Which adapter designation mounts rail launchers on F-15C/D/E pylons?

• A. ADU-552 adapter
• B. ADU-551 adapter
• C. ADU-553 adapter
• D. ADU-550 adapter

Answer: (A)

Adapters are the interface pieces that connect a launcher or store to the aircraft pylon. Each designation specifies the exact mounting pattern, spacing, and fit required for a particular combination of pylon and launcher. For F-15C/D/E pylons, the rail-launcher setup uses the ADU-552 adapter because it is the interface designed to align and secure the rail launcher with those pylons, ensuring proper clearance, retention, and electrical/mechanical compatibility. Using a different adapter would mean the launcher wouldn’t mate correctly with the pylon, risking misfit, clearance issues, or insecure mounting. The other adapters exist for different platforms or configurations and do not provide the correct interface for the F-15 rail launcher arrangement.
