Not trying to get off topic, but it isn't all that meaningful or productive to look at the GCAP (Tempest) through the lens of the F-47 or J-36, or otherwise to compare the GCAP to
actual 6th gen fighter programs.
This will inevitably injure British egos, but last we checked,
the GCAP intends to incorporate vertical control surfaces,
.
Unless BAE, Leonardo or MHI got some seemingly magical technology that will render this tailed design as stealthy as the tailless designs coming out of the US and China, then it's time to acknowledge that the GCAP will in fact be a 5.5 gen fighter or a "6th gen minus" fighter like India's AMCA.
Therefore, the GCAP won't necessarily represent direct competition for the likes of the F-47 in terms of international sales, so much as just what some countries will have to settle for or otherwise make do with.
