Production of the Boeing F-15 Strike Eagle is currently due to end next year, after the last of 60 F-15K models for Korea and 24 F-15SG models for Singapore are completed. But the aircraft is a contender for South Korea’s FX-III requirement for 60 more fighters, and an order for 84 is pending from Saudi Arabia, although it remains unconfirmed more than one year after it was notified to the U.S. Congress.
These two customers are driving some of the proposed upgrades that Boeing has marketed as the Silent Eagle. They are headed by the Raytheon APG-63(v)3 AESA radar that is already on the F-15SGs for Singapore. Boeing has funded and test flown a conformal weapons bay for stealth, which replicates the outer mold line of the aircraft’s existing conformal fuel tanks. An IRST (infrared search and track sensors) that is being added to the front of centreline fuel tanks on U.S. Navy F/A-18E/Fs could also be carried by the Silent Eagle.
