Definition/Scope: The communication system known as Tactical Digital Information Link (TADIL) A/B [Link-11] employs netted communication techniques and a standard message format for exchanging digital information among airborne [TADIL-A] as well as land-based and shipboard [TADIL-B] tactical data systems. Link-11 data communications must be capable of operation in either the high-frequency (HF) or ultra-high-frequency (UHF) bands. A number of intelligence platforms such as RIVET JOINT that conduct signal intelligence (SIGINT) data collection, including communications intelligence (COMINT) and electronic intelligence (ELINT), uses TADIL-A/B. Link 11 provides high speed computer-to-computer digital radio communications in the high frequency (HF) and ultra-high frequency (UHF) bands among Tactical Data System (TDS) equipped ships, aircraft and shore sites. Currently the Fleet is using a number of different data terminal sets to provide Link 11 functionality, these include the AN/USQ-74, AN/USQ83, AN/USQ-120, AN/USQ-125 and other Data Terminal Sets. The new Common Shipboard Data Terminal Set (CSDTS) card set provides all of the capabilities of the older Link-11 data terminal sets including Kineplex, Single Tone, and Satellite transmission capabilities. It also incorporates multi-frequency Link 11 enhancements, allowing the operation of up to four parallel channels among participating units. Link 11 is to be replaced by Link 22.
