North Korea has pulled upright a warship that capsized last month during a botched launch ceremony.

According to satellite imagery captured Monday, North Korean workers appear to have manually pulled the capsized Choe Hyun-class destroyer upward using tethers and balloons.

The 5,000-ton vessel capsized on May 21 during the botched launch overseen by North Korean dictator Kim Jong-un. At the time, he said the failure was an insult to the nation’s dignity and called for the arrest of those responsible.

North Korea then arrested several people involved in the launch and ordered workers to upright the ship so it could be fixed.

“To repair this, the ship will need to be moved out of the water to either a large floating drydock or graving dock once afloat,” research group 38 North wrote in a report. “However, Chongjin’s shipyard does not offer this infrastructure.”

According to the satellite photos, the ship is still partially docked at the Chongjin port. The 38 North report notes that the shipyard is mostly used for fishing and cargo vessels and was ill-equipped to launch the destroyer, which could have contributed to the accident.
