Trident Ballistic Missile Submarine
It's a submarine-launched ballistic missile system comprised of the Trident missile, the special Trident warheads and the Ohio-class ballistic missile sub.
USS George Washinton.
The Ohio Class ballistic missile submarine at 560 feet in length.
The Romans created the first ballista. It looked like a very large cross bow. It throws things a long way (relatively). A ballistic missile throws itself. An anti-ballistic missile throws itself at the incoming ballistic missile.
The Soviet Union built 4 new classes of submarine-launched ballistic missiles and over 60 new missile submarines.
The M45 submarine-launched ballistic missile was first tested in 1986. It was fired in 2004 from the Vigilant at a target near French Guinea, which it hit.
An ALBM is an air-launched ballistic missile, a ballistic missile launched from a bomber.
Modern submarines carry a wide variety of weapons. An example of a U.S. Navy Fast-Attack Submarine weapons capability includes: Homing Torpedoes (Active and Passive Sonar) Tomahawk Land-Attack Missile (Conventional and Nuclear) Tomahawk Anti-Ship Missile Harpoon Anti-Ship Missile Mines Ballistic Missile submarines can carry those weapons as well, but their primary mission is Nuclear Deterrence, and as such their main weapons are Submarine Launched Ballistic Missiles (SLBM's).
The codes are- for conventional () non nuclear powered) Submarines- SS ( for example the U.S.S. is SS-297. Atomic subs are SSN or SSBn - BN if fitted for Ballistic missiles such as the Polaris or Trident types ( there is no Submarine Called the Polaris- it is a guided missile!) so SS- submarine, SSN- Nuclear submarine- SSBN- Nuclear submarine- Missile type.
The term comes from the "B" and "M" letters in the acronym, "FBM", which stands for Fleet Ballistic Missile (Fleet Ballistic Missile Submarine). The combined "BM" was translated into a Navy nickname, Boomer. It's similar to a BMW automobile being called a Beemer. The fact that ballistic missiles go "boom" when they explode also played a role in the slang term. Otherwise, they could have been called "beemers" also.
