== Introduction ==

The Douglas A-20 Havoc was a versatile American attack aircraft that played a significant role during [[World War II]]. Known for its adaptability and robust performance, the A-20 was employed in various roles, including light bomber, night fighter, and reconnaissance missions. This article delves into the technical specifications, operational history, and variants of the Douglas A-20 Havoc, providing a comprehensive understanding of its contributions to military aviation.

== Development and Design ==

The development of the A-20 Havoc began in the late 1930s, as the [[Douglas Aircraft Company]] sought to create a new light bomber that could meet the requirements of the United States Army Air Corps. The initial design, designated as the DB-7, was a twin-engine aircraft featuring a mid-mounted wing and a tricycle landing gear, which was innovative for its time.

The A-20 was powered by two [[Wright R-2600 Twin Cyclone]] radial engines, each capable of producing 1,600 horsepower. This powerplant provided the aircraft with a top speed of approximately 317 mph (510 km/h) and a range of 1,025 miles (1,650 km). The aircraft's armament typically included four forward-firing .50 caliber machine guns and a bomb load of up to 4,000 pounds (1,800 kg).

== Operational History ==

The A-20 Havoc first entered service with the [[Royal Air Force]] (RAF) in 1940, under the Lend-Lease program. The RAF utilized the aircraft in a variety of roles, including night fighting and intruder missions, where it was known as the Boston. The aircraft's versatility and performance quickly gained recognition, leading to its adoption by several Allied air forces.

In the [[United States Army Air Forces]] (USAAF), the A-20 was primarily used in the Pacific Theater, where its speed and maneuverability proved advantageous in low-level bombing and strafing missions against Japanese forces. The aircraft also saw extensive service in the European Theater, supporting ground operations and disrupting enemy supply lines.

The Soviet Union was another major operator of the A-20, receiving over 3,000 units through the Lend-Lease program. The aircraft was highly valued by Soviet pilots for its reliability and effectiveness in ground-attack missions, contributing significantly to the Eastern Front's air campaigns.

== Variants ==

The Douglas A-20 Havoc was produced in several variants, each tailored to specific operational requirements:

* **A-20A**: The initial production version, featuring R-2600-3 engines and a crew of three. It was primarily used for training and reconnaissance missions.

* **A-20B**: An improved version with a redesigned nose and increased fuel capacity. It was used by the USAAF and the Soviet Air Force.

* **A-20C**: Equipped with self-sealing fuel tanks and additional armor, this variant was designed for combat operations. It was widely used by the RAF and the USAAF.

* **A-20G**: The most produced variant, featuring a solid nose with six .50 caliber machine guns. It was primarily used for ground-attack missions.

* **P-70**: A night fighter variant equipped with radar and additional armament. It was used by the USAAF for night interception missions.
