Referring to photographs posted on August 11 on 38 North, a US website specializing in North Korea analysis, Joseph Bermudez, a North Korea specialist, claimed that they could indicate preparations for a new test of a submarine-launched ballistic missile (SLBM).
Joseph Bermudez of 38North said the commercial satellite imagery shots suggest North Korea may be developing the 'sea-based leg of its nuclear forces'.
The pictures, which were taken in May, are said to show similar preparations to those that took place before the communist nation's last submarine launched missile test in August previous year.
The tensions between USA and North Korea escalated after Pyongyang tested an intercontinental ballistic missile in July that appears to have the range to hit major United States cities.
Mr. Bermúdez stated that the preparations around the submarine were consistent with those seen in previous trials.
The news about preparations for a submarine-launched ballistic missile test come as tensions between the United States and North Korea are escalating over the latter's vigorous efforts to gain nuclear weapons technology and successfully launching an intercontinental ballistic missile (ICBM) that theoretically could hit United States mainland cities.
The us president, Donald Trump has maintained a high level of tension Friday on the record of north korea, asserting that the military option was "ready" against Pyongyang, which has threatened to launch an attack near the american island of Guam, a military outpost of strategic of the United States in the Pacific.
