IAIO Qaher-313

The IAIO Qaher-313 (Persian: قاهر-۳۱۳; also Ghaher-313, Conqueror (Tamer)-313, Q-313, F-313) is an Iranian prototype aircraft. Originally intended to be a manned single-seat potential 5th generation aircraft and stealth fighter, the Qaher-313 was publicly announced on 1 February 2013. Independent experts have expressed significant doubts about the viability of the aircraft. In early 2023, Iranian media reported that the Qaher-313 was being modified from a manned fighter aircraft into an unmanned aerial vehicle.

According to Iranian government sources, the F-313 Qaher was designed and is indigenously produced in Iran by the Iran Aviation Industries Organization (IAIO), a division of the Ministry of Defense, and IRIAF. The project manager is Hassan Parvaneh.

The aircraft design is a canard configuration. It was initially described as a stealth fighter built with advanced materials, a very low radar signature and with low-altitude operations capability that could carry either two 2,000-pound (910 kg) bombs, multiple smaller smart guided missiles, or at least 6 PL-12 type air-to-air missiles; these claims were later debunked by numerous international experts. It features a downward wingtip device. Iran claims they have designed the aircraft using CATIA three-dimensional interactive design software and tested it using simulation software including Gambit numerical grid generation software, fluent flow analysis and simulation software, CFD models and that they have additionally tested the aerodynamics using small sized jet and propeller flying models.

A prototype version of the Qaher-313 was portrayed to have test-flown at some point before the presentation. According to the head of the design team, two sub-sized models have been created and tested. One of the models uses a propeller engine while the other uses a small micro jet engine. The models were shown in a video clip (along with descriptions by the head of the design team) the same day. According to Haaretz, the "blurry video published by the Iranians purporting to show the Qaher 313 in flight seems to show not a manned fighter jet but a small radio-operated drone" which agrees with what the designers said about the videos at the Qaher-313 introduction ceremony.^{[citation needed]}

On 10 February 2013, the Iranian Minister of Defense said the claims made by foreign media about the project are inaccurate and that the engine used by the design had been successfully tested. He also confirmed that the aircraft had not yet been flown, but that taxi and flight tests will occur in the near future.

On 5 March 2017, Iranian Defense Minister Brigadier General Hossein Dehghan stated that the Qaher-313 was ready for flight testing. It was described by the Fars News Agency as a "logistic aircraft for short distances" and a "light fighter jet used for military and training operations".

A subsequent third prototype, designated "08", introduced a number of changes over the models previously showcased, most notably an enlarged cockpit, dual jet exhausts, and a FLIR turret in the nose.

On February 10th, 2026, a satellite photo was released showing a possible prototype for the Qaher-313
