Gun crew of Myanmar Army SH-1 155 mm howitzer inputting target's azimuth data into the automatic fire control system computer which can calculate the trajectory of the artillery and automatically lay the gun.
SH 1 is a 155 mm/52 calibre wheeled self-propelled artillery system developed by China North Industries Group Corporation (NORINCO). It is also considered one of the best among wheeled self-propelled artillery systems.
Being a wheeled self-propelled howitzer, SH 1 is easy to produce and maintain but as capable as tracked artillery system. However it is much more mobile than the towed howitzers and thus well suited for mountainous regions of Myanmar.
That is the main reason why Myanmar bought large number of SH 1 howitzers in early 2010s. Currently there are as many as 72 SH 1 howitzers in Myanmar inventory and they are used extensively in many counter insurgency operations.
Since 2015, SH 1s were spotted in many occasions including the Armed Forces Day patade.
SH 1 can fire a range of ammunitions, including: Extended-Range, Full-Bore, Rocket-Assisted, High-Explosive (ERFB-RA/HE) and Extended-Range Full-Bore, Base-Bleed, High-Explosive (ERFB-BB/HE).
When using the ERFB-BB/HE round, the howitzer can reach a maximum range of 53km.
SH 1 is only in service in Myanmar, China and Pakistan.
