History

The Type 142 demonstrated such exceptional performance that the Air Ministry immediately ordered a bomber derivative, which became the Blenheim. The Mk I entered RAF service in 1937 and was widely exported, serving with Finland, Romania, Turkey and Yugoslavia. By the outbreak of war it was already becoming obsolescent but flew the first RAF bombing mission of the Second World War on 4 September 1939.

Variants

The Blenheim I was the initial short-nosed bomber variant; the Mk IV introduced a lengthened nose and greater range; the Mk IF was a long-range fighter version with a ventral gun pack.

Where you'll see it

Blenheim Is served in the Middle East and Far East after being replaced in Europe, with Finnish Blenheims remaining operational into 1944 against Soviet forces.
