Things You May Not Know About SLWH

The Singapore Light Weight Howitzer (SLWH) Pegasus is a helicopter-transportable, towed artillery piece. Developed jointly by the Singapore Armed Forces (SAF), Defence Science and Technology Agency (DSTA) and Singapore Technologies Kinetics, it was commissioned on 28 October 2005. The Singapore Army conducted its first live firing of the SLWH Pegasus at the artillery range of Waiouru Army Camp in New Zealand as part of Exercise Thunder Warrior in January 2006.

Here, we share with you other facts you may not know about this asset!

SLWH heli

1. It can fly, with the help of others.

The SLWH is the world’s first heli-portable 155mm howitzer with self-propelled capability, allowing it to ‘fly’ when being attached to a helicopter. However, it does not bear air capabilities and is typically towed. 

With an Auxiliary Power Unit (APU), an independent engine unit on the SLWH, it provides the gun with a short range self-propelled capability, allowing it to manoeuvre over terrain at a speed of 12 km/h. 

2. It can fire multiple shots in a short span of time

Powered by the APU, the Ammunition Loading System (ALS) automatically loads ammunition to reduce crew fatigue. This allows the gun crew to operate the SLWH for a longer period while ensuring a burst rate of three rounds in 24 seconds.

3. It can be deployed within 2.5 minutes.

The SLWH is easy to configure without any lifting support in the field. Through a simple seesaw action that shifts the gun’s centre of gravity to suit the different missions, the SLWH can be rapidly deployed in less than 2.5 minutes with a detachment of eight soldiers. This allows the SLWH to be deployed quickly and efficiently. 

4. The recoil is much lower than usual howitzers.

The recoil of the SLWH is one-third lesser than conventional 155mm howitzers, thanks to its innovative recoil management design. It employs lightweight materials such as titanium and high alloy aluminium to provide the strength and stability to withstand the recoil force. Each gun is also able to withstand firing shocks of up to 90Gs. 

With it being a highly automated system that can achieve a range and firepower comparable to heavier systems such as the FH88 and the Primus, the SLWH indeed provides versatility and firepower!
