Re: Convair F-102 Delta Dagger
The redesign entailed lengthening the fuselage by 11 ft (3.35 m) and "pinched" at the mid section (dubbed the "[Vous devez être inscrit et connecté pour voir ce lien] configuration"), with two large fairings on either side of the engine nozzle, with revised intakes and a new, narrower canopy.
A more powerful model of J57 was fitted, and the aircraft structure was lightened.

The first revised aircraft, designated YF-102A flew on 20 December 1954, 118 days after the redesign started, exceeding Mach 1 the next day.[Vous devez être inscrit et connecté pour voir ce lien]
The revised design demonstrated a speed of Mach 1.22 and a ceiling of 53,000 ft (16,154 m), which was sufficient for the Air Force to allow production of the F-102.

The production F-102A had the Hughes MG-3 fire control system, later upgraded in service to the MG-10.
It had a three-segment internal weapons bay under the fuselage for [Vous devez être inscrit et connecté pour voir ce lien].
Initial armament was three pairs of [Vous devez être inscrit et connecté pour voir ce lien] (Later re-designated as AIM-4) Falcon missiles, which included both [Vous devez être inscrit et connecté pour voir ce lien] and [Vous devez être inscrit et connecté pour voir ce lien] variants.

The doors of the two forward bays each had tubes for 12 [Vous devez être inscrit et connecté pour voir ce lien] rockets (for a total of 24) with initially 2 in (5.1 cm) being fitted and later 2.75 in (70 mm) replacing them.
The F-102 was later upgraded to allow the carriage of up to two [Vous devez être inscrit et connecté pour voir ce lien] Nuclear Falcon missiles in the center bay.

Re: Convair F-102 Delta Dagger
Because of the changes that had to be made in redesigning the aircraft with the area rule in mind, the ambitious plan to manufacture the production aircraft on the prototype tooling had to be abandoned; two-thirds of the 60,000+ pieces of tooling had to be scrapped or heavily modified.

The F-102 received several major modifications during its operational lifetime, with most airframes being retrofitted with infrared search/tracking systems, radar warning receivers, transponders, backup artificial horizons, and improvements to the fire-control system

A proposed close-support version (never built) would have incorporated, in addition, an internal [Vous devez être inscrit et connecté pour voir ce lien], an extra two [Vous devez être inscrit et connecté pour voir ce lien] for bombs (in addition to the two underwing pylons for [Vous devez être inscrit et connecté pour voir ce lien] that were fitted to all production F-102s), bigger internal fuel tanks, and an [Vous devez être inscrit et connecté pour voir ce lien] probe.[Vous devez être inscrit et connecté pour voir ce lien]

Re: Convair F-102 Delta Dagger
To train F-102A pilots, the TF-102A trainer was developed, with 111 eventually manufactured.
The aircraft was fitted with a side-by-side cockpit to facilitate ease of pilot training.
This required a redesign of the cockpit and nose incorporating a set of vortex generators on the top of the cockpit to prevent flow separation under certain circumstances, and repositioning of the intake ducts.

Despite the many changes, the aircraft was combat-capable, although this variant was predictably slower, only reaching subsonic speeds in level flight.

Re: Convair F-102 Delta Dagger
The F-102's intended successor was the improved F-102B "Ultimate Interceptor".
The design, which had the originally intended J67 engine replaced by a [Vous devez être inscrit et connecté pour voir ce lien] underwent so many aerodynamic changes including a variable-geometry inlet design that it essentially became an entirely new aircraft and
hence was redesignated [Vous devez être inscrit et connecté pour voir ce lien].
Convair would also use a delta-wing in the Mach 2 class [Vous devez être inscrit et connecté pour voir ce lien] bomber.
