Technical Communications Corporation (OTC BB: TCCO.OB), an international communication security and encryption technology company, has received orders valued at approximately $9.7 million for a major expansion of its DSP 9000 military radio encryptors to be deployed in Afghanistan. These orders include shipments of DSP 9000 radio encryptors for the local forces in Afghanistan. These new orders were received from Datron World Communications, Inc., a global supplier of HF/VHF tactical communications equipment. Accelerated deliveries have been requested for this order which is planned to be substantially completed in fiscal 2010 and is expected to raise TCC's sales for 2010 to record levels of approximately $20 million. This order results from the U.S. effort to equip the Afghan National forces as part of President Obama’s troop build-up in Afghanistan. This immediate need generates significant growth for TCC, and although we expect to continue to supply the Afghan forces in the future we do not expect individual orders of this magnitude.

During the past year, TCC has seen an increase in shipments to the region, which is driven by the need for secure (encrypted) tactical radio communications between NATO and local security forces. TCC believes this new deployment will significantly increase the ability of the Afghan, NATO and US forces to communicate securely over HF, VHF and UHF radios.

The TCC DSP 9000 family of radio encryptors for HF, VHF, and UHF radios are rugged, field grade products with a proven track record of over 15 years of solid, in-use performance with many government agencies and armed forces around the world. The DSP 9000 comes in several models, configurable for airborne, naval, manpack and land vehicle and police applications.
