"“This will be a next generation capability being introduced by Ursa Major for hypersonic technology,” Jablonsky said in an interview ahead of the contract award. “This will be a storable liquid rocket engine capable of hypersonic speeds in atmosphere or exoatmospheric, and nothing else like it...

I think the ALBM it's going to be that LFR-powered Ursa Major design based on the images.

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...

If it’s going to complement it should be in the larger payload “complementary” area.

Yes. But it was Ursa Major that paid for the content. they are not involved in the highly additively manufactured scramjet engine.

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.

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?

Is there zero evidence that the USAF will come in on the USN's Blackbeard (MACE program winner) Affordable Aeroballistic/Hypersonic Missile?!? That would make sense to me especially with the growing F-15EX procurement numbers. They could (depending on size/weight) likely haul 4 while carrying 3...
