BAe delivered the first GR.3 transponder modification kits only eight days after the MOD's request. Technicians then installed each transponder and its antenna in an access panel under the aircraft's nose.15 The speed with which BAe produced these kits was typical of the cooperation between industry and government during the crisis.plataforma inercial:Another example of industry's commitment was the development by Ferranti Ltd. of support equipment to align the GR.3's inertial navigation-attack system (INAS). The INAS's accelerometers provide the pilot information about altitude, navigation, and bombing by calculating velocity and changes in position. To provide accurate data, the INAS must be properly leveled and aligned before takeoff.16 Sea Harriers have a different navigation system that compensates for the ship's movement, but there was no time to install this system in the GR.3. Faced with the impending GR.3 deployment to the carriers, MOD requested technical help from Ferranti.17Ferranti officials discussed the project on 15 April and received the go-ahead from MOD the next day. Two days later a design for the Ferranti inertial rapid alignment equipment (FINRAE) was complete. FINRAE--developed and delivered in only 18 days--is a lightweight, trolley-mounted, battery-powered platform that can interface with the GR.3's INAS and feed it positional data. The acquisition of FINRAE's trolley is typical of the speed with which the project was completed. The manufacturer originally quoted a delivery time of six months, but after being told why the trolley was needed, delivered in the next morning.18 Because the FINRAE's navigational data was not as accurate as information available from airfields, the GR.3s used FINRAE for attitude information only. This restriction forced the crew to use visual navigation for weapons delivery during low-level operations. After the conflict, FINRAE was further tested and eventually produced accurate and timely alignments.19modificacion para los Sidewinders:Lastly, the GR.3 had to be modified to carry the AIM-9 Sidewinder missile. On 16 April MOD indicated that this modification--the most involved of all the changes to the GR.3--would have to be completed in two weeks. By 21 April BAe and RAF engineering officers had developed a conversion plan, and MOD approved it the following day. The first conversion was completed at RAF Wittering on 28 April.20 Adapting the GR.3 to carry the AIM-9 required technicians to install an electronic relay box in the rear equipment bay and a missile control panel in the cockpit. They made only a few changes to the existing armament wiring in the wings leading to the outer pylons but modified an adapter that allowed the missile launch rail to be attached to the pylons. After 18 AI.M-9 modification kits were produced, technicians modified 11 aircraft initially.21Several factors contributed to the speed and success of the AIM-9 program. The RAF, plans in hand, had asked for similar modifications but funding was not forthcoming. Further, the program benefited from the exceptional cooperation and joint effort of the BAe design team from Kingston, the RAF Engineering Wing at Wittering, and officials from the test establishments at Farnborough and Boscombe Down. Lastly, the need for additional British aircraft in the South Atlantic tended to overcome previous funding difficulties.Six modified GR.3s and eight Sea Harriers flew to Ascension Island where they were loaded on board a containership, eventually joining the task force on 18 May. Before the hostilities ended, four additional modified GR.3s reached the task force after in-flight refueling by Victor tanker aircraft.22 Despite the intense effort to modify the GR.3 to carry the AIM-9, these missiles were off-loaded after their first operational mission because the Argentine air threat to the Harriers had not materialized as anticipated.23 The success of Sea Harriers armed with AIM-9s in aerial combat persuaded Argentina to refrain from risking any more aircraft.24 The GR.3s were therefore employed in low-level ground attacks and reconnaissancelos tiempos de ellos en tiempos de guerra no dejan de sorprender, no solo el tamaño de sus fuerzas sino principalmente el poseer una industria propia les daban una ventaja mas que significativa.simultaneamente a los Harrier, modificaban a los Nimrod y Hercules.de ser necesario, y de tomarse la desicion politica adaptarse a otra plataforma no les hubiera llevado un tiempo tan largo como para tener que suspender las operaciones.</blockquote>
