Riyadh / Rome : Saudi Arabia remains in active discussions with Italy’s state-controlled shipbuilder Fincantieri over the potential acquisition of Todaro-class diesel-electric attack submarines, a move that would mark the kingdom’s first step toward establishing an undersea warfare capability.
According to a January 21, 2026 report by Tactical Report, the talks focus on submarines derived from the German-Italian Type 212A design, widely regarded as one of the most advanced non-nuclear submarine families currently in service. Saudi Arabia does not operate submarines at present, meaning any agreement would represent the creation of an entirely new naval warfare branch rather than a replacement of existing platforms.
While no contract has been finalized, the continued engagement with Fincantieri underscores Riyadh’s long-standing but cautious interest in submarines, an effort that dates back to the mid-2010s and has repeatedly stalled over cost, training, and infrastructure considerations.
A Strategic Shift for the Royal Saudi Naval Forces
The potential acquisition reflects a broader reassessment of Saudi Arabia’s maritime security requirements in the Red Sea and the Arabian Gulf. Submarines would provide capabilities that the Royal Saudi Naval Forces currently lack, including covert intelligence collection, persistent surveillance, deterrence through uncertainty, and sea-denial operations against surface combatants.
Defense analysts note that submarines are particularly well suited to operating near chokepoints and high-traffic sea lanes, where their ability to remain undetected for extended periods complicates adversary planning. In a region characterized by dense air and surface surveillance, reduced snorkeling frequency and low acoustic signatures are seen as decisive advantages.
However, officials familiar with the discussions emphasize that the challenge extends far beyond selecting a hull design. Introducing submarines would require purpose-built bases, specialized maintenance facilities, submarine rescue and safety arrangements, and years of crew training, often conducted abroad with the supplier nation.
The Todaro / Type 212A Lineage
The Todaro-class designation is commonly used to describe Italian Type 212A submarines and export-oriented concepts derived from the same design philosophy. The Type 212A originated in the mid-1990s as a joint German-Italian program to replace aging Cold War-era submarines, including Germany’s Type 206 and Italy’s Sauro-class.
Formal development began in 1996, with initial contracts signed in 1998. The first German boat, U-31, was launched in 2002 and entered service in 2005. Italian units followed from 2006 onward, with construction shared between Howaldtswerke-Deutsche Werft (HDW) and Fincantieri.
Over the past two decades, the Type 212A has served as the technological foundation for multiple derivatives, including the Type 212CD jointly developed by Germany and Norway, and the export-focused Type 214, which uses conventional steel instead of a non-magnetic hull. Elements of its design have also influenced later versions of the Type 209 family.
Construction Timelines and Industrial Realities
Production of Type 212A submarines has been incremental, rather than mass-produced. Germany ultimately planned a fleet of six boats, while Italy ordered four, with modernization and follow-on contracts extending into the early 2020s.
Each submarine typically requires five to seven years from contract signature to operational delivery. Hull construction from keel-laying to launch usually spans about three years, followed by outfitting, harbor trials, sea trials, and crew work-ups lasting another one to two years. Even with batch efficiencies, timelines rarely fall below five years per hull.
For a first-time operator such as Saudi Arabia, analysts expect additional delays before achieving initial operational capability, potentially extending the timeline to well over a decade from contract award.
Advanced Propulsion and Stealth Characteristics
The Type 212A is notable as the world’s first operational submarine class to employ air-independent propulsion (AIP) based on hydrogen fuel cells. Its Siemens proton-exchange membrane fuel-cell system generates electricity without combustion, allowing weeks of submerged operation at low speed without surfacing.
The propulsion architecture combines MTU diesel generators, large lead-acid battery banks, and the fuel-cell AIP system, enabling a maximum submerged speed of around 20 knots. When snorkeling on diesel power, the range is typically cited at 8,000 to 12,000 kilometers at economical speed.
A defining feature is the non-magnetic austenitic steel pressure hull, which reduces vulnerability to magnetic anomaly detection and influence mines. Acoustic stealth is enhanced through raft-mounted machinery, elastic isolation, a low-cavitation propeller, and anechoic hull coatings designed to absorb active sonar.
Weapons, Sensors, and Crew
The standard weapons fit centers on six 533-millimeter torpedo tubes in the bow, capable of firing heavyweight torpedoes for anti-submarine and anti-surface warfare, or deploying naval mines. Typical loadouts range from 12 to 13 weapons.
The combat system prioritizes passive detection, relying on sonar and electronic intelligence rather than active emissions. Navigation combines inertial navigation systems with GPS updates at periscope depth, while maneuvering systems are optimized for low-speed, shallow-water operations.
High automation allows operation with a crew of 25 to 35 personnel. Survivability is enhanced through compartmentalization, redundant electrical distribution, and automated damage-control systems.
Dimensions and Regional Impact
The Type 212A measures approximately 56 meters in length, with a 7-meter beam and a draught of about 6.4 meters. Surfaced displacement is around 1,450 tonnes, while submerged displacement ranges from 1,500 to 1,900 tonnes depending on configuration.
For Saudi Arabia, submarines of this class would represent a qualitative shift in naval power, enabling long-duration patrols, enhanced deterrence, and a credible undersea threat against high-value naval units operating near Saudi maritime approaches.
Despite the strategic appeal, defense officials caution that the path to a Saudi submarine force remains long and uncertain. Financial commitments, technology transfer, training pipelines, and basing decisions are still unresolved.
As talks with Fincantieri continue, the discussions highlight both Saudi Arabia’s expanding maritime ambitions and the scale of institutional transformation required to achieve them. Any eventual agreement is likely to be measured in years, not months, before Saudi crews take a submarine to sea under their own national flag.
