J-20 No. 2011

The latest example of the stealthy Chengdu J-20 fighter has recently undergone high-speed taxi testing at the company airfield, suggesting that a first flight is imminent, possibly scheduled for this weekend. Thought to be the third flying example of the J-20, the new aircraft is being considered as a true developmental airframe for an operational fighter, and has introduced a number of significant improvements over the two technology demonstrators that preceded it. Many of the changes are measures taken to reduce the type’s radar cross section.

Raytheon has warned against overreliance on stealthy platforms alone in future air combat. Despite their low radar cross-sections (RCS), fifth-generation fighters such as the F-35 can be detected by modern air defense systems. To defeat these defenses, air forces should take full advantage of the latest sensors and weapons that can be carried on less stealthy aircraft, the company said.

The U.S. Air Force F-15 display here is so hot you can see the paint peeling off the aircraft! In fact, although this F-15E Strike Eagle needs sprucing up a tad, its airshow act could hardly be smarter. The display put on by captains Phil “Ritz” Smith (pilot) accompanied by John “Gizmo” Cox in the back seat, is the best that AIN has seen of an F-15.

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.
