Link-22 a secure radio system used by NATO for beyond-line-of-sight (BLOS) tactical data communication. It enables various platforms like ships, aircraft, submarines, and ground stations to share real-time tactical information like: Friend or Foe (IFF) identification, Track data (position, speed, altitude), Weapon engagement data, Electronic warfare information, Meteorological data Version History: Link 11: Developed in the 1960s as a basic data link system for air defense. Link 11A: Expanded capabilities and data types supported. Link 11B: Further enhancements, including encryption and improved message formatting. Link 22: Significant upgrade with increased data bandwidth, new message types, and improved robustness. Link 22B: Current version with ongoing improvements and features like Link 16 interoperability. South Korea army needs at least 8 years to deploy link-22. But Japan, Israel, Singapore do not want to waste time and huge money on link-22 implementation since it does not have a big benefit on it. ** If Taiwan starts to deploy Link-22, it may need 10 years to achieve it around year 2035 ~ 2040 since it has to integrate with the "New F-16 C/D block 70, 66x units" as the final goal (delivered after year 2026). Taiwan so called home-made combat gears are not able to tag with Link-22 (unless a huge integration efforts & money spent). And more, it has to subscribe with " very expensive" - Military Grade satellite service provided by US Government to enable "secured data link tunnel as backbone service" to connect with edge devices - F-16 C/D block 70, La Fayette-class frigate, and new modern Navy vessels (US Made) if Taiwan has. USS KIDD old vessels are not able to connect with Link-22 since there is no refurbished work for it. Hanwha Systems will begin developing Link-22, tactical data links being introduced by North Atlantic Treaty Organization (NATO) member countries such as the United States and the United Kingdom. Link-22 aims to respond to future network-centric warfare (NCW) and strengthen Korea-U.S. combined operation capabilities. Hanwha Systems announced on Dec. 20 that it has signed a contract worth about 209.5 billion won with the Defense Acquisition Program Administration (DAPA) to develop 16 types of combined maritime tactical data link (Link-22) vessels and land systems. A maritime tactical data link is a digital communication network through which soldiers share and disseminate target information detected by surface ships, submarines and aircraft at sea, underwater and in the air in real time. Hanwha Systems will develop a data link processor and network control software, which are the core components of Link-22. It will also install and configure allied encryption equipment, modems and communication equipment and integrate them with combat management systems of vessels and land command posts through Link-22. The company will start the development of Link-22 for the Korean Naval Operation Command, the Korean Fleet Command and the Korean Naval Education & Training Command, escort ships, destroyers, submarines and support ships in 2023. It aims to complete mass production of tactical data links by 2029. Hanwha Systems supplies all combat management systems (CMSs) for various surface and underwater ships such as high-speed battleships, large amphibious support ships, training ships, destroyers, frigates, and submarines of the Korean Navy and has excellent ship standardization and modular design capabilities.
