Environmental Tectonics Corporation Announces Receipt of Contract From United States Navy Valued at $19 Million

Environmental Tectonics Corporation (Amex: ETC) ("ETC" or the "Company") announced today that it has been awarded a contract by the United States Navy for a Disorientation Research Device. The contract, valued at over $19 million, was awarded to ETC following a competitive bid process. The device, ETC's GYROLAB GL-6000, will be manufactured at ETC's main manufacturing plant in Southampton, PA.

The contract calls for delivery by July 2011. It will be installed at the 711th Human Performance Wing at Wright Patterson AFB, OH. The GL-6000 will support research activities conducted by the Naval Aerospace Medical Research Laboratory (NAMRL).

ETC's GYROLAB GL-6000 will provide the most advanced technology for research by featuring sustained-G capability and six distinct degrees of freedom (motions). The GL-6000 is capable of generating sustained G forces of up to 3Gs as well as motion in pitch, roll, yaw, heave, sway (side to side) and surge (fore - aft). The GL-6000 supports clinical research into high performance aircraft human factors issues. Additionally, the GL-6000 can support operational research including Head Up Displays, flight control ergonomics and instrument displays.

William F. Mitchell, President and Chairman of ETC, stated, "ETC is proud to be awarded the U.S. Navy contract for the NAMRL Disorientation Research Device. We look forward to providing this advanced technology device to support research activities to solve the human factors issues encountered by aircrew flying today's and tomorrow's high performance aircraft. The U.S. Navy is a long time and valued customer of ETC."

An event attended by the news media, numerous ETC suppliers and subcontractors, and several dignitaries was held at ETC's main manufacturing facility to announce the award of the contract that will generate jobs for the community and improve the health and safety of thousands using the GL-6000, next generation in motion-based technology.
