AN/ARC-210 Gen5 Programmable Digital Communication System

The Rockwell Collins RT-1990A (C) (ARC-210 Generation5) is the most advanced Receiver-Transmitter (RT) in our proven ARC-210 communication system family. We have supplied more than 30,000 AN/ARC-210 radios worldwide on over 180 platforms, making them the accepted choice for multiband, multimode communications. Specifically, the RT-1990A (C) has been redesigned to better meet your needs and conform to Software Defined Radio (SDR) tenets and architectures. RT-1990A (C) provides superior performance in the transfer of networked or point-to-point data, voice and imagery. An additional connector has been added in the back of the radio to allow an Ethernet input.

In response to the world’s constantly evolving transmission and communication security needs and to comply with the National Security Agency’s (NSA) Cryptographic Modernization Initiative, the RT-1990A (C) is the first military airborne transceiver to provide an embedded, fully programmable INFOSEC capability.
