This Swiss improved version produced by [[RUAG]] incorporates a new Swiss-designed L47 155&nbsp;mm gun with an increased firing range of up to 36&nbsp;km. It features an [[inertial navigation system]] coupled with a new gun-laying system, along with an ammunition storage increase of 40 rounds and 64 charges. The KAWEST (lit. ''Kampfwertsteigerung'' = upgrade of combat capabilities) requires only six crew members instead of eight. It is able to fire three-round bursts within 15 seconds, or maintain a constant firing rate of over one round per minute.<ref name = 'RUAG'>{{cite web|title = M109|website = ruag.com|url = https://www.ruag.com/en/products-services/land/vehicles-weapon-systems/indirect-fire-artillery/m109|access-date = 9 May 2018|archive-url = https://web.archive.org/web/20180709193055/https://www.ruag.com/en/products-services/land/vehicles-weapon-systems/indirect-fire-artillery/m109|archive-date = 9 July 2018|url-status = live}}</ref><ref name = 'Chile'>{{cite web|title = Chile Requests a Mechanized Artillery Battalion|website = Defense Industry Daily|url = https://www.defenseindustrydaily.com/Chile-Requests-a-Mechanized-Artillery-Battalion-05515/|date = 6 October 2011|access-date = 9 May 2018|archive-url = https://web.archive.org/web/20180509220622/https://www.defenseindustrydaily.com/Chile-Requests-a-Mechanized-Artillery-Battalion-05515/|archive-date = 9 May 2018|url-status = live}}</ref>
