A drawing by the Royal Netherlands Navy of plans to build an armed logistics and supply ship
by John Konrad (gCaptain) The Dutch Ministry of Defense has announced a bold investment of up to €1 billion in two new support vessels that could redefine naval logistics. These ships, each measuring just 174 feet in length and displacing a mere 600 tons, will be operated by a skeletal crew of as few as eight sailors. Compare that to the De Zeven Provinciën-class frigates, which tower over these new vessels at 473 feet and require a crew of around 230. This isn’t merely a downsizing—it’s a seismic shift in naval strategy. The pressing question now is: could this spark an arms race in merchant shipping?
What’s driving this shift? The Royal Netherlands Navy claims its modularity. They aren’t just building ships; they’re creating multi-tool platforms, equipped with containerized weapons and sensors – and other containerized units including lifesaving systems – that can be swapped out for different missions. While modularity on merchant and military logistics ships isn’t new, the plan to arm these vessels with lethal munitions represents a significant departure from tradition.
Historically, merchant ships have been armed for self-defense, and carried offensive weapons up to World War II. Some navies even employed Q-ships—warships disguised as merchant vessels—to lure enemy combatants into a false sense of security before launching a surprise attack. However, the oceans have been relatively peaceful since then, and commercial ships quickly shed their lethality.
Today, even the U.S. Navy’s Military Sealift Command fleet logistics ships, which sail with carrier battlegroups and transit combat zones, are only equipped with small arms, and a few have the mounting systems for the Close-In Weapon System (CIWS) anti-air defense… but none of them have CIWS installed, leaving them vulnerable to drones and anti-ship missiles.
The commercial sector is even more reluctant to arm itself. Shipowners would rather reroute vessels around Africa, burning large amounts of fuel and incurring millions in costs, than install anti-drone and missile defenses to run the gauntlet of Houthi missiles in the Red Sea. Even the Somali piracy, which saw 276 incidents of piracy and armed robbery reported worldwide in 2010, didn’t push shipowners to arm their vessels until after the US-flagged ship Maersk Alabama was attacked and the US Navy stepped in. And even then, they preferred hiring third-party security guards over arming and training their own seafarers.
The Dutch aren’t advocating for arming commercial ships or militarizing civilian seafarers like China has already done but, by arming military-owned and operated supply ships, they are taking a step down a path that could lead to an arms race among merchant vessels.
For NATO nations like the Netherlands, building and maintaining a fleet of traditional warships is a costly endeavor—one that has become increasingly unsustainable in the face of tightening defense budgets, stagnating economic growth, and competing national priorities. The price tag for a single modern frigate or destroyer can run into the billions of dollars, with long lead times and significant lifecycle costs for maintenance and crew. As a result, many NATO navies have seen their fleets atrophy, with fewer ships in service and aging vessels struggling to meet modern threats.
Modern warships are marvels of engineering, packed with weapons systems, sensors, and crew quarters—but they’re also incredibly cramped. Every square foot of a warship’s deck is valuable real estate, dedicated to systems supporting its core missions: power projection, air defense, and anti-submarine warfare. This density leaves scant room for new systems, particularly those needed to counter emerging threats like drone swarms or long-range precision strikes.
In stark contrast, commercial vessels and support ships offer vast, underutilized expanses of deck space and cargo holds. Designed to carry enormous loads of cargo or fuel, these ships can easily accommodate containerized weapons and sensors, making them ideal candidates for modular naval design. A commercial vessel can be reconfigured quickly and cheaply to deploy a range of systems, from anti-air and anti-ship missiles to electronic warfare and drone launch platforms.
The difference in cost between a purpose-built warship and a converted commercial vessel is staggering. For the price of a single modern frigate, a nation could acquire and outfit several commercial ships with advanced weaponry and sensors, creating a formidable force multiplier at a fraction of the cost. And these aren’t just theoretical savings—NATO countries like the Netherlands have been wrestling with budgetary constraints for years, struggling to maintain a credible naval force while addressing other defense priorities. In many cases, this has meant watching their once-formidable fleets dwindle as they retire older ships without replacement.
In this context, the Dutch decision to arm logistics ships starts to make a lot of sense. It’s not just about increasing naval firepower—it’s about expanding capabilities in an economically viable way. By using commercial platforms, the Dutch can deploy a larger, more versatile force without the financial burden of traditional warship procurement. It’s a strategy that leverages the inherent advantages of commercial vessels: their size, capacity, and lower cost.
The idea of arming logistics ships is not just a tactical choice; it’s a strategic statement. It challenges the traditional view of what a support vessel should be and, more importantly, what it can do. This development forces a reconsideration of fleet composition and the role of auxiliary vessels in a combat environment.
For the U.S. Navy and other NATO forces, this move by the Dutch could serve as a blueprint for future fleet design. Imagine a world where the humble supply ship is no longer just a soft target but an active participant in the battlespace, providing not just logistical support but also offensive and defensive firepower. Such a concept could significantly alter naval strategies, especially in contested environments like the South China Sea or the Baltic.
