The Yunlong-class submarine is a series of Monsilvan diesel-electric attack submarines. The first boat in the class entered service with the Monsilvan Navy in 2009. The design is an evolution of the Hsiayan-class submarines, from which it can most easily be distinguished by its X-shaped stern combination diving planes and rudders. The Yunlongs have the largest displacement of any submarine used by the Monsilvan navy.
It is one of Monsilva's first air-indpendent propulsion submarines. From Yunlong to Doulong, all Yunlong-class submarines are fitted with Soong V4 engines, allowing them to stay submerged for longer periods of time. Furthermore, in the Monsilvan Navy, SKC Fenglong is one of the first lithium-ion battery submarines. The cost of the third submarine in the Monsilvan Navy (SKC Heilong) was estimated at ¥3.26 billion (₵540 million).
The successor to the Yunlongs, the Dajing-class submarines, entered the planning and production phase in 2019.

Variants
The sixth Yunlong-class submarine (SKC Fenglong) is the first Monsilvan submarine in the fleet to mount lithium-ion batteries.
Lithium-ion batteries have almost double the electric storage capacity of traditional lead-acid batteries, and by not only replacing them in the existing battery storage areas but adding to the already large battery capacity by also filling the huge space (several hundred tons displacement) inside the hull previously occupied by the older engines and their fuel tanks with these new batteries, the amount of (more powerful) batteries carried overall is massive. This has improved the underwater endurance significantly and is felt will be an advantage over the slow recharge capability of the AIP system.
In any event, the Monsilvan Navy believes that lithium-ion is the way forward and intends to 'trial' this new system and compare it to the previous systems for operational effectiveness.
Exports
Soong Shipbuilding Corporation, on behalf of Monsilva, exported 5 Yunlong-class submarines to Kivu in the early 2010s. They have been commissioned to the Kivuian Navy.
