The Bulgarian air force's first of 16 refurbished RSK MiG-29 fighters re-entered service on 29 November, following a successful check flight conducted at Graf Ignatievo air base.

Bulgaria's 12 single-seat MiG-29s and four two-seat trainers will have their service lives extended to 4,000 flight hours or 40 years under a $48 million refurbishment and life-extension project awarded to prime contractor RSK MiG in March 2006.

Bulgaria's Terem also assists in the work, which is performed at Graf Ignatievo. Six more aircraft will enter service by March 2008, with the remainder to follow within a further 12 months.
