| Source measurement | Once AIMP was completed the CP-140 was designated as CP-140M.[source]Lockheed CP-140 Aurora · Design and development / Aurora Incremental Modernization Project; only the objects and conditions stated in this passage Several options had been suggested for a CP-140M replacement. These included the Boeing P-8 Poseidon and the Raytheon Sentinel , based on the Bombardier Global Express -6500, as well as late entrant PAL Aerospace Global Express 6500-based P-6.[source]Lockheed CP-140 Aurora · Operational history / Replacement; only the objects and conditions stated in this passage The RCAF had planned to downsize the fleet from eighteen to fourteen aircraft, with three already being withdrawn and a fourth test aircraft to be retired in the near future. The retirement of the CP-140 was originally expected around 2030, and could have resulted in a capability gap as the RCAF did not anticipate replacements to be delivered until 2032 to 2038. The RCAF's Weapon System Manager (WSM) had prepared plans to have the CP-140M operational until 2035 to 2040.[source]Lockheed CP-140 Aurora · Operational history / Replacement; only the objects and conditions stated in this passage Royal Canadian Air Force 404 Long Range Patrol and Training Squadron , CFB Greenwood , Nova Scotia 4 × CP-140M Aurora 405 Long Range Patrol Squadron , CFB Greenwood , Nova Scotia 11 × CP-140M Aurora and 1 × CP-140 Aurora to be retained as a test aircraft until retirement in the near future. 415 Long Range Patrol Force Development Squadron , CFB Greenwood , Nova Scotia 407 Long Range Patrol Squadron , CFB Comox , British Columbia 3 × CP-140M Aurora[source]Lockheed CP-140 Aurora · Operators; only the objects and conditions stated in this passage Length: 116 ft 10 in (35.61 m)[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Wingspan: 99 ft 8 in (30.38 m)[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Height: 33 ft 8.5 in (10.274 m)[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Wing area: 1,300 sq ft (120 m 2 )[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Gross weight: 61,362 lb (27,833 kg)[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Powerplant: 4 × Allison T56-A-14-LFE turboprop engines, 4,909 hp (3,661 kW) each[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Propellers: 4-bladed Hamilton Standard 54H60, 13 ft 6 in (4.11 m) diameter constant-speed fully-feathering reversible-pitch propellers[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Maximum speed: 375 kn (432 mph, 694 km/h) below cruise ceiling[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Maximum transit speed: 395 kn (455 mph; 732 km/h) at optimum altitude[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Range: 5,000 nmi (5,800 mi, 9,300 km)[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Endurance: 8 hours 12 minutes on station at 1,000 nmi (1,151 mi; 1,852 km) radius[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Service ceiling: 35,100 ft (10,700 m)[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage FAR balanced field length: 7,900 ft (2,408 m)[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Take-off distance to 50 ft (15 m): 6,000 ft (1,829 m)[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Landing distance from 50 ft (15 m): 3,200 ft (975 m) at 114,000 lb (51,710 kg) landing weight[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage Hardpoints: 8 in weapons bay; 10 under-wing from 611 to 2,450 lb (277 to 1,111 kg) capacity with a capacity of 4,800 lb (2,177 kg) total in weapons bay, with provisions to carry combinations of: Other: signal chargers, smoke markers , illumination flares[source]Lockheed CP-140 Aurora · Specifications (CP-140); only the objects and conditions stated in this passage | — |
