Later production variantsThe 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 (110 lb) ETC-50 racks under the wing, along with the centerline bomb rack. The first E, 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.[9] The E models also had upgraded armour and some fuselage upgrades to support the added weight. Most pilots of the Bf 110E considered the aircraft slow and unresponsive, one former Bf 110 pilot commenting the E was "rigged and a total dog."
The Bf 110F featured the new DB 601F engines which produced 993 kW/1,350 PS (almost double the power the original Jumo engines provided), which allowed for upgraded armour, strengthening, and increased weight with no loss in performance. Three common versions of the F model existed. Pilots typically felt the Bf 110F to be the best of the 110 line, being fully aerobatic and in some respects smoother to fly than the Bf 109, though not as fast. Eventually 512 Bf 110F models were completed between December 1941 and December 1942, when production gave way to the Bf 110G.[9]
Although the Me 210 entered service in mid-1941, it was eventually withdrawn for further development. There were insufficient aircraft to fully replace the Bf 110, so it remained in service until the end of the war. In the wake of the failure of the Me 210, the Bf 110G was designed.[10] Fitted with the DB 605B engines, producing 1,085 kW (1,475 PS) in "War Emergency" setting, and 997 kW (1,355 PS) at 5.8 km (19,000 ft) altitude, the Bf 110G also underwent some changes which improved the aerodynamics of the aircraft, as well as upgrading the nose armament. No Bf 110 G-1 existed, as the Bf 110 G-2 became the baseline Bf 110G and was fitted with a large number of Rüstsätze, making the G the most versatile of the Bf 110. The initial batch of six pre-series production G-0 aircraft built in June 1942 followed by 797 G-2, 172 G-3 and 2,293 G-4 models, built between December 1942 and April 1945.[9] Pilots reported the Bf 110G to be a "mixed bag" in the air, in part due to all changes between the G and F series. However the Bf 110G was considered a superior gun platform with excellent all-around visibility, and considered, until the advent of the Heinkel He 219, the best of the Luftwaffe night fighters.
[edit] ArmamentThe Bf 110's main strength was its ability to accept some extreme weaponry. Early versions had four 7.92 mm (.312 in) MG 17 machine guns in the upper nose and two 20 mm MG FF/M cannons fitted in the lower part of the nose. Later versions replaced the MG FF/M with the more powerful 20 mm MG 151/20 cannons and many G-series aircraft, especially those who served in the bomber-destroyer role, had two 30 mm (1.18 in) MK 108 cannons fitted instead of the MG 17. The defensive armament consisted of a single, flexibly-mounted 7.92 mm (.312 in) MG 15 machine gun. Late F-series and prototype G-series were upgraded to a 7.92 mm (.312 in) MG 81 machine gun with a higher rate of fire and the G-series was equipped with the twin-barrelled MG 81Z. Many G-series night fighters were retrofitted or factory-built with the Schräge Musik (Jazz Music) off-bore gun system, firing upward at an oblique angle for shooting down bombers while passing underneath, frequently equipped with two 20 mm MG FF/M, but field installations of the 20 mm MG 151/20 or 30 mm (1.18 in) MK 108 cannons were also utilized. The Schräge Musik weapons were typically mounted to the back of the rear cockpit.
The Bf 110 G-2/R1 was also capable of accepting armament such as the Bordkanone series 37 mm (1.46 in) BK 37 cannon. A single hit from this weapon was enough to destroy any Allied bomber.
The fighter-bomber versions could carry up to 2,000 kg (4,410 lb) of bombs, depending on the type.
