APX-123

摘要

1. The introduction of Mode 5 has led to many orders for the APX-123 as operators upgrade from older APX-118 units and maintain compliance with the latest IFF standards2. While orders supporting new-build aircraft will continue, major APX-123 retrofits will begin to wind down in 20223. The layout of the APX-118/123 IFF units is highly upgradable, and they should see further updates in the future.
