The Bionix (BX) is a family of tracked Singaporean armoured fighting vehicles developed by ST Engineering Land Systems.

[5] With the growth and development of the Singapore Armed Forces (SAF) during the mid 1980s came a need to bolster of the existing fleet of M113 Armored Personnel Carriers .

With the participation of the SAF, the Defence Materiel Organisation , MINDEF's systems acquisition house, was appointed to conduct a technology study and recommend the direction for the project.

Key considerations during the design process included high mobility and agility, low weight, amphibious capability, and adequate protection and firepower.

The power provided by the 475 hp (354 kW) Detroit Diesel engine to drive its 23 tonnes, ensures the Bionix is able to overcome the most difficult terrain.

The driver guides the vehicle using a small steering wheel rather than tillers and, as an automatic transmission is fitted, there are just two pedals - accelerator and brake.

The basic production models lacks an in-built air conditioning and NBC protection system, but can be fitted if/when needed.

The gunner has a twin-control handles and a day/thermal sight, with a magnification of x8 and two fields of view (high and low), with stadias for the 25mm cannon and 7.62mm coaxial machine gun.
