New Signals Intelligence Platforms for Republic of Korea Air Force

The Republic of Korea Air Force (ROKAF) could spend up to $725 million on new SIGINT aircraft between now and 2026.

Plans were approved by Republic of Korea’s Defence Project Promotion Committee (DPPC) on 26th June to acquire new Signals Intelligence (SIGINT) platforms for the ROKAF with a budget of $725 million.

The ROKAF uses two Dassault Falcon-2000S and four BAE Systems Hawker RC-800 SIGINT gathering aircraft. The Falcon-2000S jets were delivered in 2017. The RC-800 aircraft are slightly older, entering service in the early 2000s. DPPC plans call for four of the RC-800s to be replaced with the new SIGINT acquisition.

Wavebands

Both the Falcon-2000S and RC-800s are believed to gather Communications Intelligence (COMINT) and Electronic Intelligence (ELINT) at the operational, and possibly strategic, levels. To this end, they are thought to collect COMINT/ELINT across 500 megahertz to 40 gigahertz wavebands. This intelligence maybe analysed onboard by electronic warfare specialists and/or transmitted across air-to-ground datalinks.

It is reasonable to assume that the ROKAF may choose to procure at least four new aircraft to replace the same number of RC-800s. The force could spend up to $175 million on each aircraft with a residual $25 million covering training and other ancillary costs. Local reports state that the first new SIGINT aircraft could enter service in 2026.
