;11th Series:The 11th Series was similar to the 8th Series except it was modified as a ground attack aircraft. The conversion included adding two wing-mounted D3-40 bomb racks and six RO-82 launch rails for RS-82 or RS-132 rockets. The D3-40 bomb racks could carry bombs such as the FAB-50 or drop tanks. The racks could also be used for chemical weapon dispensers or napalm dispensers. The LaGG-3 could also be modified to use ski landing gear and when combined with external stores this caused further performance degradation.[[File:Angled vs straight.jpg|thumb|23rd Series horn-balanced [aerodynamic] vs aerodynamically unbalanced [straight] rudder.
