oooh, swing wing. Where have I seen that before?

plz

bring back reusable Energia while their at it too

Not even DC-X vertical landing technology: pic related is a proposed strap-on LRB for the Soyuz successor that would use the Buran's automated landing software after it ran out of rocket fuel, using a small turbojet for a powered landing.

yep

I'm sad Energia never put their flyback boosters into production. They even had a prototype they sent around to aerospace exhibitions.

He might have been taking about the flyback-booster development program. Never made it past concept, sadly. All that is left is the Zenit rocket, also going away due to Sea Launch collapse and Ukraine conflict.

This is exactly the scenario that is scaring Arianespace shitless. Thus the various crash programs to reduce the cost of operations: the smaller Ariane 6 design, use of Soyuz and Vega for smaller payloads, and pie-in-the-sky reusability concepts like Adeline.

This isn't the first flyback concept. Russia proposed flyback boosters as well, but never got the funding to fully develop it.

still a possibility for Angara's A5 side cores.

the funny thing is that detachable engines is going back to the Atlas ICBM roots. The original Atlas had three engines at launch, and the two side engines were jettisoned, leaving the tanks and the center sustainer engine.

This would be the first time trying to recover those engines. The effort would be similar to recovering the old Stardust probe and Corona spy satellites. But really, ULA is announcing this just to keep up with the Joneses, since SpaceX is making such a big deal of their own reusability plans.

sigh. I wish. SpaceX is the only entity with a realistic plan for reuse to bring down launch prices. The secret sauce is clever design using existing tech rather than advanced technologies. The nine engine cluster allows a small enough thrust to do vertical landing after reentry.

Skylon is another attempt, but it is barely at the point of qualifying the the cutting edge air-breathing rocket engine. They are a decade away from even a test flight. Even if built, the economics might kill them like it did the Space Shuttle and Buran.

Other reuse projects all bit the dust:
* DC-X / Delta Clipper
* X-33 / Venture Star
* Rotary Rocket
* Russian reusable flyback boosters
