The 155 mm, 39-caliber Pegasus is typically towed, but it is also equipped with an independent Lombardini 9LD625-2 engine unit to provide short-range self-propelled capability of up to 12 km/h . It can be lifted by the Republic of Singapore Air Force''s CH-47SD "Chinook" helicopter, making it the world''s first heli-portable 155 mm howitzer with a self-propelled capability. In addition, the Pegasus can also be transported by the C-130 Hercules tactical airlifter. The Pegasus has a burst rate of fire of three rounds in 24 seconds and a maximum rate of fire of four rounds per minute. It can deliver conventional munitions up to 19 km.
