But the deeper reason is structural. The B-1B&#8217;s airframes wore out faster despite being decades newer: 20 years of hard, low-level flying caused severe structural strain, with some airframes needing $10-30 million each just to remain flightworthy.<\/p>\n<p>The B-52 was <strong>overbuilt<\/strong> for its mission. Its airframes have accumulated far fewer flight hours relative to their structural life. It is vastly cheaper to operate than either the B-1 or B-2.
