The decision to surrender control of the CSeries to Airbus represents the final stage of a 12-year long slow-motion story that’s best described as a noble and heroic farce. Bombardier, Canada, and Quebec bit off way more than they could chew. Poor management and decision-making compounded this reality. Once Airbus and Boeing re-engined and upgraded their single-aisle models (as a reaction), the CSeries didn’t stand much of a chance. Since the CSeries began in 2006 and through the decision to surrender, Airbus and Boeing racked up 17,264 single aisle jetliner orders (8,104 Boeing, 9,160 Airbus). The CSeries got 360.

The Uninhabited Combat Air Vehicle (UCAV) is the most futuristic application for UAVs, and has seen considerable turmoil over the past decade, while the services thrashed out what they expected from the program. DARPA headed the original program, followed by a DoD consolidation, only to see DoD again break up the program with the Navy pursuing the carrier-based J-UCAS and the Air Force effort disappearing "into the black".

The Navy program seems to have ended in 2016 with the shift from the UCLASS strike/ISR to the CBARS aerial refueling system. However, it is also possible that the Navy has shifted its stealth/strike UAS "into the black”.

In September 2018, the US Army awarded competitive contracts to Thales Defense and Harris Radio Corporation, for procurement of the 2-Channel Leader Radio, to support the Army’s Network Modernization strategy, Security Force Assistance Brigade communication needs, and Network Cross-Functional Team experimentation efforts with a software-defined radio capable of providing data and voice communications via multiple waveforms. With the 2-Channel Leader Radio, soldiers will only carry one radio instead of the two currently required for voice and data. Thales’ Leader Radio is its AN/PRC-148C (IMBITR), embedding the TrellisWare TSMTM waveform.

Signals Intelligence (SIGINT) programs tend to be among the most classified programs in the U.S. and other militaries. While bits of information often become available – especially RFPs – comprehensive program information and funding tend to remain secret. It is certain that many small, probably inexpensive SIGINT sensors are currently flying aboard small UAVs, but comprehensive information is not available publicly.
