Challenger C-168 escorted three F-16 Fighting Falcons last summer to test the possibility of operating the type in Greenland.
RDAF F-16 Fighting Falcons intercept a Challenger as part of their Quick Reaction Alert training.
The Challengers’ main system in the fight against oil pollution is the Terma 9000 SLAR radar fitted under the fuselage.
Apart from the SLAR radar, the Challenger can also be equipped with a Telephonies APS-143B(V)3 Ocean Eye surface radar as seen here on C-172.
The CL-604 Challenger is equipped with a FLIR Systems Star Safire II thermal imaging sensor housed in a retractable housing underneath the rear of the aircraft.
Challengers can drop flares, life rafts and small and medium size packages from the rear cargo door. The latter capability is often used over Greenland to deliver supplies in remote areas.
Challenger C-215 is 721 Squadron's latest addition, seen here in the hangar shortly before being officially added to the squadron’s fleet.
The small but comfortable cockpit of the CL-604 Challenger is occupied by the mission commander in the left seat, and the first officer in the right.
During a maritime patrol mission, the two system operators in the back of the aircraft use the SLAR and thermal imaging sensor to monitor the sea looking for ships dumping oil.
