Design and development
In June 1953, North American initiated an in-house study of advanced F-100 designs, leading to proposed interceptor (NAA 211: F-100BI denoting "interceptor") and fighter-bomber (NAA 212: F-100B) variants.

Concentrating on the F-100B, the preliminary engineering and design work focused on a tactical fighter-bomber configuration, featuring a recessed weapons bay under the fuselage and provision for six hardpoints underneath the wings.
Single-point refuelling capability was provided while a retractable tailskid was installed. An all-moving vertical fin and an automated [Vous devez être inscrit et connecté pour voir ce lien] was incorporated which permitted the aircraft to roll at supersonic speeds using [Vous devez être inscrit et connecté pour voir ce lien].
The flight control system was upgraded by the addition of pitch and yaw dampers.

The aircraft's most distinguishing feature is its dorsal-mounted Variable Area Inlet Duct (VAID).
While the VAID was a system unique to the F-107A, it was an early form of a variable geometry [Vous devez être inscrit et connecté pour voir ce lien] which automatically controlled the amount of air fed to the jet engine.

Although the preliminary design of the air [Vous devez être inscrit et connecté pour voir ce lien] was originally located in a chin position under the fuselage (an arrangement later adopted for the [Vous devez être inscrit et connecté pour voir ce lien]), the air intake was eventually mounted in an unconventional position directly above and just behind the cockpit.

The VAID system proved to be very efficient and NAA used the design concept on their [Vous devez être inscrit et connecté pour voir ce lien], [Vous devez être inscrit et connecté pour voir ce lien] aircraft and [Vous devez être inscrit et connecté pour voir ce lien] designs.

The air intake was in the unusual dorsal location as the USAF had required the carriage of an underbelly semi-conformal [Vous devez être inscrit et connecté pour voir ce lien].
The original chin intake caused a [Vous devez être inscrit et connecté pour voir ce lien] that interfered in launching this weapon.

It also severely limited view to the rear. Although this was not considered terribly important for a tactical fighter-bomber aircraft, it is characteristic of the era, when it was assumed air combat would be via [Vous devez être inscrit et connecté pour voir ce lien] exchanges outside visual range.

In August 1954, a contract was signed for three prototypes along with a pre-production order for six additional airframes.

Designation and names
Extensive design changes resulted in its redesignation from F-100B to F-107A before the first prototype flew.
The F-107 was never given an official name, but was sometimes informally called the "Super Super Sabre"[Vous devez être inscrit et connecté pour voir ce lien]referring to North American's earlier fighter design, the F-100 Super Sabre.

The flight crews referred to it as the "man eater", in reference to the position of the air intake directly above the cockpit.[Vous devez être inscrit et connecté pour voir ce lien]
The designation "F-107A" was the only one assigned to the aircraft,[Vous devez être inscrit et connecté pour voir ce lien][Vous devez être inscrit et connecté pour voir ce lien]though "YF-107A" is often used in publications.[Vous devez être inscrit et connecté pour voir ce lien]

Operational history
The first F-107A (s/n 55-5118) with North American's chief test pilot Bob Baker at the controls, made its initial flight on 10 September 1956, attaining Mach 1.03.
Although successfully carrying out its flight, the brake chute did not deploy, which resulted in a "hot" landing with the nose gear strut breaking.
The aircraft first achieved Mach 2 in tests on 3 November 1956.

At the conclusion of the F-107A's successful test program, the Tactical Air Command decided to hold a fly-off competition between the F-107A and the [Vous devez être inscrit et connecté pour voir ce lien] which was designed to same mission requirements and used the same engine.
Although the competition was close, the F-105 was selected as the new standard TAC tactical fighter.
The three F-107A prototypes were relegated to test flying while the pre-production order was cancelled.
