The Republic RC-3 Seabee is an all-metal amphibious sports aircraft designed by Percival Spencer and manufactured by the Republic Aircraft Corporation. The RC-3 Seabee was designed by Percival Hopkins "Spence" Spencer. An aviation pioneer, he built his first hang glider in April 1911 at the age of 17 from plans he found in a Popular Mechanics magazine. On May 15, 1914, Spencer made his first powered flight in a Curtiss flying boat. In 1937, he joined Sikorsky engineer Vincent A. Larsen to design their first and only amphibious aircraft, the Spencer-Larsen SL-12C. Development of the plane progressed slowly and in September 1940 Spencer left the partnership to form his own company. His resulting design was the Spencer S-12 Air Car Amphibian. Construction of the S-12 began on March 1, 1941 and the small, two-seat S-12 prototype, registered NX29098, made its first flight on August 8, 1941. The S-12 was a fabric covered amphibian with a unique boxlike forward cabin; a high wing with a two-bladed propeller in pusher configuration; and a long, slender tail boom. In order to meet the anticipated postwar demand for civilian light aircraft, Republic endeavored to build the Seabee as inexpensively as possible, while still retaining reasonable performance and range. A lot of thought went into eliminating what were at the time termed as 'airplane frills,' resulting in a strong product built with as few parts as possible. For example, Seabees as built did not have ribs in the wings; instead, the heavy corrugated aluminum sheet which formed the skin provided the necessary stiffness. Republic was also willing to buy components in volume, which lowered costs further. On November 22, 1945, the prototype RC-3 (NX87451) came off the assembly line at Republic's factory in Farmingdale, New York and on December 1 made its first flight in Farmingdale with Spencer at the controls. On December 27, 1945, Republic Aviation purchased Aircooled Motors, manufacturers of the Franklin engine, to supply and build engines for the RC-3 Seabee. In March, 1946, the first production RC-3 Seabee was completed (NC87457, formerly NX87457, and on July 25, 1946 the first Seabee (NC87463, production #13) was delivered at the Republic factory to J.G. (Tex) Rankin of Rankin Aviation Industries of Tulare, California. For more information on the developmment, production and operational history of the Seabee, click here.

(Note: This profile will be moved to Recreational (3-Axis) when the revised weight limitations are introduced.) The APM 20 Lionceau is a two-seat very light aircraft manufactured by the French manufacturer Issoire Aviation. Despite its classic appearance, it is entirely built from composite materials, especially carbon fibers. Designed by Philippe Moniot and certified in 1999 (see EASA CS-VLA), this very light (400 kg empty, 634 kg loaded) and economical (80 PS engine) aircraft is primarily intended to be used to learn to fly, but also to travel with a relatively high cruise speed (113 knots). A three-seat version, the APM 30 Lion, was presented at the 2005 Paris Air Show. See also the profile for the four-seat AMP 40 Simba in General Aviation (Single Engine).

The Israel Aircraft Industries Kfir (Hebrew: כְּפִיר, "Lion Cub") is an Israeli all-weather multirole combat aircraft based on the French Dassault Mirage 5, with Israeli avionics and an Israeli-built version of the General Electric J79 turbojet engine. The Kfir programme originated in the quest to develop a more capable version of the IAI Nesher, which was already in series production. After General De Gaulle embargoed the sale of arms to Israel, the IAF feared that it might lose qualitative superiority over its adversaries in the future, which were receiving increasingly advanced Soviet aircraft. The main and most advanced type of aircraft available to the IAF was the Mirage, but a severe problem developed due to the Mirage fleet's depletion due to attrition after the Six-Day War. Domestic production would avoid the problem of the embargo completely; efforts to reverse engineer and reproduce components of the Mirage were aided by Israeli espionage efforts to obtain technical assistance and blueprints from third party Mirage operators. Two powerplants were initially selected for trials, the General Electric J79 turbojet and the Rolls-Royce Spey turbofan. In the end, the J79 was selected, not least because it was the same engine used on the McDonnell Douglas F-4 Phantom II, which the Israelis began to acquire from the United States in 1969, along with a license to produce the J79 themselves. The J79 was clearly superior to the original French Atar 09, providing a dry thrust of 49 kN (11,000 lbf) and an afterburning thrust of 83.4 kN (18,750 lbf). In order to accommodate the new powerplant on the Mirage III's airframe, and to deliver the added cooling required by the J79, the aircraft's rear fuselage was slightly shortened and widened, its air intakes were enlarged, and a large air inlet was installed at the base of the vertical stabilizer, so as to supply the extra cooling needed for the afterburner. The engine itself was encased in a titanium heatshield. A two-seat Mirage IIIBJ fitted with the GE J79 made its first flight in September 1970, and was soon followed by a re-engined Nesher, which flew in September 1971. An improved prototype of the aircraft, with the name Ra'am B ("Ra'am" means "Thunder"; the "Ra'am A" was the Nesher),[3] made its first flight in June 1973. It had an extensively revised cockpit, a strengthened landing gear, and a considerable amount of Israeli-built avionics. The internal fuel tanks were slightly rearranged, their total capacity being increased to 713 US gal (2,700 L). For details of operational history, foreign service and the 12 variants, click here.

