TEHRAN: Iran has successfully tested a radar-evading aircraft, a commander said on Sunday, in the country's latest announcement of technological advances as it marks the anniversary of the 1979 Islamic revolution.

The semi-official Fars News Agency, citing senior air force official Aziz Nasirzadeh, said the prototype of a radar-evading aircraft named Swordfish had been test-flown.

"The prototype of this aircraft ... completed all radar evading characteristics considered by us," he said. "We are evaluating the data from the test flight and it will go into production after completing additional tests."

Iran is embroiled in a dispute with the West over its nuclear programme and often makes announcements of progress in its military capabilities, in an apparent attempt to show its readiness to respond to any military attack.

On Saturday, it officially started production of two new missiles, state media said, three days after it launched a rocket which can carry a satellite.

During the February 1-11 period, Iran marks the 31st anniversary of the Islamic revolution that toppled the U.S.-backed shah.
