The Jonga was a Nissan designed vehicle formerly used by the Indian Army. Jonga was an acronym for Jabalpur Ordnance aNd Guncarriage Assembly,[3] manufactured by the Vehicle Factory Jabalpur.[1] They were produced for the Indian Army under an exclusive license granted by Nissan in 1965.[2][4][5]
The vehicle entered service in 1969 and production ceased in 1999. It served as one of the Indian Army's jeeps until it was phased out[6] and replaced mostly by the Mahindra MM540 jeep.[7]
History
The Indian Army showed an interest at the Nissan Patrol P60 and the Nissan 4W73 in the 1960s.[7] A decision was made to prioritize the eventual production of the jeeps in the aftermath of the Sino-Indian War.[8] The factory manufacturing the Jonga was commissioned for a cost of Rs. 32.06 crores by November 1965.[8] The costs were revised again twice; firstly, on December 1970 for Rs. 41.53 crores and again in January 1973 for Rs. 46.84 crores.[8]
The first Jongas made by VFJ were produced in 1969 for military use.[7] A civilian variant of the Jonga was later made in 1996.[2]
In 1999, the production of the Jonga stopped with 100 of them sold to civilians.[2]
In 2013, it was reported that 20,000 Jongas were still in service with the Indian military.[9] It also has reported sales of 2,000 Jongas to the state governments of Kerala, and Jammu and Kashmir.[9]
Design
As the Jonga's design was based on the Nissan P60 and 4W73, it made maintenance easy due to access to COTS parts.[7] In 1996, the VFJ introduced the new 3.0L Hino diesel engine for civilian versions,[2][10] which was sourced with assistance from Ashok Leyland.[11] It was known for its high ground clearance at 222 mm, its power at 3,800 rpm and peak torque at 1,800 rpm.[12]
The Jonga was originally made for 6 people before changes were made to allow seating capacity for up to 8 people.[9]
In 2014, it was reported that the Advanced Material and Process Research Centre (AMPRI) was working on an aluminum-based composite material, which was used to develop a brake drum from a combination of metal, ceramic and aluminum, and for other automobile components; this was produced in partnership with the Vehicle Research and Development Establishment (VRDE).[13] According to AMPRI, the item was tested by VFJ on a Jonga, which reported an increase in braking efficiency.[13]
Variants
The Jonga was known to be used as a general purpose vehicle, ambulance, gun carrier for recoilless rifles, recon and patrol vehicle.[2][12]
Criticism
There were reports that the Jonga's wheel bearings were prone to falling off according to a Border Roads Organisation report.[14] VFJ teams sent to inspect the damaged vehicles concluded that maintenance teams had not complied with the necessary procedures in conducting repairs and maintenance.[14]
