While there are concerns about the new F-35 radar fitting into the aircraft, it's not accurate to say it definitively can't fit. Lockheed Martin is proposing a new fuselage design to accommodate either the current or new radar, suggesting a potential workaround for delays in the new radar's development. 

 

Here's a more detailed explanation:

• The issue:

  The new radar, dubbed APG-85, is intended for the F-35's Lot 17 airframes, which began production this year. 

   
• Potential delays:

  Lockheed Martin has raised concerns about the radar's delivery schedule, leading them to propose a redesigned forward fuselage. 

   
• The proposed solution:

  The new fuselage design would be compatible with both the current APG-81 radar and the new APG-85 radar, allowing for flexibility during production. 

   
• Why the concern?

  Advanced radar technology is challenging to develop, especially when it needs to integrate seamlessly with other aircraft systems. 

   
• Mitigation strategies:

  If the new radar isn't ready on time, the program might need to hold aircraft at the production line or install the radar later.
