Is the Navy’s 6th-Gen Fighter Already Flying?

Over the last two years, there’s been steady movement across classified funding lines, defense contractor activity, and base infrastructure… enough to suggest that the Navy’s sixth-generation fighter is no longer a future concept.
While still unacknowledged, the program commonly referred to as F/A-XX (and possibly designated F-55) appears to be in active flight testing.
Here’s what supports that conclusion:
Link Plumeria: The Black Budget Trail
A classified program line called Link Plumeria has appeared in recent Navy budget documents. The initial funding level was consistent with low-rate fabrication and flight integration. The follow-on decrease points to a transition from design to field testing. This matches known patterns for stealth programs once they exit the design and simulation phase.
Contractor Activity
Boeing is widely suspected to be the lead, with supporting roles by Northrop Grumman on low-observable technologies and systems integration. Raytheon and L3Harris are likely involved in EW and sensor packages. Palantir’s involvement in operational-level mission data systems and autonomy infrastructure has increased across multiple domains and may be relevant here as well.
When these companies converge under tightly scoped language with few deliverables in the unclassified space, it usually means hardware is being assembled or flown.
Flight Test Locations
The likely development path begins at Plant 42, where stealth aircraft are assembled and prepped. Ground testing, taxi trials, and system integration typically occur there.
Groom Lake would handle radar cross-section validation, envelope expansion, and signature testing. That’s standard procedure for sensitive airframes requiring full security and advanced telemetry.
Tonopah Test Range, which has seen recent upgrades, would come into play once the system transitions toward operational testing. If the aircraft ends up there, it strongly suggests a move toward limited IOC and mission-profile workups.
Operational Clues
While no confirmed visuals of the platform exist, there’s been a notable shift in test flight patterns, radar calibration activity, fuel deliveries, and nighttime operations around the NTTR. These are common indicators when a new platform is being flown under classified conditions.
There’s also reason to believe additional telemetry collection sites may be involved, especially for carrier-simulated ops and electronic warfare testing.
Why This Isn't the NGAD F-47
To be clear, Link Plumeria is not the NGAD F-47. It’s a separate program, run under Navy command, with a different mission set, and separate funding structure. Here’s how we know that:
The funding, testing patterns, and infrastructure support that conclusion.
If anyone’s seen changes near Plant 42 or Tonopah, that might not be routine maintenance. A new platform may already be flying. And maybe this time, it’s wearing Navy paint.

To be clear, Link Plumeria is not the NGAD F-47. It’s a separate program, run under Navy command, with a different mission set, and separate funding structure. Here’s how we know that:
- Link Plumeria is a Navy black program, funded out of Navy budget lines. NGAD and the F-47 are Air Force assets under a different acquisition chain.
- Dollar figures associated with Link Plumeria match full-scale prototyping, not research or study contracts. It’s not an add-on to an existing Air Force program, it’s independent.
- Carrier-capable requirements mean the airframe is purpose-built for Navy use, not just adapted from NGAD. No credible evidence suggests the F-47 was designed for CATOBAR ops or naval environmental hardening.
- Contractor crossover doesn’t imply shared platforms. While Boeing, Northrop, and others are involved in both programs, that’s due to expertise, not necessarily a shared airframe.
The funding, testing patterns, and infrastructure support that conclusion.
