The stealthy, jet-powered version of the Predator series UAV that was unveiled last month was developed “with significant company investment,” according to General Atomics Aeronautical Systems Inc. (GA-ASI). Tom Cassidy, president of GA-ASI’s aircraft systems group, again sought to contrast the company’s lean and independent development model with that of the major aerospace companies.

One of the biggest problems for those designing the next generation of unmanned combat air vehicles (UCAVs) is how to define, choose and incorporate a powerplant. Rolls-Royce believes it has the answer in a new type of engine system that has a much hotter core and provides not only power to the airframe, but also manages the entire power requirement of the UCAV. However, it doesn’t have the money for the program–at least, not yet.

While European governments preach greater collaboration in defense research and development, three competing programs for uninhabited combat air vehicles (UCAVs) have been officially funded. Yet the aim of all three is to preserve the European high-technology base and develop important capabilities such as low-observability and autonomous control, independent of the U.S.

Japan’s defense budget for Fiscal Year 2008 includes only Y7 billion ($66 million) for the Mitsubishi ATD-X Shin-shin (Spirit) new-technology fighter demonstrator. The amount is considerably less than the Y49.9 billion ($462 million) requested by the organization overseeing the program, the Technical Research and Development Institute.

Brian Kilburn of the Boeing B-2 System Program Office presented insights into the true cost of a stealth operation at the Stealth Conference conducted recently in London by military/defense conference organizer Defence IQ. Kilburn noted that the 20-strong fleet of B-2s requires 70,000 maintenance hours annually, and that 40 low-observable (LO) technicians work on them full-time. The U.S.

Four decades after the first truly stealthy air vehicles were secretly flown in the U.S., the technology has matured and proliferated. Many countries could now design a stealthy, small unmanned aerial vehicle, but since uncompromised stealth capabilities bring penalties, developers and operators are still wrestling with multiple trade-offs.
