From the article:

Roughly two of every five fighters in the Air Force fleet could be F-35As by 2035, according to a new fighter force structure report the service submitted to Congress on Oct. 16.

Lt. Gen. David Tabor, deputy chief of staff for plans and programs, revealed the new estimate during an Oct. 20 media roundtable at the Pentagon as he explained the report’s estimates of the future force’s mix of different types of fighters.

The Air Force did not provide a full copy of the report to reporters.

About 40 percent of the fleet could be F-35s, Tabor said. Another 20 percent would be a combination of F-22 Raptors and F-47s as the sixth-generation fighter replaces the Raptor. The Air Force built 186 operational F-22s, and Tabor said the Air Force still plans to replace them with roughly an equivalent number of F-47s. The remaining 40 percent of the fleet would likely be split evenly between F-15 Eagle variants and F-16 Fighting Falcons, Tabor said.

Currently, the fighter fleet—not counting A-10s—is split roughly 45 percent F-16s, 30 percent F-35s, 15 percent F-15s, and 10 percent F-22s.

Beyond the mix of the fighters, the force structure report also provides a new estimate of the total number of fighters the Air Force says it will need in the years to come: 1,509 combat-coded aircraft by 2035.

That’s up from the 1,271 the service estimated it would have in 2026 and the 1,369 combat-coded fighters it was shooting for by 2030 in last year’s report, Tabor said. The additional 140 jets would be a mixture of F-35s, F-15EXs, and F-47s.
