Sean Duffy’s MARAD initiative may look like another Trump-era energy dominance announcement, but beneath the politics lies a serious industrial question: can the United States build the regulatory, shipyard, insurance and port framework needed to make nuclear-powered merchant ships commercially viable before Asia takes the lead? //
The real story behind the announcement made by U.S. Transportation Secretary Sean P. Duffy and the Maritime Administration on 7 May is not that America has discovered nuclear propulsion. It is that Washington has finally recognized maritime nuclear power as a shipbuilding, logistics, insurance, port-access and national-security race, and has decided to enter it. MARAD’s Request for Information, with comments due by 5 August 2026, asks industry to help develop a U.S.-built, scalable, commercially viable SMR model for marine transportation. That is a materially different ambition from funding a reactor demonstration. It is an attempt to build a complete commercial ecosystem. //
Shipping is uniquely suited to nuclear propulsion. The energy density argument for maritime nuclear propulsion is more compelling than for almost any other transport sector. A modern ultra-large container ship consumes between 250 and 350 tonnes of fuel per day at sea. Over a 25-year operational life, fuel can represent billions of dollars in lifecycle cost. Bunker storage, fuel treatment systems, purifier rooms, sludge handling, emissions scrubbers and the growing infrastructure of alternative-fuel compliance consume enormous volumes of space, capital and crew time. Nuclear propulsion potentially eliminates most of that complexity, a reactor fuelled for two decades or more fits within a containment space that returns cargo volume to its owners and voyage economics to their prior simplicity. //
Thorium, increasingly discussed as an alternative fuel cycle, offers further advantages. Thorium-232 converts under neutron bombardment to fissile uranium-233, is three to four times more abundant than uranium in the earth’s crust, produces significantly less long-lived radioactive waste, and is far less susceptible to weapons proliferation. Molten salt reactor designs, which dissolve thorium in liquid fluoride salt that also acts as the coolant, operate at atmospheric pressure rather than under the high-pressure steam conditions of conventional light-water reactors, removing explosive decompression risk. An approval in principle for a nuclear-powered LNG carrier using molten salt technology was granted in 2025. //
The United States now accounts for approximately 0.1 per cent of global commercial ship production. A single Chinese state shipbuilder built more vessels by tonnage in 2024 than the entire U.S. industry has produced since 1945. //
The U.S. has become marginal in commercial construction outside naval programmes, which is precisely why the MARAD announcement repeatedly frames SMR development as a mechanism for rebuilding domestic yards, creating strategic engineering employment, and reconnecting maritime and defence industrial capacity. //
While Europe debates how to tax shipping emissions, the United States is beginning to ask who will build and power the next generation of ships altogether.
South Korea is not waiting for that question to be answered. HD Hyundai has unveiled a 15,000 TEU-class SMR-powered containership concept and is working with ABS on nuclear-electric propulsion systems potentially supplying up to 100 megawatts. China has explored molten salt reactor ship concepts and is investing heavily in thorium-based systems. Russia already operates the only nuclear-powered commercial vessels in service, alongside its Arctic icebreaker fleet.
The dimensions of a shipping container are based on standards that ensure there are no issues during shipping. ISO sets the standard for shipping container dimensions.
- General-purpose containers are 8.5 feet (2.59m) high and 8 feet (2.43m) wide. They come in two lengths; 20 feet (6.06m) and 40 feet (12.2m).
- A 40ft high-cube shipping container or extra tall shipping containers are available at 9.5 feet (2.89m).
- 10 feet (2.99m) and 8 feet (2.43m) ISO containers are also available.
ISO 1496-1 originally set the shipping container stacking weight limit at 192,000 kg (423,288 lbs) across the four corner posts. A 2005 revision increased the rated capacity to 213,360 kg (470,400 lbs) for new-build containers. Both figures assume a 1.8G dynamic acceleration factor, meaning the container is rated to hold that load even under the rolling, pitching, and heaving forces of ocean transit. On stable ground, the effective safety margin is even larger. //
A two-high stack of empty containers presents roughly 320 square feet of windward surface area on the long side. At 90 mph wind speed, that surface generates approximately 4,100 lbs of lateral force. Without twist-locks anchoring the upper container, friction alone between the flat steel surfaces will not hold.

Among the many options you have when it comes to getting the right modified shipping container is choosing from a selection of structures that are ready to ship in three weeks or less.
