The United States announced a series of measures in response to Russia's suspension of New START.

First, it suspended biannual exchange of detailed data on treaty-accountable items and facilities. Normally, these exchanges reflect the status of strategic forces as of 1 March and 1 September. The format of these exchanges is described in Part Two of the New START Protocol. It's a fairly detailed list that includes, for example, the information about the number of ICBMs deployed at each base, non-deployed ICBMs and launchers with their unique IDs, etc. All that is now withheld by the United States from Russia.

These exchanges have not been truly public. The United States would normally made available the unclassified version of its submission to those who requested it. Hans Kristensen would normally made them public - here is, for example, the 1 September 2012 exchange. However, unlike in old START, the United States cannot make public Russia's New START data - the treaty explicitly does not allow that.

The only exception are the aggregate numbers that each party was free to disclose. These are the number of deployed delivery vehicles, the number of deployed warheads, and the total number of launchers. Despite withholding the detailed exchange, the United States published its own aggregate numbers in May 2023, listing "No provided" in Russia's column.

It is not entirely clear if the United States will continue this practice and publish its aggregate numbers as of 1 September 2023.

Other measures implemented by the United State is the withholding of notifications (with the exception of ballistic missile launch notifications under the 1988 agreement that Russia will also continue), suspension of inspections and telemetry exchange.
