The CASA/IPTN CN-235 is a medium-range twin-turbo-prop aircraft developed jointly between CASA in Spain and IPTN in Indonesia as a regional airliner and military transport. Amongst its military roles are maritime patrol, surveillance and troop transport. The largest user is Turkey which has a total of 61 aircraft.

[edit] Design and development

The project was a joint venture between CASA and Indonesian manufacturer IPTN, which formed Airtech company to manage the programme. Responsibility for design and production was shared at 50% between the two companies. The partnership applied only to the Series 10 and Series 100/110, with later versions being developed independently.

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

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]^{[verification needed]}

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