US inventory of Tomahawk missiles

US President Donald Trump said yesterday, Thursday, that his country cannot “exhaust” its stock of Tomahawk missiles that Ukraine is seeking to obtain from the United States to respond to Russian attacks, in response to the possibility of supplying Ukraine with this type of missile.

Trump responded to a question about these winged (cruise) missiles that his Ukrainian counterpart, Volodymyr Zelensky, wants to convince him to obtain, and said, “We cannot exhaust our country’s (reserves).”

“We also need it, so I don’t know what we can do,” he added.

While it is not known exactly how many Tomahawk missiles the United States possesses, there are estimates about the American stock of winged missiles.

The former Pentagon employee, Mark Cancian, estimated the approximate total number of Tomahawk missiles in the American inventory in 2023 at about 4,150 Tomahawk missiles.

As for the Wikipedia website, it indicates that the US Navy has a reserve of more than 3,500 Tomahawk missiles.

The encyclopedia indicated that American forces used more than 1,900 in previous military confrontations.

But Cancian, like Trump, does not believe that this number is sufficient to transfer a significant portion of the Tomahawk missiles to Ukraine.

Cancian noted that the United States could abandon a number of these missiles to Ukraine, but they would not be enough to transform the war or against Russian forces fighting in eastern Ukraine.

The United States recently used several dozen Tomahawk missiles to bomb sites in Yemen and Iran, with reports indicating that American forces have already used up to 120 missiles after 2022.

According to Cancian, the 2026 budget allocates only 57 missiles for the US military, and the United States may need Tomahawk missiles to launch attacks on Venezuela, for example.

The latest budget documents show that the US Navy has not purchased any new missiles in the following years, and that the US Marine Corps bought only 22 missiles last year, according to the Associated Press.

The US military’s inventory of Tomahawk missiles (mainly held by the Navy, with emerging land-launched capabilities by the Army and previously by the Marines) is estimated at approximately 4,000–4,150 active missiles through 2025, according to AI estimates from the GROK platform.

This figure takes into account historical purchases of approximately 9,000 Tomahawk missiles through 2023, less combat expenditures (e.g., more than 2,300 missiles launched in previous conflicts and at least 135–200+ missiles used to strike the Houthis in Yemen during 2024–2025), with limited compensation from new production rates of about 5 missiles per month. Starting in early 2025.

Exact numbers are classified as classified information, and recent reports point to concerns about depleting stocks amid slow replenishment and the lack of large purchase orders in recent budgets.
