From Awareness to Presence: A Comprehensive Philippine Maritime Strategy

By Karl Garcia

Executive Summary

The Philippine Navy’s modernization is outpacing its shore infrastructure, creating an operational gap that threatens readiness, sovereignty, and fiscal discipline. Simultaneously, the nation faces a strategic challenge: converting legal rights and maritime domain awareness into sustained, credible presence. The solution requires integrating three elements: (1) a tiered basing and access strategy combining sovereign bases, modular infrastructure, and controlled commercial access; (2) innovative platforms that enable persistent presence without overt militarization; and (3) institutional frameworks that align security, economic, and environmental objectives. Implemented correctly, this approach enables immediate operational support while preserving long-term strategic independence under fiscal constraints.

The Strategic Context: Beyond Awareness

In his recent State of the Nation Address, President Ferdinand “PBBM” Marcos Jr. emphasized the critical importance of Maritime Domain Awareness (MDA)—a timely affirmation of the Philippines’ identity as an archipelagic and maritime nation. Yet awareness alone is insufficient.

The South China Sea remains one of the world’s most complex maritime theaters. The Nine-Dash Line intrudes deep into Philippine Exclusive Economic Zones, directly contradicting UNCLOS principles. Power asymmetry forces smaller claimant states to navigate complex dynamics, balancing international law, diplomacy, and selective partnerships to offset China’s material and coercive advantages.

The central dilemma: How can the Philippines convert legal rights and maritime awareness into sustained, credible presence and long-term strategic advantage?

The answer lies not in choosing between military presence or diplomatic engagement, but in building a comprehensive strategy that integrates infrastructure, innovative platforms, and governance reform.

Part I: The Basing Infrastructure Challenge

The False Binary That’s Holding Us Back

Philippine naval policy discussions often get trapped in an unproductive debate: Should we rent commercial port space or build our own bases? This framing misses the point entirely.

Renting isn’t cheaper—it’s just deferred cost. Recurring port fees eventually cannibalize modernization funds. Meanwhile, ownership without proper sequencing is unrealistic given budget constraints and the urgency of operational needs.

The real question isn’t rent versus own. It’s: How do we build operational sovereignty incrementally while maintaining readiness today?

Strategic Coherence: Connecting Geography to Security

An effective basing strategy must connect three critical elements:

  1. Basing geography → operational response times – Where you position assets determines how quickly you can respond to threats
  2. Infrastructure lag → fiscal and sovereignty risk – Delays in building proper facilities force expensive temporary solutions and create dependencies
  3. Port access policy → national security doctrine – Who controls your ports shapes your strategic autonomy

Most Philippine Navy discussions stay tactical—debating pier lengths and berthing capacity. What’s needed is strategic thinking that remains concrete without becoming abstract.

The Subic Question: Geography, Not Nostalgia

Subic Bay deserves special attention, not because of its historical legacy, but because of its strategic geometry:

FactorSubic BayCavite (Sangley/Fort San Felipe)
Water depthDeep, future-proofConstrained
Expansion spaceHighSeverely limited
Civilian conflictLowVery high
Wartime survivabilityBetterPoor
Strategic roleFleet & sustainmentTraining, admin, legacy

Cavite cannot remain the fleet center, regardless of sentimental attachment. The geography simply doesn’t support modern naval operations at scale.

Subic isn’t a magical solution—but it is a Tier 1 anchor around which a distributed strategy can be built.

Forward Operating Bases: Persistence, Not Permanence

The archipelagic nature of Philippine territory demands forward presence. But these Forward Operating Bases shouldn’t try to replicate Subic-scale facilities.

Their core function is persistence, not permanence: refueling, rearming, ISR support, maritime domain awareness, and Marine littoral operations. Designed around modular infrastructure, each FOB can scale incrementally as threat conditions and funding allow.

Think of them as operational nodes, not static fortresses. This approach operationalizes archipelagic defense by enabling distributed maritime operations without waiting for fixed-base completion.

