The Department of the Navy's Naval Air Systems Command (NAVAIR) awarded a firm fixed price purchase order to DDC-I, Inc., a privately held software company that provides real-time operating systems and software development tools for safety-critical embedded applications in the aviation and defense sectors. The $159,184 contract is for annual software support and license renewals to maintain and technically support DDC-I's aviation software utilized in NAVAIR aircraft or weapons programs. This is a sole-source award as DDC-I's software is uniquely compatible with existing code. The contract does not have a set-aside designation. DDC-I has also served as a subcontractor providing computer software and subscriptions to prime contractors Raytheon and Science Applications International Corporation for defense systems engineering and development programs.
