site was agreed at Karachi (now part of Pakistan since the
partition of the country in 1947) in . This was agreed to
be the one of the main "terminals" or junctions as part of
the Imperial Airship Communications scheme in 1926.

site was located outside Karachi and in 1927 the construction
of an airship mast, hydrogen plant and hanger began. The
Mast followed the same basic designs as the Cardington mast,
with the same height and construction method. The only exception
was that the base of the mast contained buildings followed
along the baseline in an octagonal shape. The airship base
also contained a hydrogen plant in order that the ships
can be regassed at the mast.
The gasometers contained enough gas to refill the R101,
at a capacity of 5.5 million cft of gas. A airship shed
was erected which was larger than the original Cardington
sheds and of a simpler design. This was decreed that the
slanting side areas were not needed as it was not to be
a constructional shed, and the sides of the hangers at Cardington
contained a lot of the offices and storage space during
construction of a ship.
The shed was also designed with the future in mind as it
was 850ft long , 170ft high and 180ft wide. This would have
fitted the new R102 class ship which was designed to be
some 822ft long. Construction of the facility cost some
£ 93,000 in 1928 ( £3,500,000 - 2002 prices).
The Shed and mast, although never used by an airship remained
erected until well after India's independence from Britain,
and later territory tansferred to Pakistan. The shed was
later dismantled and the steel was used for bridges and
other smaller buildings along the vast Pakistan Railways.
As with some of the other proposed sites, the Karachi site
is the location of the International Airport today.
