*The Rüstsatz kits were designated by the letter "R" and a Roman numeral. Rüstsatz kits did not alter the aircraft's designation, so a Bf 109 G-6 with Rüstsatz II remained designated as 'Bf 109 G-6', and not 'G-6/R2' – the G-6/R2 was a reconnaissance fighter with MW 50, as suggested by most publications. The Umrüst-Bausatz, Umbau, or Rüstzustand were identified with either an "/R" or "/U" suffix and an Arabic number, e.g. Bf 109 G-10/U4.

Common Umrüst-Bausatz or Umbau (conversion)

U1 (Messerschmitt P6 reversible-pitch propeller to be used as air brake, only prototypes)
U2 (GM-1 boost, during 1944 several hundred converted to MW-50 boost)
U3 (Reconnaissance conversion, in autumn 1943 G-6/U3 adopted as G-8 production variant)
U4 (30 mm (1.18 in) MK 108 Motorkanone engine-mounted cannon)
