Cubic data link transfers data from U-2, F-18 aircraft
during U.S. government laboratory and flight testing

SAN DIEGO, Calif. – Aug. 16, 2005 -- Cubic Corporation (AMEX: CUB) said today that its defense segment, Cubic Defense Applications, successfully completed a series of critical tests involving Cubic’s Navy Communications Data Link System (CDLS). Cubic’s system demonstrated its capability to transfer data from high-altitude reconnaissance and tactical aircraft during the tests, conducted in the California desert with support from the Space and Naval Warfare Systems Command (SPAWAR), China Lake Naval Air Station, Lockheed Martin Aeronautics Co., the Department of Defense Joint Interoperability Test Command (JITC) and L-3 Communications.

Cubic’s CDLS successfully transmitted and received data with U-2 and F-18 aircraft data links during the testing. CDLS is an extremely high-speed data link that transmits signal and imagery intelligence data between reconnaissance aircraft sensors and surface ship processing systems. The system is designed to transmit 15 different waveforms at top speed to tactical aircraft via a secure network, and to allow naval commanders to receive ISR data aboard vessels.

The tests involved live flight operations in addition to laboratory tests.

Cubic delivered the first of a total of 18 data link systems this summer to SPAWAR and PEO C4I and Space. The first system was installed aboard the USS Eisenhower in July 2005. Sea trials are planned later in the year.

Cubic Defense Applications, one of Cubic Corporation’s two major segments, is a world leader in realistic combat training systems, mission support services and defense electronics. The corporation's other major segment, Cubic Transportation Systems, designs and manufactures automatic fare collection systems for public mass transit authorities.
