The United States has repeatedly voiced concern that such launches could boost Iran's ballistic missile technology, extending to the potential delivery of nuclear warheads.

But Iran insists it is not seeking nuclear weapons and that its satellite and rocket launches are for civil or defensive purposes only.

State television reported the "successful suborbital launch of the satellite launcher named Ghaem-100".

"The flight test of this launcher using the Rafe solid-fuel vehicle has been successfully completed," it said.

The Ghaem-100 rocket was manufactured by the aerospace organisation of the Islamic Revolutionary Guard Corps and it is the country's first three-stage solid-fuel satellite launcher, the channel added.

Ghaem-100 "is capable of placing satellites weighing 80 kilograms (176 pounds) in an orbit 500 kilometres (just over 300 miles) from the surface of the earth," it said.

Iran successfully put its first military satellite into orbit in April 2020, drawing a sharp rebuke from Washington.

In August this year, another Iranian satellite, named Khayyam, was launched by Russia on a Soyuz-2.1b rocket from Baikonur Cosmodrome in Kazakhstan.

Iran's space agency said the device was constructed by Russia under Iran's supervision.

The US alleged at the time that the Khayyam would enable "significant spying capabilities" and that a deepening Russia-Iran alliance amounted to a "profound threat" to the world.

Iran's space agency rejected those allegations, countering that the purpose of Khayyam was to "monitor the country's borders", and help with the management of natural resources and agriculture.
