Iran's Revolutionary Guards Corps, or IRGC, on Tuesday unveiled its newest aerial surveillance drone during large-scale military exercises in the western part of the country.

Iranian media reports the drone, named "Hamasseh" or "Epic" in English, conducted its first ever surveillance flights during the exercise in Sistan and Baluchestan Province in western Iran. The drone flew as part of a three-plane formation and carried out several high-altitude reconnaissance flights, Iranian news outlet Press TV.

The Iranian military's smaller, tactical Mojahr-1 and Ababil-5 drones as well as the high-altitude Shahed-129 surveillance drone flew alongside the Hamasseh during the exercises, IRGC's Ground Forces Brigadier General Mohammad Pakpour said.

Aside from long-range surveillance operations, the drone is also reportedly designed to carry out airstrikes as part of its anticipated multimission package.

The drone will continue to see action during the exercise in Kerman, South Khorasan and Homozgan, Pakpour added. The drills are expected to wrap up on April 14th.

On Monday, Tehran announced the first tranche of Russian-built S-300 long-range surface-to-air missile systems are en route to the Iranian military. The weapons transited to Iran via the Caspian Sea arriving this week, the country's Foreign Ministry spokesman Jaberi Ansari said Monday.