The PZL I-22 Iryda, otherwise known as the PZL M93 Iryda and PZL M96 Iryda, was a twin-engine, two-seat military jet trainer aircraft developed and produced by Polish aviation company PZL Mielec. Work started on what would become the Iryda in 1976 as a successor to the indigenously-developed TS-11 Iskra jet trainer. First flying on 3 March 1985, the type would have a protracted development, partly due to the initial unavailability of its PZL K-15 turbojet engines. The Polish Air Force received the first K-15-powered Irydras in May 1995. However, aircraft deliveries were complicated by disputes over cost and performance, leading to multiple announcements, policy reversals, and groundings of the type. A fatal accident involving the type on 24 January 1996 fuelled criticism and undermined support for the programme. In 1996, an agreement was struck to upgrade the existing aircraft to a new standard, flight testing of which commenced the following year. However, relations between PZL Mielec and the Polish Defense Ministry became so poor over the programme that legal action was initiated while the Iryda itself languished. In the late 1990s Polish Government support for the programme was withdrawn, and the handful of delivered aircraft were stored. Despite attempts to revive the programme by PZL Mielec, no orders have been forthcoming. Number built 17 including prototypes

In February of 2019, the Pakistan Air Force launched retaliatory airstrikes on Indian military installations at Indian Administered Jammu and Kashmir in response to India's violation of Pakistani airspace and the bombing of a wooded area at Balakot. While fighter jets from various PAF squadrons executed the airstrikes, Saab-2000 Erieye AWACS along with DA-20 EW supported them throughout the operation. The Erieye AEW&C mission system radar is an active, phased-array, pulse-doppler sensor that can feed an onboard operator architecture or downlink data (via an associated datalink subsystem) to a ground-based air defence network. The system employs a large aperture, dual-sided antenna array housed in a dorsal 'plank' fairing. The antenna is fixed, and the beam is electronically scanned, which provides for improved detection and significantly enhanced tracking performance compared with radar-dome antenna systems. Erieye detects and tracks air and sea targets out to the horizon, and sometimes beyond this due to anomalous propagation — instrumented range has been measured at 450 kilometres (280 mi). Typical detection range against fighter-sized targets is approximately 425 kilometres (264 mi), in a 150° broadside sector, both sides of the aircraft. Outside these sectors, performance is reduced in forward and aft directions. Other system features include: Adaptive waveform generation (including digital, phase-coded pulse compression); Signal processing and target tracking; track while scan (TWS); low side lobe values (throughout the system's angular coverage); low- and medium-pulse repetition frequency operating modes; frequency agility; Air-to-air and sea surveillance modes; and target radar cross-section display.

