Bulgaria has begun arming its air defense forces with the IRIS-T missile system, a next-generation German platform set to replace Soviet-era equipment and strengthen the country’s contribution to NATO’s collective air defense.
The country’s parliament approved the phased acquisition of one long-range and six medium-range IRIS-T systems in August 2024.
The integration announcement came during the 65th anniversary of Bulgaria’s First Air Defense Missile Base, where Chief of Defense Admiral Emil Eftimov praised the rapid progress that led to the contract’s completion.
He said the deal represents a critical step toward building a modern and NATO-compatible air defense force, according to a report by Trend.
“[Defense capability] is achieved when you acquire initial and full operational capabilities, when you are integrated into NATO’s air and missile defense system,” he said.
The rearmament program includes personnel training, construction of new infrastructure, and upgrades to Bulgaria’s radar and command systems to accommodate the IRIS-T’s digital architecture.
Base commander Colonel Tsvetelin Tsonev said the system will “significantly enhance the combat capabilities of the air defense missile units against new aerial threats” once deployed.
What the IRIS-T System Means for Bulgaria and NATO
Produced by Diehl Defence, the IRIS-T can intercept aircraft, drones, and cruise missiles at ranges up to 40 kilometers (24 miles). Its infrared-guided missile uses thrust-vectoring for agile maneuvering, making it effective against fast-moving aerial targets.
The acquisition is part of Bulgaria’s ongoing military modernization, which also includes F-16 Block 70 fighter jets and radar upgrades across the country.
It signals a shift away from aging Soviet-designed S-300 and Osa systems, replacing them with Western-standard platforms that integrate seamlessly into NATO command structures.
The system is already operational in Germany and has been exported to Ukraine, Switzerland, and Sweden to counter drones and cruise missiles.
Bulgaria’s adoption of the IRIS-T also aligns it with Germany’s European Sky Shield Initiative, a cooperative effort to build a continent-wide missile defense network.
