It is commonly said that delta wing designs lose an above average amount

true, and if why does this occur? Also, how does this reputed flaw

Delta wings are typically a low aspect wing (stubby) which requires a
higher angle of attack to generate additionally lift than a higher
aspect (think Long and slim). Higher AOA results in higher drag,
hence one needs more thrust to maintian same speed.

I'm told that the F-106 was famous for it's first bat turn but after
that it was pretty much toast.
