In response to the requests from many of Rockwell Collins customers, Collins is pleased to announce the Rubicon II Advanced C²W/IW system. This basic VME based C²W system offers enhanced functionality compared to the Rubicon-I in an easily expandable, open architecture VME 64x modular format. This modular format allows for scalability to meet simple or complex missions on various platforms.

The Collins Rubicon II Electronic Warfare System is a high-performance, state-of-the-art electronic attack system that is designed for precision jamming of multiple simultaneous fixed-frequency and advanced emitters to deny the enemy the use of radio communications throughout the battle space. The system includes the EWSP-2500 - an eighteen-slot VME chassis consisting of VME-64X modules that perform various EW functions. The standard system consists of two CV-2800 RF-IF translators, two NBT-70 Narrowband Tuners, a WFG-70 Waveform Generator, a AMU-2500 RF Multicoupler, a PIU-2500 Transmit Interface, a frequency reference, and a general-purpose VME processor. The system is capable of reactive, preemptive, and manual jamming modes for specified target frequencies and electronic support modes for the acquisition of new targets. Proven, mature software algorithms provide dependable and robust system operation. The system is normally connected to a laptop control computer, power amplifiers, and antennas that are chosen for the platform and application.

In all ES and EA modes, the system provides communications monitoring or jamming capability against single-channel fixed-frequency communications in the high frequency (HF), very high frequency (VHF), and ultra high frequency (UHF) bands. When not used for C²W modes, the system can be operated as a standard radio for conventional AM/FM/SSB communications within its frequency range. The system has built-in test capabilities that isolate faults to an industrial VME module. The entire system is embedded in a single VME ruggedized chassis with the exception of the P.A. and work station.

The system is fully operable by one operator using the Windows software application that is installed onto the laptop computer or other suitable host workstation. Auxiliary control, audio, and RF inputs and outputs of the system are all accessible from the outside of the VME chassis.
