Giving serious funding to small companies to rapidly develop innovative concepts applicable to AURA objectives is also a good way to keep the existing JMR/FVL teams on their toes.
The requirements, of course, are key. If the Marines want something too different than either FARA or FLRAA, the industry is looking at yet another rapid development program of an advanced VTOL craft... which is exciting, but I think the industry is getting a little tired. One of these programs needs to become a fully funded program of record and not a one-off cost share project.

After being in this business for a couple of decades, I can tell you that if the 295+ knot speed is firm, it won't be an edgewise flow rotor. It's possible to hit those speeds, but not efficient enough to have good range and be a balanced platform. The shipboard compatibility requirements and exactly which hangers it needs to fit in will also heavily drive the design for AURA.
