Avia B-228 / CB-228

1st Flight 1946
The Avia B-228 ia a licensed copy of the Ilyushin Il-28.
AVIA B-228
The aircraft is conventional in layout, with high, un swept wings carrying large engine nacelles beneath them.
The bombardier is accommodated in the glazed nose, and the other end of the fuselage carries a turret with two 23 mm cannons.
These features make it resemble the World War II medium bombers that preceded it, but the swept tail surfaces and the pilot’s bubble canopy and ejector seat were more similar to other aircraft of its own era, making it a blend of old and new features.
