Re: Vought A-7 Corsair II
It was the first U.S. aircraft to have a modern [Vous devez être inscrit et connecté pour voir ce lien], (made by [Vous devez être inscrit et connecté pour voir ce lien]), now a standard instrument, which displayed information such as dive angle, airspeed, altitude, drift and aiming reticle.
The integrated navigation system allowed for another innovation – the projected map display system (PMDS) which accurately showed aircraft position on two different map scales.

Re: Vought A-7 Corsair II
The A-7 had a fast and smooth development. The YA-7A made its first flight on 27 September 1965, and began to enter Navy squadron service late in 1966.
The first Navy A-7 squadrons reached operational status on 1 February 1967, and began combat operations over [Vous devez être inscrit et connecté pour voir ce lien] in December of that year.

The A-7's integrated weapons computer provided highly accurate bombing with [Vous devez être inscrit et connecté pour voir ce lien] of 60 ft (20 m) regardless of pilot experience.
When Vought technical representatives were available to "tweak" the inertial systems, the CEP was often less than five meters for experienced fleet aviators.
The inertial navigation system required a mere 2.5 minutes on the ground for partial (coarse) alignment, a big improvement over 13 minutes required in [Vous devez être inscrit et connecté pour voir ce lien].

For newly manufactured E models, the A-7 required only 11.5 [Vous devez être inscrit et connecté pour voir ce lien] of maintenance per mission resulting in quick turnaround and high number of combat-ready aircraft.
However, after several years of exposure to the harsh marine conditions aboard aircraft carriers, the maintenance hours per sortie were often twice this amount.

Re: Vought A-7 Corsair II
The A-7 offered a plethora of leading-edge avionics compared to contemporary aircraft.
This included data link capabilities that, among other features, provided fully "hands-off" carrier landing capability
when used in conjunction with its approach power compensator (APC) or auto throttle.

Re: Vought A-7 Corsair II
Other notable and highly advanced equipment was a projected map display located just below the radar scope.
The map display was slaved to the inertial navigation system and provided a high-resolution map image of the aircraft's position superimposed over TPC/JNC charts.

Moreover, when slaved to the all-axis auto pilot, the inertial navigation system could fly the aircraft "hands off" to up to nine individual way points.
Typical inertial drift was minimal for newly manufactured models and the inertial measurement system accepted fly over, radar, and TACAN updates.

Improved versions
Secretary of Defense [Vous devez être inscrit et connecté pour voir ce lien] prodded the Air Force to adopt not only the hugely successful F-4, but also the Navy's A-7 Corsair as a low-cost follow-on to F-105s until the troubled [Vous devez être inscrit et connecté pour voir ce lien] came online, and as a close-air support replacement for [Vous devez être inscrit et connecté pour voir ce lien].

On 5 November 1965, the USAF announced that it would purchase a version of the A-7, designated the A-7D, for [Vous devez être inscrit et connecté pour voir ce lien].
The Air Force ordered the A-7D with a fixed high speed refueling receptacle behind the pilot optimized for the [Vous devez être inscrit et connecté pour voir ce lien]'s flying boom rather than the folding long [Vous devez être inscrit et connecté pour voir ce lien] of the Navy aircraft.

Re: Vought A-7 Corsair II
The most important difference from the preceding Navy versions was the adoption of the [Vous devez être inscrit et connecté pour voir ce lien] turbofan, a license-built version of British Rolls-Royce Spey.
With 14,500 lbf (64.5 kN) of thrust, the engine offered a considerable boost in performance.
The [Vous devez être inscrit et connecté pour voir ce lien] cannon was selected in place of the twin single-barrel 20 mm cannon. In addition, avionics were upgraded.

The YA-7D prototype with TF30 flew on 6 April 1968, with the first TF41 aircraft taking to the air on 26 September 1968.
The aircraft were later updated to carry the [Vous devez être inscrit et connecté pour voir ce lien] laser spot tracker to add the capability to drop guided bombs.
A total of 459 were built and assigned to tactical fighter wings of the [Vous devez être inscrit et connecté pour voir ce lien] (TAC).
