The TB-58A Trainer

The single-pilot configuration of the B-58, along with its high performance and its new flight characteristics (in particular, the nose-high landing and takeoff attitudes characteristic of a delta-winged aircraft) led to a requirement for a training version of the Hustler. It was decided not to build new airframes for this project, but rather to convert airframes from the original test batch of 30 aircraft to trainer configuration. On February 25, 1959, the Air Force first authorized the conversion of four early test B-58As to the training configuration under the designation TB-58A. The TB-58A program was formally approved on September 15, 1959.

In the TB-58A, the pilot trainee sat in the forward station. The second crew station was modified to accommodate an instructor pilot who was afforded with the necessary flight controls for in-flight instruction and safety. This included a set of conventional flight controls which were mechanically linked to those in the front cockpit. The instructor pilot's seat was offset to starboard by ten degrees to permit better forward vision. The third station was usually occupied by a pilot requiring proficiency training.

Externally, the TB-58A differed from the B-58A in having additional windows in the second cockpit area and a large window in the second overhead hatch to give the instructor pilot sitting in the second crew station with a better view. The instructor's compartment was completely sealed off from that of the student in the front cockpit, although a split transparency permitted forward view. During flight, the occupants of the second and third stations could change places via the crawlspace. All of the tactical equipment was removed - there was no autopilot, no primary navigation system, no bombing system, no defensive electronic countermeasures system, and no active defense system.

The first TB-58A conversion was carried out on 55-0670. It was completed in February of 1960 and carried out its first test flight on May 10, 1960. The first TB-58A was delivered to the Air Force in August of 1960.

A total of eight TB-58As were eventually created. No TB-58A was ever lost due to an accident.
