The Savoia-Marchetti SM.92 was an Italian prototype heavy fighter/bomber aircraft developed during the Second World War. Based on the previous SM.88 prototype heavy fighter, the aircraft featured a dual-boom design with two engines and two crew members both in a single cockpit. Like it’s predecessor, only a single prototype was built; this aircraft was tested but later damaged when an Axis fighter pilot mistook it for the similarly-shaped American P-38 Lightning. After being grounded for repairs, the single aircraft was destroyed by Allied bombing, thus ending the life of this unique Italian heavy fighter.

In 1939, the Italian aircraft firm Savoia-Marchetti produced the SM.88 fighter - this was a prototype heavy fighter aircraft with twin booms, two engines and a crew nacelle nestled in between the booms. Despite being quite successful in tests, the project was abandoned due to the introduction of the German Bf 110, a heavy fighter with similar performance.

The SM.92 was developed at the same time as the earlier [[SM.91]] heavy fighter, enabling the use of common components for both aircraft. The aircraft featured a twin boom design, meaning that there were two separate fuselages on the aircraft, one on each side. For simplicity, the SM.92 utilized the fuselage booms, tailplane and wing structure of the SM.91. However, the aircraft had just a single cockpit mounted asymmetrically on the portside or left fuselage. The two crew members consisted of a pilot and dedicated rear gunner, who operated the remote controlled turret at the rear.

The SM.92 was powered by two Daimler-Benz DB 605 engines producing a combined 2580 hp - fitted to the front of each boom, the engines drove three-bladed propellers. This powerplant enabled the SM.92 to reach a maximum speed of 630 km/h at altitude, with a service ceiling of 12 km. The armament consisted of three MG 151/20 cannons mounted on the centreline and inside the starboard propeller hub, as well as four Breda-SAFAT machine guns mounted firing forwards. A single additional Breda-SAFAT gun was mounted firing rearwards in the tailcone, though this weapon had a very narrow defensive arc.

In March of 1944, the prototype was airborne when it was engaged by an axis pilot, flying a Macchi [[C.205 (Family)|C.205]], who had mistook the aircraft for the Allied [[P-38 (Family)|P-38 Lightning]]. Having taken severe damage, the aircraft limped home and was grounded for repairs; it was in this state that the aircraft was destroyed by Allied bombing, ending the development of this interesting aircraft design.

Description

The SM.92 is a rank III Italian attacker with a battle rating of 4.0 (AB/RB) and 4.3 (SB). It was introduced in Update 1.87 "Locked On".

The SM.92 is an Italian twin-engine fighter/bomber prototype designed and produced in 1943. It utilized two imported German Daimler-Benz 605 engines. It was designed to have better performance than its predecessor, the SM.91. The middle gondola was eliminated and the cockpit for the crew of two, the pilot and the gunner, was moved behind the left engine. The gunner remotely operated a fixed 12.7 mm Breda-SAFAT machine gun located in the aircraft's tail.

The SM.92 had an armament complement of three 20 mm MG 151 autocannons and four 12.7 mm Breda-SAFAT machine guns.

In-game this plane can reach over 16 m/s in climb rate and with its air spawn, that is enough to get a sufficient altitude above most fighters once the engagements start.

The SM.92 has a better performance than its predecessor, despite the engines staying the same. It has been made much more aerodynamic with the removal of the gondola on the SM.91 and the moving of the crew to the left fuselage, behind one of the 2 powerful Daimler-Benz 605A1 engines. Part of this improvement is also due to the change on the defensive armament, changing from a 20 mm cannon with a decent traverse to an aerodynamically mounted fixed 12.7 mm Breda-Safat

This plane also has leading edge slats, which help it on its roll rate (as they get deployed on one wing when doing a roll manoeuvre) and its low speed performance.

Usage in battles

Describe the tactics of playing in the aircraft, the features of using aircraft in a team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view, but instead, give the reader food for thought. Examine the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).

Pros and cons

Pros:

  • Lots of guns that can be brought to use

Cons:

  • Defensive turret is almost fixed (only ±2° in each direction); the target has to be at exact 6 o'clock to be engaged
  • Bad rate of acceleration even when diving
