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 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.
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.
"[5] 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.
[2] The case for a hastened timeline was bolstered, some observers believed, by the DoD's 2001 Quadrennial Defense Review, which warned of increasing threats to U.S. power projection.
In 2007, defense industry analyst Rebecca Grant called the bomber a "mythical beast" and lamented the Air Force's continued fixation on it.
