The Soumar ( Persian: سومار) is an Iranian long range cruise missile. The missile was named in the honour of a city called Soumar whose inhabitants were all killed when Saddam's regime attacked the city with chemical weapons.
On September 9, 2012, Iranian media quoted Iran's deputy defense minister that a medium range cruise missile called Meshkat will be revealed soon. He mentioned that the missile can be fired from ground, air and sea and will have a range of 2000 km. However the unveiling did not happen until 2015.
On 2015 a long range cruise missile was revealed under the name "Soumar". The design closely resembles the Kh-55 that Iran acquired from Ukraine in 2001. Because of the similarities media guess a range between 2000 and 3000 km for it.
