IAI's ELTA Systems business has announced the release of the ARC 840 Software Defined Radio – Network Centric Operations (SDR-NCO) system.
This airborne communications system provides voice, video and data traffic over a frequency range including VHF, UHF and L-bands. It is designed to be interoperable with existing military and commercial radios, allowing aircrews to communicate with each other and across a multi-domain task force.
SDR-NCO can also support network applications such as C2, navigation or video sharing, and is compliant with the SCA 4.1 standard set by the Joint Tactical Networking Center,

SDR-NCO offers secure communications, implementing COMSEC, TRANSEC frequency-hopping support and LPI (low probability of intercept) techniques, as well as multi-standard GNSS with a Rubidium clock for backup.
The system comprises two user-swappable RF modules, allowing customised frequency band combinations for a given mission.
The two uncrewed fighter aircraft will be made in conjunction with Baykar, which joined forces with Leonardo under LBA Systems in June 2025 to develop and produce uncrewed aerial systems for the international market.
The startup was the only UK company to take part in the first Gauntlet for the programme, joining forces with its Ukraine partner to participate in the event.
The new entity incorporates crewed and uncrewed capabilities to tackle a variety of mission demands in both defence and commercial markets.
The strategy, schedule and budget to support Washington’s intention to speed up the manufacturing of defence capabilities remain unclear.
The reduction in the number of planned F-35A aircraft from 36 to 30 by the Swiss government comes due to budget constraints, with no firm plans to fill the gap despite “negative consequences”.
The USAF plans to phase out its 162 in-operation A-10 Thunderbolt II Warthogs by the end of FY2026, replacing them with F-35As which will bring a leap in capabilities in terms of lethality, survivability and speed.
