The HESA Kowsar (Persian: کوثر, also spelt Kosar)[1] is an Iranian fighter jet based on the American Northrop F-5.[2][3] The aircraft is equipped with new fourth generation avionics in combination with an advanced fire control system.[4][1]

According to the Iranian media, this fighter jet has "advanced avionics" and multipurpose radar, and it was "100-percent indigenously made".[5] It also uses digital data networks, a glass cockpit, heads-up display (HUD), ballistic computers and smart mobile mapping systems. [6][7][8]

## Development

On 3 November 2018, there was a ceremony that inaugurated the launch of the Kowsar assembly line at the Iran Aircraft Manufacturing Industries Company (HESA) with at least seven being made.[9] President Hassan Rouhani was present as he inspected the Kowsar in the Defense Industry Day event celebration[10] in Isfahan.[11]

The HESA Kowsar has seven hardpoints with a total capacity of 3,200 kg (7,100 lb) of armaments and also has a 20 mm (0.79 in) cannon. It can carry up to four air-to-air Fatir missiles (a reverse engineering of Sidewinder missiles), or twelve 250 kg (550 lb) bombs or five 450 kg (990 lb) bombs or two 900 kg (2,000 lb) bombs. Kowsar has an Italian Grifo radar (a Chinese model or its domestic production has been used) with a range of 93 km (58 mi) that can engage two targets simultaneously.[12]

Western media have described the plane to be inefficient as a weapon, but having potential for training a new generation of Iranian fighter pilots.[13] There were reports of a crash by an Iranian-operated F-5 days after the Kowsar's existence was announced.[14]

### Export

## Design

The Kowsar, like the Saegheh and the Azarakhsh, was made based on the frame of the American F-5.[15]

### Variants

## Operational history

On 25 June 2020, the Iranian Ministry of Defence and Armed Forces Logistics announced that three new Kowsar aircraft had been delivered to the Islamic Republic of Iran Air Force, in a ceremony in Esfahan. The images published showed the aircraft painted in non-combat colours.[16]

## Reactions

### Official

Israel's defence minister Avigdor Liberman told press that it was a "natural reaction to an economic crisis", adding "[t]he Iranians are feeling very pressured by the continued US sanctions and in reaction they are coming out with these things, but we also shouldn’t dismiss it". Ofir Gendelman, spokesperson of the prime minister's office tweeted "The Iranian regime unveils the Kowsar plane and claims that it is ‘the first 100% locally-manufactured Iranian fighter jet'. It boasts about its offensive capabilities. But I immediately noticed that this is a very old American war plane (it was manufactured in the '50s). It is from the F-5 class of jets which has not been in use for decades".[17]

### Commentators

According to Douglas Barrie, military aerospace senior fellow at the IISS, the Iranians have possibly made upgrades and changes to the Kowsar while keeping the basic F-5 jet frame.[18] He also suggests that while Iran can reverse engineer the jet frame, the problem lies in sourcing engines and avionics.[19]
