The FAA is soliciting bids from companies interested in competing for NextGen (Next Generation Air Transportation System) support contracts with an approximate combined value of $7 billion, the largest award in the agency’s history. NextGen is the FAA's plan to modernize the National Airspace System through 2025. Under the umbrella awards, called System Engineering 2020 (SE2020), the FAA will award as many as five contracts for R&D and systems engineering work. The SE2020 contracts will be awarded to teams of companies, up to three of which will perform R&D work and two of which will perform systems engineering work. This work will complement and enhance major NextGen initiatives already under way, such as Automatic Dependent Surveillance–Broadcast, System Wide Information Management, and Data Communications. Contract teams will focus on a series of operational capabilities, including Trajectory Based Operations, Collaborative Air Traffic Management, and Reduced Weather Impact. Five-year contracts will be awarded next summer, with subsequent three- and two-year options.
