n/a Radio Center of the Baltic Fleet (?)
Identification
The strongest match is Russian Navy/Baltic Fleet military unit 40129 in Kaliningrad. Official regional records identified v/ch 40129 as a Baltic Fleet communications node in 1999, and court materials state that from 1 December 2012 v/ch 40129 became the 742nd Guards Communications Center of the Baltic Fleet after reorganization of v/ch 95154. Labor-safety and vacancy records place the main city site at Streltskaya 10, which matches the first placemark area.

Functions
Open-source labor records at Streltskaya 10 describe 40129 as an integrated fleet communications node and also list a co-located naval-aviation communications node under the same unit number. Declared posts include secret-section staff, metrology and engineering personnel, secure-communications specialists, international secure telephone personnel, station chiefs, and signal technicians; this supports assessing the site as a multi-function fleet communications hub rather than a single-purpose radio detachment.

Dispersed sites
40129 appears to be a distributed formation. A 1997 Kaliningrad regional act listed sub-designations A, B, P, and R for v/ch 40129, consistent with multiple attached sites or detachments. Separately, a 2025 cassation ruling confirms a second restricted 40129 site near Krasnotorovka, reached by a 798 m asphalt access road used exclusively for defense and running southwest from the Romanovo–Pionersky–Salskoye–Yantarny road to the unit checkpoint.

Support footprint
The Kaliningrad city element includes substantial support infrastructure. 2020 declarations at Streltskaya 10 list warehouses for communications equipment, clothing and fuels/lubricants, guard posts, a club, feldyeger and postal staff, and technical or quality-control positions. The Kaliningrad city administration’s 2024 utilities-coordination list also gives v/ch 40129 a contact point at Ushakova 7, indicating an additional administrative or service address in the city.

Assessment
Confidence is high that the first placemark is the main Kaliningrad site of Baltic Fleet unit 40129. Confidence is moderate that the second placemark belongs to the same 40129 network, because official sources confirm a separate restricted 40129 site near Krasnotorovka on the same coastal axis, but the reviewed open sources do not publicly confirm the exact formal title radio center for that site.
