Developed from IMAM Ro.57

The IMAM Ro.58 was an Italian twin-engined, two-seat monoplane heavy fighter and attack aircraft, a development of the IMAM Ro.57. First flown in May 1942, it was considered a general improvement over its predecessor, mainly due to the substitution of higher power Daimler-Benz DB 601 engines for the Fiat A.74 engines used on the Ro.57. Initially it had many problems and during the maiden flight only the proficiency of the test pilot, Adriano Mantelli, saved the plane. [1]

It was easily recognizable because it appeared to have a long hump over the fuselage (to accommodate two crew members as opposed to one in the Ro.57). The Ro.58 was a twin-tailed aircraft, in layout similar to the Bf 110.

The performance of the aircraft with the DB 601 engines was much better than even many single engine fighters of the time (605 km/h at 5,000 m, 1,500 km endurance, 10,500 m ceiling).

More heavily armed than its predecessor, with five forward-firing MG 151s; three in the nose and two under the belly (the underbelly guns were not present during the first flight tests) and one 12.7 mm rear-facing Breda-SAFAT machine gun.

Tested alongside an Me 410 it was found to be superior, [1] but even so it initially had its share of problems that delayed production. By the time it was refined it was too late for Italy, and there were no resources even for single-engine fighters, much less the more expensive twin-engined ones.

As with the Ro.57, which was not put into production in 1940 or 1941, the Ro.58, better armed and faster appeared only in May 1942, and too late to be produced in any numbers, as Italy surrendered to the Allies in September 1943.

The Macchi C.205Veltro was an Italian World War II fighter aircraft built by the Aeronautica Macchi. Along with the Reggiane Re.2005 and Fiat G.55, the Macchi C.205 was one of the three "Serie 5" Italian fighters built around the powerful Daimler-Benz DB 605 engine. The C.205 was a development of the earlier C.202 Folgore. With a top speed of some 640 km/h (400 mph) and equipped with a pair of 20 mm cannon as well as 12.7 mm Breda machine guns, the Macchi C.205 Veltro was highly respected by Allied and Axis pilots alike. Widely regarded as one of the best Italian aircraft of World War II, it proved to be extremely effective, destroying a large number of Allied bombers. The Macchi C. 205 proved capable of meeting fighters such as the North American P-51D Mustang on equal terms, which encouraged the Luftwaffe to use a number of these aircraft to equip one Gruppe.

<span class="mw-page-title-main">Messerschmitt Bf 110</span> 1936 heavy fighter family by Messerschmitt

The Messerschmitt Bf 110, often known unofficially as the Me 110, is a twin-engine Zerstörer, fighter-bomber, and night fighter (Nachtjäger) developed in Nazi Germany in the 1930s and used by the Luftwaffe during World War II. Hermann Göring was a proponent of the Bf 110, believing its heavy armament, speed, and range would make the Bf 110 the Luftwaffe’s premier offensive fighter. Early variants were armed with two MG FF 20 mm cannon, four 7.92 mm MG 17 machine guns, and one 7.92 mm MG 15 machine gun for defence. Development work on an improved type to replace the Bf 110 - the Messerschmitt Me 210 - began before the war started, but its teething troubles resulted in the Bf 110 soldiering on until the end of the war in various roles. Its intended replacements, the aforementioned Me 210 and the significantly improved Me 410 Hornisse, never fully replaced the Bf 110.

The Focke-Wulf Fw 191 was a prototype German bomber of World War II, as the Focke-Wulf firm's entry for the Bomber B advanced medium bomber design competition. Two versions were intended to be produced, a twin-engine version using the Junkers Jumo 222 engine and a four-engine variant which was to have used the smaller Daimler-Benz DB 605 engine. The project was eventually abandoned due to technical difficulties with the engines.

The Fiat G.55 Centauro was a single-engine single-seat World War II fighter aircraft used by the Regia Aeronautica and the Aeronautica Nazionale Repubblicana in 1943–1945. It was designed and built in Turin by Fiat. The Fiat G.55 was arguably the best type produced in Italy during World War II, but it did not enter production until 1943, when, after comparative tests against the Messerschmitt Bf 109G and the Focke-Wulf 190, the Luftwaffe itself regarded the Fiat G.55 as "the best Axis fighter".

Breda-SAFAT was an Italian weapons manufacturer of the 1930s and 1940s that designed and produced a range of machine-guns and cannon primarily for use in aircraft. Based on the M1919 Browning machine gun, the Italian guns were chambered to fire indigenous ammunition with 7.7 mm (0.303 in) and 12.7 mm (0.500 in) calibres, predominantly ball, tracer for the 7.7mm, including high explosive incendiary tracer (HEI-T), or armour-piercing (AP) for the 12.7mm.

The Messerschmitt Me 265 was a design project for a Zerstörer, produced by leading German aircraft manufacturer Messerschmitt in World War II.
