(DEFENCE SECURITY ASIA) — Babcock International has announced a new agreement granting Indonesia licenses for two additional Arrowhead 140 frigates, a development that marks a decisive inflection point in Southeast Asia’s evolving maritime power balance and firmly embeds Jakarta’s naval modernisation drive within a broader Indo-Pacific geostrategic contest increasingly defined by blue-water power projection, defence-industrial sovereignty, and calculated alliance diversification.”

This agreement represents the first tangible execution milestone under the ambitious £4 billion Maritime Partnership Programme, valued at approximately US$5.08 billion or RM23.9 billion, formally signed between the United Kingdom and Indonesia in November 2025, translating strategic intent into concrete industrial and naval outcomes with long-term regional implications.

The strategic weight of this development is underscored by Babcock Chief Executive Officer David Lockwood’s assertion that, “This first work order, within this landmark framework, signals the importance of the pace and progress needed to deliver President Prabowo Subianto’s maritime transformation and underpins the growing success of our Arrowhead 140 export design,” a statement that places operational tempo and political intent at the centre of Indonesia’s naval recalibration.

Equally revealing is Babcock’s institutional framing of the deal as one that “builds on the two Arrowhead 140 licences exported in 2021 and follows the recent launch of the first Merah Putih class frigate in Indonesia, underpinning the growing momentum in our frigate export,” highlighting continuity rather than episodic procurement as the programme’s defining feature.

President Prabowo Subianto’s long-standing emphasis on maritime sovereignty, rooted in Indonesia’s obligation to secure an Exclusive Economic Zone exceeding six million square kilometres, transforms these frigates from mere fleet additions into instruments of national power projection, resource protection, and deterrence credibility across contested maritime corridors.

“I met with the CEO of Babcock. We are pleased to proceed with the maritime partnership. I think this is very important and strategic for Indonesia. This is a vital part of our maritime economic development.”

The Arrowhead 140’s selection reflects a calculated convergence of affordability, modularity, and combat scalability, enabling Indonesia to pursue blue-water ambitions without surrendering industrial autonomy, fiscal discipline, or future upgrade pathways in an era of rapidly evolving naval warfare doctrines.

By anchoring construction at PT PAL with extensive technology transfer provisions, the programme simultaneously advances Indonesia’s Minimum Essential Force doctrine while reshaping the domestic defence-industrial ecosystem into a more resilient, export-capable, and strategically autonomous enterprise.

Taken together, this agreement signals that Indonesia’s naval modernisation is no longer aspirational or incremental, but structurally embedded within a long-term maritime transformation strategy designed to reposition the archipelagic state as a decisive Indo-Pacific naval actor.

Two Arrowhead 140 frigates are currently under construction at state-owned shipbuilder PT PAL Indonesia under the Indonesian Navy’s Merah Putih programme.

On 18 December 2025, the first hull was formally named and launched, marking a key milestone in the programme.

The vessel is the lead ship of a two-frigate class being constructed by PT PAL Indonesia to the Arrowhead 140 design developed by Babcock.

Construction of KRI Balaputradewa commenced with a steel-cutting ceremony in December 2022, followed by keel laying in August 2023.

From Export Concept to Strategic Industrial Anchor

The Arrowhead 140’s Indonesian journey began in September 2021 when Babcock secured its first export design contract, establishing a precedent that transformed the platform from a European general-purpose frigate concept into a globally competitive naval architecture tailored for emerging maritime powers.

The licensing agreement signed with PT PAL at the Defence and Security Equipment International exhibition enabled Indonesia not merely to acquire hulls, but to internalise advanced frigate construction competencies previously concentrated within European shipbuilding ecosystems.

Babcock CEO David Lockwood’s declaration at the time that, “Today is a really exciting moment for Babcock and our frigate export program, as we sign the design license with PAL for two new frigates for the Indonesian Navy,” captured the dual commercial and strategic significance of transferring sovereign shipbuilding capability rather than exporting finished warships.

Derived from the Danish Iver Huitfeldt-class and refined as the basis for the Royal Navy’s Type 31 Inspiration-class, the Arrowhead 140 integrates survivability, payload capacity, and lifecycle affordability into a single platform optimised for coalition interoperability and national customisation.

Indonesia’s designation of the design as the Merah Putih class elevated the frigates into symbols of national identity, reinforcing the political narrative that naval modernisation and industrial self-reliance are inseparable components of state sovereignty.

The launch of KRI Balaputradewa (322) on 18 December 2025 marked Indonesia’s entry into the limited cohort of nations capable of domestically constructing large multi-role frigates, a milestone with enduring strategic and industrial ramifications.

Defence Minister Sjafrie Sjamsoeddin’s emphasis on “maritime sovereignty and industrial independence” during the launch ceremony articulated the programme’s role as a foundational pillar of Indonesia’s long-term defence posture rather than a discrete procurement initiative.

By embedding high local content targets consistent with the Minimum Essential Force doctrine, the programme operationalises Indonesia’s ambition to convert defence expenditure into sustainable industrial capability rather than recurring foreign dependency.

 

The New Agreement and the Architecture of the Maritime Partnership Programme

The agreement announced on 21 January 2026 formalises the sale of two additional Arrowhead 140 design licences, expanding Indonesia’s future frigate force from an initial pair into a coherent squadron-level capability designed for sustained maritime presence.

