Indonesian Navy Bolstering Dual-Purpose Assets – Analysis
By Gusty Da Costa
Key Takeaways
- Indonesia Commissions Advanced Submarine Rescue Ship — The KRI Canopus, a 105-meter domestically built vessel, is Indonesia’s first dedicated submarine rescue ship, capable of surveying ocean depths up to 11,000 meters and supporting extended operations with autonomous and remotely operated vehicles.
- Strategic Shift in Undersea Capabilities — The ship reflects a broader regional trend where hydrographic survey and submarine rescue vessels are becoming front-line assets for maritime domain awareness, undersea infrastructure protection, and deterrence in the Indo-Pacific.
- Part of Evolving Naval Competition — As China expands its submarine fleet and other nations (India, Australia, Vietnam, etc.) strengthen undersea forces, Indonesia is investing in comprehensive undersea ecosystem capabilities, moving beyond traditional surface fleet power.
When the Indonesian Navy’s new hydro-oceanographic survey vessel, KRI Canopus, docked at the Kolinlamil Pier in North Jakarta in May 2026, the welcoming party of defense and political leaders underscored that it was no ordinary ship commissioning.
The 105-meter vessel — capable of surveying ocean depths up to 11,000 meters and sustaining operations for 60 days — is Indonesia’s first dedicated submarine rescue ship and most advanced hydrographic survey platform. Equipped with autonomous underwater vehicles and remotely operated vehicles, the KRI Canopus can support operations including submarine path mapping, sea mine detection, security patrols and maritime intelligence, the Indonesian Navy said.
The ship was constructed domestically by PT Pelindo Marine in Batam and outfitted at the Abeking & Rasmussen shipyard in Germany.
Analysts say the KRI Canopus reflects a strategic reshaping of Indo-Pacific naval competition. Traditionally seen as secondary platforms, submarine rescue ships and hydrographic survey vessels have rapidly transitioned into front-line assets across the region. Allies and Partners including Australia, India, the Republic of Korea, Singapore and Vietnam are expanding their undersea forces, elevating the support requirements those fleets require.
At the same time, China’s military is enlarging its submarine fleet, deepening concerns over Beijing’s expansionist ambitions.
The KRI Canopus will serve scientific and military roles, Adm. Muhammad Ali, chief of Indonesia’s naval staff, said at the commissioning.
“Regional navies have fundamentally changed how they view undersea operations,” Dr. Marcellus Hakeng Jayawibawa, an analyst at the Lemhannas Strategic Center in Indonesia, told FORUM. “Where maritime power was once measured by the number of warships and submarines a country possessed, the focus is increasingly shifting to the ability to understand and dominate the undersea environment.”
Hydrographic and oceanographic data are critical, he said, with information on water depth, seabed topography, currents, temperature and underwater acoustics potentially decisive for submarine operations.
Marcellus framed undersea support vessels as essential to a new kind of deterrence — built “not on firepower alone, but on the sustained capacity to operate in a contested domain.”
Maritime domain awareness, including of military and nonmilitary undersea threats as well as surface dangers, is increasingly crucial, according to Indonesian Defense Ministry analyst Pudji Astuti.
In particular, the KRI Canopus reflects a growing imperative to protect the undersea infrastructure upon which modern economies depend. Undersea fiber-optic cables carry virtually all of the world’s data communications, while energy pipelines and offshore installations sit largely invisible on the ocean floor.
Indonesia is not alone in making such investments. India has deployed specialized mother ships such as the domestically developed INS Nistar to support deep-sea operations. Meanwhile, other nations are forming bilateral rescue pacts, with undersea support capabilities serving as instruments of naval diplomacy, Astuti told FORUM.
As maritime competition evolves, Marcellus said, it “will be determined not by which country possesses the most submarines, but by which succeeds in building the most comprehensive and integrated undersea ecosystem.”