The Whisper X350 Generation II is a South African amateur-built aircraft, designed in 2015 and produced by Whisper Aircraft of Mossel Bay. The aircraft was developed from the 2004-designed Whisper Aircraft Whisper motorglider. The X350 Generation II is supplied as a kit for amateur construction. The X350 Generation II designation indicates a design top speed goal of 350 km/h (189 kn), with the larger engine fitted. The aircraft features a cantilever low-wing, a two-seats-in-side-by-side configuration enclosed cockpit that is 47.2 in (119.9 cm) wide, under an acrylic plastic articulated lift-up bubble canopy. It has fixed optionally tricycle landing gear or conventional landing gear and a single engine in tractor configuration. The aircraft is predominately made from vacuum-bagged, post-cured carbon fibre composites, with E-glass used for non-structural parts, including the engine cowling, aircraft fairings, wing and tail tips. The structure is 10% anodized aluminum and cadmium-plated steel, with the landing gear legs made from steel. The design's 26.17 ft (8.0 m) span wing has an area of 122 sq ft (11.3 m2) and mounts plain flaps and features a cruciform tail. The aircraft's recommended engine power range is 160 to 200 hp (119 to 149 kW) and standard engines used include the 160 hp (119 kW) Lycoming O-320, the 180 hp (134 kW) Lycoming O-360, the 200 hp (149 kW) Lycoming IO-390, or the 180 to 200 hp (134 to 149 kW) ULPower UL520i four-stroke powerplants. The fuel capacity is 32 U.S. gallons (120 L; 27 imp gal) in two fuselage tanks, although future production kits will have 63 U.S. gallons (240 L; 52 imp gal) in a wet wing. The design has a single centre console-mounted side-stick or optional individual centre stick controls. The ailerons are actuated via push rods, while the elevator has push rods to the tailcone and then cables. The rudder is cable-actuated. There is no elevator trim tab system, but it may be included as a future factory option. Evaluation flights indicated neutral longitudinal stability, however, reducing the need for one. The left seat is equipped with toe-brakes. The 51% compliant kit includes a mated fuselage and pre-closed wing structures. The aircraft can be constructed in a two-car garage. Construction time from the supplied kit is estimated by the manufacturer as 500 hours. The design as load factors of +6/-4 g, but is not designed for aerobatics. The instrument panel is made from aluminum. The seats and rudder pedals are independently adjustable. There are optional rear fuselage windows for improved visibility, LED navigation lights and strobe lights on the wing tips and tail. Lightning protection is a factory option. Tricycle gear variant.

Ion Aircraft is developing a line of light, two-seat (tandem) airplanes suitable for training, sightseeing, cross-country cruising, and generally having fun. All of Ion Aircraft's engineering is being done by AirBoss Aerospace of Reno, Nevada. The Ion 100 is a kit aircraft being designed from the ground up to be Light Sport Aircraft (LSA) compliant. The majority of the plane is carbon fiber/epoxy composite material. Specifically :- The cowl is fiberglass. Although it is very slightly heavier than carbon fiber would have been, the cowl is not structural and the fiberglass is much less expensive. The wings are bonded aluminum as the bonded aluminum process is actually calculated to be a little lighter than composite would have been.

The Saab 2000 is a twin-engined high-speed turboprop airliner built by Swedish aircraft manufacturer Saab. It is designed to carry 50–58 passengers and cruise at a speed of 665 km/h (413 mph). Production took place in Linköping in southern Sweden. The Saab 2000 first flew in March 1992 and was certified in 1994. The last aircraft was delivered in April 1999, a total of 63 aircraft being built. By October 2022, 27 Saab 2000s were in airline and military service. In December 1988, Saab decided to build a stretched derivative of its successful Saab 340 twin-turboprop regional airliner. The new aircraft was planned to meet a perceived demand for a high-speed 50-seat turboprop with good climb performance which could operate over short- and medium-range routes with similar block times to jet aircraft while retaining the efficiency provided by turboprop engines. The new airliner, called the Saab 2000, was formally launched in May 1989, with Saab already having firm orders for 46 aircraft and options for a further 147. The aircraft was assembled at Saab's Linköping factory, with major subcontractors including CASA, who built the aircraft's wings, Short Brothers, who built the rear fuselage and Valmet who built the aircraft's tail surfaces. The Saab 2000 first flew on 26 March 1992 and entered into scheduled airline service in September 1994, a few months after its certification by the Joint Aviation Authorities in March and the Federal Aviation Administration in April. The Saab 2000 has a 15% greater wingspan than the Saab 340, and being 7.55 metres (24 ft 9 in) longer can carry up to 58 passengers in a high-density layout and 50 with a more comfortable 32 inches (81 cm) seat pitch. The 2000 was the first commercial aircraft to use the Allison GMA 2100 turboprop engines, which are derated to 3,390 kW (4,550 shp) for the plane. One engine was mounted on each wing, as in the 340, with the engines placed further from the fuselage than those of the 340 to reduce cabin noise. The Dowty-Rotol propellers are 3.81 m (12.5 ft) in diameter, and they have a slow rotational speed of 1,100 rpm at takeoff and 950 rpm in cruise. The aircraft was designed to operate at a maximum cruise speed of Mach 0.62. Variants Saab 2000: 50–58 seat regional airliner.

