The Bf 110 served with considerable initial success in the early campaigns, the Polish, Norwegian and Battle of France. During the Balkans Campaign, North African Campaign and on the Eastern Front, it rendered valuable ground support to the German Army as a potent fighter-bomber. Later in the war, it was developed into a formidable radar-equipped night fighter, becoming the major night-fighting aircraft of the Luftwaffe.
The primary weakness of the Bf 110 was its lack of agility in the air, although this could be mitigated with the correct tactics. After the Battle of Britain the Bf 110 enjoyed a successful period as an air superiority fighter and strike aircraft in other theatres, and defended Germany from strategic air attack by day against the USAAF's 8th Air Force, until a major change in American fighter tactics rendered them increasingly vulnerable to developing American air supremacy over the Reich as 1944 began.
The initial Bf 110 C-1/B fighter-bomber could carry two 250 kg, two 500 kg, or two 1,000 kg bombs on two ETC 500 racks under the fuselage and, starting with the Bf 110 E-0, could be supplemented by four additional 50 kg bombs on ETC 50 racks under the wing.
Messerschmitt omitted the internal bomb load requirement from the RLM directive to increase the armament element of the RLM specification. The Bf 110 was far superior to its rivals in providing the speed, range and firepower to meet its role requirements. By the end of 1935, the Bf 110 had evolved into an all-metal, low-wing cantilever monoplane of semi-monocoque design featuring twin vertical stabilizers and powered by two DB 600A engines. The design was also fitted with Handley-Page wing slots (actually, leading-edge slats).
The production of the Bf 110 was put on a low priority in 1941 in expectation of its replacement by the Me 210. During this time, two versions of the Bf 110 were developed, the E and F models. The E was designed as a fighter bomber (Zerstörer Jabo), able to carry four 50 kg ETC 50 racks under the wing, along with the centerline ETC 500 bomb rack. The Bf 110 E-1 was originally powered by the DB 601B engine, but shifted to the DB 601P as they became available in quantity. A total of 856 Bf 110E models were built between August 1940 and January 1942.
