U.S. military experience has shown that rugged terrain and threats such as ambushes and Improvised Explosive Devices (IEDs) can make ground-based transportation to and from the front lines a dangerous challenge. Combat outposts require on average 100,000 pounds of material a week, and high elevation and impassable mountain roads often restrict access. Helicopters are one solution, but the supply of available helicopters can’t meet the demand for their services, which cover diverse operational needs including resupply, tactical insertion and extraction, and casualty evacuation.

As commercial technologies become more advanced and widely available, adversaries are rapidly developing capabilities that put our forces at risk. To counter these threats, the U.S. military is developing systems-of-systems concepts in which networks of manned and unmanned platforms, weapons, sensors, and electronic warfare systems interact over robust satellite and tactical communications links. These approaches offer flexible and powerful options to the warfighter, but the complexity introduced by the increase in the number of employment alternatives creates a battle management challenge. Current battle management systems often lack the benefit of automated aids to help comprehend and adapt to dynamic situations.

For generations, new designs for vertical takeoff and landing aircraft have remained unable to increase top speed without sacrificing range, efficiency or the ability to do useful work. DARPA’s VTOL Experimental Plane (VTOL X-Plane) program seeks to overcome these challenges through innovative cross-pollination between the fixed-wing and rotary-wing worlds, to enable radical improvements in vertical and cruise flight capabilities. In an important step toward that goal, DARPA has awarded prime contracts for Phase 1 of VTOL X-Plane to four companies:

Cost and complexity limit the number of ships and weapon systems the Navy can support in forward operating areas. A natural response is to offset these costs and risks with unmanned and distributed systems. But how do such systems get there in the first place?

Reliable wireless communications today requires careful allocation of specific portions of the electromagnetic spectrum to individual radio networks. While pre-allocating spectrum is effective in benign environments, radios remain vulnerable to inadvertent interference from other emitters and intentional jamming by adversaries.
