Design
editThe hull of the Dragon Dream has a flattened elliptic cross-section.
Buoyancycontrol is managed by pumpingheliumgas from the internal gas bag and compressing it into a storage cell, the reduction in lifting volume leading to a loss of buoyancy. The system can vary the airship's lift by 3,000–4,000 lb. The manufacturer uses the phrase "Control Of Static Heaviness" for this technology.

Operational history
editThe airship was completed in 2013 and, after extensive systems tests in the construction hangar atMCAS Tustin,was granted anairworthiness certificateby the USFederal Aviation Administrationin September 2013, following which some outdoor tethered trials were carried out. Shortly afterwards it was badly damaged when part of the hangar roof collapsed,[6]and the company sued the US Navy for $65 million in 2015.[7]
