In order to meet at least some of the NATO requirements, in 2005 the Bulgarian government bought from Belgium a Wielingen-class frigate, the BNS Wandelaar (F-912) (built in 1977), and renamed it to the BG Drazki. In 2005, Bulgarian ship Smeli for first time took part as full NATO member in NATO OAE (Operation Active Endaevour). In 2006, following a decision of the Bulgarian Parliament, Drazki took part in the United Nations Interim Forces in Lebanon (UNIFIL), patrolling the territorial waters of Lebanon under German command. This was the first time ever the Bulgarian Navy took part in an international peacekeeping operation. The Bulgarian government purchased two Wielingen-class frigates and one Tripartite minehunter in 2007.
