Iran Unveils Short-range Missile Upgrade, Plans to Build Self-made Fighter Jet

WATCH: Ahmadinejad announces new version of Fateh-110; Islamic Republic's defense minister says Tehran working on domestically made warplanes, drones, and submarines.

Iran's official news agency says the country has upgraded a short-range surface-to-surface ballistic missile just weeks after it was test-fired.

Tuesday's report by IRNA says President Mahmoud Ahmadinejad unveiled the new version of Fateh-110, or Conqueror.

IRNA says the new version has a quicker launch capability and longer life but gave no other details. It has been in service in Iran over the past decade.

Iran claimed earlier in August that it successfully test-fired the missile, which has an improved accuracy to strike land and naval targets within a 300 kilometer (185 miles) range.

Iran has been pushing to upgrade its missiles, which already can target Israel and other parts of the region. The pursuit is part of Iran's efforts since 1992 for a self-sufficient military program.

Also on Tuesday, Iran's Defense Minister Ahmad Vahidi told the country's semi-official news agency Mehr that Islamic Republic will produce domcesticaly-made fighter jets by the end of the current Iranian year, ending March 2013.

God willing the Defense Ministrys fighter jets will be operational by the end of the year, Vahidi said in a ceremony marking the Defense Industry Day.

The Iranian defense minister also indicated that Tehran was mulling the manufacture of self-made drones, as well as of submarines.
