PRESS RELEASE : SEPTEMBER 6, 2006
DUCOMMUN INCORPORATED ANNOUNCES $2.6 MILLION CONTRACT AWARD FROM NASA MARSHALL SPACE FLIGHT CENTER FOR CREW EXPLORATION VEHICLE AND CREW LAUNCH VEHICLE SUPPORT

LOS ANGELES, California (September 6, 2006) -- Ducommun Incorporated (NYSE:DCO) today announced that Miltec, a wholly owned subsidiary of Ducommun Technologies, Inc., has been awarded a $2.6 million contract to provide hardware-in-the-loop simulation support for National Aeronautics and Space Administration’s (NASA) Marshall Space Flight Center (MSFC) avionics laboratories in Huntsville, Alabama. Under the terms of the contract, the Miltec team will participate with NASA personnel in the enhancement of MSFC hardware-in-the-loop simulation laboratories in preparation for testing the next generation of launch vehicles that will return humans to the moon and then to Mars and other destinations. MSFC hardware-in-the-loop simulation capabilities will be enhanced to support Crew Exploration Vehicle (CEV) and Crew Launch Vehicle (CLV) testing activities beginning in 2007. Additionally, MSFC hardware-in-the-loop laboratories will support a common simulation infrastructure providing a standard simulation environment across facilities; thus, increasing the utilization of personnel, and reducing training, testing and maintenance costs.

Joseph C. Berenato, chairman, president and chief executive officer of Ducommun, stated, “We are excited to support NASA’s vision for space exploration. The Marshall Space Flight Center simulation labs have unique capabilities where mission components are tested in a wide variety of environments that include pre-launch operations, launch, orbital maneuvers, rendezvous, docking, berthing and landing. Ducommun has been a supplier to NASA for many years, providing hardware for the Space Shuttle’s External Fuel Tank. We will continue to seek other opportunities to support NASA in its space exploration endeavors.”

Ducommun Technologies is a leading technology company with design, development, manufacturing, integration, and test capabilities in the areas of missiles, space, sensor, simulations, complex electronic/mechanical assemblies, illuminated cockpit displays, RF systems and space qualified motion control devices.

Founded in 1849, Ducommun Incorporated provides engineering and manufacturing services to the aerospace and defense industry.
