Design and developmentThe project was a joint venture between CASA and Indonesian manufacturer IPTN, which formed the Airtec company to manage the programme. The partnership applied only to the Series 10 and Series 100/110, with later versions being developed independently. Over 230 of all versions of CN-235 are in service and have accumulated more than 500,000 flight hours.
Design began in January 1980 with first flight on 11 November 1983. Spanish and Indonesian certification was on 20 June 1986; the first flight of the production aircraft was on 19 August 1986 and FAA type approval was granted on 3 December 1986. The aircraft entered service on 1 March 1988
In 1995, CASA launched development of a stretched CN-235 as the C-295. In December 2002, the Columbian Navy ordered two CN-235 for patrol and anti-drug trafficking missions.
In April 2005, Venezuela ordered two CN-235 maritime surveillance aircraft plus 10 transport planes but the operation was halted due the United States refuse to allow US technology to be transferred.
In January 2006, Thailand placed an order with Dirgantara for ten aircraft, six for the Ministry of Defence and four for the Ministry of Agriculture.
In December 2007, Spain ordered two CN-235 maritime patrol aircraft for the Guardia Civil, for delivery 2008–2009.
One CN-235 MPA aircraft was delivered by Dirgantara to the Indonesian defence ministry in June 2008.
Irish Air Corps operates two CASA aircraft for maritime patrol duty.
There are at least two CN-235s flying with the United States Air Force for an undisclosed role with the 427th Special Operations Squadron, located at the former Pope AFB, North Carolina.[verification needed]
In early July 2008, The Mexican Navy announced that it will purchase six CASA CN-235s from Spain. In April 2010, Hervé Morin, French Minister of Defence, announced the order of eight CN-235-300s from Spain.
On 2011, PT Dirgantara Indonesia is still working on 4 CN-235-110 MPAs for South Korea Coast Guard with amount of $96 million
