In its consideration of the fiscal year 1990 defense budget, the House Armed Services Committee trimmed $800 million from the B-2 research and development budget, while at the same time staving off a motion to end the project. Opposition in committee and in Congress was mostly broad and bipartisan, with Congressmen Ron Dellums (D-CA), John Kasich (R-OH), and John G. Rowland (R-CT) authorizing the motion to end the project, others in the Senate, such as Jim Exon (D-NE) and John McCain (R-AZ), also opposing the project.[35]

The escalating cost of the B-2 program and evidence of flaws in the aircraft's ability to elude detection by radar,[35] were among factors that drove opposition to continue the program. At the peak production period specified in 1989, the schedule called for spending US$7 billion to $8 billion per year in 1989 dollars, something Committee Chair Les Aspin (D-WI) said "won't fly financially."[36] In 1990, the Department of Defense accused Northrop of using faulty components in the flight control system; the threat posed by bird ingestion potentially damaging engine fan blades also required redesigning.[37]


...the more sophisticated you make things, more things can go wrong...!

...with a low or lower or very low horizontal radar imprint image, it sure has a viewable vertical size and satellite detection...!

...very easy to counter with anti-aircraft canons...!

...the service ceiling is not anything extraordinary! the Russians "landed" a U2 flying much higher than 50,000 feet...!
