Weapons technology in the Honorverse

In David Weber's Honor Harrington military science fiction novels, warfare is naturally ubiquitous. Two thousand years in the future, it remains true that humans will devise ever more ingenious ways of causing death and destruction.

Lasers
The most common energy weapon.

Grasers
Lasers operating in the gamma ray range; not much is known about them.

Energy torpedoes
Not actually torpedoes of any kind, they are self-sustaining masses of plasma that can be projected against targets at short range. They are very destructive, but are completely stopped by sidewalls.

Grav lance
The grav lance is huge, short-ranged and requires almost all the firing ships' power. However, it is the only weapon designed to cause damage to sidewalls, and is quite effective against them. Admiral Sonja Hemphill promoted this weapon.

The Crippler
A more advanced form of the grav lance, the Crippler was intended to not just destroy the target's sidewalls but overload its engines. However, it actually only worked against merchant ships.

Pulsers
Pulsers are mass drivers using gravity rather than electromagnetism to drive projectiles. A typical pulser pistol has a caliber of 2 mm and a muzzle velocity of 2000 m/s. "Darts", as the projectiles are known, are often fitted with explosive warheads. It is essentially unheard of for anyone to survive a pulser hit.

Flechette guns
Similar to pulsers, these weapons are the equivalent of shotguns.

Portable missiles
Similar to bazookas, these shoulder-braced launchers fire impeller drive missiles with an acceleration of 3000 Gs. As with ship-fired countermissiles, the wedge is the warhead.

Disruptors
These are ultrasonic weapons, considerably less destructive than pulsers. Honor Harrington lost her left eye to a disruptor shot.
