Design and development

The project was a joint venture between CASA and Indonesian manufacturer IPTN, which formed Airtech 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 and 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.

The CN-235 was selected by the United States Coast Guard for its Medium Range Surveillance Maritime Patrol Aircraft (MRSMPA) program as the HC-144A .[1] The first HC-144A was delivered by EADS CASA to Lockheed Martin for installation of the mission package in December 2006.[2] The HC- 144A Ocean Sentry achieved Initial Operational Capability (IOC) on April 2, 2009. Eight aircraft were delivered as of July 1, 2009.

In August 2006, three CASA CN-235-10 aircraft remain in airline service, in Africa, with Safair (two) and Tiko Air (one).[3] Asian Spirit operates a sole CN-235-220 in the Philippines, correct as of June/July 2007.

The Irish Air Corps operates two CASA aircraft in the maritime patrol capacity.

There are at least two CN-235s operating with the United States Air Force for an undisclosed role with the 427th Special Operations Squadron, at the former Pope AFB, NC.[4]

In early July, The Mexican Navy announced they will order six CASA CN-235 from Spain.[5]
