### Project 0304 — Technology Maturation and Transition

Technology Maturation and Transition: Funds vetted and endorsed experimentation, demonstration and prototyping of technologies and capabilities based on projects curated from initiatives throughout the joint and USN innovation portfolio. Projects align with National Defense Strategy (NDS), Chief of Naval Operations and Fleet priorities and receive USN endorsement based on a rigorous vetting process and the closure of critical capability gaps. Projects are cross-domain and accelerate integration of high priority technologies to enable transition into Programs of Record and support warfighter needs.

### Project 0303 — Tactical Adv for the Next Generation (TANG)

Tactical Advancements for the Next Generation (TANG) projects solve mission-focused, human-centered challenges leveraging a divergent-convergent process (e.g., design thinking) via three-phased approach. TANG harnesses the expertise and perspective of the user, subject matter experts, stakeholders, and industry partners, to ideate and create new actionable concepts and transition prototypes and solutions that will impact the DoW. Phase I - Co-Discovering Opportunities: Engage stakeholders, end-users, and experts to uncover pain points and opportunities. Conduct domain research, interviews, and observations to build operational context. The output of Phase I includes a Phase I Primer (project introduction for stakeholders), Insights & Opportunities Document (prioritized problem framing and "How Might We" questions), and a Phase I Alignment Sprint (validates findings and aligns with sponsors on focus areas). Phase II - Co-Creating Concepts: Facilitate Design Workshops with multi-disciplinary participants (users, sponsors, SMEs) to co-create potential solutions. Conduct analogous research (drawing inspiration from other industries) to expand creative thinking. The output of Phase II includes a Concepts Deep Dive (refined concepts and a strategic vision for the future) and a Phase II Alignment Sprint (prioritizes concepts and sets direction for prototyping). Phase III - Co-Developing Solutions: Build low-risk, low-cost prototypes of selected concepts and conduct iterative experimentation cycles with users. Host User Feedback Workshops to gather insights and refine solutions until transition-ready. the output of Phase III is Design Prototypes & Experiments (tested solutions) and a Transition Document (implementation-ready plan with ownership, next steps, and success metrics).

### Project 0324 — Adv Combat System Technology

This funding supports the implementation of the Naval Open Systems Architecture (OSA) Strategy. The Navy's implementation of OSA and similar constructs like Modular Open Systems Approaches (MOSA). The OSA transformation effort will be applied to programs of record. Those elements include ensuring that naval systems, families of systems, programs, and prototypes move to MOSA in accordance with DoW Memo 7 Nov 2025, Joint Memo 17 Dec 2024, 10 USC 4402 5 Nov 2025, and SECNAV Instruction 5000.2G (Department of the Navy Implementation of the Defense Acquisition System, 08 April 2022) which mandates that all DoW programs utilize MOSA to field affordable and interoperable systems. This project facilitates a strategic shift to digitally engineered modular systems deployment. This improves innovation and economies of scale throughout the Navy and Marine Corps. This project includes identification of use cases and cost avoidance the benefits as a result of moving the Navy towards an open systems approach, supported by the development of open systems technologies and integrated best operational and technical practices for open systems development within Naval acquisition. Naval MOSA ensures system architectures become extensible and scalable in function, capacity, and workload to meet Service and Joint warfighting requirements. This also includes the identification and development of common software components, functions, reuse methodologies, and extensible product lines. Open architectures set the standard for technology fields to promote interoperability. The Advanced Combat System Technology line advances the principles of modular design and design disclosure, reusable application software, interoperability and secure information exchange, lifecycle affordability and encouraging standardization.

## Mission & acquisition strategy

Project 0303: Tactical Advancements for the Next Generation (TANG) is a Navy-wide innovation project that has expanded throughout the Department of War (DoW) that addresses mission-driven, human-centered challenges for warfighters and developers. TANG drives front-end innovation for national security utilizing emerging technologies including Extended Reality (XR) and Artificial Intelligence/Machine Learning (AI/ML).

This is a non-ACAT program. This project has been a Navy Acquisition Executive directed effort to fundamentally alter the business, technical and policy environment for warfare systems acquisition to result in improved affordability, increased access to innovation, a reduction in time to field, improved operational availability, agility, and promote cultural environment change. The Navy's OSA Enterprise effort is built off of past successes such as the Acoustic Rapid Commercial-off-the-Shelf Insertion (ARCI) program policy statement dated 5 August 2004, the Deputy Chief of Naval Operations (DCNO) requirement dated 23 December 2005, and the Naval OSA Strategy of 2013) and is now being extended and scaled for applicability across the Department of the…
