Intense NATO Reconnaissance Activity Between the Baltic and the Black Sea

oday saw significant reconnaissance activity by NATO and allied aircraft along the Alliance’s eastern flank, with missions stretching from the Baltic Sea down to the Black Sea.

One of the most active aircraft was the USAF Boeing RC-135U “Combat Sent” (reg. 64-14847, callsign JAKE37), which took off from the United Kingdom and conducted a long mission over Poland, the Baltic States, and near the Russian border before returning westward. The Combat Sent is a highly specialized ELINT (Electronic Intelligence) platform designed to collect and analyze radar emissions, providing key insights into Russian air defense systems deployed in the Kaliningrad region and along the Baltic frontier.

Operating in the same area was a U.S. Army Bombardier ARTEMIS II (reg. N159L, callsign BRIO66), carrying out another electronic surveillance mission over Latvia and Estonia. The ARTEMIS program (“Aerial Reconnaissance and Targeting Exploitation Multi-Mission Intelligence System”) uses modified business jets for multi-mission ISR (Intelligence, Surveillance, Reconnaissance) operations.

Further south, over Romania, a Royal Air Force Boeing RC-135W “Rivet Joint” (reg. ZZ664, callsign RRR7207) was active over the Black Sea, likely monitoring Russian air and naval activity around Crimea and the Caucasus region.

The combined presence of these three platforms underscores the steady intensification of Western aerial intelligence missions along NATO’s eastern border — a sign of continued geopolitical tension related to the war in Ukraine and recent Russian military exercises in the Baltic area.
