The most difficult task of the sixth-generation fighter push in America is not to draw a more refined stealth shape or pursue an even higher top speed. It is restoring sufficient industrial sinew people, suppliers, and depth of production to produce two other distinct jets of exquisiteness without disrupting the ecosystem that (they) have to rely on decades to survive.
The NGAD crewed platform of the Air Force, or commonly known as the F-47, and the carrier-oriented F/A-XX of the Navy have often been viewed as similar jumps. They are also both intended to be based on the same modern principle; a crewed, or manned, quarterback and a group of uncrewed teammates, more commonly referred to as manned-unmanned teaming. That idea opens up capacity, but it also opens up the amount of engineering work: secure autonomy code, integration of mission systems, networking, and test infrastructure are all first-order schedule drivers.
The U.S. combat-aircraft business is much smaller than it was during the operation of several programs of Cold War era. Consolidation brought the primes into a smaller number and, what is even more important, diluted the layers beneath the primes. The actual weakness lies in the tier-2 and tier-3 suppliers that manufacture the low-glamour components that comprise the majority of lead times: high-temperature composites, custom castings, miniature propulsion, flight-control equipment and hardened electronics. Most of those inputs are single-source and it is cumbersome, time consuming and costly to have the second vendor qualified. Under two high-traffic programs can tugging on the same weak nodes simultaneously, discontinuity is likely to spread laterally in effect not only a delivery date, but test schedule, configuration stability and quality control on both lines. Human beings are the hardest to overcome.
The development of the sixth generation requires engineers and technicians, who are able to cross stealth, structures, avionics, electronic warfare and even software-defined capability. The pool is further limited by the clearance requirements and the lengthy pipeline to transform new hires into the trusted integrators. Meanwhile, a large portion of the most valuable skills, such as secure software, advanced manufacturing, model-based systems engineering, all fit well to the commercial tech and aerospace work which have fewer restrictions. Having two next-gen fighter programs running on the same overlapping peaks exacerbates churn in the areas where continuity is required the most: mission-system code, digital thread, flight-test instrumentation, and production engineering.
The stack technology is also associated with its own supply-side gravity. A sixth-generation jet will have significantly greater sensing and processing that makes power and heat design drivers. That takes propulsion decisions to a level where they incorporate engine performance, to an overall aircraft architecture. GE calls its XA100 adaptive cycle engine offering a step change in the capability of its power output and thermal management, precisely the margin of the type that advanced sensors and onboard processing feed on. However, high-tech engines impose demands on the same industrial foundation which materials, additive manufacturing capacity and special testing facilities already have.
The stealth problem is not really a theory issue but rather an issue of scale. The push to F-47-type Stealth++ coating survivability at high speed, and alleged 1,000 nautical-mile combat range in addition to Mach 2-plus speed have been in focus of public discussions. Regardless of the ultimate correctness of those particular numbers, there is an industrial implication: when production scales up, tightening of tolerances, increased sensitivity of materials, increased load on inspection, increased exposure to rework.
It is possible to find solutions to minimize the collision of the two fighter efforts without pushing it into one airframe. Open architectures and shared subsystems have the capability of turning fragmented demand into bigger and more predictable supplier runs. Timing is even more important: allowing one program to cash in high-risk items, such as propulsion, autonomy integration, advanced sensors, to reach full stage before the other gets to its peak test and production allows both to be on the same cleared teams, laboratories and ranges. And the larger CCA push may be regarded as a sort of industrial hedge, programs targeting approximately 1,000 uncrewed planes generating their own demand signal of software, autonomy, and manufacturing strategies that can cross-platform.
It is quite obvious that the two next-generation stealth fighters are attracted. The unsolved issue is that America is trying to deploy them with a supplier chain and a workforce that is that of another generation and sixth-generation complexity multiplies all the fault lines.
