Pressurized cargo cabin has temperature regulator and is equipped with in-floor cargo handling system, which makes An-70 a self-sufficient aircraft that has no need for ground handling equipment.

Program is financed by both Russian and Ukrajnian governments (165 and 65 aircraft planned, correspondingly). Strong competitor to European heavy transport 'Euroflug' (Airbus FLA A-400M Future Large Aircraft). In February 1999 tender for new military cargo plane entered its final stage.

Despite the An-70 was selected by Russian Air Force as the main tactical transport, crash of the only built prototype 11 February 1995 (mid-air collision) and delays with construction and tests of the second one (not earlier than 2000) can lead to lose in favor of A.N.Tupolev Tu-330 (was expected to fly in 2000).
