Bulgaria will give Ukraine faulty missiles that it cannot repair itself
Instead, Ukraine has the technical capabilities to do so, the government explained

At an extraordinary meeting, the Defense Committee of the Bulgarian National Assembly adopted a proposal that Bulgaria send to Ukraine defective 5B55R(K) anti-aircraft guided missiles and ammunition for 5.56x45 mm automatic small arms that are no longer needed by the Ministry of Internal Affairs.

At the meeting, an expert from the Ministry of Defense explained that these missiles have not been tested and Bulgaria has no way to repair them.
"In Bulgaria, we do not have the ability to repair missiles of this type, but Ukraine does. This is done in conditions that we do not have," commented Defense Minister Todor Tagarev.
The provision of faulty missiles to Ukraine will in no way impair the capabilities of the Bulgarian army. Experts claim that they cannot be repaired in Bulgaria, Defense Minister Tagarev assured.
According to Hristo Gadev of the GERB-SDS, chairman of the defense commission, the assistance provided to Ukraine has not yet impaired the combat capability of the Bulgarian army.
As a reminder, on August 3, the Bulgarian government approved a draft agreement between the Bulgarian Ministry of Internal Affairs and the Ministry of Defense of Ukraine on the free provision of armored vehicles. This is military assistance in the form of about 100 Soviet-style armored personnel carriers. The APCs have been in the possession of the Bulgarian Ministry of Internal Affairs since the 1980s.
