US Army officials are soliciting industry feedback on the service's technology development strategy to revamp its Terrestrial Transmission Line of Sight (TRILOS) communications equipment, with plans to acquire two to three new TRILOS variants beginning in fiscal year (FY) 2026.

Led by Program Manager Tactical Network (PM TN), the 3 May request for information (RFI) will inform development of the new TRILOS variants.

The variants will feature a radio frequency (RF) base system, “with modular extensions incorporating Free Space Optics (FSO)” to connect with aerial tier assets via a “variable height, mast type configuration”, the 3 May RFI stated. Army officials plan to acquire over 700 modernised TRILOS systems.

China's Poly Technologies has displayed a new multimission-capable large unmanned underwater vehicle (LUUV) at the Defence Services Asia (DSA) 2024 exhibition held in Kuala Lumpur.

According to the company, the LUUV – named UUV300CB – can undertake missions including intelligence, surveillance, and reconnaissance and minelaying operations.

A Poly Technologies official told Janes that the UUV300CB is in development phase and that several variants of the platform could be produced by the company.

A cutaway model of the platform displayed at DSA 2024 shows torpedo tubes, a belly bay for loading EM12-500/1000 mines or UUVs, an image intelligence and reconnaissance mast, an electromagnetic intelligence and reconnaissance mast, sonar systems, and a covered vertical launcher for small missiles in its rear.

Other capabilities include satellite/ultra-high frequency communication and low acoustic signature.

US Special Operations Command's (USSOCOM's) electronic warfare (EW) Family of Systems (FoS) is the “newest” programme in the Program Executive Office (PEO) – SOF Warrior portfolio and was initially approved in November 2023 to focus on the “ground domain” operations, the command announced on 7 May.

SOF Warrior documents stated the EW FoS will include “dismounted/body-worn; mounted; unattended sensor; and small unmanned payloads to enable electromagnetic surveillance (ES), electromagnetic attack (EA), and electromagnetic protection (EP) capabilities”. The documents were presented at Special Operations Forces (SOF) Week 2024 in Tampa, Florida.

Officials suggested aspects of EP would be “pertinent” to countering unmanned aircraft systems as well as electromagnetic countermeasures (ECM). Other areas of interest include jamming-resilient radar capabilities.
