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

Context paragraphs:
Aero Boero AB-210: The Aero Boero AB-210 is an Argentine civil utility aircraft, a development of the AB-180 with improved performance delivered by a fuel-injected engine.  Unlike previous aircraft by this manufacturer, it also featured tricycle undercarriage, but retained the same general high-wing configuration.  Only a single prototype was built, first flying on 22 April 1971.

Messerschmitt M 24: The Messerschmitt M 24, otherwise known as the BFW M.24, was an airliner developed in Germany in the late 1920s as a further development in the series of designs produced by Messerschmitt, based on the M 18.  Like the M 18 and its follow-on, the M 20, it was a high-wing cantilever monoplane with a fully enclosed cabin and fixed tailwheel undercarriage.  It was slightly smaller than the M 20, seating only eight passengers instead of the ten that could be carried by the previous aircraft.

Avia BH-33: The Avia BH-33 was a biplane fighter aircraft built in Czechoslovakia in 1927.  It was based on the BH-21J which demonstrated promising results by combining the original BH-21 airframe with a licence-built Bristol Jupiter radial engine.  Other than the peculiar Avia hallmark of having an upper wing with a shorter span than the lower, it was utterly conventional, even featuring a tail fin for the first time in a Pavel Beneš and Miroslav Hajn design (previous aircraft had a rudder but no fin).

AN/APG-79: 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.  The beam of the AESA radar provides nearly instantaneous track updates and multi-target tracking capability.  The APG-79 AESA uses transmit/receive (TR) modules populated with Gallium arsenide Monolithic microwave integrated circuits.  In the F/A-18E/F, the radar is installed in a slide-out nose rack to facilitate maintenance.

Nieuport-Delage NiD 39: The Nieuport-Delage NiD 39 was an airliner produced in France in the late 1920s, developed from the NiD 38.  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.  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.  However, while the NiD 38 could only carry two passengers, the NiD 39 could carry four.  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.  The airline operated around thirty examples on routes between western European cities until 1932.

Boeing EA-18G Growler: 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.  The EA-18G replaced the Northrop Grumman EA-6B Prowlers in service with the United States Navy.  The Growler's electronic warfare capability is primarily provided by Northrop Grumman.  The EA-18G began production in 2007 and entered operational service with the US Navy in late 2009.  Australia has also purchased twelve EA-18Gs, which entered service with the Royal Australian Air Force in 2017.

Red Checkers: The Red Checkers was the aerobatic/precision flying Team of the Royal New Zealand Air Force.  The Checkers fly the Pacific Aerospace CT-4E Airtrainer.  Previous aircraft used were the CT4B and North American Harvard (T-6).  Until the year 1994 the Checkers were based at Wigram.  Aircraft used by the team had a nose painted in a red and white checkered pattern, but this has now been reduced to a small checkered stripe.

Goupy No.1: 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.  It was designed by Ambroise Goupy and built by Aéroplanes Voisin.  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".  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.  The undercarriage consisted of a single wheel mounted below the wing and a tailwheel.  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.  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.  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.

Carrier Strike Group 7: Carrier Strike Group Seven (CSG-7 or CARSTRKGRU 7) was a U.S. Navy carrier strike group active from October 2004 until 30 December 2011.  The strike group's antecendants included two previous aircraft carrier formations, Carrier Division Seven and Carrier Group Seven.  Its heritage thus includes the Second World War, the Vietnam War, and the Cold War, as well as the first and the second Persian Gulf wars, encompassing a total of 34 deployments to the Western Pacific Ocean and Persian Gulf.

Kayaba Ku-4: The Kayaba Ku-4 was a research aircraft built in Japan in 1940 to investigate the possibilities of tailless designs.  It followed designer Hidemasa Kimura's successful Ku-2 and Ku-3 designs for the Imperial Japanese Army.  While these previous aircraft had been gliders, however, the Ku-4 was to be a powered by a pusher engine.  It had a low, swept wing, and like the Ku-2, fins at the wingtips.
