Description
In Glasic service, Sea Spear was derived from the Skybolt missile, and was designed as a medium-range defensive weapon for warships. Menghe expressed interest in the system in the mid-2010s, and in 2011 the two countries reached a joint agreement under which the Buksŏng Industries Group would produce missiles under license in Menghe.
Because the Menghean Navy already operated the YDG-7N surface-to-air missile with an active radar seeker, it was decided that Buksŏng would develop a variant of the YDG-64 equipped with an active radar homing seeker and guidance module; otherwise, the YDG-64 would be inferior to its predecessor in the number of possible simultaneous target intercepts. The seeker was directly carried over from that of the YDG-7N, but fitted in a larger-diameter nose cone to match the wider missile body. The YDG-7N's two-way datalink was also carried over, allowing the launch platform to issue continuous mid-course updates to the missile and receive targeting information from its seeker.
The YDG-64 was originally procured as a self-defense weapon for warships, particularly the Yechŏn-class frigates. It can be quadpacked into Mk 41 VLS canisters, increasing the number of missiles carried by a ship. It is also compatible with self-defense-length (4.32-meter) Mark 41 VLS cells, which appear on the Yechŏn-class frigate and other light vessels.
Because the YDG-64 uses active radar guidance, there is no practical limit on the number of surface-to-air missiles which a ship can guide simultaneously, except for the guidance limit imposed by the ship's datalink system. This makes the YDG-64 ideal for self-defense against large numbers of anti-ship missiles. In a jamming-intensive environment, the YDG-64 can also home in on targets illuminated by a STIR 1.2, STIR 2.4, or CEAMOUNT radar antenna. This limits the number of simultaneous engagements, but increases accuracy in a jamming-intensive environment and increases the probability of acquiring a target with a small radar cross-section.
With a range of 55 kilometers (30 nautical miles), the YDG-64 is only able to provide a small defensive umbrella, making it less effective than the YDG-39, YDG-60, YDG-63, or YDG-68 in the long-range air defense role but generally effective at self-defense or defense of a nearby ship.
Land systems
While Menghe did not design the YDG-64 missile itself, it was the first country to see its potential as a land-based weapon. Before sea trials with the YDG-64 were complete, the Menghean Army had already tested quadpacked YDG-64 containers on the multi-purpose 50JB2 TELAR, and design work was underway on wheeled launchers.
In the Menghean Army, the YDG-64 is mainly used as a divisional air-defense weapon, or for the protection of high-value targets such as large unit headquarters. It complements the YDG-62 at the corps level. In addition to fixed-wing aircraft and helicopters, the YDG-64 is also capable of engaging cruise missiles, guided bombs, short-range ballistic missiles, and other large air-to-ground precision-guided munitions.
In the tracked Chŏlgung air defense system, the YDG-64 is launched by the 50JB TELAR and the 50UB TEL and transloader. The 50JB carries four missile canisters and a dual-purpose E/F-band radar which can both search for targets in a chosen 120-degree sector and illuminate four targets for eight missiles. The 50UB transloader is fitted with a crane instead of a radar array, and mainly exists to resupply TEL vehicles, but it can also elevate and fire missiles at targets illuminated by another radar in the battery. Both vehicles have a crew of four, and they use the same IMCh-J Koppulso tracked chassis, to streamline supply and maintenance.
When used by the lighter Changgung air defense system, the YDG-64 is launched from a dedicated TEL which relies on a separate radar vehicle for air search and guidance. The Changgung-type YDG-64 battery has fewer missiles per launch vehicle and fewer radars per battery, but it is also less expensive and faster on roads, making it a preferable option for rear-area air defense.
All Army launchers for the YDG-64 use the same modular storage system, consisting of a standard 4-meter self-defense-length VLS canister of the same type procured for the Navy. Two steel braces are added around the canister to allow them to mount onto the launch vehicle's arm; these also allow missile canisters to be stacked and attached to one another. As with the naval VLS canisters, the YDG-64 is quadpacked, meaning that one 50UB transloader with eight canisters carries as many as 32 YDG-64 missiles.
