Stoyanov said the Spanish Eurofighter jets were expected to land in Bulgaria on November 1 and will perform airspace protection duties along with the Bulgarian Air Force until December 23.
"This is yet another mission on enhanced air policing. It will be a joint airspace security duty, " Stoyanov told reporters.
Spain and the Netherlands took part in similar air policing missions in the Black Sea country earlier this year.
Bulgaria, a NATO member since 2004, is hosting a NATO battlegroup of up to 1,000 troops under Italian command as the alliance seeks to bolster its eastern flank.
