Vickers Armstrong also developed a SPAGG based on the chassis of the Mk. E 6-ton light tank / Dragon Medium Mark IV tractor, mounting a Vickers QF-1 " Pom-Pom " gun of 40 mm.

About 26 were sold to Siam and saw action as Infantry support guns and AA guns during the Franco-Thai war ( 1940-1941 ) along with 30 Vickers Mk. E Type B 6-ton tanks.

This was probably the first tracked SPAAG manufactured in series.

Later the British also developed a version of the Mk. VI light tank armed with 4 machine guns that was known as Light Tank AA Mk. I.

And also a twin 15 mm version based on the Light Tank Mk. V was built.
