SMX-25 (the informal name of a diving frigate) is a 21st-century gun-ship being developed by the French ship building company, DCNS. It is a hybrid between a surface ship and a submarine.

It is 110 metres long and displaces 3000 tons. The submerged body is an elongated knife-like form, optimized for high speed when moving on the surface. Its main feature is the ability to quickly travel to distant places and then strike from under water. SMX-25 is to be armed with 16 multi-function missiles, capable of striking submarine and surface targets with four torpedo tubes. The ship, which looks like a spindle with a massive superstructure, will be automated. One version of the ship will implement stealth technology to enable it to carry out reconnaissance and insert sabotage groups of up to spec-ops.
