Digital Century series is dead for manned NGAD, has been for a number of years. It was less the big contractors won and more that PPBE just wasn't flexible enough for that to happen. Portions of it remain with CCA.
Nope, far from dead. As of early summer it was very much alive. USAF wants to produce small numbers at a time and constantly iterate. 3-6 years for each airframe iteration, with 8-16 year service life.
Each iteration could be made by a different contractor. They want to get away from “winner take all” and use CCA to incubate new contractors.
I think Ozair's comment was true for a while, but now is in a superposition of being indeterminate.
When control of NGAD reverted to Frank Kendall in later 2021, he began a process of narrowing down the official plans until he arrived at what became the terms of the 2023 RFP. During this time, he decided that the USAF would do only one crewed sixth gen fighter and, by all appearances, that it would be the large Battlestar version. With a unit price of 300m, it very much appears to be a durable asset of high capability, with ownership costs and modernization handled by the pre-Roper approach of MOSA, gov owned IP, competitive sustainment, and agile software development. That is, it appears that Kendall did not embrace Roper's interest in applying CCA lifecyle management approaches to crewed fighters. Rather than Roper's approach of avoiding modernization and sustainment, Battlestar aimed to excel at them, cheaply.
However, things spun out of control late last year with Sentinel and the BCA, and suddenly Kendall was being controlled by events rather than vice versa. Since then, Roperized crewed aircraft are back on the table as an option, while CCAs, whose rapidly improving AI was previously just considered as gravy, are now in the running to become the new meat & potatoes as well. But NO approach can currently be described as The Plan, which won't exist until the incoming officeholders make their choices over the next couple years. It is NOT true that Roperized crewed aircraft have replaced Battlestar, but they are contenders again, and could. Many people think they have more momentum, and fit the budget better.
Not for nothing, CJCS Brown is a fan of light fighters (MR-X) and CSAF Allvin has Roperish inclinations. But neither they nor the study participants will make the call. It might be the next Secretary of the Air Force, or the new SecDef, or Congress that decides -- only time will tell who delegates and who the choice falls to.