The Heinkel He 162 Volksjäger (German, "People's Fighter") was a German single-engine, jet-powered fighter aircraft fielded by the Luftwaffe in World War II. Developed under the Emergency Fighter Program, it was designed and built quickly and made primarily of wood as metals were in very short supply and prioritised for other aircraft. Volksjäger was the Reich Air Ministry's official name for the government design program competition won by the He 162 design. Other names given to the plane include Salamander, which was the codename of its wing-construction program, and Spatz ("Sparrow"), which was the name given to the plane by the Heinkel aviation firm. The aircraft was notable for its small size; although almost the same length as a Bf 109, its wing was much shorter at 7.2 metres (24 ft) vs. 9.9 metres (32 ft) for the 109. Most distinctive was its top-mounted engine, which combined with the aircraft's ground-hugging landing gear allowed the engine to be easily accessed for maintenance. This made bailing out of the aircraft without hitting the engine difficult, and the He 162 is thus also notable as the first single-engine aircraft to mount an ejection seat in an operational setting. The small size left little room for fuel, which combined with the inefficient engine resulted in very low endurance on the order of 20 minutes, and it only had room to mount two autocannons, making it quite underarmed for the era. A series of fatal accidents during testing required a series of refinements that delayed the program, but the aircraft eventually emerged in January 1945 as an excellent light fighter. Although production lines were set up and deliveries began, the state of Germany by that time made the effort pointless. Of just less than 1,000 examples on the assembly lines, only about 120 were delivered to the airfields and most of those never flew, usually due to shortages of parts, fuel, and pilots. Small numbers were used in development squadrons and these ultimately saw combat in a few cases during April 1945, yet the He 162 also proved to be quite dangerous to its own pilots as its tiny fuel load led to a number of aircraft crashing off field, while additional losses were attributed to structural failure. Production was still ongoing when the conflict ended in May 1945. Numerous aircraft were captured by the Allied forces along with ample supplies of parts from the production lines. Eric Brown flew one just after the war and considered it a first-rate aircraft with few vices. Several He 162s have been preserved in museum collections around the world. for details of development and design, operational history and 10 variants, click here.

The Heinkel He 177 Greif (Griffin) was a long-range heavy bomber flown by the Luftwaffe during World War II. The introduction of the He 177 to combat operations was significantly delayed, by both problems with the development of its engines, and frequent changes to its intended role. Nevertheless, it was the only long-range, heavy bomber to become operational with the Luftwaffe during the war. The He 177 had a payload/range capability similar to that of four-engined heavy bombers used by the Allies in the European theatre. Work on the design began in response to a 1936 requirement, known as Bomber A, issued by the RLM for a purely strategic bomber. Thus the He 177 was intended originally to be capable of a sustained bombing campaign against Soviet manufacturing capacity, deep inside Russia. In contrast to its heavy payload and very wide, 30 metres (98 ft) planform, the specifications called for the design to have only two very powerful engines. To deliver the power required, the He 177 needed engines of at least 2,000 horsepower (1,500 kW). Engines of this type were new and unproven at the time. The Daimler-Benz DB 606 power system that was selected, in conjunction with its relatively cramped nacelles, caused cooling and maintenance problems, such that the powerplants became infamous for catching fire in flight,[3] and contributing to the He 177 gaining nicknames from Luftwaffe aircrew such as Reichsfeuerzeug ("Reich's lighter") or Luftwaffenfeuerzeug ("Air Force lighter"). The type matured into a usable design too late in the war to play an important role. It was built and used in some numbers, especially on the Eastern Front where its range was particularly useful. It is notable for its use in mass raids on Velikiye Luki in 1944, one of the late-war heavy bombing efforts by the Luftwaffe. It saw considerably less use on the Western Front, although it played a role during Operation Steinbock (the "Baby Blitz"), against the UK in 1944. A total of 1,169 were built.

