The Asella Argonti-class was a class of two large cruiser submarines built for the Cacertian Royal Navy in the early 1900s and were known as some of the largest submarines built at the time. Originally envisioned as a line of ocean-going submarines built for raiding, only two ships of the intended sixteen were ever completed and put to sea. Their high build cost, slow-speed, subpar surface armament, and significant noise were all factors in their eventual cancellation.

Both the HMS Asella Argonti and HMS Fortunata Carfagno were deployed to Syara during the Divide War as raiders which directly attacked naval bases and shipyards of the Republic. Their effect on the war was relatively minor and the Fortunata Carfagno was ultimately captured by Syaran forces after it was unable to submerge after receiving fire from a coastal battery. She was later renamed to Destitute Pilgrim and pressed into service with the Navy of the Syaran Republic.

The Asella Argonti was removed from active duty after the Divide War and utilized as a vessel for gun crew training before ultimately being scrapped during the Siduri War in 1936. Her gun barrels, which were incompatible with other Cacertian ships of the era, are the only relics that remain of the ship and are on display at the Fumicino Naval Warfare Museum.
