Sisu Auto introduced a new series of military designated lorries based on Sisu E-series in 1997, using components supplied by Renault. This series consisted of 6×6- and 8×8-driven vehicles. This led to the re-establishment of Sisu Defence in 2005 as a part of Sisu Auto. A notable milestone was a contract of armoured Sisu E13TP 8×8 vehicles to the Lithuanian Armed Forces. A series of new light lorries Sisu A2045 was produced in 2009–2010 to replace the aged KB-45 and A-45 models.
