Polar drilling is the most direct method to obtain samples of the polar ice layer or subglacial environment and install scientific observation instruments in ice layer or subglacial environment， and it is a necessary technical method to carry out polar scientific research. The United States is one of the earliest countries that started polar drilling and is also a powerful country in polar drilling technology. Compared with the United States， China’s polar drilling technology is still in its infancy. Based on the Ice Drilling Program long term science plan of America for 2021-2031， and with reference to its official website and related literatures， this article sorts out the scientific goals of polar drilling and the current state of polar drilling technology of the United States， and briefly introduces the polar fieldwork in the past ten years and upcoming fieldwork in the next three years， which are expected to provide some reference for the development of China’s polar drilling.
