The two planes were the fifth and sixth aircarft delivered to Iran to be used for domestic short-distance flights.
After the implementation of Iran nuclear deal also known as the Joint Comprehensive Plan of Action (JCPOA), Iran's national flag-carrier Iran Air signed contract with French Airbus, American Boeing and Franco-Italian ATR, to renew its air fleet buying 200 aircraft.
Iran has so far received three Airbus passenger planes and six ATR72 aircraft.
The ATR 72 is a twin-engine turboprop, short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR (Aerei da Trasporto Regionale or Avions de transport régional), a joint venture formed by French aerospace company Aérospatiale (now Airbus) and Italian aviation conglomerate Aeritalia.
The ATR plane manufacturer has signed a contract with Iran Air to provide it with 20 planes.
This is a third plane manufacturer after Airbus and Boeing had successfully signed lucrative deals with Iran.
Efforts to sign a deal with Brazilian manufacturer Embraer had been uninspiring and plans were abandoned in favor of Airbus and Boeing.
