RM5 RUGGED HIGH-SPEED MODEM – 3 kHz
The RM5 Rugged High-Speed Modem is a MIL-STD-188-110A/B HF data modem, engineered with a rugged, field-hardened enclosure for use in the most demanding environments. Designed for disaster relief agencies, the RM5 provides standardised interoperability in harsh and unpredictable conditions. It is also an ideal choice for military and paramilitary organisations, ensuring robust performance when it matters most.
The RM5 supports various HF modem standards, including MIL-STD-188-110A and MIL-STD-188-110B, STANAG 4539, STANAG 4285, STANAG 4529 and STANAG 4415. It also offers optional second-generation automatic link establishment (2G ALE) according to MIL-STD-188-141B.
The RM5 can accommodate both narrowband data modems with a fixed 3 kHz bandwidth and wideband VHF data modems with bandwidths up to 24 kHz. It typically interfaces with rugged PCs or laptops via an Ethernet port, and the optional RC50 Email Software provides STANAG 5066-compliant ARQ email service.
Designed to meet the demands of critical operations, the RM5 is the definitive solution for ensuring reliable communication in the most challenging environments.

By adopting standardised HF/VHF technology, countries with shared maritime interests and security commitments can achieve self-reliance for naval and strategic communication. Reliance on satellites or fixed infrastructure exposes critical operations to significant vulnerabilities.
Interoperability between nations is of the utmost importance and can be achieved by fielding NATO-standardised products in HF/VHF core systems. RapidM has well-established relationships with integrators in countries such as Italy, Sweden, Denmark, Spain, the United Kingdom, and France, and major navies are successfully using our equipment.
We are actively working on various broadcast, ship-to-shore, and tactical HF standardisation profiles and can offer expert advice on HF core system requirements. We have supplied numerous prominent Tier 1 naval platforms with standardised products and solutions, allowing for drone-proof distribution of shore stations in diverse, dispersed locations. The combination of NATO BRE2TA (BRASS Enhancement 2 Technical Architecture), MELPe NATO Voice, and STANAG 4538 achieves tactical HF interoperability. Dynamic networked IP data communication in multi-node, multi-hop V/UHF Line-of-Sight (LOS) and HF Extended Line-of-Sight (ELOS) radio circuit networks is emerging with STANAG 4691 (MARLIN).
In addition, we provide tactical products and solutions that allow amphibious forces and partner forces to achieve interoperability with shore stations using equipment already fielded.
Our high-end data modems, ALE controllers and ARQ protocol units offer exceptional levels of performance. Our products also fully comply with emerging and relevant industry standards, including ISO, IEC, CE and interoperability standards such as MIL-STD-188-110B and 110C; MIL-STD-188-141B, 141C and 141D; and STANAG 4538, 4539, 4539/TDMA, 5066, and 4691.
Our RM, RC, and RI product families enable beyond line-of-sight (BLOS) communications, secure data exchange, and supports point-to-point communication, ship-to-shore communication, ground-to-air communication, and broadcast transmissions.
Our products integrate into 19-inch rack-mounted configurations at high-power NATO shore stations and mobile platforms, supporting BRASS, BRE1TA, and BRIPES operations.
RapidM’s naval and strategic product range provides reliable, long-range communication solutions for navies, coast guards, and commercial users, supporting various platforms and operations in both satellite and satellite-denied environments. Tactical data link platforms are supported, providing a communication backbone for both defence and commercial sectors.
