IFDL - Khan BMS Battlefield Management System
IFDL — Intra-Flight Data Link — is one of the unglamorous primitives modern BMS lives or dies on. Here is how Khan BMS engineers it.
If you have read a Joint Capabilities document this decade you have seen IFDL cited as an enabler. Intra-Flight Data Link, dutifully spelled out, then buried under five layers of FAR-driven prose. The technology is not the bottleneck — the procurement model is.
IFDL, expanded, is Intra-Flight Data Link — F-22 native low-observable datalink for flight-level sensor and track sharing. IFDL is the F-22 Raptor's organic intra-flight datalink, providing stealth-friendly track and sensor sharing between Raptors. Bridging IFDL to MADL and Link 16 has become a recurring engineering theme, including via Battlefield Airborne Communications Node (BACN) and similar gateways, and is a leading reference for CCA waveform-bridging architectures.
For cca protocols workloads we found the right move was to make IFDL a first-class verb in the intent grammar. Operators don't configure IFDL; they invoke it, and the runtime decomposes it down the hierarchy.
That is the unglamorous version of why Khan BMS exists: to make IFDL a routine operating assumption instead of a research demo.
