A sharp-eyed satellite spotted missiles being loaded onto a Russian submarine on Friday (April 29).
A new photo captured by Maxar Technologies' WorldView-2 spacecraft shows what appear to be Kalibr missiles sitting next to a docked Kilo-class submarine in Sevastopol, an important Black Sea port in the Crimean Peninsula.
"The imagery reveals the bow section of the Kilo submarine with extended trays to load the missiles, as well as two trucks positioned nearby that are used to transport the missiles to the quay for loading onto the submarine," Maxar representatives wrote in an emailed statement.

Russia has recently attacked Ukraine with Kalibr missiles launched from submarines in the Black Sea, Maxar representatives noted in the statement.
In addition to the submarine photo, WorldView-2 also captured a broad view of Sevastopol on Friday, as well as imagery of dolphin pens at the entrance to the city's harbor. Russia is likely using trained dolphins to protect the harbor against infiltration by Ukrainian divers, NBC News reported on Thursday (April 28).
Satellites operated by Maxar and other private companies like Planet and BlackSky have been helping government officials, aid workers and the public at large monitor the ongoing Russian invasion of Ukraine, which began on Feb. 24.
Russia initially attacked broad swaths of Ukraine but recently has focused more on the southern and eastern parts of the country, after being beaten back in other regions.
Sevastopol and the rest of the Crimean Peninsula were Ukrainian territory until February 2014, when Russia invaded and annexed the region.
