When the Squadron formed on 15 Oct 42 at Dishforth, Yorkshire, it was part of  No 4 Bomber Group, and flew Wellingtons (Well). By the time it was operational, Jan 43, No 426 was part of the Canadian No 6 Bomber Group, but was supplemented by personnel from other countries. In particular, when the change was made to the Lancaster (Lanc), most flight engineers were Royal Air Force (RAF), which carried over to the Halifax (Hal). The change to heavy bombers came with a move to Linton-On-Ouse, Yorkshire, Jun-Jul 43.
