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.

There is also a small floating crane moored alongside the barge, with its boom extended over the vessel.
The purpose of the work is unclear. It probably concerns final stages of repair before the barge is declared operational, Joseph S Bermudez Jr, an analyst at 38 North said.
He said it was unclear when the barge would become operational.

But the South Korean president, Moon Jae-in, has praised Donald Trump for his belligerent approach to diplomacy with North Korea, saying last week that “President Trump deserves big credit” for helping bring about new inter-Korean talks.
