On 21 August 2025, at 12:32 MSK (09:32 UTC) crews of the Air and Space Forces conducted a successful launch of an Angara 1.2 launcher from the launch pad 1 of the launch complex 35 of the Plesetsk test site. (Video of the launch)

The launcher delivered into orbit four satellites, that were deployed in almost circular 319x327 km orbits with inclinations of 96.59 degrees. No Cosmos designations for the satellites has been announced. In the NORAD catalog they are registered as OBJECT A/2015-182A/65267, OBJECT B/2015-182B/65268, OBJECT C/2015-182C/65269, and OBJECT D/2015-182D/65270. If OBJECT C from the 19 June 2025 launch was designated as Cosmos-2590, these satellites would be designated as Cosmos-2591 to Cosmos-2594. [UPDATE: Yes, these are apparently the satellites' designations. They are believed to be 14F178 MKA satellites Nos. 7 to 10.]

The satellites are believed to be optical reconnaissance satellites, probably similar to Cosmos-2577 and Cosmos-2578, launched in September 2024.
