The Daedam class are the newest class of nuclear-powered guided missile submaries designed by Bangwigwan (formerly Institute 72) and built at the Musan Submarine Plant for the Menghean Navy. They are the largest submarines under construction anywhere in Septentrion, and they are currently in high-rate production, with two vessels entering service every year.
Daedam-class submarines are designed to locate and engage enemy high-value surface targets, including aircraft carriers, amphibious assault ships, and trans-oceanic supply convoys. For this role, they carry a heavy battery of 84 YDH-28 anti-ship missiles which can be launched from underwater to overwhelm large escort formations. They also have relatively generous crew accommodations, to support long-range patrols and prolonged shadowing of potential targets in peacetime.

Crew accommodations
In contrast to the Chungsŏng class boats, which were reportedly cramped and uncomfortable, the Daedam-class submarines have relatively generous crew accommodations. A Menghean state news report touring the lead boat showed a large mess hall, an exercise room, a briefing room, and a well-decorated lounge which includes a library with books and electronics. Menghean news reports have also referred to a "tea room" aboard the submarines, though this apparently refers to the officers' lounge rather than a dedicated tea space. Footage from the tour also showed wood paneling, or paneling in a fireproof wood substitute, in many crew areas.
Foreign intelligence agencies have also noted that the crew count for the Daedam-class submarines is relatively large compared to previous Menghean and similar Letnian submarine classes. While some of this increase stems from the submarine's large size, it is also consistent with an effort to reduce each crew member's workload and conduct more maintenance at sea. Combined with the improved accommodations, these changes suggest that the Daedam-class submarines are intended to conduct longer patrols further from friendly ports and bases.
