In 1998, a Congressional panel studied the merits of re-starting
B-2 Spirit production, which had ended prematurely at 21 aircraft, far short of the originally planned 132 stealth bombers. The panel nonetheless endorsed ending production in favor of re-allocating resources towards B-2 upgrades or developing technology for a future new-build aircraft. A few weeks later Congress ordered the Department of the Air Force to update its bomber roadmap, last reviewed in 1992. The resulting Long Range Bombers white paper released in March 1999 projected that a new "capability" would be needed to be fielded in the 2037 time frame. The paper estimated that due to mishap attrition and other factors other than useful service life, the number of
B-1 Lancer would not meet Air Force requirements of 89 aircraft by 2018. For the B-2, the number of aircraft would slip below the service's requirements of 19 aircraft by 2027 due to a combination of mishaps and retirements due to end of service life. It predicted it would need to begin retiring B-1s at the end of their service life around 2038. For the
B-52 Stratofortresses, the report estimated the service would be "unable to maintain our requirement of 62 aircraft by 2044." The Air Force's near-term strategic bombing needs could be met through service extensions and technology enhancements offering "a tenfold increase in bomber lethality" compared to 1992, according to the paper. The Department of the Air Force's contentment with the size and age of the bomber fleet disappointed some members of Congress who believed a new aircraft would be needed before 2037. The report said developments in adversary air defenses would threaten U.S. air power in future conflicts, and that access to enemy
denied areas would be limited to stealth aircraft. The Air Force conceded that a new bomber would be needed earlier when it updated its service life projections in November 2001. The paper's recommendations were adopted as Air Force policy by
