A mic of Alenia's original G.222 and the avionics and engineering genius of the C-130J Hercules, the tactical airlifter C-27J Spartan is used for important missions. Possessing an exceptional level of maneuverability and famed for it's STOL takeoff and landings, this light cargo aircraft is a key part of the Air Force's mission.
The aircraft has commonality with the C-130J platform, with parts based upon it's avionics systems, propellers, engines, cargo management.
The C-27J is used for tricky cargo operations to short or unprepared airfields, tactical airborne operations and training, and as a 'last mile' platform providing support to soldiers in the field supporting, and taking the weight off, the Army and Navy's helicopter platforms. It can also be called upon for highly difficult search and rescue operations.
One of the C-27J's key technical differentiators is its ability to land on short runways (STOL, Short Takeoff and Landings) and on unpaved runways — essential characteristics for performing successful missions across vast and rough terrain in sometimes harsh weather conditions.
The C-27J can land on almost any surface — snow, sand, and soft soil below CBR 4 (California Bearing Ratio is one of the most widely used methods for measuring load-bearing structure of unprepared airstrips and the soil underneath it). Additionally, it is capable of taking off from and landing on unprepared airstrips less than 500 meters long-a significantly shorter distance than other competitors in its class. Moreover, the aircraft has the best ground manoeuvrability compared with other military transport aircraft, a quality that enables the C-27J to access to a larger number of airfields and airstrips around the world. The minimum strip width for ground inversion is 12.1 m.
There are several unique system features that enable the C-27J's outstanding STOL capability. First, the aircraft is equipped with landing gear and a brake system that are optimized for unprepared airstrips. Secondly, the aerodynamic design dimensions of the aircraft and advanced on-board avionics enable crews to optimize the flight profile in approach and in takeoff.
The C-27J has a climb rate comparable to a 4 engine aircraft (C-130J) and its time to climb up to 10,000 ft is just 6 min.
In approach the aircraft has the best steep descent capabilities compared with other military transport aircraft (4,000 ft/min), Its 14 cockpit windows allow better visibility for the pilots.
Additionally, the absence of specific design limitations as well as the aircraft's powerful engines, enable it to perform steep takeoffs and landings. Essentially, the C-27J can begin rotating/climbing immediately without any restrictions or fear of touching the tail. At takeoff, other aircraft in the class can start their rotation/climb only after flying at a level height, a few meters off the ground, which increases the necessary airfield length.
The C-27J’s structural strength, power and system redundancy provide a high-level of safety in very demanding operational scenarios, and an unbeatable mission accomplishment rate.
The aircraft is equipped with a double hydraulic circuit, 3 generators, 3 alternators, 3 Transformer Rectifier Units, 3 engine restart options, fuel jettison capability, and a 3-spar wing and vertical tail structure, making it the safest and most reliable platform in its class. The on-board Auxiliary Power Unit (APU) supplies both electrical and pneumatic power, and allows the C-27J to start easily in cold temperatures and operate autonomously from austere locations without external ground support.
The aircraft is fitted with a continuous jack extension system that allows aircraft levelling or “kneeling” for easy cargo transfer, and its fully reinforced floor removes weight limitations found on other platforms.
The C-27J possesses cutting edge avionics, with full detection sensors and countermeasures from missile fire, as well as a full bevy of communications equipment.
