The RCH 155 is not only powerful but also highly automated, designed to function with minimal human intervention. Its automation allows for operations like firing on the move— a first for most howitzers—significantly increasing its operational effectiveness by minimising the time stationary, thus reducing vulnerability to enemy fire. Operational Capabilities • Engine Power: Equipped with an MTU 8V199 TE21 diesel engine, delivering up to 816 horsepower. • Mobility: Can reach speeds up to 103 km/h on roads, with an operational range of 700 km. • Ammunition Capacity: Carries 30 fused rounds and 144 modular propellants, with a maximum rate of fire of 9 rounds per minute. • Protection: Crew protection against heavy machine gun fire, artillery fragments, mines, and equipped with NBC (Nuclear, Biological, Chemical) protection. Interestingly, the builders say it is designed for future adaptations to be operated remotely, reducing the need for crew exposure in hazardous conditions.

The war had a profound impact on Australian society, politics, and its international relationships, particularly with the United States. Prior to World War II, Australia’s foreign policy was closely aligned with Britain. However, during and after the war, Australia began to seek stronger defence ties with the United States. This shift was driven by growing concerns over security in the Asia-Pacific region and the perceived threat of communist expansion. By the 1950s, Australia had established closer ties with the US through agreements such as the ANZUS Treaty (1951), which formalized a security pact between Australia, New Zealand, and the United States. Additionally, Australia joined the Southeast Asia Treaty Organization (SEATO) and provided financial aid and support to South Vietnam as part of its commitment to containing communism. Australia’s involvement in Vietnam began in 1962, when the Menzies government sent a contingent of military trainers to assist the South Vietnamese army. By 1964, the government introduced conscription to increase the size of its defence force, a decision that proved controversial within Australian society. The first Australian combat troops were deployed to Vietnam in 1965, marking the start of Australia’s direct military engagement in the conflict. In 1966, Australian forces were given responsibility for Phuoc Tuy province, located about 50 miles east of Saigon. They established a major base and airstrip at Nui Dat and worked
