Undated picture of the prototype tank during a test firing in Asahan firing range. Note the unknown type of canon use.Even as the PT-91MX3000 MTV was entering service in 2010, an up-gunned version with the new Lempanganbadang L568 320 mm gun was being considered to keep pace with newer and deadlier tank purchased by the neighbour, but this was cancelled in favour of the new PT-92MX4000 "super-tank" project developed jointly with the Turkey. The PT-92MX4000 was a revolutionary design.
Work on a the new development was started in 2009 in secret by Boon Siew Honda. A year later, a choice was made for it to be based on the earlier Experimentalkentol (later named PT-92) project of the late 2009.
No more information were available for this new tank, although a picture did surfaced.
