Rohde & Schwarz to Implement BRASS EO on Royal Danish Navy Ships

Equipping 12 ships, two coastal stations and a training facility


The Defence Acquisition and Logistics Organisation (DALO) of the Danish Ministry of Defence (MoD) awarded Rohde & Schwarz a procurement and maintenance contract for the implementation of NATO’s Broadcast and Ship Shore Enhancement One (BRASS EO) architecture for state-of-the-art HF communications (3-30 Megahertz/MHz).

The Danish Navy is the first user to implement the new NATO target architecture BRASS Enhancement One Target Architecture (BRE1TA) for HF communications within the fleet. In addition to procurement and installation of the system solution for twelve ships and three shore stations, the contract includes 15 years of maintenance, service and support.

We are pleased to continue our cooperation with Rohde & Schwarz as a reliable partner for our navy’s shortwave communications system,” Michael Tarp Hansen, Project Manager BRASS EO at DALO, said. “Having used the radios for many years, we were already confident in the technology. Now Rohde & Schwarz has offered us an attractive overall solution for the complicated system integration that fulfils Danish as well as NATO requirements for strategic HF communications.”

“We are proud to be the first supplier on the market to implement the new standard together with the Royal Dutch Navy,” Holger Brandt, Vice President Market Segment Navy at Rohde & Schwarz, continued. “We not only contribute our technological excellence and solution competence as a system integrator, we also assist and support our customers over the long term during the utilisation phase.”

BRE1TA offers simplified routing, resulting in faster transmission of military information between coastal stations and seagoing units in accordance with STANAG 4406; and IP services can be provided over shortwave links in accordance with STANAG 5066. Backward compatibility with NATO BRASS Initial Core Capability (ICC) and NATO legacy systems ensures interoperability with other branches of the armed forces and NATO units.

For robust and autonomous long-range communications (beyond line of sight), Rohde & Schwarz is equipping 12 ships (Absalon, Iver-Huitfeldt, Thetis & Knud Rasmussen Class), two coastal stations and a training facility.

The turnkey solution includes the message processing, remote supervisory and control, and communication infrastructure and switching subsystems.

The system is based on the R&S M3SR Series 4100 HF radios with new interfaces for wideband applications, the R&S MMHS message handling system, and other key components of the integrated R&S NAVICS communications system. Cybersecurity solutions conforming with the latest NATO information assurance standard are integrated into the IT infrastructure. The Rohde & Schwarz radio equipment also provides the basis for wideband HF applications (HF wideband) and higher data throughput on radiocommunications lines.
