The overall objective is to identify, develop, mature, and demonstrate technologies that enable refurbishable high speed (M>3) capability for intelligence/surveillance/reconnaissance (ISR) and strike platforms by 2028, and for quick-turn fully reusable systems by 2035.
Background: The High Speed Systems Division within the Air Force Research Laboratory (AFRL) conducts research to develop, demonstrate, integrate and transition high speed vehicle technologies that provide affordable, revolutionary capabilities to the warfighter. Technology developments in high speed systems provide for cost effective weapons and aerospace vehicle platforms capable of accurate and timely delivery of payloads worldwide in support of the Air Force’s desire for rapid, persistent strike/ISR and affordable, responsive space launch. The time frame for development of these capabilities is such that the technologies are demonstrated and matured to a technology readiness level of 6 for mid-term transition in 2025 (persistent engagement) and far-term by 2035 (responsive space launch).
Objective: The overall objective is to identify, develop, mature, and demonstrate technologies that enable refurbishable high speed (M>3) capability for intelligence/surveillance/reconnaissance (ISR) and strike platforms by 2028, and for quick-turn fully reusable systems by 2035. It is envisioned that the earlier demonstration systems will be air-launched utilizing rocket-boost to reach hypersonic cruise speeds, and later employing combined cycle engines that permit runway operations. Those
technologies that advance the state-of-the-art and that mature the science base to high technology readiness levels will be further considered for incorporation into the AFRL strategic plan.
Sub-Tier Objectives: The Technical Objectives below further define the desired technology areas.
1. High Speed Experimental Sciences
2. High Speed Propulsion Systems
3. Aero-Structures
4. Modeling and Simulation (M&S)
5. Vehicle Design and Integration

bobbymike said:Army developing artillery round with increased strike capability
The Army is scheduled to hold a system requirement review in October for a new artillery round, a munition that is expected to help the service maintain battlefield "overmatch."
Moose said:I'm not sure why you would think that. Let's compare to LRASM, which had a program launch in 2009 and was approved for limited production in 2014. LRASM in air-launch configuration is essentially "just" a JASSM with a new guidance package. LRPF needs a new airframe, motor, warhead(s), launch canister, and either new or borrowed guidance. 2027 to develop, test, and reach IOC is a pretty reasonable, perhaps even optimistic, goal.
Obviously our perceptions have changed, this is 11 years to build a ground launched missile. As you clearly put it, it is not like we are starting from scratch with, "Hey what's a missile?" We have 60+ years of this. Didn't we develop Thor and Jupiter 'from scratch" in like 5 years?sferrin said:Moose said:I'm not sure why you would think that.

"Should" in the sense that, "back in the day we fielded stuff much quicker". Considering this new rocket is using current technology in a different shaped airframe, what's the holdup? "Back in the day" they were having to invent new ways of doing things most of the time, they couldn't just grab something off the shelf. Yet another example of how far we've regressed. China and Russia don't seem to have that problem.

a second to your motionDrRansom said:bobbymike said:The Supercomputer That Can Spot Mobile Missiles
This sounds like bog standard machine learning for image recognition. A useful technology but not new?
As for the army weapon, the delay could be because the Army wants the missile to have a non-ballistic trajectory. The iskander apparently has a non-ballistic trajectory to evade missile defenses, the Army may want that capability.
If that is the case, then there is little previous work on those lines?
Also, LOL at buying new ammunition to maintain "overmatch". The Army has the oldest guns of any first rate power. Furthermore, buying expensive guided shells is an awfully pricey way to combat cheap shells fired at longer distances. What I don't get is why there isn't research on achieving say 50% accuracy improvement for under 1000 per round. That seems to be a better research line than more 50k+ excaliber rounds.

Maybe the army wants a more aggressive non-ballistic trajectory? Something with high energy turns to evade defenses? The atacms, iirc, does non-ballistic for superior penetration capability, but not for evasion.
Another issue the army might be facing is how to get cluster bomblet performance from a non-cluster bomb missile. There's been work there but so far nothing concrete.
