"Line [Insert item name and program description] has not completed U.S. Government testing and is not yet in full production. There is a risk that if problems arise in testing, this system may never achieve its desired operational effects. Further, even if testing is successful, the U.S. Government may decide not to acquire this system. If there is no U.S. Government acquisition, the procurement cost of the item will likely increase, there may be delays to the scheduled delivery of this system, and there could be future interoperability problems with U.S. forces."
