- Rember that the Spitfire and the ME109 had both tried putting cannon
- in the wings earlier in the wear. However to maintain muzzle velocity,
- you have to keep barrel length. These guns would not fit into the
- wings properly (actually, the Germans had to conduct another design
- shange to the wing of the 109 which decreased its performance) so the
- barrells were trimmed. Another problem is the weight of ammunition
- which can be carried. Usually giving less firing time.
