The Heinkel He.111 was a German monoplane medium bomber (also torpedo bomber and attack bomber). The He.111H-16 was the third standard H-series variant, the other two being H-3 and H-6. Most other variants were generally used in very specialised roles. Specifically, the H-16 was a further development of the H-6 with Jumo 211 F-2 engines, although several other interim variants also introduced minor changes based on combat experience. Defensive armament remained the same as on the H-11.
Many different loadouts were supported; the bomb bay was retained and could also be used for extra fuel tanks. In the latter case, under-fuselage ETC 2000 bomb rack was used. The H-16 was supplied with several armament kits, including the R-1 with a 13mm MG 131 in a dorsal turret, the R-2, a glider tug and the R-3, with improved armour at the cost of a lighter bomb carrying capacity.
