* '''''Izdeliye F''''' – The in-house designation for the An-2NAK observation aircraft which was later re-designated An-2K and/or An-2F.<ref name = "An-2">{{cite book |author1-last=Gordon |author1-first=Yefim |author2-last=Komissarov |author2-first=Dmitry |title=Antonov An-2 |publication-place=Midland |publisher=Hinkley |date=2004 |isbn=1-85780-162-8}}</ref>
* '''''Izdeliye K''''' – A prototype weather reconnaissance/research aircraft with an observers cockpit immediately forward of the fin above the rear fuselage. First flown on 21 March 1948 'Izdeliye K' was found to be under-powered and unable to carry out its intended mission at high altitude, the aircraft was abandoned after a landing accident in October 1948. The concept was resurrected in 1954 as the 'An-2ZA' / 'An-6 Meteo'.<ref name = "An-2"/>
* '''''Izdeliye T''''' – The original design concept originated at [[OKB-153]] in Novosibirsk.
* '''''Izdeliye Sh''''' – The in-house designation for the 'Izdeliye T' (presumably to confuse spies or infiltrators) design project at Novosibirsk.<ref name = "An-2"/>
* '''SKh-1''' – the original designation of the An-2 used during the design phase of the project before the OKB had been named after Antonov.<ref name = "An-2"/>
* '''An-2A''' – Developed from the An-2T for use as a Balloon interceptor to intercept reconnaissance balloons from, US intelligence assets, over-flying the USSR. The prototype was converted from a Kiev built An-2 (c/n 110347315) using the Turbo-charged Ash-62IR/TK of the 'An-6 Meteo' and a combined searchlight/gun turret mounted on top of the rear fuselage, which mounted either a single [[Gryazev-Shipunov GSh-23]] 23&nbsp;mm calibre twin-barrelled cannon or a single [[Afanasev A-12.7|Afanas'yev A-12.7]] 12.7&nbsp;mm calibre heavy machine-gun.<ref name = "An-2"/>
* '''An-2E''' (''Ekranoplan'' – wing in ground effect)[[File:An-2 converted into WIG (Rybachy, Kaliningrad Oblast - 2006 08 15).jpg|thumb|The An-2E prototype ekranoplan]] (first use of the designation) – One of a series of projects from the early 1970s for WIG ([[Ground effect vehicle|Wing In Ground]] effect) derivatives of the An-2, designed at the TsLST (''Tsentral'naya Laboratoriya Spasatel'noy Techniki'' – central laboratory for new types of rescue equipment).
* '''An-2E''' (second use of the designation) – An [[Ekranoplan]] conversion ({{langx|ru|Ан-2Э}}) of an An-2P (RA-84692). The fuselage was retained and a large trapezoidal monoplane wing having extended wingtips with approx 45° dihedral, attached to the lower wing attachment points. The prototype conversion was intended to be a floatplane; however, its first public appearance was as a landplane with the standard An-2 undercarriage. Jointly developed by the Moscow Aviation Institute, MARZ (''Moskovskiy Aviaremontnyy Zavod'' – Moscow Aircraft Overhaul Plant) and The TSZP-Saturn research institute the An-2E was also known as EA-00078. Power was supplied by the standard ASh-62IR radial engine with AV-2 propeller, but production versions were intended to be powered by automotive diesel engines of around {{cvt|580|hp|order=flip|}}.<ref name = "An-2"/><ref name="An-2e">{{cite web|url=http://ruslet.webnode.cz/technika/ruska-technika/ekranoplany/mai/an-2e/|title=MAI An-2e|publisher=Ruslet|access-date=2015-04-10|archive-url=https://web.archive.org/web/20150410230428/http://ruslet.webnode.cz/technika/ruska-technika/ekranoplany/mai/an-2e/|archive-date=2015-04-10|url-status=live}}</ref>
* '''An-2F''' – Developed concurrently with the An-2 prototype, 'Izdeliye F' was an experimental artillery-observation aircraft with a twin-tail, ventral observer's position and dorsal defensive machine-gun position. The initial service designation of An-2NAK was changed to An-2F once post test flight modifications had been carried out. Two prototypes were built, with the first completed in the summer of 1948, but flight testing was delayed to April 1949 due to the need to incorporate modifications called up from the standard An-2 flight test programme. The flight test of the An-2F showed that the aircraft met all the requirements of the specification, but helicopters were demonstrating that they could perform the artillery correction role without the need to provide fixed base airstrip for them to operate from, thus the An-2F was not proceeded with and the two prototypes were retained by the Antonov bureau for hack duties with one later serving as a flying wind tunnel to investigate para-dropping from the [[Antonov An-8]] twin-turboprop transport.<ref name = "An-2"/>
* '''An-2F''' (second use of designation) – A VTOL project with vertical thrust to be provided by a Mikulin AM-9 turbojet in the rear fuselage.<ref name = "An-2"/>
* '''An-2F''' (third use of the designation) – A proposed photo-mapping aircraft project, from the early 1990s, similar to the An-2PF equipped with one of five alternate cameras. Overall control was to have been by IBM 286 computer and the camera could be augmented or replaced by a thermal imaging system, Infra-Red imaging system, AP-6E autopilot, LDI-3 laser rangefinder and/or a GPS global positioning system.<ref name = "An-2"/>
* '''An-2G''' (a.k.a. '''An-2Geo''') – During 1974 WSK-Mielec developed a geo-physical survey aircraft for the Polish State Geophysical Survey Agency (''Państwowe Przedsiębiorstwo Poszukiwań Geofizycznych''), with equipment for measuring magnetic fields, radiation and other instruments for prospecting. Adapted to fly in tropical latitudes at low altitude the 'An-2G' could fly for six hours and two were used for survey work in [[Nigeria]] in 1974.<ref name = "An-2"/>
* '''An-2LP''' (''Lesopozharnyy'' – forest firefighter) – A single prototype converted from an An-2V floatplane, with 630 litre(139 Imp.Gal.) water tanks in each float for dropping on fires. The water tanks could be re-filled in flight, as the aircraft skimmed the surface of suitable bodies of water. Prior to dropping an alkaline wetting agent (NP-1 Sulphanol) was added to the water which was released through the scoops which also picked up the water to refill the tanks. Ten production aircraft were built seeing service in the Siberian and Far East regions of the USSR.<ref name = "An-2"/>