The Miles M.57 Aerovan was a British twin-engined short-range low-cost transport aircraft designed and produced by Miles Aircraft. It was primarily used for freight and passenger services. Development of the Aerovan started during the latter years of the Second World War as an affordable freighter suitable for both civilian and military purposes. It was suited to austere operations, and possessed an atypically high payload capacity for its power output. Relatively large payloads, including a single car, could be transported by the aircraft, being loaded via its large clamshell freight door. While Miles intended to produce the Aerovan for the British Army as a wartime asset, development was put on hold by order of the Air Ministry until the end of the conflict. On 26 January 1945, the maiden flight of the Aerovan took place. Quantity production formally commenced during 1946, although customer demand exceeded the company's production capacity. The Aerovan was primarily flown by commercial operators, but was also operated by a number of military users. Numerous variants were developed, and further models were envisioned, including a flying boat model; however, production was halted as a result of the company's bankruptcy in late 1947. The Miles Aerovan was a twin-engined high-wing monoplane of plastic-bonded plywood construction with some spruce and metal parts. It had a fixed tricycle undercarriage, three vertical tail and rudder units, one central and two as tailplane endplates, the configuration being generally reminiscent of the Miles Messenger. The wing featured electrically-actuated flaps that could be adjusted to any angle, which were a recent innovation. On the ground, steering was achieved either by differential braking or differential operation of the throttles. The Aerovan had a relatively deep-sided forward fuselage, which necessitated the use of a large fin area. A pair of pilots were accommodated within a large clear perspex canopy which formed the front dorsal part of the pod, while the pod-shaped fuselage was lined with four or five circular windows on either side for use by passengers. Access to the cabin and cockpit was via a door on the starboard side. For additional comfort, amenities such as soundproofing were typically installed. The Aerovan's lifting capabilities were such that payloads could weigh up to one tonne, along with sufficient volume to enable the carriage of a typical family car, which could be loaded through the clamshell doors set to the rear. Various aspects of the Aerovan's configuration could be adjusted to meet customer demand; such alterations included the addition of skis for operations within snowy climates. The standard Aerovan was powered by a pair of Blackburn Cirrus Major piston engines; alternative powerplants included the de Havilland Gipsy Major and the Lycoming O-435, often necessitating the use of enlarged fins and rudders to cope with the increased power under all circumstances. By swapping the engines, the maximum speed could be increased by up to 20 mph and the rate of climb by up to 50 per cent.

The Miles M.17 Monarch was a British, light, touring aeroplane of the 1930s. It was a single-engine, three-seat, cabin monoplane with a fixed, tailwheel undercarriage. The last civil type produced by Phillips and Powis before the war, the Monarch was a development of their earlier Whitney Straight. Compared to its sibling. the Monarch had an enlarged fuselage, allowing provision of a third seat in part of what had been the luggage space. Eleven aircraft were built between 1938 and 1939, six of these to British customers, the rest going to export. On the outbreak of war five of the British-registered machines were impressed by the Air Ministry; one machine belonging to Rolls-Royce acquired camouflage paint but remained in its owner's service. All but one of these survived the war, though a Dutch-registered aeroplane (PH-ATP) was destroyed in the Luftwaffe raid on Schiphol on 10 May 1940. One aircraft, OY-DIO, was on the Danish register until 9 Sept. 1939 and owned by a Dane named Hagedorn. In the 1950s, one Monarch (G-AIDE) enjoyed some success as a racer in the hands of W.P. Bowles For the most part, the remaining Monarchs led uneventful but useful careers; a number survived into the Sixties. G-AFJU is displayed at the National Museum of Flight at RAF East Fortune near East Linton, Scotland.
