TEHRAN, Iran — Iran has unveiled a new helicopter designed for offshore operations, medical evacuations and surveillance.

The official IRNA news agency said Tuesday that the four-bladed Saba-248 has two engines but is capable of operating with just one, and that it can fly in temperatures ranging from minus 13 to 131 degrees Fahrenheit.

Iran has been producing its own weapons and military equipment, including missiles, fighter jets and submarines, for more than two decades.
