• A video shows bombs being dropped on what appears to be a Russian military camp in Bakhmut.

• The JDAM-ER kits have been sent to Ukraine from the US in recent months.

• The kits turn unguided free-fall bombs into all-weather, precision-guided smart weapons.

A video appears to show Ukraine attacking a Russian military camp in Bakhmut using US-made JDAM-ER technology.

The bomb kits, which turn unguided free-fall bombs into precision-guided munitions, have reportedly been sent to Ukraine in recent months.

The video was shared on social media by the Army of Drones, a crowdfunding initiative part of Ukraine’s government platform United24, which claims to have raised $108 million and bought 3,300 drones for the army, according to Forbes.

Aerial video shows four bombs hitting buildings the drone army said were Russian warehouses in Bakhmut, eastern Ukraine, where fierce fighting has been raging for months.

The Twitter account ukraine gun tracker, who monitored videos and images of weapons used in the conflict, said the bombs appeared to be GBU-62, which describes Mk 64 Quickstrike naval mines in combination with the extended-range Joint Direct Attack Munition kits.

The kits can be bolted to unguided bombs from 500 to 2,000 pounds, and their folding wings allow them to glide for up to 45 miles.

According to the report, this appears to be one of the first videos showing JDAM-ER-equipped bombs in action in Ukraine.

Mark Cancian, a senior advisor at the Center for Strategic and International Studies, told Newsweek that the building could have been used as a sort of Russian headquarters.

“The explosion is large and seemingly precise, indicating air-delivered munitions,” Cancian said. “Apparently the US sent the extended-range version of JDAM. That would mean that the Ukrainian plane wouldn’t have to overfly the target.”

Leaked Pentagon documents have previously revealed concerns that the bomb sets were hampered by Russian signal jamming.

The documents were among sensitive intelligence documents recently leaked on the internet and are now the subject of a federal investigation.
