Shelter Recently Dismantled at March 16 Factory

Commercial satellite imagery of North Korea’s March 16 [Truck] Factory[1] indicates that over the past eight months, a shelter has been torn down, rebuilt and then dismantled again. The exact nature of this activity is unknown, however, it is probable that it is related to the North’s ballistic missile program for several reasons:

  • All known North Korean manufactured commercial and military vehicles are capable of fitting through and undergoing their final delivery checkout using the factory’s existing building entrances and there is no obvious production requirement for a shelter for non-missile related vehicles;
  • The shelter has a unique stepped configuration with what satellite imagery suggests is a reinforced pad under its highest point—both characteristics that would be essential for testing a transporter-erector-launcher’s (TEL) or mobile-erector-launcher’s (MEL) elevation cradle and detachable launch table;
  • The temporary shelter mimics the general configuration and functions of permanent structures at the Kal-gol Missile Operating Base and 65 Factory;[2] and
  • The structure and reinforced pad were first constructed to support the preparation of the Hwasong-15 TEL used in the 2017 test.

The March 16 Factory

Located 29 km northeast of Pyongyang, in the city of Pyongsong, the March 16 Factory was established on March 16, 1977 to produce heavy trucks for both civilian and military use.[3] While long suspected of supporting the North’s ballistic missile program, it was only during late 2017 that this was confirmed by open source satellite and ground imagery.[4]

During mid-October 2017, the arrival of equipment and material for the construction of what would soon be a uniquely configured temporary shelter on the west side of the factory’s final check-out building was first observed. Subsequently, it was revealed that the building and temporary shelter were used to modify the Hwasong-15 TEL and test the operation of its elevation cradle and detachable launch table for the November 28, 2017 test launch.[5]

Following the Hwasong-15 test launch, the shelter remained essentially untouched until early 2018 when imagery from March 11 shows that the shelter’s covering was removed and the structural framework was being modified.

Figure 2. Major modifications to the shelter occurred between December 2017 and March 2018.

Imagery from April 28 shows that the framework was apparently being rebuilt. By June 30, the newly modified framework was once again covered with what appears to be canvas tarps.

Imagery from August 8 showed that the covering of the shelter had once again been removed and preparations for the complete dismantlement of the shelter had started. By September 1, the shelter and framework had been removed, but the reinforced pad is still clearly visible.

    It is likely that the March 16 Factory has been associated with the ballistic missile program for many years, however, the November 28, 2017 event provided the first readily available open source proof from ground and satellite imagery of its involvement.

  2. [2]

    The Kal-gol Missile Operating Base is one of several missile bases in the southern third of North Korea that houses what is believed to be a Scud or Scud-ER missile brigade. The No. 65 Factory is one of North Korea’s oldest and largest munitions manufacturing facilities and where it has previously modified imported WS51200 chassis into TELs.

    It is likely that it was here, at the March 16 Factory, that the Hwasong-15 TEL chassis was modified to carry and launch the Hwasong-15.
