The Antonov An-178 (Ukrainian: Антонов Ан-178) is a short-range medium-airlift military transport aircraft designed by the Ukrainian Antonov company and based on the Antonov An-158 (An-148-200). It was announced on 5 February 2010, rolled out on 16 April 2015 and the first flight was on 7 May 2015.[3][4][5]

The An-178 is proposed to replace outdated aircraft like the Antonov An-12, Antonov An-26 and Antonov An-32.[6] The aircraft will have avionics suite similar to the An-148, and will use Progress D-436-148FM engines.[7]

The An-178 is a potential competitor for the Alenia C-27J Spartan from Italy, EADS CASA C-295 from Spain, Lockheed Martin C-130J from the United States, Embraer KC-390 from Brazil and the Ilyushin Il-214 from the Russian Federation.[8] The company plans to build more than 200 of the aircraft.[9]

On 18 December 2015, Antonov and Тaqnia Aeronautics signed a Memorandum to deliver 30 An−178s to the Royal Saudi Air Force. Taqnia's President, Ali Mohammed Al−Ghamdi, noted that the An-178 had been selected because "its price and low operational costs are important advantages in comparison with other airplanes of this class".[10][11]

An-178 is a high-wing transport aircraft with moderately swept wing, winglets and a T-tail. The airframe is made of aluminium alloys and composite materials. The fuselage is semi-monocoque with a circular cross-section. The retractable landing gear consists of two main wheel bogies and a single nose wheel. The flight control system is dual duplex fly-by-wire system, consisting of two parts: FCS-A and FCS-B, each of which is responsible for two control channels. The flight control surfaces include ailerons near the wing tips, four control spoilers, six lift-dump/speed-brake spoilers, rudder and elevators, with an emergency mechanical cable back-up system. The powerplant consists of two Progress D-436-148FM turbofan engines, mounted on pylons under the wings and an auxiliary power unit.[7] It can shift 18 tonnes over 1,000 km, or 10 tonnes over 4,000 km.[12]

The wing outer panels (including winglets), front fuselage with cockpit and nose wheel leg come from the An-158. The cargo hold is slightly enlarged, and there is an extra pair of main-wheels on each side.[13] The aircraft made its Western debut at the 2015 Paris Air Show.
