=====================

Two submarines are reportedly being built for the Qatari Emiri Navy by M23 SRL in Bergamo, Italy. 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.
