Iranian Defense Minister Brigadier General Ahmad Vahidi has inaugurated the production line of Iran's longest-range artillery ammunitions, Press TV reported.
Speaking at the inaugural ceremony of the mass production of Base bleed projectiles in the capital Tehran, General Vahidi said the new 130 millimeter advanced artillery shells will be the longest range artillery shells in arsenals of the Islamic Republic's army, Iran's Defense Ministry said on its website.
"These ammunitions use solid propellants and act like ballistic missile," the Iranian defense minister noted.
He also lauded Iranian experts at the arms production division of the country's defense industries for their efforts to modify the base bleed system in order to further enhance the range of the ammunitions from 27 to 42 kilometers.
The defense minister also said such achievements demonstrate that sanctions against Iran have been ineffective.
Base bleed is a system used on some artillery shells to increase their range, typically by about 30%.
Reshaping some artillery shells can significantly reduce the drag on the shells' nose when soaring at supersonic speeds.
Engineers have come up with certain aerodynamic re-patterning of suitable artillery shells to give them proper ballistics through boosting thrust and diminishing airflow pressure.
