Mysterious white balloons seen near North Korea's 5,000 ton sunken warship, what are they?

Following a failed launch that left North Korea's advanced warship partially submerged, satellite images reveal balloon-like structures deployed around the wreckage. Experts speculate these balloons aim to prevent further flooding, shield the vessel from surveillance, or relieve hull pressure. Salvage operations are complicated by the ship's precarious position, potentially requiring dismantling.
