The 5G F-35 has an RCS of 0.005m2, about the size of a golf ball. However, from the rear, it looks much bigger because of the exhaust nozzles, the same problem we saw with the 5G Russian PAK-FA (T-50). For comparison, the 5G F-22 has an RCS of 0.0001m2, about the size of a bumble bee.
The older 4G MIG platforms have an RCS of 15m2, down to 3m2 for the MIG-21. The SU-34s RCS is 1m2. SU-35s are 1m2 to 3m2, according to web sources. The PAK-FA (T-50) has an RCS of 0.5m2, about the same as a Tomahawk cruise missile. None of those planes are truly stealthy.
