ST Engineering's history began with its precursor, the Chartered Industries of Singapore, which was established in 1967 by the newly independent Singaporean government as an ammunition manufacturer. Businesses related to aerospace and shipbuilding were later created and put under the ST umbrella. The ST group of companies went commercial in 1990, setting up its first commercial airframe manufacturing, repair and overhaul facilities in Singapore and the United States. ST Engineering was created in December 1997 as a merger of four listed companies: ST Aerospace, ST Electronics, ST Automative and ST Marine. Its shares debuted on the Singapore Exchange on 8 December 1997.^[7][8]

Since then, ST Engineering has grown to become one of Asia's largest defence and engineering groups for commercial and defence organisations across multiple industries.^[9] In Mar 2007, ST Engineering was ranked 19th in the aerospace & defence industry and 1,661th of 2,000 of the world's largest public companies by Forbes.^[10]

ST Engineering is a major player in the defence and military industries. It was ranked Number 61 in the Stockholm International Peace Research Institute's list of the world's top 100 defence manufacturers in 2021.^[11] Outside of Singapore, it has sold defence products to over 100 countries,^[12] including United States, United Kingdom, Indonesia, Philippines, United Arab Emirates, Brazil, Sweden, India, Thailand and Finland.^[13] ST Engineering do not design, produce or sell anti-personnel mines, cluster munitions, white phosphorus munitions and its related key components.^[14]

In 2018, the Group harmonised all brands by using "ST Engineering" as a Masterbrand^[15] while in 2020, the Group reorganised as Commercial and Defence & Public Security clusters,^[16] replacing the sector-structure of Aerospace, Electronics, Land Systems and Marine. ST Engineering's network of subsidiaries and associated companies spans across the Americas, Asia, Europe and the Middle East.^[17]

ST Engineering expanded to the United States in 2001, locating its U.S. headquarters in Herndon, Virginia. It operates in 50 cities across 23 states. It was known as VT Systems (VTS; formerly known as Vision Technologies Systems) until 1 July 2019, when VTS was changed to ST Engineering North America as part of the Group’s brand harmonization exercise in 2018.^[18]

As of 28 February 2022, Temasek Holdings has a 51.69% shares in ST Engineering.^[19]

In 2014, ST Engineering and its subsidiaries ST Engineering Marine and ST Engineering Aerospace were hit by one of the largest corruption scandals in Singapore history following investigations by the Corrupt Practices Investigation Bureau.^[43][44][45]

In December 2014, former ST Engineering Marine and ST Engineering Aerospace president, Chang Cheow Teck, was charged with conspiring with two subordinates to offer bribes in return for ship-repair contracts between 2004 and 2010.^[46] The corruption charges were eventually withdrawn and in January 2017, Chang pleaded guilty to "failing to use reasonable diligence in performing his duties" and was given a short detention order of 14 days.^[43] Former ST Marine CEO and president See Leong Teck was also charged with seven counts of corruption.^[46] In December 2016, See was sentenced to 10 months' jail and a $100,000 fine.^[44]
