A supersonic no-afterburner 35000 lbf mid-bypass (whatever they mean by that) turbofan, cheap enough (to build and maintain) for civil variation, designed in two years would be a pretty impressive thing tho. If it existed. Especially from a company whose biggest previous offering is a 900lbf turbofan.

The F-35's F135 "only" has 28000lbf dry thrust, and the plane tops out at 1.6, while Overture is supposed to reach 1.7 (and supercruise, which the F-35 can not do).

Although in fairness the Tu-144D had engines specced at 54 and (like Concorde) cruised at M2.

On the other hand, it was even less efficient and economically justifiable than Concorde, and the entire thing was shuttered in 1983, after only 6 years, and regular groundings (Tu-144 only flew scheduled 103 times before the programme was cancelled, BA alone flew Concorde near 50000 times, and the class logged more than a million flight hours.)

But here all that exists is a Boom PR release.
