   The An-77 is a new proposed Ukrainian military airlifter, that is currently being developed. This project is also referred as the An-188. It is a further development of the An-70, which was a joint project with Russia. In 2006 because of economic problems and tough political relationship between Russia and Ukraine, Russia left the An-70 project in favor to indigenous Il-76MF and Il-476 transports. For a number of years the future of the An-70 project was uncertain due to the lack of funding and orders. In 2009 Russia signed a deal with Ukraine to renew development of the An-70 and reportedly resumed funding. During the same year it was announced that 2 An-70 aircraft will be built for Ukrainian air force. The type was officially adopted in 2015. However due to Russian military actions in Ukraine and annexation of Crimea, the joint project with Russia was stopped and the An-70 never reached series production. Antonov design bureau completed the aircraft on their own using Western components instead of Russian. Prototype of the An-77 was first publicly revealed in 2018. Though it was basically on of the previous Ukrainian An-70 with the "An-70" designation on the fuselage painted over. Due to funding problems currently it is impossible to start production of this aircraft for Ukrainian air force. The An-77 is being proposed for export. It is even being proposed for the US to fit the gap between their C-130J Super Hercules and C-17 Globemaster III. However judging from the previous Antonov designs it is unlikely that this Ukrainian aircraft will achieve significant sales.

   The new Ukrainian aircraft is slightly larger, than the European Airbus A400M, and can carry more load. However it is considerably smaller than the Boeing C-17 Globemaster III. The An-77's pressurized hold will have an inbuilt cargo-handling system. It will be able to carry around 300 troops or racks for around 200 litters as alternatives to cargo, vehicles or even helicopters. Its maximum payload capacity is around 35-47 t. The An-77 will be capable of airdroping individual items up to a limit of 20 000 kg. Range with maximum cargo will be around 3 000 km. This transport plane will be capable of carrying 20 t of cargo over a distance of around 6 000 km. Maximum service range will be around 8 000 km.

   The An-77 is planned to be a turbojet version of the An-70, which utilized propfan engines with contra-rotating propellers. It is planned that the An-77 will be powered by CFM International CFM56-5A1 turbojet engines. These engines are used on Airbus A320 commercial passenger jet airliner. So these engines are durable, reliable, widely available and easily serviceable.

   The previous An-70 used Russian avionics, chassis, and a number of other components. The new An-77 is planned to have no Russian components and instead will be fitted with Western avionics.

   The An-77 is a dedicated military machine, that can take off and land using short and unprepared landing strips, as well as from poorly equipped airfields that have no special ground facilities. It is capable of landing on soft ground and even snow. Some sources report, that take of run of this aircraft will be as short as 350 meters.
