Air-launched Ballistic Missiles
In 2018, Russia and China both tested an uncommon type of missile that flew a ballistic trajectory but could be launched from an aircraft. Air-launched ballistic missiles (ALBM) are just one curiosity at a time when many countries are rapidly expanding and upgrading their missile inventories, but the tests raised some understandable questions: Is this a new capability? If a country has ground- and sea-launched ballistic missiles, or air-launched cruise missiles, why does it need an ALBM? What is it for?
Examining the phenomenon of air-launched ballistic missiles provides insight into not only the planning of the countries developing these systems, but also the diversity and complexity of missile systems.
The SIPRI chapter describes the nuclear weapon modernization programs underway in each nuclear-armed state and provides estimates for how many nuclear warheads each country possesses.
FAS researchers Hans Kristensen and Matt Korda with the Nuclear Information Project write in the new SIPRI Yearbook 2024, released today.
The total number of U.S. nuclear warheads are now estimated to include 1,770 deployed warheads, 1,938 reserved for operational forces. An additional 1,336 retired warheads are awaiting dismantlement, for a total inventory of 5,044 warheads.
A military depot in central Belarus has recently been upgraded with additional security perimeters and an access point that indicate it could be intended for housing Russian nuclear warheads for Belarus’ Russia-supplied Iskander missile launchers.
