This is mostly a matter of opinion, however, I would say it would have to be the B-17 Flying Fortress.
Another OpinionThe best heavy bomber was, in my opinion, the Avro Lancaster and, by far, the best light bomber was the de Havilland Mosquito.

The Italian Campaign occurred during World War II and refers to various Allied missions that took place in and around Italy. The ultimate result was the collapse of fascist Italy.
Arthur Harris was in charge of Bomber Command.
During WWII, yes, Canada and Russia were both part of the Allied Forces.
The Avro Lancaster was the main heavy bomber of the RAF during WW2. They carried out literally thousands of missions.
Most powerful was the B29 Superfortress. For the axis powers, the Val dive bomber sank the most allied warships.
I have attached a link that has photographs of the Luftwaffe Airplanes of World War 2. They were a green/gray color but looked pretty dismal after many missions as did the bombers of the Allied Forces. Enjoy looking at the photos. You can also see them on militaryfactory com.

The Lancaster bomber, a British heavy bomber used during World War II, had a range of approximately 2,530 miles (4,070 kilometers) when equipped with a full bomb load. Its operational range could vary based on factors such as payload and mission profile, but it was designed for long-distance bombing missions, including raids deep into enemy territory.
