Worthwhile read from Aviationweek on Roper / NGAD & Digital Century Series topics covered in the last few pages of this thread. Like many, I was fascinated by the NGAD update from a couple weeks ago. This must be Roper's counter to the criticism he's faced from what I would assume to be the major contractors like LM & Boeing (via the Loren Thompson shill articles cited in previous page and elsewhere). Interesting to think what will happen to the aerospace industry if the USAF owns the IP on these NGAD designs and goes away from winner takes all competitions like JSF.
The "elimination" of monolithic platforms and NGAD as a "portfolio" also caught my eye. Perhaps designs no longer need to make trade-offs on certain elements like size, speed, range, lo, payload, agility etc. trying to find the perfect blend in a single package. We might see manned & unmanned platforms that focus more heavily on some capabilities over others perhaps? The article also notes that recent budget information on adaptive-cycle propulsion engines suggests flight testing by mid decade.
My own guess would be that NGAD will further split sensor and shooter roles among platforms. High speed, lo & agile platforms will go out front searching for targets but will be unarmed (since internal weapons carriage seems to be the biggest weakness for current 5th gen). The forward platforms will then send target info to the second platform which is stationed some distance off but carrying a large magazine of long range weapons. These platforms are likely a mix of manned and unmanned depending on environment.
How a massive budget cut, a DARPA program and a lengthy internal debate transformed the NGAD program.
