How are missiles launched from a submarine?
Robert Guerrero
Updated on March 31, 2026
Missile is ejected from underwater launch tube by compressed air. Missile reaches water surface and the tip of the missile breaks the water surface. The rocket boosters fire and propel the missile into its path. Boosters fall off and the engines continue to propel it.
Also know, can submarines launch nuclear missiles?
A submarine-launched ballistic missile (SLBM) is a ballistic missile capable of being launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs) each of which carries a nuclear warhead and allows a single launched missile to strike several targets.
Likewise, how many nuclear missiles does a submarine carry? Each SSGN is capable of carrying 154 Tomahawk cruise missiles, plus a complement of Harpoon missiles to be fired through their torpedo tubes. As part of the New START treaty, four tubes on each SSBN will be deactivated, leaving each ship with only 20 available for war loads.
Similarly, you may ask, do submarines have to surface to fire missiles?
The eventual goal was a system that kept the submarine underwater at all times. No need to surface even to confirm the submarine's location prior to missile launch. The American Polaris system set the pattern for a missile system that could launch while submerged giving little if any warning to a potential enemy.
How is a missile launched?
Ballistic missiles are primarily surface-launched from mobile launchers, silos, ships or submarines, with air launch being theoretically possible with a weapon such as the cancelled Skybolt missile.

Modern submarine-launched ballistic missiles are closely related to intercontinental ballistic missiles, with ranges of over 5,500 kilometres (3,000 nmi), and in many cases SLBMs and ICBMs may be part of the same family of weapons.How long can nuclear submarines stay underwater?
The limits on how long they can stay underwater are food and supplies. Submarines generally stock a 90-day supply of food, so they can spend three months underwater. The diesel-powered submarines (not now used by the United States Navy) had a limit of several days submerged.How far can a torpedo go?
