The U.S. State Department approved the sale of communications equipment worth over $350 million to South Korea and Belgium. This strategic decision aims to enhance secure battlefield connectivity among key allies. The sale to South Korea amounts to $200 million, while the one to Belgium reaches $156.1 million.

The primary goal is to secure communications in air and ground environments, ensuring interoperability with allied forces and strengthening the ability to respond to current and future threats.

The package for South Korea focuses on ARC-210 secure radios and KY-100M communication security devices. These devices will be installed on a wide range of aircraft, including fighter jets, transport planes, and helicopters. Platforms include F-15K fighters and CH-47 and UH-60 helicopters, reflecting an effort to standardize secure communications across the fleet.

Collins Aerospace will serve as the principal contractor. The systems are designed to provide secure SATURN communications, a NATO-standard waveform that enables jam-resistant, encrypted voice links.

The agreement with Belgium includes AN/PRC-series radios, tactical key loaders, and associated accessories, with L3Harris Technologies as the main supplier. Unlike South Korea's air upgrade, the Belgian acquisition focuses on ground forces, enabling secure communications over long distances and reducing the risk of interception.

This sale also supports interoperability within NATO operations, underscoring the importance of defense collaboration among allies.

In February 2024, the United States approved a $75 million sale to Taiwan for upgrades to the Advanced Tactical Data Link and related communications equipment. The aim is to improve the flow of secure information and interoperability for Taiwanese armed forces.

In October 2024, the State Department approved a proposed Foreign Military Sale of $1.42 billion to the Netherlands for radio equipment. It includes tactical and wideband radios, key loaders, network encryptors, and support services to enhance secure communications among Dutch forces.

In May 2025, the United States approved a Foreign Military Sale of $181 million to the Czech Republic for tactical radios, secure data links, and key loaders. This will modernize their communications infrastructure and improve NATO interoperability.

In January this year, the United States approved a Foreign Military Sale of $110 million to Iraq to expand the country's military satellite communications network. The package included Very Small Aperture Terminals, modems, hubs, and tactical satellite equipment to strengthen secure command and control capabilities.
