It's not a brief, but I assume the AF will tread close to the vision from Grynkewich's articles:

In order to evaluate various innovations in an operational context, our team organized viable concepts into several conceptual frameworks for further analysis. The first conceptual framework included robust modernization of the planned force of 2030, but had few additional capabilities added to the mix. As such, this provided a base case for our analysis, showing us the maximum amount of capability we could extract from the force without starting major new acquisition programs. The force in this conceptual framework achieved control of the air the old-fashioned way, by rolling back an adversary’s integrated air defense system over time from the outside in until air superiority was attained over a desired geographical area.
Our second and third conceptual frameworks were a standoff force and attritable force, respectively. The standoff force broadly consisted of non-penetrating platforms delivering large volumes of weapons (including non-kinetic effects) from beyond the lethal range of threat systems. The attritable force consisted of a large number of platforms with modular payloads (either kinetic or non-kinetic) that could be reused multiple times, but that were also inexpensive enough that losing some in a high-threat environment was acceptable. Importantly, the attritable force we assessed in this conceptual framework did not just exist in the air domain, but in cyberspace and space as well.
Broadly speaking, we expected both the standoff and attritable forces to achieve air superiority through the high volume of weapons, effects, and/or attritable platforms swarming and converging in the desired space at the desired time to overwhelm enemy defenses. Yet deeper analysis revealed that neither force was able to generate enough awareness of targets much beyond the edge of an adversary’s defenses. Each could only achieve air superiority on the outskirts of an integrated air defense system. Over time, air superiority could extend deeper into the adversary system — but to get to that point the scheme of maneuver ended up resembling yet another traditional roll-back operation, albeit with cyberspace and space capabilities in play as well.
Our fourth conceptual framework centered on what many would describe as a sixth-generation fighter: a highly survivable, highly lethal platform supported by cyberspace and space capabilities.While our analysis showed this conceptual framework would be highly effective at the tactical level, it was hobbled at the operational level by an insufficient quantity of capability due to the high cost of the platform. Additionally, to achieve the effectiveness needed, the development program postulated for this program would carry a significant degree of technical risk, creating a very real possibility that this sixth-generation fighter would not field until well past 2030. In short, we concluded that the exquisite capabilities in this conceptual framework would cost too much and arrive late to need.
At this point in our study, the problem seemed intractable: we could not modernize our way out of the problem, multi-domain standoff weapons and attritable forces failed to achieve air superiority, and our only successful operational capability was unrealistic both in terms of cost and timeline. As we reviewed the analysis conducted on the conceptual frameworks in greater detail, however, several important insights came to light that would guide us as we developed courses of action.
First, we learned that modernization of some current platforms would allow them to perform some parts of the counter-air mission, including as defensive counter-air over friendly forces and suppression of enemy air defenses on the edge of the integrated air defense system. Second, we learned that we knew how to launch standoff weapons over long distances — the challenge would be giving them enough information to hit a target. We also learned that while we did not have access to the all information necessary to provide that targeting information today, we could significantly improve our ability in this area by fusing cyberspace intelligence with new space-based capabilities (such as using cubesat or nanosat technology to blanket an area of interest with overhead coverage).
If we could develop these capabilities and pair them with new and existing air-domain data sources, we would significantly improve the effectiveness of standoff weapons. Doing this, however, would require getting the right sensors in the right places, meaning sometimes deep in adversary territory. Attritable assets with the right sensor payloads provided one option, as did networking together current or upgraded airborne sensors, including fifth-generation aircraft and dedicated ISR platforms. Still, attritable assets lacked persistence, and fifth-generation assets could not go everywhere we needed them to go. We still would need a capability to penetrate and persist in the adversary air defense system. Such a capability was not just needed to employ weapons or project effects, but just as importantly to serve as a key node in what was emerging as a new conceptual multi-domain battle network.
