The United States Air Force Statistical Digest has been published each year since 1948. While the Digest has had several changes in format over the years, the original purpose for publishing it has not changed. The purpose has been, and will continue to be, to compile each fiscal year a single authoritative archival document providing a statistical description of the Air Force in terms of resources, organizations, and major activities. Individuals requiring a historical description in statistical terms of each fiscal year of the Air Force's existence have found theDigest to be an invaluable addition to their information reference sources.This Fiscal Year 1993 Statistical Digest continues a format containing only actuals. Projections for the future included in previous Statistical Digests were eliminated with the publication of the FY91 Statistical Digest. Tabular and graphic presentations of data have been reformatted.The United States Air Force Statistical Digest entitled "Fiscal Year 1992/1993 Estimate" published and distributed by this office in late 1992 should no longer be used as a source of any data for FY 1991, FY 1992, and FY 1993. Much of the data in this late December 1992 edition of the Statistical Digest were estimates. The latest and authoritative edition of the Statistical Digest is this edition entitled "Fiscal Year 1993" which contains only actual data.
