In late fall of 2006, the Canadian M777 howitzers were equipped with the Digital Gun Management System (DGMS), which greatly improved accuracy and led to these guns being used for short range close support of Canadian and US ground forces.
They proved so successful that an order for an additional six guns was placed with BAE. In May 2009, the Canadian government ordered a further 25 M777s, bringing the total to 37.

In June 2016, it was announced that 145 guns will be purchased by India for US$750 million. In November 2016 the Indian government completed the deal to buy 145 howitzers from the US. Under the agreement, BAE Systems supplied 25 ready-built howitzers, while 120 guns were manufactured in India by Mahindra Defence Systems Limited.
The Indian Army received its first shipment of two howitzers in 2017 from the United States in ready to use condition. In September 2017, the barrel of one of the howitzers was damaged while firing during calibration trials. The Indian army used the M777 howitzer in the Himvijay exercise in Arunachal Pradesh which involved the newly raised integrated battle groups.
A total of seven artillery regiments are planned, each of 18 guns. The first regiment is planned to be raised by the end of 2020 with 15 guns supplied by BAE systems and three guns supplied by Mahindra Defense Systems Limited.

(25 Apr 2022) How Much Can US Howitzers Help Ukraine?
Explainer Ukraine received 6 additional units from Australia and 4 from Canada, as well as 200,000 155mm rounds and 72 trucks to transport the guns, enough to supply six battalions. Ukrainian forces claim they need this weapon as their own artillery does not have the range of Russian systems, while the M777 has a range greater than Russian weapons.
* Ukrainian Brg. Gen. Volodomyr Karpenko said that M777 is prone to damage by shrapnel from incoming artillery fire. He said that ordinarily two out of six pieces in a typical M777-equipped Ukrainian artillery battery would require maintenance due to shrapnel damage after a typical incoming fire event. Russian forces claim to have seized a damaged and inoperable M777 during fighting in Siversk in eastern Ukraine.
