Yawn. It's only going to be a dozen or so and they will be used for training until the APG-85 is ready. Lot 17 F-35's which consist of 190-200 are APG-85 capable.
- The U.S. Marine Corps thus far has received six F-35B fighters without radars, as the service waits on Northrop Grumman‘s delivery of the AN/APG-85 radar, which is to replace the current APG-81, also by Northrop Grumman.
“The Marine Corps has been accepting airplanes with no radar in it, is that correct?” Sen. Mark Kelly (D-Ariz.), ranking member of the Senate Armed Services Committee’s (SASC) airland panel, asked Marine Lt. Gen. Gregory Masiello, the F-35 program executive officer, at a June 23 hearing.
“We have accepted six aircraft for the Marine Corps that do not have a radar installed,” Masiello replied. “That is correct.”
Kelly then stated that his assumption was that the Marines “want to wait for the APG-85.”
“They do,” Masiello said.
Radar mountings in the F-35’s nose are different for the APG-81 and the APG-85 radar–a difference which has helped complicate fielding of the new radar which was to deliver with F-35 Lot 17.
The Air Force has been considering an APG-81/APG-85 dual-mount bulkhead, though the latter may take two years to field.
The service’s fiscal 2027 future years defense plan (FYDP) contains $133 million in fiscal 2031 for retrofitting 14 F-35As with APG-85s–a unit cost of $9.5 million per radar, and outside the FYDP the service said it plans to spend about $1.6 billion to retrofit another 167 jets with the APG-85.
The Air Force, Navy, and Marine Corps have 832 F-35s out of a global inventory of more than 1,300 on 42 bases and 13 ships–10 U.S. ones and three allied ones, according to the F-35 program.
The APG-85 is critical to the 55 upgrades in the Block 4 program–22 of which have fielded so far, including seven last year, and six on target for this year, Masiello testified on June 23. For full functionality, the APG-85 and Block 4 require 62 kilowatts to 80 kilowatts (kW) of cooling, however, versus the 32 kW on the plane now.-
The APG-85 is in a whole other lever of power output and capability and so is the APG-81 compared to foreign fighter AESA's including their supposed "GaN" which doesn't have the capabilities of the APG-81 a non-GaN AESA.
