The UNLOCK AUKUS Act proposes to amend the Arms Export Control Act to facilitate defense cooperation within the AUKUS partnership . This legislation specifically modifies an existing limitation concerning the export and transfer of defense articles and services to AUKUS partners. By inserting an exclusion for subclauses (I), (II), and (III) of subsection (j)(1)(C)(ii) into Section 38(l)(4)(B) of the Act, the bill aims to streamline the process for such transfers. This change is intended to remove specific regulatory hurdles, thereby enhancing the ability of the United States to share defense technology and capabilities with Australia and the United Kingdom. The overall goal is to strengthen the AUKUS security pact by easing restrictions on collaborative defense efforts.
