abstract:Heavy bombers are bomber aircraft with the greatest bomb load carrying capacity and longest range of their era. The most recent definition comes from the New START, agreement between the USA and the Russian Federation, signed in Prague on April 8, 2010, relating to nuclear bombers.
On 26 August 1940, a large German bomber force, with heavy fighter escort, was heading towards targets in England including the RAF fighter stations at Biggin Hill and Kenley.
