Around 780 deployments were made from European military bases last year in response to Russian aircraft, compared to just 410 in 2015.
Russian bomber planes approach the U.K. several times, including when Blackjack bombers spent more than five hours skirting British airspace in February.
Russian planes are not known to have violated international regulations or entered any EU nation's sovereign airspace, flying instead into "identification zones" in international airspace that are monitored for security.
A typical response sees fighter jets launched by the nearest country to visually identify the foreign aircraft and ascertain whether it is a threat, frequently flying alongside until the Russian plane breaks away and turns back.
The number of Russian planes intercepted in Eastern Europe fell slightly last year, with the Lithuanian ministry of defense saying there were 110 deployments in 2016, compared to 160 the previous year.
However, the number is still more than double that seen before the Ukrainian conflict, which has driven worsening relations between Russia and the EU over the Kremlin's military intervention and annexation of Crimea.
