The Independent:
North Korea appears to be preparing for future rocket tests by developing a second submersible barge from which to launch ballistic missiles, according to new satellite imagery.
Its other test barge, which was obtained in 2014 and based at Sinpo South Shipyard, has been used to support the development of strategic submarine-launched ballistic missiles (SLBMs) and North Korea’s largest experimental ballistic missile submarine.
Satellite imagery shows the new barge has been moved to a fitting-out dock at the shipyard since previous images taken in December.
