On 21 May 2007, the Finnish Yleisradio revealed some problems with the 155 GH 52 APU, dealing with reliability issues of the towing system and barrel behavior when firing long-distance rounds.

The arms deal lead into a juridical process formally presented as an allegation of corruption.

Inspector Janne Järvinen and state prosecutor Ari-Pekka Koivisto investigated if the 10% trade commission had been partly allocated to the directors of the buying organisation using the commercial agent.

The gun's deployment power is 78 kW and its driven speed (in terrain, to location) is 7.5 km/h or 15 km/h when pulled by a heavy truck.

After having encountered problems with firing at 35 km – 40 km, the Finnish Army concentrated its artillery gun development on the M270 Multiple Launch Rocket System (in Finnish arsenal 298 RsRakH 06, later 298 RSRAKH 06) bought as Dutch surplus.

It is a turreted variant of the cannon which is installed on a T-55 tank chassis, and was developed to be exported to Egypt.
