Mystery 'balloons' swarm stricken North Korean warship

has deployed what appear to be balloons alongside its damaged 5000-ton warship that has been laying on its side and partially submerged since a botched launch last week.
While the purpose of the objects is unclear, experts told
CNN
they could be used to help get the ship back upright, or protect it from the prying eyes of drones.
The stricken destroyer was the country's newest warship and was meant to be a triumph of North Korea's ambitious naval modernisation effort.

reported, in a rare admission of bad news.
North Korean leader Kim Jong Un, who witnessed the failed launch in the north-eastern city of Chongjin, called it a "criminal act" and ordered the country to swiftly repair the as-yet-unnamed ship before the late-June plenary session of the ruling Workers' Party, calling it a matter of national honour.
Officials have since scrambled to undo the damage and punish those they claim are responsible, detaining four people in recent days, including the shipyard's chief engineer.

Analysts say it appears balloons are being used in North Korea's effort to swiftly repair the destroyer.
"It looks like what appear to be balloons have been installed not to refloat the ship, but to prevent the ship from further flooding," said Representative Yu Yong-weon, a South Korean National Assembly lawmaker and military analyst.
Retired United States Navy Captain Carl Schuster said if the objects are indeed balloons, they could have one of two purposes – either to prevent "low- to mid-level drone reconnaissance," or to reduce the stress on the part of the ship still stranded on the pier.

"That is the area that is most likely to have been damaged, suffered the most severe damage and remains under intense stress while the forward area remains out of the water," he said.
Nick Childs, senior fellow for naval forces and maritime security at the International Institute for Strategic Studies, said North Korea could be in danger of further damaging the ship if it's using balloons to keep it afloat or raise it.
"It is highly likely that the ship is under quite a lot of stress anyway," and lifting from above could compound those stresses, he said.

Normal procedure would be to get as much buoyancy as possible in the ship and then raise it from below, Childs said.
According to satellite images shared by Maxar Technologies, more than a dozen white, balloon-like objects have been deployed around the destroyer since May 23.
Based on the objects' shape and what appear to be tail fins, they could be smaller versions of what are known as aerostat aircraft, balloons with a slight resemblance to dirigibles, defense experts told
CNN
. Like blimps, dirigibles get buoyancy from a lifting gas that allows them to float in air or in water.

The images don't appear to show any flotation bladders supporting the hull or the body of the ship, Schuster said – something the US might use in such a situation. He added that North Korea's maritime industry might not be advanced enough for such techniques.
North Korean state media had previously reported that the damage was less severe than initially feared, and that there were no holes in the hull, though it was scratched along the side and some seawater had entered the stern. It estimated repairs could take about 10 days – though analysts are skeptical.
Schuster had previously told
CNN
that repair work could take up to six months, depending on how far the hull damage extends, how much water entered the warship, and how much "salt crust" might have formed on metal surfaces such as joints.
The ship's precarious position also makes the salvage operation unusually complex. "Having it half in and half out of the water is basically the worst possible situation," said Decker Eveleth, an associate research analyst at CNA, a nonprofit specialising in defense research.
He added that the operation would be simpler if the ship had fully capsized into the water, or if it had fallen over entirely on land. "But as it's half on land and half on water – if you try to pull the sunken half out, you're risking twisting and breaking the keel," Eveleth said, referring to the structural spine running along the ship's bottom. "And if you do that, the whole ship is junk."
Childs said North Korea may have to cut the ship into pieces and then try to salvage what it can because righting it from its current position is an extremely complex task.
"Very often the only way you clear the dock … is to dismantle at least part of the ship to make the operation easier, right what you have left and tow it away and make a decision on whether you rebuild it or scrap it," he said.
