MADL

TECHNICAL DEFINITION

The Multi-Function Advanced Data Link (MADL) is a specialized, low-probability-of-intercept/detection (LPI/LPD) secure waveform and network protocol primarily used by 5th-generation stealth combat aircraft, such as the F-35 Lightning II, for robust, high-bandwidth tactical data exchange and voice communications, critically supporting C4ISR and JADC2 operations in contested environments.

BACKGROUND

Multifunction Advanced Data Link (MADL) is a fast switching narrow directional communications data link between stealth aircraft. It began as a method to coordinate between F-35 (the Joint Strike Fighter), but HQ Air Combat Command wants to expand the capability to coordinate future USAF strike forces of all AF stealth aircraft, including the B-2, F-22, and unmanned systems. MADL is expected to provide needed throughput, latency, frequency-hopping and anti-jamming capability with phased Array Antenna Assemblies (AAAs) that send and receive tightly directed radio signals. MADL uses the Ku band.

SYNONYMS & ALIASES

• Multi-Function Advanced Data Link
• F-35 Data Link
• Stealth Data Link