Part II: The Sierra Madre Dilemma and Alternative Solutions

The Limits of Symbolic Presence

The BRP Sierra Madre, intentionally grounded on Second Thomas Shoal in 1999, remains a powerful symbol of Philippine resolve. As a commissioned naval vessel, it continues to underpin Manila’s legal and sovereign claim under UNCLOS. However, its deteriorating condition raises serious operational, humanitarian, and strategic concerns:

  • Escalating Chinese Coast Guard harassment during Philippine resupply missions
  • The physical degradation of the ship and risks to personnel
  • Arguments for enhanced presence to support deterrence and sustain logistics

Proposals to replace the Sierra Madre with a permanent Forward Operating Base highlight the need for sustained presence, yet a fixed military base also carries escalation risks, legal complications, and high lifecycle costs—prompting the need for alternative approaches.

Marine-Multifunctional-Modular-Mobile (M4) Platforms: A Strategic Alternative

An emerging and underexplored option lies in Marine-Multifunctional-Modular-Mobile (M4) platforms—flexible, civilian-oriented systems that blur the line between security, sustainability, and development. These platforms can integrate:

1. Renewable Energy Generation
Wind, solar, wave, and tidal systems combined with onboard storage

2. Aquaculture and Blue Economy Applications
Co-locating fisheries, food production, and research with offshore platforms

3. Coastal and Maritime Protection
Serving as breakwaters or buffer structures while supporting surveillance and logistics

4. Desalination and Water Treatment
Providing freshwater support for maritime operations and nearby communities

5. Tourism, Research, and Civil Presence
Reinforcing sovereign presence through continuous civilian and scientific activity

Crucially, M4 platforms offer persistent presence without overt militarization, aligning well with UNCLOS norms and reducing escalation risks. They operationalize the distinction between maritime boundaries (legal lines) and maritime frontiers (zones of actual presence and administration)—a concept emphasized by LCDR Arnold Enriquez, PN (Ret.).

Strategic Advantages of M4 Integration

M4 platforms complement traditional naval infrastructure by:

  • Demonstrating effective administration – The ICJ’s Pedra Branca case established that sovereignty derives from demonstrable acts of administration, not historical assertions alone
  • Sustaining civilian presence – Continuous occupation strengthens legal claims under UNCLOS Article 60 and customary international law
  • Creating economic justification – Blue economy activities provide fiscal sustainability for platforms that also serve security functions
  • Reducing escalation risk – Civilian-primary platforms are harder to characterize as military provocations
  • Enabling strategic flexibility – Mobile platforms can be repositioned as circumstances change

Part III: A Comprehensive Three-Tier Framework

The path forward integrates traditional basing, modular infrastructure, and innovative platforms:

Tier 1: Sovereign Fleet Base (Subic)

  • Deep-water fleet sustainment
  • Shipyard and maintenance
  • Long-term strategic anchor
  • Power projection capability

Tier 2: Forward Operating Bases (Dispersed)

  • Maritime domain awareness
  • Rapid response capability
  • Modular, scalable infrastructure
  • Integration with Coast Guard operations

Tier 3: M4 Platform Network (Offshore)

  • Persistent civilian-military presence
  • Blue economy integration (aquaculture, energy, research)
  • Mobile and reconfigurable
  • UNCLOS-compliant sovereignty reinforcement
  • Environmental monitoring and protection

Tier 4: Controlled Commercial Access

  • Routine logistics support
  • Training and administrative functions
  • Clear security protocols and agreements
  • Temporary measure, not strategic dependency

Part IV: Implementation Challenges and Institutional Reform

The Hidden Risk: Inter-Agency Friction

Infrastructure delays aren’t just about money or technical capacity. They’re often rooted in inter-agency friction:

  • Local government units versus Department of National Defense (zoning, reclamation, airports)
  • Philippine Ports Authority versus Philippine Navy (port control)
  • Civil Aviation Authority versus Navy (Sangley conflicts)
  • Public-Private Partnership laws not designed for military modularity

Framing these delays as structural rather than incompetence matters politically. It points toward governance reforms, not just budget increases.

