the class of the An-70, one that had a spacious cargo bay and the ability to operate from unpaved airstrips. Consequently, in August 2009, both countries agreed to resume development of the An-70. Ukraine continued to pursue flight testing of the sole prototype while making upgrades to the aircraft's avionics, sensors and propulsion system. It was reported that the Ukrainian Air Force would take delivery of its first two An-70s in 2011 and 2012; Volga-Dnepr Airlines had also signed an MoU with Antonov for five commercial-standard An-70Ts. A requirement for 60 An-70s was included in Russia's 2011–2020 national armament programme when it was issued in December 2010. In late July 2010, Antonov suspended the flight test programme to update the aircraft. After an extensive series of modifications, including revised avionics (which reduced the flight crew from five to four) and changes to the aircraft's propellers to improve reliability and decrease noise, the second prototype An-70 flew again on 27 September 2012 and took part in the Aviasvit XXI airshow in Kyiv. During the same year, Russian and Ukrainian authorities agreed on the basic workshare of the production programme. Antonov in Kyiv would now produce the wings, tail surfaces and engine nacelles. The KAPO factory in Kazan, Russia, would be responsible for the manufacture of the fuselage, the final assembly of the aircraft, and flight testing. Other major components would come from Novosibirsk, Ulyanovsk and Voronezh; construction of the fuselage of the first production aircraft was reportedly complete in December 2012. The test programme would last from September 2012 until April 2014, when the aircraft passed state acceptance trials. During that time, the An-70 conducted approximately 120 flights totalling 220 hours, with much of the certification effort carried out by Ukrainian specialists and officials. This is because, despite the aircraft's inclusion in Russia's state rearmament programme, Russia had withdrawn from the project in November 2012 reportedly due to slow progress, a fact that was disclosed only in April 2013. According to a report, the withdrawal of Russia from the project was, apart from a response to the Ukrainian government's EU choices, the result of political manoeuvring by Russian government officials with links to Ilyushin to pressure the government to purchase the Il-476, a re-winged variant of the Il-76. In total, the An-70 had conducted some 735 flights and had accumulated 930 hours during state tests. As a result of the Crimean
