F-105B Phase II Flight Evaluation
AIR FORCE FLIGHT TEST CENTER EDWARDS AFB CA
Pagination or Media Count:
The performance of the F-105B is superior to any fighter-bomber presently in service however, the aircraft has a large number of deficiencies. Although a maximum speed of 1.95 Mach number can be attained, poor acceleration characteristics provide little tactical utility from speeds above 1.8 Mach number. The specific range of the aircraft is approximately 20 percent less at 35,000 feet than estimated by the contractor. Both the longitudinal and lateral control systems are unsatisfactory. Structural failures which occurred during the test program, such as the boundary layer splitter and speed brake skin failures, must be investigated and action taken to prevent future occurrence. A major redesign will be required to correct cockpit deficiencies. Fixes for these and other unsatisfactory areas must be developed and incorporated before the aircraft can be considered acceptable for tactical use.
