DOD has set key decision points for deciding whether to further invest in capabilities to destroy missiles during the initial phases after launch. In March 2006, DOD issued a report on these capabilities in response to two mandates. To satisfy a direction from the House Appropriations Committee, GAO agreed to review the report. To assist Congress in evaluating DOD's report and preparing for future decisions, GAO studied the extent to which DOD (1) analyzed technical and operational issues and (2) presented complete cost information. To do so, GAO assessed the report's methodology, explanation of assumptions and their effects on results, and whether DOD followed key principles for developing life-cycle costs. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-07-430/html/GAOREPORTS-GAO-07-430.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-07-430/pdf/GAOREPORTS-GAO-07-430.pdf GAO-07-430 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-07-430 Other Written Product GAO-07-430; Missile Defense: Actions Needed to Improve Information for Supporting Future Key Decisions for Boost and Ascent Phase Elements; Ballistic missiles Cost analysis Defense budgets Defense capabilities Defense cost control Defense procurement Future budget projections Life cycle costs Standards Systems development life cycle MDA Airborne Laser Program MDA Kinetic Energy Interceptor System MDA Terminal High Altitude Area Defense System H.
