The exhibition included large scale models of the C-Series and T-Series designs.The submarine has an overall length of 23 meters (75 feet) and a width of 5 meters (16 feet). It can dive to 200 meters (650 feet) and reach speeds of 12 knots. The crew of 6 can be accompanied by a further 6 passengers, typically special forces combat swimmers. These can lock out of the submarine through a special hatch to conduct covert operations. While relatively short, its fatter beam gives it an overall size comparable to a typical 30 meter (100 foot) submarine. Comparable types, in size terms, include the Iranian Ghadir Class (actually the North Korean Yono design) and the Italian built Cos.Mo.S MG-110. The M23 design is comparatively heavily armed, with two torpedo tubes housed under the casing. These can house standard 553mm (21 inch) heavyweight torpedoes. The submarine can also carry Murena smart sea mines and launch loitering munitions.
Summary
Naval News provided coverage of submarine designs presented by M23 SRL at the DIMDEX 2026 exhibition in Doha, Qatar, held in January 2026. The showcase featured large-scale models of the C-Series and T-Series vessels, which are reportedly under construction for the Qatari Emiri Navy at a facility in Bergamo, Italy. These boats measure approximately 23 meters in length with a beam width of 5 meters, offering an overall volume comparable to standard 30-meter submarines despite their shorter hulls. Similar in size to the Iranian Ghadir Class or the Italian Cos.Mo.S MG-110, the vessels are designed to operate at depths up to 200 meters and achieve speeds of 12 knots.
The internal capacity accommodates a crew of six plus an additional six passengers, typically special forces combat swimmers who can exit via a specialized hatch for covert missions. The designs emphasize heavy armament, incorporating two torpedo tubes capable of holding standard 553mm heavyweight torpedoes. Beyond torpedoes, the submarines are equipped to carry Murena smart sea mines and launch loitering munitions. This presentation highlighted M23's capabilities in delivering compact yet potent underwater platforms tailored for specific naval requirements within the region.
