What type Speed Racer could be ? it seem to have very little engine, taking the way more for a missile size UAV

So this looks like an effort to develop a low cost cruise missile where the development software and process is as much the demonstration as the final product's performance. That sounds a lot like NGAD's demonstrator - demonstrating the development process speed, not focusing on product performance. I'm skeptical, but the progress of the B-21 in this regard bodes well for these time and cost cutting modes of design.

Is there any statement, from anyone in the USAF, that would lead one to believe that NGAD demonstrator was not focusing on product performance? One would think that any demonstrator would be focused at retiring major areas of risk associated with the overall vision. Sure, a new design and production process may be one such thing, but it likely wouldn't be the only thing they would have liked to focus on.

@Josh_TN :
Wait wait.
There is no lifting body effect
There is a lower keel
The Wing sweep angle is acute.

This design smells speed all over it (low alpha cruise, fairly small governs, axis symmetrical body (or somewhat), high sweep). This is not our usual subsonic suspect.

Nothing confirmed, but there was a lot of speculation that a lot of the records that were supposedly broken producing the demonstrator (whatever form it took) were related to production and not performance. It would be in keeping with the digital century series mantra the program is pushing. But no, nothing is known in open source.

I assume the wings were folded for carriage. Isn't the engine class this thing uses no where near what would be required to be super sonic?

Engines are a couple of TDI's small turbojets, either J85s (200 lbf) or J7 (70lbf). That's not a lot of thrust.
The unusual number of engines may be simply due to the fact that there are so few small turbojets that in order to get your right amount of thrust you need more than one. For example, i don't think there is much available between 200 and 600 lbf, so if you need 400 lbf, voila, you use two J85s.
Also, as pointed out, i don't see any attempt at area ruling. I think this is firmly subsonic.

Pretty low fineness ratio unless there's a rocket in its ass. Although the folding lugs are nice.

Difficult to see what the point of this is apart from some pretty niche missions

"Our robust digital engineering and advanced manufacturing practices deliver affordable dominant weapon systems to the #warfighter with the speed and lethality required to maintain overmatch."

*Rolling eyes* It sounds like something an AI software would generate trying to make the shortest grammatically correct sentence that uses ALL the buzzwords. Why does everyone in the industry feel the need to write this way? And then the buzzwords are on rotation, like fads. :mad:

Sorry, end of rant.

I have 1980s video tapes, one called Guided Missiles, IIRC that uses pretty much the exact language describing weapon systems. The more thing change the more they stay the same.

Regarding speed racer, I am wondering if that is not a very low nap of the earth high speed vehicle that could be released at very low alt.
See the ventral keel, the high wing loading wing, the ejected part after launch to garentee the optimal placement and perfect calibration of governs as adding stability by aft high drag index, the attention to horizontal aspect stealth (side fuselage geometry)...

An illustrative concept of a future unmanned aircraft that might field capabilities of the type that the USAF is now seeking for its Next-Generation Multirole Unmanned Aircraft System Family of Systems requirement. (Lockheed Martin)

I must say, I was just thinking about the design requirements for survivable loitering drones and this picture pretty much hits it head on.

The time frame is suspiciously close to the B-21 IOC. Given the secondary emphasis on more endurance and survivability, I wonder if they don't envision B-21's with A2A drone escorts operating well outside the range of tac air. This would make a lot of sense in the Pacific Theater where distances are vast and local bases are few compared to the Chinese mainland.

Well if you want to believe the rumours the B-21 already has a drone ‘associate’ in the alleged RQ-180.

What's disturbing is hearing somebody speak like that in person. Eyes rolling all over the place.

I'd imagine the B-21 will be carrying its own escorts.
