AI Contract Overview
The Office of Naval Research is soliciting proposals for the Ocean Explorer (OEX) Large Underwater Vehicle Demonstrator, under solicitation number N0001425SBC04. The initiative aims to rapidly design, build, and test an ultra-large autonomous undersea vehicle capable of conducting extended missions across oceanic distances while accommodating a significant modular payload. The contract emphasizes innovation both in large-scale undersea vehicle technology and in the accelerated prototyping process. The solicitation process involves an initial call for white papers followed by submission of a fully costed proposal addressing the Preliminary Design phase (Phase 1A), with an option for a Detailed Design phase (Phase 1B). The goal during Preliminary Design is to validate the technical feasibility of the vehicle, including its payload module, and to outline the operational and maintenance framework necessary to support an operational fleet or “squadron” of OEX vehicles. Posted on July 24, 2025, with amendments on both June 24, 2025, and July 24, 2025, potential applicants are encouraged to consult the updated attachments. The response deadline is October 31, 2025. The solicitation targets NAICS code 541715 (Research and Development in the Physical, Engineering, and Life Sciences), and is open to qualified performers capable of meeting the technical and timeline demands of the program. The point of contact for interested parties is Leila Hemenway at the Office of Naval Research in Arlington, Virginia.

The Office of Naval Research (ONR) seeks potential performers who are interested in pursuing the rapid design, build, and testing of OEX, an ultra-large autonomous undersea vehicle capable of conducting extended ocean scale missions while carrying a large modular payload. Innovation is sought both in terms of ultra-large undersea vehicle technology and in rapid prototype design and fabrication. The BAA Call initially seeks white papers followed by a full costed proposal covering an OEX “Preliminary Design” phase (Phase 1A) with a “Detailed Design” option (Phase 1B). The purpose of the OEX Preliminary Design is to establish the technical feasibility of the vehicle (with a payload module) and to lay out the operational and maintenance infrastructure required to support a hypothetical OEX “squadron”.
