Announcement PDF ABN 32 009 344 058 4 Whipple Street, Balcatta WA 6021 Telephone: +61 8 9441 2311 Facsimile: +61 8 9441 2133 www.orbitalcorp.com.au ASX Code: OEC FOR IMMEDIATE RELEASE : 12 MAY, 2015 ScanEagle UAV to include Orbital fuel supply module      Orbital’s new innovative design for Insitu’s ScanEagle UAV propulsion system to include an integrated oil and fuel storage and supply system as part of the new UAV engine The integration of the new Orbital UAV engine and ancillaries with the oil and fuel storage and supply systems will enable Orbital to deliver a total propulsion system solution to Insitu for the ScanEagle UAV program The increased content to be provided by Orbital has the potential to significantly increase the revenue from the future ScanEagle production program Orbital’s innovative new design is expected to provide a significant competitive advantage for Insitu Insitu, a subsidiary of Boeing, have chosen Orbital as the preferred supplier for the ScanEagle UAV program and commercial negotiations are continuing for an initial production contract Orbital Corporation Limited (ASX: OEC) (“Orbital” or “the Company”) is pleased to announce the new generation ScanEagle Unmanned Aerial Vehicle (“UAV”) is expected to include an advanced fuel and oil supply module designed by Orbital as part of the propulsion system assembly included with the new Orbital UAV engine. The ScanEagle Unmanned Aircraft System is developed and built by Insitu Inc. (“Insitu”), a subsidiary of The Boeing Company (“Boeing”). Insitu have chosen Orbital as the preferred supplier of engines and propulsion systems for the new generation ScanEagle UAV. The propulsion system can also be retrofitted to existing ScanEagle UAVs. Orbital’s new UAV engine and propulsion system will include an advanced Orbital fuel and oil supply module. The module allows for a new state-of-the-art configuration that will allow all engine-related systems, including the fuel and oil supply systems, to be shipped from Orbital to Insitu in one assembled unit. The design improves reliability, reduces logistics expenses, and enhances easy access/swap out for in-field maintenance. The expansion of Orbital content in ScanEagle to include the fuel assembly as part of the engine design is a significant commercial outcome for Orbital as the Company progresses its UAV business from design validation into full production. The new Orbital UAV engine and propulsion system assembly combines the engine and ancillaries with the oil and fuel storage and supply systems into one unit, simplifying the aircraft assembly process and minimising the number of critical connections whilst also reducing size and weight. As part of this design, the integrity of all of the fuel and oil service connections can be checked prior to assembly of the aircraft, which is a significant improvement over competitor systems. Without assembly of the various modules as one unit, each of these tanks and connections would have to be individually mounted within the airframe and all plumbing connections would have to be made and tested where space and easy access is limited. Mr Terry Stinson, CEO and Managing Director of Orbital, stated “We are very pleased to be a key contributor to this product enhancement to ScanEagle. This is a win-win for Insitu and Orbital: Orbital is adding value by improving reliability and Insitu gains a new competitive advantage through a simpler aircraft assembly and easier access for maintenance/swap out of these systems. The new Orbital fuel and oil supply module enhances Orbital’s UAV engine business and future revenue potential. We are working with Insitu and Boeing to finalise the terms of a production contract for the ScanEagle program and then intend to move as rapidly as possible into fullscale production.” 1 CONTACTS Website: www.orbitalcorp.com.au Mr. Terry Stinson Chief Executive Officer Tel: +61 8 9441 2311 tstinson@orbitalcorp.com.au Mr. Ian Veitch Chief Financial Officer Tel: +61 8 9441 2311 iveitch@orbitalcorp.com.au About Orbital Orbital is an international developer of innovative technical solutions.
