Absurd comparison – YF-22 and JSF looked terrible in many aspects of stealth.
Actually, he’s right, there are numerous RCS issues with the PAK FA from the front and side aspects, very large ones. Some rely on technology developments, others require a complete departure from the classic design used.
RCS any lower than that of a Super Hornet
Hate to say it, but he’s partially correct here. There’s not many reasons why the PAK FA would have a frontal RCS lower than a “clean” superhornet. There are numerous issues with the T-50’s front aspect that require technology advances and aerodynamics changes to fix (I’m not talking about the engines).
From the side, naturally its better than the super. Not better than the J-20 from the side or F-35 from front and side, and not better than the F-22 and YF-23 from any aspect.
Sample comparison of small lower fuselage cross sections of the F-22 (left) and T-50. You can ignore the dBSM values (values aren’t shown anyway) that don’t take materials into account, but as the samples are to scale, it shows the effectiveness of the simple and regularly shaped F-22 against radars to the side and below the aircraft (effectively all radars for the two aircraft in this sample due to their high operating altitudes).