Trump has already said the Navy will escort ships through Hormuz “if necessary.” If the same reflagging requirement applies, every European and Asian tanker that wants a U.S. escort would need to fly the American flag.
Think about what that means for the SHIPS Act, the Jones Act, the U.S. flag fleet, and CMA CGM’s unfulfilled promise to triple its U.S.-flag vessels, Greenland. Hormuz becomes the forcing function for everything Trump’s maritime agenda could not achieve through legislation or diplomacy.
Meanwhile, Iran is selectively letting ships through. Turkish, Indian, Chinese, and some Saudi tankers have been permitted to transit via Iranian territorial waters. About eighteen tankers, mostly Chinese, have done so according to Lloyd’s. Western-allied ships are blocked.
The “closure” is really a sorting mechanism. Iran decides who trades and who does not. Unless the U.S. Navy reopens it for everyone. On America’s terms.
That’s the decision the world has to make, let Iran pull up a tollbooth or stop blocking Trump’s maritime plans. //
While TV oil analysts focus on the global price of oil, the real experts in Houston are watching something different: the fracturing of the global energy market.
The real threat is not $200 oil. It’s a fracture of the system. It is cheap energy in export nations and ruinous energy costs in places far from reserves. It’s $2 oil in the Persain Gulf, $20 dollar oil in the Gulf of America and $2,000 oil in the UK. //
One global price only works if there is a surplus of tankers to arbitrage differentials. Before the Iran strikes, that surplus was razor-thin. Now, with supertankers stuck in the Gulf, it is gone. //
Meanwhile, California has been closing refineries and blocking pipelines, forcing gasoline imports from South Korea on ships with dayrates that are skyrocketing. Govenor Newsom, the leading canidate for President in 2028, is irrate. New England imports LNG and diesel by ship. If Hormuz stays closed, prices spike in those states. Deep blue states. Red state energy costs fall. Blue state costs rise. Europe capitulates on major policy disputes between now and the midterms. //
The strongest version of this thesis is not “Trump is playing 4D chess.” It is that the administration holds more options than anyone realizes, and the insurance mechanism, not the Navy, is the real lever of power.

Bahrain is the only regional country playing. This is significant because Egypt has a major role in CTF 153, and command of CTF 153 has rotated between US and Egyptian admirals. If this is a test of strength between the US and Iran (and China), the fact that Egypt and Saudi Arabia have bowed out shows which way the political winds are blowing.
The Chinese have six warships stationed in the Red Sea/Persian Gulf area of operations. They are not participating, and they are not aiding commercial traffic under attack. Draw your own conclusions. //
In my view, this is just another case of the Biden national security apparatus trying to give the impression of doing something while doing nothing. The obvious reason they are doing nothing is that Biden, Sullivan, etc., don't want to offend Iran. Instead of looking after our national interests (safe and rapid transit of sea lanes) and showing confidence and leadership, the Biden White House has elected to show weakness and uncertainty. Nothing good will come from this.
About 10 percent of the world's sea traffic goes through the Red Sea. Rerouting ships around the Cape of Good Hope lengthens the trip by about twelve days, adding considerable cost to freight and disrupting supply chains. The frequency of the attacks has led two of the world's largest shipping companies, Maersk and Hapag-Lloyd, to order their ships to avoid the Red Sea until further notice; see Major Shipping Lines Avoid Red Sea; Is It Just the Houthis or Should We Be Looking Deeper?.
The new coalition, to be called Operation Prosperity Guardian (is it too much to ask that we begin calling military operations things that don't suck?), will involve ships of several nations. The concept of the operation is not yet known, but it is expected to combine the protection of individual ships with convoys. In fact, very little is known about the operation (number of ships, which countries, when it starts, its Mission) other than its name.
Shipping companies are taking it seriously. Automatic Identification System beacons are showing that Maersk and Hapag-Lloyd ships are forming up for a convoy. //
As I wrote in Major Shipping Lines Avoid Red Sea, Is It Just the Houthis, or Should We Be Looking Deeper? we need to look beyond the possibility of the Israel-Hamas War expanding if Israel carries out retaliatory strikes against Yemen. This is an exercise in testing the US and NATO response to a critical maritime route being obstructed and the tactics, techniques, and procedures we will use in keeping the sea lanes open.
