Spline,
Current progress would indicate 214 knots by end of the year. As you are aware they have gotten all of the easy knots. Bell is probably in a similar position on the V-280 except their baseline is starting at 300 Kts+.which they reached a long time ago.

I guess “imminent” is longer than three months.

More gaslighting from the Sikorsky-Boeing PR team. Apparently their definition of roaring through milestones are:
1. Flying only 26 hours in 20 months at the most benign gross weight/cg.
2. Achieving a pathetic top speed in level flight of 211 knots against an original target of near 250 knots (later reduced to 230 knots which they still could not achieve).
3. Not flying any gross weight/altitude/range expansion flights.
They also state the team is putting "the final touches on an official pitch to replace the U.S. Army’s long-serving UH-60 Black Hawks." So they admit they have completed all they can do with the SB-1, even though they were given a govt funded one year extension to the FLRAA demo program deadline to try to make it appear they were a viable alternative to the 300Kt++ Bell V-280, It appears their plan is to lobby the Army to water down the FLRAA speed/range requirements so much that even the SB-1 could meet them. If that fails I expect them to no bid the program and try to get FLRAA cancelled because there are not two competing for the development contract.

Doing the Math
Interesting that despite the S-97 being promoted as a test bed for it’s bigger brother the SB>1, it has only accumulated 93 flight hours. So the two X2 technology aircraft combined have only 119 flight hours, compared to over 200 hours on the Bell V-280.
I fear that politics and the changing world post COVID may make a bigger difference in the future of FVL than the obvious technical maturity benefits of the V-280.
Let us all hope that sensibility and trust in science prevails in 2021.

I just see two very expensive, very large bits of complex gear, neither of which appears fit for the purpose. They are too big to do recon and too fragile to do combat.
The idea of helicopters massed to defeat tank armies is dead as a dodo, as was demonstrated in the recent Armenia/Azerbaijan war.
Aging a dumb idea does not make it smarter.

Fact is that reality is what Washington decides it is.

The Raider and Valor (correction Raider-X and Invictus) are being designed for recon and attack. I concur, that mission may soon be made obsolete by unmanned technology.

[QUOTE=CTR;10958698]Both the SB>1 and the V-280 primary mission is troop transport. As long as soldiers need to get in and out of battle, this mission is not going away.

No biggy, but you mean the Raider-X and the Bell 360 Invictus (hardly an easy-to-remember name)
I can't post URLs but like how the V-280 Valor transport flew autonomously in December 2019, the B360 will be built to accommodate pilot-less flight.

The big plus of the Blackhawk for this mission is that it is extremely rugged, rather nimble and small and not excessively complex and expensive. Almost the opposite of the new vertical lift high speed platforms. The most dangerous phase for the helicopter in combat has historically been the landing/de- boarding phase. And that is the phase where especially the valor is a huuuuge and beautiful target with lots of critical parts widely spread and is also rather limited in its agility and descent rate compared to the nimble Blackhawk. I'm not really convinced that they are not going to cancel the current bid. For certain special missions the new platforms surely offer very interesting possibilities but I have a hard time to figure them as real replacement for the rugged 'bread and butter' combat mule that is the Blackhwak.

Fact is, the H-60 cannot do the missions the Army has envisioned for FLRAA and a tilt rotor can. Of course, this is the SB>1 thread, so we should mention that vehicle, which in nearly two years of flying hasn’t reached Vh, so perhaps it’s not well suited to the missions, either.

Of course, Sikorsky also claims the same thing with Defiant, but over 5+ years of trickled flight testing neither it nor S-97 have demonstrated anything approaching even what the V-280 has done in YouTube videos or in front of public audiences.
