Bionix IFV

The Bionix (BX) is a family of tracked Singaporean armoured fighting vehicles developed by Singapore Technologies Kinetics (formerly Singapore Technologies Automotive, which is now known as Singapore Technologies Engineering). Intended to augment the Singapore Army's aging M113 armoured personnel carriers, it is the first indigenous armoured vehicle to be developed in Southeast Asia. The Bionix has been operational with the Singapore Armed Forces (SAF) since 1999 in a wide variety of adaptations including the Bionix II, Bionix 25 and Bionix 40/50 variants.

Protection

The hull and turret are of all-welded-steel construction with modular passive armour protection. Additional armour protection can be installed with an add-on layer of spaced passive armour.

Engine

The Bionix is a compact design produced to meet the conditions of Pacific rim countries where small size is a great asset when it comes to travelling among rubber plantations and over roads and bridges not designed for heavy vehicles. 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. Future upgrades in power ratings can be developed according to needs.

The integrated power pack is mounted to the right of the vehicle and can be removed from the Bionix as a complete unit in under 15 minutes. The engine is coupled to the L-3 Combat Propulsion Systems HMPT-500EC fully hydro mechanical transmission, with the final drives being provided by David Brown Defence Systems. The engine compartment is also fitted with an automatic fire detection and dry-powder fire suppression system with a supplementary manual back up.

Interior

The layout of the Bionix is conventional with the driver at the front left, the power pack situated at the front right and the turret in the center with the troop compartment at the rear. Access to the troop compartment at the rear of the vehicle is by a power-operated ramp, which can operate as an emergency access and exit door. A single hatch is installed over the troop compartment.

The driver enters via a roof hatch that opens to the left rear. When driving closed-down, observation is via three day periscopes, while the center periscope can be rapidly replaced by an image-intensification periscope for driving at night. 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 instrument panel is mounted on the left, with the transmission selection box on the right.

In the turret, the gunner's station is on the right and the commander's station is on the left, each with a single hatch cover. The turret traverses through 360°. Traverse and weapon elevation is by all-electric digital control. Both the gunner and commander have a turret stop button and are able to lay and fire the weapons. The gunner has the turret control box mounted to the right of his position and both turret-crew members have an adjustable seat. The communications equipment is installed in the turret bustle.

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

Aiming

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. The commander has an optical relay from the gunner's sight and a single control handle. The vehicle commander has a further five day periscopes to give observation to the turret front, left side and rear; the gunner has three periscopes (1 x M17 and 2 x L794D) to give observation to the right and rear.
