History
Iran had shown interest in midget submarines in the 1980s.
According to the ''Conway's All The World's Fighting Ships'', Iran assembled a midget in
Bandar Abbas that was completed in 1987 in an unsuccessful attempt.
Iran reportedly purchased a second midget of another design from
North Korea

, delivered in 1988.
It is alleged that by 1993, nine midget submarines –able to displace 76 tons surfaced and 90 tons submerged, with a top speed between and – were imported from North Korea.
Existence of ''Nahang'' was first known in April 2006.
On 6 March 2006, Iranian state television announced that ''Nahang 1'' has been commissioned into the
Southern Fleet. Later that year in late August, she participated in the third phase of Zarbat-e Zolfaghar wargame.
Two other submarines in the class were allegedly planned, but building further units is considered unlikely.
In April 2017,
Bellingcat reported that for the first time in years, satellite imagery suggests ''Nahang'' had been deployed for a mission.
Description
There is not much confidently known about characteristics of the class.
According to ''
Jane's Fighting Ships'', the class displaces when at the surface and while submerged.
