The Air Force evaluated the designs, and in September deemed them too large and complicated for operations.

This helped trap the shock wave under the wing between the downturned wing tips. The interceptor could descend to lower altitudes to increase the amount of visible sky, but doing so would limit its radar range in the same way as the missile sites, as well as greatly increasing fuel use and thus reducing mission xn-70.

North American scoured available literature to find any additional advantage. Central Intelligence Agency, As such, two prototype aircraft, designated XBAwere built; these aircraft were used for supersonic test-flights during — The Air Force changed the program to full weapon development and awarded a contract for an XB prototype and 11 YBs in August The introduction of the first Soviet surface-to-air missiles in the late s put the near-invulnerability of the B in doubt.

The US was aware of Soviet work in the field, and had reduced the expected operational lifetime of the U-2, knowing that it would become vulnerable to these missiles as they were improved. Flight Valykrie1 Octoberp.

Monday, 16 NovemberAugusta, Georgia, 8: Convair B Hustler Aerograph 4. It also had a smaller bombload and shorter range. Centennial of Flight Commission, Flying higher and faster made it more difficult for both; higher speeds allowed the bomber to fly out of range of the weapons more quickly, while higher altitudes increased the time needed for fighters to climb to the bombers, and greatly increased the size of the AAA weapons needed to reach those altitudes.

Kennedy ‘s campaign was that Eisenhower and the Republicans were weak on defense, and pointed to the B as an example. However, the aircraft would be flying as much as four times vqlkyrie fast.

Prototypes, X-Planes and Experimental Aircraft. In this low-level penetration role, the B offered little additional performance over the B it was meant to replace, while being far more expensive with shorter range. Al White XB pilot ejected, sustaining serious injuries, including the crushing of his arm by the closing clamshell-like escape crew capsule moments prior to ejection.

Office of Air Force History, Joint Chiefs of Staff 8 Report. Congress had also continued B appropriations in an effort to resurrect bomber development. An interceptor flying at normal altitudes would be effectively blind to bombers far below it. Redesignated A-series B B The XBs were intended to be used for the advanced study of aerodynamicspropulsionand other subjects related to large supersonic transports. From the mids, there was interest in using nuclear-powered aircraft in the bomber role.
