between 2012 and 2021. In September 2010, the Board of Audit and Inspection claimed that the Army was biased during evaluation, and demanded re-analysis of the project regarding inefficiency of the system. The Defense Acquisition Program Administration (DAPA) ignored the Board and continued with the project while the Army purposely delayed complying. In June 2011, the Ministry of Defense again ordered a reexamination of the resupply vehicle. DAPA instead requested a budget for the program, and the development was completed in October 2011. In July 2013, the DAPA announced the 1st production batch of the K56 between 2013 and 2015 for 65 billion KRW. In December 2015, Hanwha Techwin signed a contract with the DAPA for a 2nd production batch. In January 2018, Hanwha Land Systems announced a 166.4 billion KRW contract with the DAPA for a 3rd production batch and related products. In June 2020, Hanwha Defense announced 380.3 billion KRW contract with the DAPA for a 4th production batch. South Korea plans a 5th production batch and to achieve full operational capability by 2025. All K56s were delivered to the western front. Training systems The US Army uses the Fire Support Combined Arms Tactical Trainer (FSCATT) in two versions, for initial and sustainment training of the M109A6 and M109A5. The system uses an actual surplus turret and a simulated ammunition system. The Swiss Army uses a highly advanced KAWEST trainer from Van Halteren Metaal of the Netherlands. The Dutch, Belgian, Thai, and Israeli Armies have various configurations of the Van Halteren Metaal M109 Howitzer Crew Trainer (HCT). The US Army PEO STRI had a program called M109A7 Howitzer Crew Trainer (HCT). The plan was to procure 16 systems beginning in the 3rd Quarter of FY 20. Successors The U.S. Army sought to replace the M109 with the XM2001 Crusader, initially part of the Armored Systems Modernization program. The program was canceled in 2002 amid criticism that the program was not in line with the Army's long-term plans for lighter armored brigades. Funding was redirected to the Future Combat Systems Manned Ground Vehicles program, which produced the 18-ton XM1203 Non-Line-of-Sight Cannon as the program's lead effort. The Pentagon terminated the MGV program in 2009 due to concerns over its affordability. The U.S. Army's M1299 howitzer was planned to be completed in 2021 and will undergo operational assessment in 2023. Operators Current operators M109 M109A1 : 10 : 17 :
