Poznámka:
Note:
- Fighter-bomber version of Yak-9D (factory designation Yak-9L) Difficult to hook bombs and very poor handling with a full bomb and fuel load. And inadequate bomb sight and lack of special aiming equipment limited combat usefulness.

- I'll add one more little thing, the bombs were in the bomb bay, which was just behind the pilot's seat. They were suspended with the tip up, vertically. Hanging the bombs was quite complicated, the rear part had to be raised about 0.5 m and the FAB-100 bombs were pulled into their "tubes" by a pulley that was in place of the dismantled rear part of the cabin. This operation took 20-30 minutes. After settling, they reached the "bottom of the tubes" and the top was fixed with intermediate rings.
- Aiming was done using lines on the fuselage in front of the cabin and on the wings, depending on the angle of flight and the speed of the aircraft.
- In practice, two FAB-100 bombs were most often used, with four the aircraft was overloaded and unstable, but use was possible.
- The PTAB anti-tank mines were in containers and in this case were dropped in sets of 32.
