The Nahang (Persian: نهنگ, lit.'Whale') is an Iranian-made class of midget submarine designed for shallow water operations. Only one prototype of this class is known to be completed, although its characteristics have remained unclear.

History

[edit]

Iran had shown interest in midget submarines in the 1980s.[1] 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.[1] Iran reportedly purchased a second midget of another design from North Korea, delivered in 1988.[1] It is alleged that by 1993, nine midget submarines –able to displace 76 tons surfaced and 90 tons submerged, with a top speed between 8 knots (15 km/h; 9.2 mph) and 12 knots (22 km/h; 14 mph)– were imported from North Korea.[1]

Existence of Nahang was first known in April 2006.[2] On 6 March 2006, Iranian state television announced that Nahang 1 has been commissioned into the Southern Fleet.[3] Later that year in late August, she participated in the third phase of Zarbat-e Zolfaghar wargame.[4]

Two other submarines in the class were allegedly planned, but building further units is considered unlikely.[2]

In April 2017, Bellingcat reported that for the first time in years, satellite imagery suggests Nahang had been deployed for a mission.[5]

Description

[edit]

There is not much confidently known about characteristics of the class.[2] According to Jane's Fighting Ships, the class displaces 100 tonnes (98 long tons) when at the surface and 115 tonnes (113 long tons) while submerged.[2] Alternate estimates for surfaced and submerged displacement are 110 tonnes (110 long tons) and 127 tonnes (125 long tons) respectively[6] while the number given goes as high as 500 tonnes (490 long tons).[7]

Jane's mentions the approximate dimensions as 25 m (82 ft) for length, with a beam of 3 m (9.8 ft) and a draft of 2.5 m (8 ft 2 in).[2] 8 knots (15 km/h; 9.2 mph)[6] and 13 knots (24 km/h; 15 mph)[8] are top speeds reported for the submarine. Nahang is reportedly unarmed and not fitted with torpedoes,[2][9] however there are contradicting reports suggesting it has a pair of 533mm torpedo tubes in drop collars and can carry and lay four MDM-6 or EM-52 naval mines.[6] Nahang may be utilized as a mothership for swimmer delivery vehicles[2] and a platform for special operations.[9]

The submarine has no sonar on the report of Jane's,[2] but another account suggests that she is equipped with active/passive sonar on her bow.[6] The machinery installed for propulsion is unknown.[2] Other apparatus reportedly installed include a mast with electronic warfare support capabilities (similar to Russian-made 'Stop Light' type) and surface search and navigation radar.[6]
