The goal of the Adaptable Lighter Than Air (ALTA) program is to develop and demonstrate a high altitude lighter-than-air vehicle capable of wind-borne navigation over extended ranges. The balloons can fly at altitudes of more than 75,000 feet.

In the decades-long quest to develop reusable aircraft that can reach hypersonic speeds – Mach 5 (approximately 3,300 miles per hour/5,300 kilometers per hour) and above – engineers have grappled with two intertwined, seemingly intractable challenges: The top speed of traditional jet-turbine engines maxes out at roughly Mach 2.5, while hypersonic engines such as scramjets cannot provide effective thrust at speeds much below Mach 3.5.

Difficult terrain and threats such as ambushes and Improvised Explosive Devices (IEDs) can make ground-based transportation to and from the front line a dangerous challenge. Helicopters can easily bypass those problems but present logistical challenges of their own, and can subject flight crew to different types of threats. They are also expensive to operate, and the supply of available helicopters cannot always meet the demand for their services, which cover diverse operational needs including resupply, fire-team insertion and extraction, and casualty evacuation.
Military aircraft have evolved to incorporate ever more automated capabilities, improving mission safety and success rates. Yet operators of even the most automated aircraft must still manage dauntingly complex interfaces and be prepared to respond effectively in emergencies and other unexpected situations that no amount of training can fully prepare one for.
The U.S. military’s investments in unmanned aircraft systems (UAS) have proven invaluable for missions ranging from intelligence, surveillance and reconnaissance (ISR) to tactical strike, but most current systems demand continuous control by a dedicated pilot and sensor operator supported by numerous telemetry-linked analysts.
