The Brazilian government asked to buy 40 M109A5 kits, to upgrade its self-propelled howitzers, and 434 M113a2MK1 kits, which will be used to modernize the country's armored personal carriers.
The packages include spare parts, support equipment, tools and test equipment, personnel training, publications and technical documentation, and engineering and logistics support. BAE Systems is the principal contractor for the deal.
According to the Defense Security Cooperation Agency, the Pentagon agency that oversees all major arms sales, Brazil will use the equipment to "modernize its artillery capability" and enhance their military's readiness.
"The proposed sale will contribute to the foreign policy and national security of the United States by helping to improve the security of Brazil, which has been, and continues to be, an important force for regional stability and economic progress in South America," the DSCA said in a statement.
In May, the country bought 20 Boeing Harpoon Block II Missiles for $169 million from the U.S.
Congress, who was notified of the possible transaction Wednesday, has 30 days to block or modify the sale.
