I wonder why none of the contenders picked up the "swiveling tail rotor" concept, especially for FARA.
I suspect it would be both mechanically simpler (no need for a bendy gearbox) and propulsively more efficient to use a ducted fan and vector the thrust with vanes in the exhaust.
The other thing is that Army is only asking for 180 knot cruise and 205 knot dash. Such speeds are achievable without the need for an auxiliary propulsor. Army may welcome more speed, but it doesn't appear they will be willing to pay too much to get it. So a swiveling tail rotor or vectored thrust may be considered too much complexity, weight and cost for a FARA bid.

To reach 180-205 kt in level flight is not an easy task with a conventional helicopter, but indeed feasible (G-LYNX).
However, to demonstrate that speed with an experimental aircraft is one thing. But to deliver an operational helicopter capable of 180 kt cruise speed is something very different. In the end fuel burn at given cruise speed may be an important factor.

Range at speed is probably also the main driver for internal weapon carriage, for reduced drag.

FARA first look #1 - @Sikorsky Raider-X proposal for @usarmy Future Attack Reconnaissance Aircraft - 20% larger than S-97 Raider, side-by-side cockpit, large internal weapons bay, single @geaviation T901, redesigned rear fuselage
The chine along the forward fuselage seems to be making a nod toward RCS management, but nothing with a big spinny thing on top is going to be too stealthy.

Also, they're not showing the gun required for FARA. Perhaps it stows somewhere, again for drag reduction?

The requirement is 185 Kt or better at mission gross weight which the Army would have shared with the interested parties. As you said, flying a prototype at those speeds is one thing, but the OEM's have to convince the Army that their designs are capable of cruising at those speeds in the configurations the Army mandates while also meeting other requirements.

I am going out on a limb that Boeing will likely be rather conventional in their offering. Have not seen any significant innovation out of them in a long time when it comes to rotorcraft.

FARA first look #2 - @karem AR40 active-rotor winged compound - electric individual blade control, swiveling tail-rotor becomes propulsor, speed 210kt+, partners @northropgrumman for production and support, @raytheon for mission system
That looks like a whale.

I'd like to see a comparison in top speed, high speed vibration loads, required horsepower, and range between a close coupled rigid coaxial vs a compound wing.

Karem, always good for a surprise!

Manufacturer Boeing is continuing to shroud its US Army Future Attack Reconnaissance Aircraft (FARA) proposal in secrecy, on grounds that any other strategy would risk giving up commercially sensitive design specifications and associated technology to another competitor.

Despite all other industry participants having made their offers and designs public, Boeing has consistently taken a different approach and ahead of a downselect decision in March 2020, when the field will be cut to two for a final design and build stage, it remains unclear if the OEM will eventually unveil the aircraft in question.

Boeing's prototyping subsidiary Phantom Works is heavily involved in the campaign, on hand to support rapid prototyping and technology maturation for the FARA platform.

'We are typically involved when there's a clean sheet opportunity, a brand new requirement or a combination of requirements coming together that necessitate a new capability,' Mark Cherry, VP, general manager of Phantom Works said.

The organisation is also capable of developing digital designs at speed, in order to reduce production time frames, he made clear.

Like all other competitors, Boeing's design has already met a host of mandatory items including a minimum cruise airspeed of 180kt, maximum 40ft rotor disc criteria, max gross weight of 14,000lb (6,350kg), and is 'acutely focused' on other key items such as sustainment strartegies, data reliabilty, affordability and maintainability, according to Shane Openshaw, FARA programme manager at Boeing.

Aside from those general areas, it remains unclear exactly how Boeing is investing its FARA funding of $772 million, underwritten by an Other Transaction Authority contract and awarded by the US Army in April.

'At this point I can't [talk about how the money is being spent],' Openshaw said, though did clarify that some had been used to fund initial design review risk reduction activities.

During AUSA competitor Sikorsky released a rendering of its FARA proposal - Raider X - a variation of its in-development S-97 Raider and for which it has been given $938 million.

but they are keeping quite about their bid so that's sort of strange. It's certainly not the type of program that you want to throw in fancy tech that you don't have any hardware to show for.

I tend to agree. Odd, Karem usually has an eye for aesthetics.

I actually like the Karem submission the best, so far, as it looks the cleanest of all of the designs. I also like their tail rotor design solution. The Raider X looks more like a flying boat, the AVX like a flying shoe box, and while the Bell submission is interesting to look at, it reminds me of everything we've seen before, with the exception of the asymmetric single engine.

so who'll win the FARA ?

1 Sikorsky Raider-X
2 Bell 360 Invictus
3 Karem AR40
4 AVX Aircraft CCH
5 Boeing
6 No one

My exact thought too. I am now only wondering why they went 3 blades on the rotor. Is it possible that the rotor stops during high speed cruise?

Another pic... I like the compactness of this concept.

1 or 2, And whichever one gets picked will look WAY more vanilla than their concepts.

Looking at the picture from VTOLicious, the rotor blades for the Karem FARA are very wide chord and a pretty complex design. Wonder if they plan to slow the rotor system at higher speeds?

Two pictures from Vertical Flight Society shows the interesting rotor blades, where the wing folds and the tail rotor/thruster.

Army is apparently going for RAH-66 Comanche Part 2, hopefully this will fare better than Comanche, Army does not have good track record in procuring new helicopters.

My money is on Bell taking FARA and Sikorsky taking FVL. Bell seems to be the lowest risk design and they have plenty of experience in this realm.

Yeah I was just thinking it looked like a medium bomber with a rotor in place of piston engines.

Without knowing more about Boeing's entry it's hard to put anyone but Bell and Sikorsky in 1 and 2, maybe with some debate about which gets which spot. The Karen and AVX concepts are interesting and I'd love to seem either or both fly, but I don't see anything with either of them that clearly puts them ahead of the big teams.

One point will be to assess if or not we will have a widening gap b/w tilt rotor platforms and 199ers.
The immediate quest to replace the 58 might simply lead to a short term procurement of a couple hundred of airframe and provision for a next Gen platform.
