The capacity to carry the nation's trade: merchant fleets and registries, port and terminal operators at home and abroad, and the freight and logistics providers that constitute a services economy in their own right.
The Capability Development Index tracks the events that move a capability — operational use, technical breakthroughs, procurement decisions and the industrial base behind them — and places each on the record with the date it happened.
Recent developments cover the current period. Historical developments are the inflection points that produced Maritime & Logistics Services as it stands today.
Lothal, in what is now Gujarat, served as a major port of the Indus valley civilisation from around 3700 BCE. It is among the earliest documented examples of purpose-built maritime trade infrastructure.
The port of Piraeus served as the base for the Athenian fleet that fought the Persians at Salamis in 480 BCE. It illustrates how port capacity underpinned naval as well as commercial maritime power in the ancient Mediterranean.
The phenomenon of the Italian maritime republics began with Amalfi and Gaeta, which quickly reached their commercial heyday. Their fleets and harbours pioneered the revival of Mediterranean trade after the early Middle Ages.
From the 10th century Amalfi, Genoa, Pisa and Venice built fleets both for protection and to support extensive Mediterranean trade networks. This restored maritime commercial contacts that had been interrupted during the early Middle Ages, establishing the port city as an engine of long-distance trade.
Innovations including the magnetic compass, watertight bulkheads and sternpost rudders let Chinese vessels sail further and more reliably, extending trading fleets deep into the Indian Ocean and giving Chinese ports a shipbuilding capability unmatched elsewhere at the time.
After the 11th century Amalfi and Gaeta declined rapidly while Genoa and Venice rose to dominance. The shift concentrated Mediterranean shipping capacity in a small number of large port states.
Cities from London to Novgorod coordinated berths, warehouses and cog-ship sailings around the Baltic and North Sea under shared commercial law, an early demonstration that linked port capacity across many sovereign territories could function as one system.
Pisa followed Genoa and Venice into prominence, experiencing its most flourishing period in the 13th century. Ancona and Ragusa allied in the same era to resist Venetian sea power.
Following the 14th century Pisa declined to the point of losing its autonomy, while Venice and Genoa retained control of navigation. Ragusa and Ancona ranked behind them in shipping capacity.
Ancona and Ragusa reached their commercial peak in the 15th century, ranking behind Venice and Genoa among Italian and Adriatic maritime powers. Their rise showed that secondary ports could still capture significant Mediterranean trade.
Fleets of more than 300 ships, some far larger than anything Europe would build for another century, sailed from China to South-East Asia, India, Arabia and East Africa, demonstrating a state shipbuilding and fleet capacity without contemporary rival.
With Ancona's loss of autonomy in the 16th century, only Venice, Genoa and Ragusa remained as independent maritime republics. They enjoyed splendour until the mid-17th century, then declined slowly until the Napoleonic invasion ended them.
The VOC combined a chartered monopoly, permanent shipyards and purpose-built harbour facilities to run scores of vessels between Europe and Asia at once, establishing the template of corporate-scale shipping and dedicated port infrastructure that followed.
From the 20th century icebreaker vessels allowed ports in the Baltic Sea and similar high-latitude waters to operate throughout the year. Earlier winter access problems had prompted Russia to expand its territory towards the Black Sea in search of ice-free harbours.
Since 1947 the coats of arms of Amalfi, Genoa, Pisa and Venice have appeared on the flags of the Italian Navy and Italian Merchant Navy. The gesture codified the four cities as the canonical maritime republics.
The registry let shipowners flag vessels under Liberian law regardless of where the owner was based, a model soon followed by Panama and others, concentrating a large share of the world's merchant fleet under open registries rather than national flags.
Up to the 1950s the Port of London on the Thames was a major international port. Changes in shipping practice, notably the adoption of containers and much larger vessels, drove its subsequent decline and shifted capacity to deepwater container terminals elsewhere.
The automated Phase IV terminal handled 29,910 TEU in a single call, while the port as a whole reached a daily high of 187,312 TEU; first-half 2026 volumes topped 28 million TEU, up 6.2% on the year.
The government planned to auction the Tecon 10 concession at Latin America's busiest port for a 25-year term, following a $275 million investment by DP World months earlier to expand cargo-handling capacity at the same complex.
Greenfield terminal projects at Lekki in Nigeria, Bagamoyo in Tanzania and Kribi in Cameroon drew combined commitments exceeding that figure, extending a wave of foreign-financed port construction that is reshaping Sub-Saharan Africa's maritime gateways.
Completion of the New Priok Eastern Access road significantly shortened queues at Tanjung Priok, the gateway that handles the largest share of the country's container traffic, as Jakarta separately advanced plans for a new port opposite Singapore.
The city-state topped the Xinhua-Baltic shipping centre index for a 13th consecutive year, backed by a S$15 billion commitment to automate the Tuas Megaport, which is being built in phases towards an eventual 65 million TEU capacity.
The Red Sea container terminal, designed for an eventual 1.5 million TEU capacity by 2030, began handling commercial cargo, positioning the planned industrial city as a future competitor to Jebel Ali and other established Gulf hubs.
New contracts in the first half of 2026 reached 121 million deadweight tonnes, up 173% on the same period last year and already ahead of the whole of 2025, giving Chinese yards an 82% share of global ordering.
The new terminal's 24-metre natural depth allows ultra-large container vessels to call without dredging, and it was designed to handle around 1 million TEU initially, reducing India's reliance on foreign transshipment hubs such as Colombo and Singapore.
The programme combined public and private investment across nine port projects, with work at Manzanillo, the country's busiest container gateway, moving from land preparation into a multi-year construction phase running into 2028.
COSCO Shipping holds a majority stake in the deep-water terminal, which offers South America's first direct container service to Asia and is intended to bypass congested hubs and cut weeks off transpacific shipping times for Andean exporters.
Business intelligence provider Visiongain estimated that spending in the smart ports market would reach $1.5 billion in 2019. The figure marked the emergence of digital and automated systems as a distinct component of port capacity investment.
Vessels of nearly 18,000 TEU entered the Asia-Europe trade, forcing ports from Rotterdam to Tanjung Pelepas to deepen berths, strengthen quay cranes and widen turning basins to accommodate a new generation of ultra-large container ships.
Shanghai became the world's busiest port by cargo tonnage in 2009 and, in 2010, overtook Singapore as the world's busiest container port for the first time. Rapid growth in Chinese manufacturing and export volumes drove the increase, confirming the shift of the centre of gravity in global port capacity from South-East Asia to the Chinese mainland.
The Moroccan port of Tangier Med went into service in July 2007. It became the largest port by capacity on the Mediterranean and in Africa, marking a significant addition to southern-shore transhipment capacity.
Vessels built too wide for the century-old canal, beginning with a class ordered by American President Lines, forced ports worldwide to plan berths, cranes and channels around ship dimensions no longer bounded by a single waterway.
A common standard for container size and corner fittings let the same box transfer between ship, rail wagon and lorry without repacking, a prerequisite for the intermodal terminals and gantry cranes that define port capacity today.
The converted tanker carried 58 containers on a single deck, the first voyage of a standardised box that would eventually replace break-bulk cargo handling and remake ports around cranes, stacking yards and container berths rather than warehouses.
