Integration of New Technologies
While Link-16 is widely adopted, the U.S. military acknowledges the need for higher data transfer rates, which Link-16 cannot provide. To address this, laser communications are being explored as a complementary technology. These systems offer low latency and high data rates, essential for future operations requiring rapid data transmission across various platforms. Thousands of laser communication terminals are expected to be deployed in the coming years, enhancing the capabilities of existing Link-16 networks. [Source]
Defense Partnerships and Strategic Initiatives
The U.S. Space Development Agency (SDA) is advancing the Proliferated Warfighter Space Architecture (PWSA), which will deploy hundreds of satellites in phases. These satellites will provide beyond line-of-sight targeting and missile tracking capabilities, with Link-16 remaining integral to the system. The SDA’s strategic objective is to minimize changes to existing user equipment, ensuring compatibility with legacy radios and preventing the need for widespread replacements. [Source]
