The United States Marine Corps has recently accepted six F-35B fighter jets without the final radar system, marking the first instance of a batch of the advanced aircraft being delivered without its primary sensor. This development is attributed to ongoing delays in the introduction of the new AN/APG-85 radar, a critical component of the forthcoming Block 4 upgrade.
According to defense officials, the lack of the AN/APG-85 radar system will not impact the fighter jets’ operational capabilities in the short term. However, the radar will prove essential for the aircraft’s air-to-air capabilities and long-range target detection, features that are expected to be fully functional once the AN/APG-85 is integrated in the future.
The AN/APG-85 radar represents a significant upgrade to the existing F-35 radar system, bringing improved detection capabilities, advanced electronic warfare features, and the ability to detect and engage multiple targets simultaneously. These enhancements are expected to grant the F-35 fighters enhanced situational awareness and air superiority capabilities.
While development delays have pushed back the delivery of the new radar, officials indicate that the production of the aircraft will continue uninterrupted. This means that hundreds more F-35s could be delivered to various branches of the US military, including the Marine Corps, Army, and Navy, before the new radar system becomes available.
As part of the Block 4 upgrade, the AN/APG-85 radar is slated for integration across the F-35 fleet, with estimated deliveries beginning in 2028. In the meantime, the accepted F-35Bs will be modified to accommodate the radar system once it becomes available.
The delays and subsequent modifications are likely to have a minimal impact on the operational readiness of the F-35 fleet, as pilots will continue to operate the aircraft with its existing advanced avionics and sensor systems. However, with the radar playing a critical role in the aircraft’s combat capabilities, its absence may reduce the F-35’s air-to-air combat effectiveness during its initial deployment.