This expansion is nested within the broader Maritime Partnership Programme, a £4 billion framework valued at approximately US$5.08 billion or RM23.9 billion, encompassing naval construction, maritime infrastructure, fisheries support, and long-term industrial cooperation.

The Letter of Intent signed between Babcock and representatives of President Prabowo’s administration signals political alignment at the highest level, ensuring programme continuity beyond electoral cycles and bureaucratic inertia.

By committing to local construction at PT PAL, the agreement consolidates technology transfer, workforce development, and supply-chain localisation as non-negotiable pillars of Indonesia’s naval strategy.

The integration of Turkish missile, sensor, and combat management systems reflects Indonesia’s deliberate diversification strategy, reducing exposure to political conditionality while maximising cost-effectiveness and upgrade flexibility.

This multi-vendor architecture mirrors broader Asian defence procurement trends, where modular integration replaces monolithic supplier dependence as the preferred risk-management model.

From Babcock’s perspective, the deal sustains high-value design and engineering work at Rosyth, preserving skilled employment while reinforcing the Arrowhead 140’s status as a flagship British defence export.

Financially, analysts assess that the two additional frigates could exceed US$1 billion in total programme value, equivalent to approximately RM4.7 billion, once systems integration, training, and lifecycle support are fully accounted for.

Combat Architecture and Operational Reach of the Merah Putih Class

Displacing approximately 5,700 tonnes and measuring 138.7 metres in length, the Arrowhead 140 provides Indonesia with a hull form optimised for endurance, seakeeping, and multi-mission flexibility across littoral and blue-water environments.

The CODAD propulsion architecture, driven by four MTU diesel engines, delivers speeds approaching 28 knots and a range of 9,000 nautical miles at cruising speed, enabling sustained patrols across Indonesia’s dispersed archipelagic geography.

Such endurance directly addresses the operational reality of safeguarding over 17,000 islands, critical sea lines of communication, and offshore energy infrastructure spread across vast maritime distances.

The Merah Putih class’s modular weapons architecture allows tailored armament configurations, including a 57mm or 76mm main gun, vertical launch systems for surface-to-air missiles, and advanced anti-ship missile options such as Atmaca or Exocet.

Anti-submarine warfare capability is reinforced through hull-mounted sonar, embarked helicopters such as the AS565 Panther or Seahawk, and torpedo systems designed to counter increasingly sophisticated undersea threats.

Advanced sensors, including modern AESA radars and network-centric combat management systems, position the frigates as maritime domain awareness hubs capable of integrating with joint and coalition task forces.

Compared with Indonesia’s existing Sigma-class frigates, the Arrowhead 140 offers superior payload margins, electrical generation capacity, and future growth potential.

This adaptability ensures relevance against evolving threats, including unmanned systems, hypersonic missiles, and distributed maritime operations that define contemporary naval warfare.

Geostrategic Significance in a Contested Indo-Pacific Maritime Order

Indonesia’s decision to expand its Arrowhead 140 fleet unfolds against intensifying strategic competition in the South China Sea, where overlapping claims and grey-zone coercion increasingly test regional stability.

Enhanced frigate capability strengthens Indonesia’s ability to conduct persistent presence operations, enforce sovereign rights, and contribute meaningfully to regional maritime security architectures.

The programme enhances interoperability with partners such as Australia, Japan, and the United States, reinforcing Indonesia’s strategic autonomy while deepening defence cooperation.

For the United Kingdom, the deal exemplifies post-Brexit defence diplomacy, leveraging naval exports to sustain influence across the Indo-Pacific without permanent force deployments.

The Arrowhead 140’s export success also counters China’s growing defence market penetration, particularly where Beijing promotes platforms such as the Type 054A as cost-competitive alternatives.

Indonesia’s balanced procurement approach allows it to modernise without aligning exclusively with any single power bloc.

The programme also strengthens Jakarta’s leverage in multilateral forums, where credible naval capability translates into diplomatic weight.

Collectively, these dynamics reposition Indonesia as a stabilising maritime power rather than a peripheral coastal state.

Industrial Risk, Fiscal Sustainability, and the Road Ahead

Despite its promise, the Arrowhead 140 programme faces structural challenges, including global supply-chain volatility, skilled labour constraints, and complex systems integration across multiple international vendors.

Indonesia’s defence budget, hovering near 0.8 percent of GDP, must reconcile naval expansion with competing air and land force modernisation priorities.

The original US$1.1 billion foreign loan, equivalent to approximately RM5.17 billion, underscores the financial intensity of advanced naval procurement.

PT PAL’s ability to scale production while maintaining quality will determine whether Indonesia emerges as a regional shipbuilding hub or encounters delivery bottlenecks.

Environmental sustainability and lifecycle efficiency are also emerging considerations as navies confront climate-driven operational demands.

Future expansion to six or eight frigates under subsequent Minimum Essential Force phases would solidify Indonesia’s transition toward a balanced blue-water fleet.

Trilateral collaboration involving the United Kingdom, Indonesia, and Turkey could further accelerate innovation in networked and hybrid naval warfare systems.

Ultimately, the Arrowhead 140 programme is less about hull numbers than about institutional transformation.

As David Lockwood observed, the agreement reflects “the pace and progress needed” to realise maritime transformation, positioning Indonesia at the forefront of Southeast Asia’s evolving naval order. — DEFENCE SECURITY ASIA
