Avro submitted their modified C105 design in May 1953, essentially a two-man version of the C104/2.A change to a "shoulder-mounted" wing allowed rapid access to the aircraft's internals, weapons bay, and engines.The new design also allowed the wing to be built as a single structure sitting on the upper fuselage, simplifying construction and improving strength.
