Question: AN/APG-79 was an improvement over the the specialized version of what previous aircraft?

<P0-S0>  The EA-18G replaced the Northrop Grumman EA-6B Prowlers in service with the United States Navy. <P0-S1> The Boeing EA-18G Growler is an American carrier-based electronic warfare aircraft, a specialized version of the two-seat F/A-18F Super Hornet. <P0-S2>  The Growler's electronic warfare capability is primarily provided by Northrop Grumman. <P0-S3>  The EA-18G began production in 2007 and entered operational service with the US Navy in late 2009. <P0-S4>  Australia has also purchased twelve EA-18Gs, which entered service with the Royal Australian Air Force in 2017. <SEP> <P1-S0> The Goupy No.1, a.k.a. Goupy I bis was an experimental aircraft built in France during 1908, which on 5 September that year became the first French triplane to fly. <P1-S1>  It was designed by Ambroise Goupy and built by Aéroplanes Voisin. <P1-S2>  Unlike previous aircraft built by Voisin, which had been pusher biplanes with a front elevator, the Goupy No.1 was a tractor triplane, with the ends of the wings connected by Voisin's characteristic "side curtains". <P1-S3>  The tailplane was a Hargrave cell in line with contemporary Voisin practice, with the addition of a pair of small moving elevators mounted on the leading edge of the outer surfaces and a central rudder. <P1-S4>  The undercarriage consisted of a single wheel mounted below the wing and a tailwheel. <P1-S5>  As originally constructed, the middle wing was mounted in a mid-wing position on the fuselage, with the top and bottom wings clear of the fuselage, and power was provided by an Antoinette engine. <P1-S6>  The design was later revised so that the bottom wing was mounted at the base of the fuselage, the middle wing to the top of the fuselage, and top wings clear of it. <P1-S7>  At the same time, the engine was changed to an Anzani of similar power and the wings extended outboard of the side curtains, and the single central mainwheel replaced by a pair of wheels. <SEP> <P2-S0>  The beam of the AESA radar provides nearly instantaneous track updates and multi-target tracking capability. <P2-S1>  The APG-79 AESA uses transmit/receive (TR) modules populated with Gallium arsenide Monolithic microwave integrated circuits. <P2-S2>  In the F/A-18E/F, the radar is installed in a slide-out nose rack to facilitate maintenance. <P2-S3> The AN/APG-79 Active electronically scanned array (AESA) radar is a new development for the United States Navy's F/A-18E/F Super Hornet and Boeing EA-18G Growler aircraft, providing a high level of aircrew situational awareness. <SEP> <P3-S0> The Nieuport-Delage NiD 39 was an airliner produced in France in the late 1920s, developed from the NiD 38. <P3-S1>  The airline "Compagnie Aérienne Française" had purchased four examples of the previous aircraft and ordered an improved version with greater passenger capacity from the manufacturer. <P3-S2>  Like its predecessor, the NiD 39 was a single-bay biplane of conventional design with an enclosed cabin its passengers and an open cockpit for the pilot. <P3-S3>  However, while the NiD 38 could only carry two passengers, the NiD 39 could carry four. <P3-S4>  CAF also specified the engine to be used – the Armstrong Siddeley Lynx – although the first eight examples produced flew with the same Hispano-Suiza engine that had powered the NiD 38. <P3-S5>  The airline operated around thirty examples on routes between western European cities until 1932.
