The two RAF planes, which are currently policing the Baltic skies, were alerted after the Russian Ilyushin IL-20 Coot surveillance aircraft was spotted.
The Ministry of Defence (MoD) said the incident took place in international airspace over the Gulf of Finland at lunchtime.
Nato has been policing the skies over the Baltic states since 2004 when Estonia, Latvia and Lithuania joined the alliance.
Missions were stepped up following Russia’s aggression against Ukraine, which has led to other Baltic states feeling increasingly threatened.
Last month, HMS Argyll was deployed to monitor a destroyer and two other ships from Russia as they passed through the English Channel, while Typhoons were sent from RAF Lossiemouth in Scotland after two Russian Bear aircraft were spotted flying near to UK airspace.
