cannons in the wings, are offset relative
to each other for spatial reasons.

NR–30 cannon in the right wing root of a Polish
Air Force Su–22UM–3K aircraft. It is worth noting
that the fuselage and wing parts were shielded
with stainless steel metal panels (picture on the
left before firing), in order to protect the surface
from the undesirable effects of exhaust gases
generated during firing (right).
