The first version, termed an "approximation" was tested by the 1948.

However, this version has not yet been successfully tested outside, although it performs well indoors.

In 1971 a version of A-35 was tested with the main command centre, one radar and three battle stations.

A second version was tested in 1965 with three flights, of which two failed.

An improved version, the Sejjil-2, was tested on 20 May 2009.

Sun said the new version had been tested by 140,000 volunteer users since November.

Different versions of the Tornado with various weapons were tested.

Both the 17-item version and the 10-item version were tested.

Various versions of the Champ have been tested and produced since 1944.

But is that the case, or were those versions not tested?
