Just leaves Soyuz-FG 013 which must be getting close to the end of its storage life. Soyuz-U has a guaranteed period of storage of 6 years and 5 months.
I'm thinking about 3 options:
1. produced (stored, waiting to launch)
2. non-produced (13 - unlucky number)
3. during production (013) redesignated to 023 (unlikely).
