General Details
Name:  LRT 20 (Prototype)
Type (Category):  Weapon (Missile)
Technology:  Primitive, Inner Sphere
Available To:  BattleMechs (BM), IndustrialMechs (IM)
Reference:  Interstellar Operations (p. 117)

Description:
Considered by many a niche class of LRM and SRM systems—and sometimes erroneously classified as a special munition for standard launchers—torpedoes are the maritime-only versions of their surface-launched kin. Though they are as effective underwater as missiles are in most respects, torpedoes are almost never seen on BattleMechs or vehicles not specifically designed for blue-water operations. The standard short-range torpedo (SRT) and long-range torpedo (LRT) launchers’ munitions cannot be swapped out for standard missiles because of physical differences in the launch mechanisms. This incompatibility has, understandably, led to little love for this weapon system, and so few manufacturers mass produce them today. In fact, the Sea Devastator LRT-20 and Sea Harvester SRT-6 systems—both employed on the Galtorproduced Neptune combat submarine—are the best known of these weapons Inner Sphere-wide, and represent less than one percent of munitions sales by these companies.

Game Rules:
Missile launchers may not be fired if the unit is shut down or if its pilot/crew is otherwise prevented from acting, but loaded or partially loaded missile ammo bins are always live and will explode per standard rules if critically hit during game play.

Primitive prototype missile weapons (standard LRMs, SRMs, and their torpedo equivalents) apply a –2 modifier on the Cluster Hits Table for every successful attack, treating any modified result of 1 or less as a minimum result of 2.

Construction Rules:
May be mounted on any available unit type in accordance with the unit’s standard construction rules.

Special Unit Abilities
The special unit abilities described here are intended for use with the Alpha Strike rule system:
 Torpedo (TOR)
Torpedo launchers may only be launched by units in water (or on the surface of a water feature), against targets that are also on or in water (this includes units like hovercraft and airborne WiGEs operating just above the surface of water). Torpedo special ability damage is given in range brackets like a standard weapon attack, and may be fired separately or combined with the standard weapon damage that a submerged unit may deliver in combat.

Torpedo attacks ignore underwater range and damage modifiers that affect other weapons. For example, if a submerged unit, with damage values of 2/2/2 and a TOR 3/3 special, fires at a target that is in its underwater Short range bracket, it will deliver 4 points of total damage on a successful attack. (The base damage of 2 for its normal weapons is halved to 1, but the full TOR damage of 3 applies without reduction.)
