“Other Transactions Agreement (OTA)” is the term commonly used to refer to the 10 USC 2371b authority to enter into transactions other than contracts, grants or cooperative agreements. The Department of Defense (DoD) currently has temporary authority to award relevant to weapons or weapons systems proposed to be acquired or developed by the DoD. OTA’s for prototype initiatives are acquisition instruments that generally, are not subject to the federal laws and regulations governing procurement (FAR based) contracts. As such, they are not required to comply with the Federal Acquisition Regulation (FAR), its supplements (i.e. DFARS) or laws that are limited in applicability to procurement contracts.
