The Korean People's Army (KPA) Air Force Command said an RC-135 plane had flown over territorial waters on 6, 8 and 10 June .Background on EC-121 shootdown here. Now, if they threaten to capture a US spy ship, history will be repeating itself.
In a statement it said the US flights were "openly crying out for a pre-emptive attack" on the country.
The command said the espionage missions were a "violent infringement of [North Korea's] sovereignty and a grave violation of international law".
It continued: "The KPA Air Force seriously warns the US imperialists that it will sternly punish the aggressors if their planes continue illegally intruding into the sky ... on espionage missions.
"They had better not forget the wretched fate of the EC-121 large spy plane in the 1960s," it added.
