed with the oversight of the Subcommittee on Systems Engineering to the Air University Board of Visitors. The Subcommittee includes the following distinguished individuals: Chairman Dr. Alex Levis, AF/ST Members Brigadier General Tom Sheridan, AFSPC/DR Dr. Daniel Stewart, AFMC/CD Dr. George Friedman, University of Southern California Dr. Andrew Sage, George Mason University Dr. Elliot Axelband, University of Southern California Dr. Dennis Buede, Innovative Decisions Inc. Dr. Dave Evans, Aerospace Institute Dr. Levis and the Subcommittee on Systems Engineering crafted the idea of publishing these case studies, reviewed several proposals, selected four systems as the initial cases for study, and continued to provide guidance throughout their development.

  • NSIAD-97-134 Operation Desert Storm: Evaluation of the Air Campaign
    United States General Accounting Office Report to the Ranking Minority Member, GAO Committee on Commerce, House of Representatives June 1997 OPERATION DESERT STORM Evaluation of the Air Campaign GAO/NSIAD-97-134 United States General Accounting Office GAO Washington, D.C. 20548 National Security and International Affairs Division B-276599 June 12, 1997 The Honorable John D. Dingell Ranking Minority Member Committee on Commerce House of Representatives Dear Mr. Dingell: This report is the unclassified version of a classified report that we issued in July 1996 on the Operation Desert Storm air campaign.1 At your request, the Department of Defense (DOD) reevaluated the security classification of the original report, and as a result, about 85 percent of the material originally determined to be classified has subsequently been determined to be unclassified and is presented in this report. The data and findings in this report address (1) the use and performance of aircraft, munitions, and missiles employed during the air campaign; (2) the validity of DOD and manufacturer claims about weapon systems’ performance, particularly those systems utilizing advanced technology; (3) the relationship between cost and performance of weapon systems; and (4) the extent that Desert Storm air campaign objectives were met. The long-standing DOD and manufacturer claims about weapon performance can now be contrasted with some of our findings. For example, (1) the F-117 bomb hit rate ranged between 41 and 60 percent—which is considered to be highly effective, but is still less than the 80-percent hit rate reported after the war by DOD, the Air Force, and the primary contractor (see pp.
