The Canadian Vickers Varuna was a Canadian flying boat of the 1920s built by Canadian Vickers as a twin-engined, unequal-span biplane, with a wooden hull and steel tube structure.

Design and development[edit]

The Varuna was developed in response to a Royal Canadian Air Force requirement for a flying boat to transport men and equipment to forest fires. It was a large-scale twin-engined version of the Vedette.

Operational history[edit]

Most Varunas spent their service in Manitoba operating in their intended role; all Varuna IIs were withdrawn in 1930 and the sole Varuna I was struck off in 1932

  1. Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
