A very rare marine creature caught the attention of ship spotters. A small submarine of the C-series from the Italian shipbuilding company M23 S.r.l., which specializes in the design and construction of ultra-small submarines. In Pic 1, the third sub built for the Qatar Navy. There is almost no publicly available technical information about this specialized underwater platform. The company is a highly secretive military spin-off of the renowned Giunio Santi Engineering (GSE Trieste)
