Kim Jong-un is constructing two new facilities and upgrading two that already exist for the amphibious vehicles on the country’s west coast.
It means Pyongyang’s elite forces will be just 30 minutes from the South Korean island of Daecheong-do in the West Sea.
The new bases will be at North Korea’s Yonbong-ni and satellite images taken in December show work underway on the 170-acre site, the Daily Telegraph reports.
Once completed it is thought they will be able to house up to 54 attack hovercraft, according to a study by Beyond Parallel, produced by the Center for Strategic and International Studies.
Troops would be able to land on Daecheong-do in just 30 minutes while the port of Incheon is 90 minutes away.
