hybrid airship
A hybrid airship or plimp is a powered aircraft that obtains some of its lift as a lighter-than-air (LTA) airship and some from aerodynamic lift as a heavier-than-air aerodyne.

to one of its implementations of the SkyCat design. These are proposed to carry heavy-lift and ultra-heavy-lift cargo payloads from 50 tons net payload to as heavy as 1000 tons which may be a mix of outsized and/or containerized objects.
The Skycat is almost impervious to light ordnance, such as automatic rifle or mortar fire, which will merely pass through the metallized
PET film envelope without causing critical helium loss.
SkyCat air vehicle developments are being pursued by at least one major aerospace company.

ATG went into administration in 2005 having produced only one airship, the SkyCat. SkyCat Group was formed and bought ATG's operations. In turn Hybrid Air Vehicles of the UK was formed acquiring the assets of SkyCat Group in 2007 to continue development of the concept.
