The Israel Air Force has committed to buying at least three news; the first will be delivered in 2013. In parallel, extending the life span of the remaining is becoming critical due to the rapid ageing of these aircraft, due to the exhaustive flight profile they endure.
The US Air Force specified a 40,000 threshold Equivalent Baseline flight Hours () service life, beyond which CWB replacement becomes mandatory Ð an expensive endeavor performed by only a handful of qualified Maintenance, Repair and Overall ( ) centers around the world. Some operators decide to phase out their older Hercules, sell them in the surplus market or cannibalize them to maintain the remaining, younger fleet.
For most air forces, 40,000 hours are measured in decades. But some would meet this threshold much sooner than others. For air forces that operate their C-130s in combat conditions each flight hour is multiplied by thefactor, determined by the typical mission profile this flies. Therefore, those airplanes flying more demanding profiles, with the US Air Force Special Operations Command (AFSOC), US Marine Corps or the Israel Air Force, for example, will burn much faster than others, reaching their threshold earlier than the 40,000 goal.
Only a handful ofcenters have qualified to perform this service worldwide, in the US, Canada, UK, Israel and Singapore, in anticipation to more air forces reaching the ‘point of no return’. This extensive and costly process has already been performed on 50 aircraft at Warner Robins Air Logistics Center. Few air forces outside the US have also undertaken the process, among them five in Australia and New Zealand.
With EBH factor twice the US Air Force average, the Israel Air Force is reaching the CWB replacement much earlier than most other air forces. In its current multi-year plan the Israel MOD has allocated budget for the procurement of threes, setting aside additional budget for the sustainment and modernization of part of the remaining fleet. The modernization includes the life extension work (airframe, wiring and central wing box replacement) to be performed at and comprehensive avionic modernization provided by .
Ltd. announced it has been awarded a contract by the Israel Ministry of Defense (IMOD) to upgrade the Israeli Air Force’s (IAF) Hercules transport aircraft. The modernization project will extend the operational life of the aircraft and significantly improve its operational capability, particularly in precision flying, low-level night flight and operations in adverse weather. The modernization will contribute to improved flight safety and reduce operating costs, by introducing cutting-edge digital systems to replace obsolete analog systems that have become unreliable and costly to maintain after four decades of intensive service with the IAF.
According to Elbit Systems’ Aerospace Division Co-General Manager, Yoram Shmuely, the proposed upgrade utilizes systems, subsystems and applications being deployed on the most advanced platforms and military and civil upgrade programs in order to meet current operational needs and enable integration of future operational and technology capabilities.
Key elements of the upgrade are the integration of all-digital avionic architecture, providing the pilot and co-pilot the ability to fly ‘heads up’ or ‘head down’, in day or night, using EL-OP Head-Up Displays (HUD). The HUDs present flight data as well as images from thermal camera, enabling the pilots to safely fly ‘heads up’ at low altitude, in day, night and under adverse weather conditions. Another improvement is the introduction of terrain avoidance/terrain following system for the C-130, which is likely to be considered by the IAF once proven in flight demonstrations.AN/APN-241 weather/navigation radar replacing the current weather/navigation radar. The AN/APN-241 is the same model used on new C-130J. In addition to its basic functions it also supports terrain-following flight modes pursued by Elbit Systems and under a separate program. Other improvements include the introduction of a new autopilot, providing more reliable and improved automated functions, Engine Indicating and Crew Alerting System (EICAS) and smart panels for the pilots, navigator and flight engineer. Elbit Systems and Northrop Grumman are cooperating on the development of
Developed as a modular and integrated flight-deck avionics and mission equipment package (MEP) for transport aircraft, Elbit Systems’ C-Suite architecture integrates all avionics on board, including mission computer, head-up displays, enhanced vision system, flight management systems, weather and mapping radar, communications, EO payload, self protection systems, helmet mounted displays etc. Integrating this complex array into clearly defined mission situational pictures, relevant to each phase of the mission or task in hand. Delivered as an affordable solution, C-Suite MEP maintains essential flight information visible at all time, enabling the crew to operate the systems intuitively, using six ‘smart panel’ modules.
On January 15, 2014 Elbit Systems announced it received a follow-on order from the IMOD worth US$15 million. These upgrades are also complant with CNS/ATM (Communications Navigation and Surveillance/Air Traffic Management) requirements, enabling military transport planes to fly in international air traffic routes.
Life Extension Program
Airframe and Wing Earlier this year the IAF has allocated the first Hercules to go through the process at IAI. By the summer of 2012 the wing was removed and a new wing box delivered byinstalled. In parallel the IAF embarked on a long delayed upgrading and modernization of the remaining fleet of its C-130H. The RFP was distributed to several local companies, including IAI teamed with Astronautics as the avionic provider and Elbit Systems offering its own avionic systems, as part of the modernization. The CWB is expected to become part of this modernization process but not necessarily performed by the same vendor. The IAF provided the first aircraft to IAI to develop the process, and final decision will be made based on the outcome of the project.
IAIis offering the CWB replacement as part of a comprehensive upgrade, which also includes Programed Depot Maintenance (PDM), rewiring and avionic upgrade. The new wing box is cleared for 30,000 hours, extending the life expectancy of the upgraded aircraft for decades.
The avionic upgrade includes a modern glass cockpit with six multifunction panel displays, supporting flight operations and tactical displays, advanced navigation (EGI) and ECAS. According to IAI, a typical upgrading program including all phases would cost about a third, even quarter of the cost of a new C-130J, and provide for a transport plane that can remain in useful service for 30,000 hours. The upgraded C-130 are not offered as substitutes for the new C-130Js, but as a complimentary solution, sustaining a mixed fleet over a longer transition phase that would meet the air forces budget and operational requirements.
