Canadair Challenger 600

The Canadair Challenger 600 series is a family of business jets. It was first produced by Canadair as an independent company and then produced from 1986 by Canadair as a division of Bombardier Aerospace.
==Variants==
===CL-600===
*CL-600: Original production version, powered by Avco Lycoming ALF 502L turbofans of 7500 lbf (33.6 kN) thrust each. Built from 1978 to 1982 (81 built).
*CL-600S: Three CL-600s retrofitted with the winglets introduced on the CL-601-1A.
*Canadair CC-144: Twelve aircraft purchased by the Royal Canadian Air Force, including the CE-144 and CX-144
*Canadair CE-144: Three Electronic warfare / EW trainers converted to/from basic CC-144.
*Canadair CX-144: Second prototype, a CL-600-1A11, c/n 1002, allocated to the RCAF after finishing test programme. Used at the Aerospace Engineering and Test Establishment (AETE), CFB Cold Lake until retirement in 1993, now preserved at the CFB Winnipeg. Designated CC-144 in service.
===CL-601===
*CL-601-1A: A refined version including winglets to decrease drag and more powerful General Electric CF34-1A (66 built, including six Canadian Forces CC-144B).
*CL-601-1A/ER: 601-1A retrofitted with an additional fuel tank in the tail.
*CL-601-3A: GE CF34-3A engines with a higher flat rating and a glass cockpit. This was the first version marketed by Bombardier.
*CL-601-3A/ER: 601-3A with an additional, optional fuel tank in the tail.
*CL-601-3R: The tail tank was made standard, CF34-3A1 Engines were introduced.
*CL-601s: Version powered by GE CF34-3A2 engines.
===CL-604===
*CL-604: A major upgrade of the 601 design, incorporating more advanced GE CF34-3B engines; increased fuel capacity, including saddle tanks in the rear of the aircraft; new undercarriage for a higher takeoff and landing weight; structural improvements to wings and tail; and a new Rockwell Collins ProLine 4 avionics system.
*CL-604 MMA: (Multi-Mission Aircraft), militarized version, developed by Field Aviation, in Danish service. The aircraft are employed on maritime patrol and search and rescue missions. They are capable of landing on the short, rough, gravel airstrips common in the Arctic.
*C-143: A single Challenger 604 aircraft was acquired by the United States Coast Guard in December 2005 as its new Medium Range Command and Control Aircraft (MRC2A).
===CL-605===
*CL-605: Introduced in early 2006 as an avionics and structural upgrade of the 604 design. Structural improvements include larger cabin windows. Cockpit instrumentation updated with the Collins Proline 21 avionics and "electronic flight bag" capability. It can be visually identified by a new, rounded tailcone.
*CL-605 MSA: A maritime patrol aircraft design under development by Bombardier and Boeing. Boeing has proposed a repackaging of some of the Boeing P-8 Poseidon sensors but not weapons into a less expensive airframe, the Bombardier Challenger 605 business jet. This aircraft is named Maritime Surveillance Aircraft (MSA) and has been depicted with the AN/APY-10 radar, an electro-optical sensor in a retractable turret, and a magnetic anomaly detector. On February 28, 2014, a MSA demonstrator which is a modified CL-604 made its first flight, but the final aircraft will use the CL-605 airframe. The demonstrator currently has the external shapes for the sensors and communications systems which will be added later. The final MSA is expected to cost $55 million to $60 million per aircraft.
===CL-650===
*CL-650: The CL-650 is a major upgrade of the CL-605. It includes a completely redesigned interior cabin, the new "Vision" flight Deck which is a Rockwell Collins Proline 21 Enhanced, and a 5% increase of takeoff thrust.
