Following the aftermath of the [[Great War|first Shivan Incursion]] and the [[GTI Rebellion|Hades Rebellion]], the Terrans and Vasudans were mesmerized at the technological capability of the [[SD Lucifer|Shivan command ship]]'s main guns, which they termed as "Flux Cannons", the two species attempted to adopt such a technology. The result was the invention of the deadliest, and most advanced weapons of war created, called "Beam weapons". '''Beam weapons''' were invented in 2355, after the Hades Rebellion. The first class of ship which was fully designed with beam weapons in mind may have been the [[GVCv Sobek|GVCv ''Sobek'']], which is said to have entered service "after the destruction of Vasuda Prime." These weapons opened a door for advanced technology to flow into the GTVA's arsenal.

A Ravana-class destroyer firing two of its frontal primary beam weapons upon exiting subspace

Beam weapons, or beam cannons, are powerful weapons systems mounted exclusively on warships. They are used to engage other warships in combat, and for point defense against fighters, bombers, and warheads.

History

During the Great War and the GTI Rebellion, the Terrans and Vasudans encountered the Shivans, a previously unknown alien race. Both species took note of the technological capability of the Shivans, particularly the main guns of the Shivan command ship, which they termed "Flux Cannons". The two races opted to replicate this technology after the end of the GTI Rebellion in late 2335. The result of this pursuit was the invention of the deadliest and most advanced weapons of war ever created by either race, called beam weapons. The first class of ship which was fully designed with beam weapons in mind may have been the GVCv Sobek, which is said to have entered service shortly after the destruction of Vasuda Prime. Further advancements enabled engineers from both races to mount these weapons on older vessels never meant to accommodate them, as well as less powerful, more energy-efficient versions on smaller ships.

Despite these advances, neither species was ultimately capable of matching up to the Shivans during the Second Shivan Incursion of 2367. Shivan beams were far more destructive than any Terran or Vasudan beam weapon ever made in terms of raw power and were capable of much faster refire rates at no visible cost to ship integrity. These advantages that Shivan beam weapons have over their Terran and Vasudan counterparts were demonstrated when the most powerful ship ever constructed by both races, the GTVA Colossus, was obliterated almost completely by beam fire from a Sathanas juggernaut.

Capabilities

Sufficient reactor power is required in order to fire beam weapons. Therefore, they are never mounted on fighters or bombers, which have reactors too small and too weak to support the power drain. For a time, the Vasudans' Typhon-class destroyers encountered similar issues, with most of them suffering from reactor overloads and system failures due to their power grid being unable to cope with the power needed to fire the beams equipped on them. The deployment of the Hatshepsut line of destroyers would rectify this problem.

In general, beam weapons are designed to be fired against ships larger than bomber-class, which are large enough to be targeted with. These are generally called "anti-capship beams" by players. However, smaller, lighter beam weapons exist that deliver less damage than anti-capship beams but are capable of targeting even fighters and bombers. These are recognized as "anti-fighter beams" in FreeSpace canon (dubbed "AAA beams" on occasion by players due to their names in the FreeSpace 2 table files). The advancement of the beam weapon in the Terran and Vasudan fleets is sufficient enough to enable the most powerful anti-capship beam from either race to easily cleave through most cruisers and corvettes in minutes and deal significant damage to destroyers, if not destroying them outright.

Most Terran and Vasudan beam weapons are meant to be fired at a specified power output, dealing a consistent rate of damage assuming that the beam in question strikes its target for the entire duration of its lifetime. However, if the situation warrants, it is also possible to reduce power output to limit damage done, or increase power output beyond specified limits to increase damage rates; the latter comes with the risk of emitter and heat sink deterioration. Examples of ships that have taken either course of action are the GTC Rampart during a feint attack on two cruisers, and the GTVA Colossus, during its engagement with SJ Sathanas 01.

Beam types

There are four beam types included in retail FreeSpace 2, but only the first three were used throughout the course of the game.

  1. Direct-fire beams, which are essentially standard-issue point-and-shoot weapons. These beams can be directed to target specific sections of the target ship if necessary.
  2. Slashing beams, which strike their targets across a wide arc. Slashing beams have a marginally higher damage output and faster refire rate than direct-fire beams, but are much more inaccurate and may completely miss the target on occasion.
  3. Anti-fighter beams, which can target vessels smaller than cruiser-class. These beams are capable of firing more than once per pulse, but do very little damage as compared to direct-fire or slashing beams. Under the most dire circumstances, they may be used against larger vessels as well.
  4. Targeting beams, which are never used in the game and whose purpose remains unknown. One beam of this type (the Targeting Laser) is included in the FreeSpace 2 tables, but it appears to serve no purpose due to supplementary content being cut.

Both the Terrans and Vasudans manufacture and make use of the first three beam types. The Shivans, however, utilize only the first and third types.

Notes for mission designers

See also: SEXP Reference

Newly-created missions in FRED2 do not enable beams by default. The easiest way to enable beam fire is to use the beam-free-all SEXP on every individual ship that needs to fire its beams. Greater control over each beam can be achieved through the use of the fire-beam SEXP, allowing beams to target specific ships, subsystems and turrets.

fred2_open adds an option to enable all beams by default in the Mission Statistics box.
