The YDG-62 (Menghean: 유도탄,대공 Yudotan, Daegong "Missile, Anti-Air") is an advanced medium-range surface-to-surface missile designed and produced in the Socialist Republic of Menghe. It serves with the Army and Navy, and shares the same basic design and designation in both branches. It has also been exported to some other members of the Namhae Front, including Ummayah.

With a range of 55 kilometers in its base variant, and 80 kilometers in the "B" variant that entered service in 2013, the YDG-62 missile is generally considered a medium-range weapon for its time period. In Menghean Army units, it serves the Air Defense Brigade at the Corps level, in between the YDG-60 at the Army level and the YDG-65 in each Division. In the Navy it can be used in area defense of carrier-battlegroups and long-range self-defense for major warships. The missile is designed to engage aircraft, cruise missiles, anti-ship missiles, and mid-to-large-size UAVs, as well as certain short-range ballistic missiles in the mid-flight or terminal phase.

Naval system

The YDG-62 was originally developed at the request of the Menghean Navy, to equip its new Haeju-class destroyers. It was designed to be launched from 6.2-meter-deep VLS cells, a requirement which influenced its length and gave it its vertical booster stage. When used in combination with the HYR-38 or HYR-72 radar illuminators, it forms the "Jangbyŏng" air-defense suite. This system is also installed on the second series of Jŏngdŏk-class frigate.

Land systems

JYDG-62

The first self-propelled Army variant of the YDG-62 entered service in 2006, and is displayed at the top of the page. The full battery system is designated JYDG-62, with the "J" prefix indicating "self-propelled type" (자주식, Jajusik). All components of the system are distinguished from one another by designation suffixes, such as JYDG-62BGR (Balsagi/Radar, "launcher/radar") for the TELAR unit.

The TELAR itself incorporates a multi-purpose radar array, which can be used to autonomously scan the sky or designate individual targets for missiles. On the base variant of the vehicle, it is capable of designating separate targets for four missiles at once. The TELAR also carries four YDG-62 missiles in enclosed rectangular cells, which protect the missile from environmental damage until it is launched and allow for easy reloading. The transporter-loader vehicle, JYDG-62JCh, carries an additional four missile boxes and a loading crane, and it shares the ability to elevate its missile cells and fire, though it must rely on a nearby TELAR to illuminate the target. The loader vehicle also has a bulldozer blade in front, which it can use to clear obstacles, construct a firing position, or stabilize the hull while the forward-mounted crane is in use.

An unusual feature of the JYDG-62BGR is that the missile cells do not rotate with the radar array, but instead the radar rotates in front of them, meaning that the radar can only illuminate targets in a roughly 270-degree forward arc. In order to compensate for this feature, it is standard practice for battery commanders to deploy their launchers in an outward-facing circle, so that the individual launchers can cover each other's blind spots.

All vehicles in the JYDG-62 system use the same universal heavy chassis as the JJP-152/48 self-propelled gun, which gives it very good offroad mobility compared to a wheeled chassis. The upper hull is also well-armored against shrapnel, in the hopes that even if an anti-radiation missile strikes the radar unit and detonates above, the crew will still survive the blast and can drive back to a safe point and mount another vehicle. The battery components are outlined below:

  • 1x JYDG-62JS (Jungdae Salyŏngcha), Company/battery command vehicle with radio and wire connections. Crew of six.
  • 3x JYDG-62BG (Balsagi/Radar), TELAR with four missile boxes and a radar array. Crew of four.
  • 3x JYDG-62BJCh (Balsagi/Jaejangjŏn-Cha), TEL and reload vehicle with four missile boxes and a crane. Crew of three.

The Air Defense Battalion also includes the tracked JSR-442 air search radar, which has a greater range and detection power than the radar sets on individual TELARs, and missile transporter trucks that carry four missile cells each but rely on the TEL cranes for loading.

GYDG-62

This system, distinguished by the prefix Gyŏng (경/輕), is a lightweight wheeled counterpart to the JYDG-62 system described above. All vehicles in the battalion use the Taekchŏn T212 8x8 wheeled truck chassis, which has a faster road speed and greater fuel efficiency, giving it greater strategic mobility. This system is more common in the Army's Coastal Defense Forces, which have to patrol a large area of domestic coastline but benefit from good road infrastructure.

The structure of the GYDG-62 system is different from its tracked counterpart, and more closely resembles the self-propelled system for the YDG-60 SAM. The launch vehicles are TELs rather than TELARs, and rely on a separate battery-level radar vehicle to search for and illuminate targets. The GYDG-62 launcher and loader vehicles also carry their missiles in a 2x2 rather than 1x4 arrangement.