And if the Dutch can do it what’s stopping Russia from arming its existing shadow fleet of merchant ships? In fact, Iran is already turning a containership into a drone aircraft carrier.
Defense of merchant ships is a noble goal in modern combat zones like the Red Sea but this plan isn’t just about bolstering air defense. The Dutch support vessels will also be equipped with ship-launched Harop loitering munitions, effectively transforming them into platforms for precision strikes during amphibious operations. These loitering munitions can patrol the skies for hours, hunting high-value targets like command posts, supply depots, and even unmanned surface vessels. This is a significant leap from traditional naval fire support, offering a level of surgical precision previously reserved for manned aircraft or special operations forces.
Moreover, the vessels’ potential use as motherships for uncrewed underwater vehicles (UUVs) adds another layer of capability. With the growing concern over undersea infrastructure sabotage, from pipelines to communication cables, these armed logistics ships could serve as both protectors and enforcers in critical maritime chokepoints.
The Dutch support vessels aren’t just a complement to their larger, more traditional frigates; they become force multipliers, capable of extending the defensive and offensive reach of the fleet in ways previously unimaginable. With their containerized Barak-ER missiles, these ships can be controlled by the larger De Zeven Provinciën-class frigates, turning the support vessels into floating missile magazines controlled by shooters in the cloud. This level of integration and coordination between different classes of ships is something the broader maritime industry can only dream of, but it may soon become a necessity.
This move could also be a response to the U.S. Department of Defense’s Replicator initiative and its “any-sensor, any-shooter, any-time” concept. These innovations are transforming modern warfare by merging artificial intelligence, autonomous systems, and networked sensors to create a resilient, decentralized kill chain. The aim is to use large swarms of unmanned platforms—like drones and autonomous ships—to deliver real-time targeting data across a vast, distributed network of assets. This setup allows any available shooter, from warships to aircraft and even operators on bases back in the United States, to engage threats dynamically and adaptively, greatly improving battlefield responsiveness and operational flexibility.
If a commercial or logistics ship could launch AI-controlled drone swarms while another fires Tomahawk missiles from containerized systems under the command of a weapons officer in Nevada, their combined lethality would be staggering. Furthermore, commercial vessels outfitted with these weapon containers might be easier to conceal from enemy satellites than a large warship painted haze-gray.
Perhaps the most intriguing aspect of these new support vessels is what they represent for the future of naval warfare—and by extension, the maritime industry. With a crew of just eight, these ships are on the brink of becoming fully uncrewed surface vessels (USVs). The Dutch Ministry of Defense admits that the technology isn’t quite there yet, but it’s only a matter of time. The lessons learned from these nearly uncrewed ships will be invaluable as we move toward a future where autonomous vessels are not just a possibility but a necessity.
The implications for the commercial sector are profound. Imagine a future where container ships, tankers, and bulk carriers not only carry weapons systems but can operate with minimal or even no crew. The potential for naval cost savings is enormous, but so are the challenges, from cybersecurity to the logistics of maintaining and repairing these vessels at sea. The Dutch Navy’s experiment is not just a military one; it’s a test case for the entire maritime world.
While the focus is on the Netherlands, the implications are global. NATO and its allies are increasingly concerned about the threat of underwater sabotage, as demonstrated by the Nord Stream pipeline incidents. The new Dutch vessels will serve as motherships for uncrewed underwater vehicles (UUVs), tasked with monitoring and protecting critical infrastructure like oil and gas platforms and undersea cables. The North Sea, relatively quiet compared to the more volatile regions of the world, is not immune to these threats and needs solutions as soon as possible.
Containerized radar packages, sonar packages, satellite communications equipment, new lifesaving innovations, anti-mine warfare modules… the sky is the limit for what other warship equipment could be containerized and put on a supply ship. But will it work?
This concept of modularity, while promising on paper, has faced significant setbacks in practice, as evidenced by the U.S. Navy’s Littoral Combat Ship (LCS) program. The LCS was originally designed with interchangeable mission modules, allowing a single hull to perform a variety of roles, from mine countermeasures to surface warfare. However, the reality proved far more complex. The modules were difficult to swap out quickly, the ships suffered from reliability issues, and the promised cost savings never materialized. Ultimately, the U.S. Navy had to scale back its ambitions, and the LCS program has been widely criticized as a costly failure. The Dutch Navy’s approach to modularity, while innovative, will need to overcome these same challenges if it hopes to avoid the pitfalls that plagued the LCS and prove that a modular fleet can be both flexible and effective in real-world operations.
The Dutch Navy’s bold investment in modular, armed support vessels signals a potential paradigm shift in naval logistics and strategy. This move, while innovative, raises significant ethical questions and could spark an arms race among merchant ships. By blurring the lines between military and commercial assets, the Netherlands is setting a precedent that other nations may follow, potentially leading to an era where cargo ships are not only defenders but active participants in conflicts. Such a scenario could have far-reaching consequences, fundamentally altering the rules of engagement at sea and escalating tensions in an already volatile global maritime environment.
