Why point the whole plane at the target. Why not moveable forward guns?

Weights !!!

An heavier plane will move slower and be less agile and manoeuvrable. What the point of having a movable gun in front if you can't pursue your opponents or can't climb with him ?

Defiants although looking sexy on paper were sitting ducks for the 109.

It has even some difficulty catching with bombers.

So the nice and curved shape of the turret was of no use just as a nice and busty silhouette on a ring of a heavy weight championship.