Critical Implementation Requirements

Regulatory Alignment
Harmonizing maritime, environmental, energy, and security regulations while incentivizing private participation in M4 platforms

Technological Readiness
Leveraging advanced materials, autonomous systems, and digital monitoring for both fixed bases and mobile platforms

Economic Viability
Developing innovative PPP models and conducting full lifecycle cost analyses that account for dual-use benefits

Environmental Safeguards
Measuring impacts, protecting marine ecosystems, and quantifying ecosystem services—particularly for M4 deployments

Stakeholder Engagement
Ensuring buy-in from local communities, fishing industries, energy sectors, and regional partners

What Must Be Avoided

Clarity about what not to do is just as important:

Turning temporary leases into permanent dependence – Short-term port solutions become long-term strategic traps

Allowing recurring fees to cannibalize modernization – Operational costs shouldn’t consume capital budgets

Hosting sensitive systems in ports with unclear ownership – Security requires unambiguous control

Designing FOBs as static targets – Survivability demands flexibility and mobility

Deploying M4 platforms without civilian integration – Security-only platforms lose UNCLOS protection and economic sustainability

Part V: Learning From Regional Approaches

Expert Perspectives on South China Sea Management

Prof. Pankaj Jha (2020) advocates for robust ASEAN-led Code of Conduct, trilateral engagements, Standard Operating Procedures, and a South China Sea-specific Treaty of Amity and Cooperation.

Mark J. Valencia questions sustained ASEAN unity against China, advocating pragmatic arrangements that acknowledge Chinese interests while preserving regional stability.

Bill Hayton argues for ICJ dispute resolution, drawing on the Malaysia–Singapore Pedra Branca case where sovereignty was determined by demonstrable acts of administration.

LCDR Arnold Enriquez, PN (Ret.) emphasizes the distinction between maritime boundaries (legal lines) and maritime frontiers (zones of effective presence), noting that the Philippines–Indonesia maritime boundary agreement illustrates how disciplined diplomacy produces durable outcomes.

The Philippine Advantage

The Philippines can synthesize these approaches through a unique strategy that:

  • Maintains legal primacy (2016 Arbitral Award)
  • Builds effective administration (M4 platforms, FOBs)
  • Pursues selective partnerships (U.S., Japan, Australia)
  • Develops economic integration (blue economy, energy)
  • Strengthens regional diplomacy (ASEAN, bilateral agreements)

Conclusion: From Awareness to Strategic Advantage

The Philippines’ maritime challenge is no longer one of awareness alone, but of sustained, credible, and lawful presence. This requires moving beyond false binaries—rent versus own, military versus civilian, awareness versus presence—to embrace integrated solutions.

The strategic framework:

  1. Sovereign basing that provides fleet sustainment and power projection (Subic)
  2. Distributed FOBs that enable rapid response and domain awareness
  3. M4 platforms that sustain presence through civilian-military integration
  4. Institutional reform that removes friction between security and development agencies
  5. International partnerships that amplify capability without compromising sovereignty

Sovereignty is operational control, not land titles alone. It’s demonstrated through continuous presence, effective administration, and the integration of security with economic and environmental objectives.

The modernization of the Philippine Navy is already happening. The question is whether strategic infrastructure—both traditional and innovative—will keep pace, or become the limiting factor that turns new ships and legal victories into symbols rather than operational advantages.

By integrating legal strategy, diplomatic engagement, modular basing, and innovative platforms, the Philippines can advance a more resilient maritime posture—one that reinforces sovereignty, supports environmental stewardship, and contributes to long-term regional stability in the South China Sea.

This isn’t choosing between awareness and action. It’s converting awareness into sustained strategic advantage.
