Why the RF is Concerned
Mission
The RC-135U Combat Sent provides strategic electronic reconnaissance information to the president, secretary of defense, Department of Defense leaders, and theater commanders. Locating and identifying foreign military land, naval and airborne radar signals, the Combat Sent collects and minutely examines each system, providing strategic analysis for warfighters. Collected data is also stored for further analysis by the joint warfighting and intelligence communities. The Combat Sent deploys worldwide and is employed in peacetime and contingency operations.
There are only two Combat Sent aircraft in the Air Force inventory and both are assigned to the 55th Wing at Offutt AFB, Neb. The RC-135U aircraft are manned by Air Combat Command crews from the 45th Reconnaissance Squadron and the 97th Intelligence Squadron (of the Air Force Intelligence, Surveillance and Reconnaissance Agency). The Combat Sent is composed of a wide variety of commercial off-the-shelf and proprietary hardware and software. Its current configuration allows for both manual and automatic analysis of electronic signals. By combining manual systems with the Automatic Electronic Emitter Locating System, Ravens and intelligence specialists can simultaneously locate, identify, and analyze multiple electronic signals.
All RC-135U aircraft are equipped with an aerial refueling system, giving it an unlimited flying range. Communication equipment includes high frequency, very high frequency, and ultra high frequency radios. The navigation equipment incorporates ground navigation radar, a solid state Doppler system, and an inertial navigation system that merges celestial observations and Global Positioning System data. Although the flight crew stations are similarly configured, the reconnaissance equipment is slightly unique within each airframe.
The Combat Sent records these signals for future reference or for extensive analysis by electronic systems theorists. Any information garnered from the data will help determine detailed operating characteristics and capabilities of foreign systems. Evasion techniques and equipment are then developed from this knowledge that will detect, warn of, or defeat these electronic systems.
The RF is trying to counter our ABMS, and we needed their evasion techniques, detailed operational characteristics, etc of what nukes they just placed in Crimea and Kalingrad. Since it merges celestial and GPS and operated in HF and Ultra HF, they surely got close enough to accomplish the mission.
Notice the Combat designation because this goes straight to the President, SECDEF the people authorized to launch. Russia knows this. Probably scared em a wee bit, don't ya think?
Russia has now been severely probed and now we have the specs on what we are dealing with. Perhaps the most provocative move yet by the US. Interested to see the RFs response to this one.
