While in the process of incorporating the M142 HIMARS MLRS systems, the Taiwanese Armed Forces are seeking to acquire new M109A7 Paladin self-propelled howitzers from the United States. Although this news was initially reported by local media in 2023, this possibility has recently been highlighted as part of the restructuring and modernization program for the Taiwanese Army’s artillery systems.
Under the name “Ruiting Project”, Taiwan had been pursuing the purchase of new self-propelled howitzers from the M109 family. Initially, in 2021, the M109A6 version was one of the options considered by the military. However, due to various reasons, the operation was canceled in favor of opting for more updated units that better align with the island’s capabilities and requirements. In this context, newer versions of the M109 and the High Mobility Artillery Rocket System (HIMARS) were considered.
As a result of these evaluations, 29 HIMARS MLRS systems were acquired under the “Honglei Project.” The first batch of 11 systems has already arrived in Taiwan, with delivery of the remaining 18 units expected by the end of 2026. In this context, in 2023, a spokesperson for BAE Systems mentioned that the 155mm M109A7 self-propelled howitzer had been offered to the Taiwanese Army (RoCA) as an alternative to the previously proposed M109A6 units, which were initially intended for acquisition.
Currently, Taiwan’s Army possesses a fleet of M109A2 and M109A5 self-propelled howitzers acquired from the United States, which have been in service for 30 years. The selection of the most modern version of this U.S.-origin combat artillery vehicle, along with the incorporated HIMARS systems, aims to strengthen the Defensive Strategy adopted by the Taiwanese Armed Forces, which prioritizes asymmetric combat capabilities. These include long-range precision strike capabilities using guided rockets, various types of missiles, and artillery shells deployed by coastal batteries and self-propelled platforms.
Taiwan’s choice of the M109A7 would be a foreseeable step in line with these plans, considering its 30 years of experience with the platform. Although the focus is currently on integrating the second batch of HIMARS systems, the Taiwanese Army has already initiated various ministerial-level negotiations with the United States. More specifically, a request for cost estimates has been submitted for the acquisition of 40 new units currently manufactured by BAE Systems. Once the U.S. response is received, cost analyses for the integration, maintenance, and future operation of the Paladin systems will be conducted to complete the project.
Additionally, if the purchase of the 40 new combat artillery vehicles moves forward, other items should be included, such as M992A3 ammunition vehicles and even the provision of extended-range guided Excalibur shells by the United States.
