IIRC, UM is also working with AFRL to fly the liquid fuel draper engine equipped Angry Tortoise in the coming months first at WSMR and then over the Pacific at higher Mach. This appears to be a pitch to continue to evolve the engine and put together some sort of weapon system utilizing it...

The cover by Chris Foss, to the 1971 Mayflower Books edition of the novel 'Rockets in Ursa Major' (1969) by Fred & Geoffrey Hoyle, as far as I can tell it may be the only spacecraft interior in the artists output.

Ah, jeeze, so it does. Failed my reading comprehension this morning. More comments to follow on the Ursa Major thread.

Good point as they also have a 7" diameter airframe, I wonder if Ursa Major will develop a 7" launch booster for the ground-launched Hellfire/JAGM to boost them up to M1.2 to get them past the transonic drag regime to give them the same range as the air-launched versions?

Kh-22 is hypersonic?

Some info a Russian arms ship that sank in 2024 including the line The cause of the Ursa Major's sinking appears to be kinetic. The shipowner told media that there were three explosions and a 20-inch hole in the shell plating, and the captain confirmed that the hole's ragged edges were bent...

...few years from a wide variety of suppliers, the major engine manufacturers and engine-manufacturing-adjacent startups like Hermeus and Ursa Major will need to begin offering multiple drone-sized engines to capture market share. Just look at China's mini-turbojet market, where the economies of...

OH, as @Josh_TN pointed out, this is specifically for an Army program, so RAM is probably not related at all. Then again, no guarantee that photo is linked to the test, either. Space News has a totally different photo of a 6-inch rocket motor test, which also might not be related in any way...

I think, really it has to be a name from the Boeing or Lockheed tradition, although ,of course, Boeing incorporates McDonnell, who in turn incorporated Douglas, and Lockheed incorporate Martin, and GD/Convair. Trouble is, Boeing names are rather lacklustre, for fighters, anyway, 'Peashooter...

...as well. I do know that there have been several DoD contracts over the past few years that have been working on highly loaded grains. Ursa Major and Anduril have been public about it, but there is a mention of a similar program on Northrop Grumman’s website as well. I would assume that L3...

If they've found a way to 3D print it, instead of using mandrels for the core, that would open up a lot of possibilities for controlling surface area geometry. But then you probably wouldn't be able to print/cast it in place so you'd have to load the billet of propellant into the case which...

Anton Petrov has a video to do with this galaxy:

I looked at it from the SM-2 but your right. Yes but one can Hope that there fas enough for it. I have to look into that again but if i remember it right an improvement would be achieved.
