I've tried to be as complete as possible and reference the only easily accessible source for this information online for that item (I don't expect everyone owns PDFs of dozens of Battletech books and manuals).
Current Weapons/Equipment We Don't Have (3052)
Arty, all of which have a variety of issues that keeps them out of our mechs in MWO. Hence consumable arty instead.
- Arrow IV, Missile system used as artillery and because it's range and damage model it proved hard for for PGI to code. On top of that it is hard to fit in a mech.
- Sniper Rifle Artillery Piece, more mech equip-able arty, with a 9km(!) range.
- Thumper Artillery Piece, mech/vehicle arty.
- Long Tom Artillery Piece, yet more arty...though at 30 crits and 30 tons it doesn't really fit on a mech.
Mech Mortar, fires volleys of 'missiles' much like lrms but with less guidance. On the other hand they are immune/resistant to AMS. I can see the forum threads over that part now...
Laser Anti-Missile System (LAMS) is available to clan Wolf in 3048 (Fed Com in 3059) and does pretty much what you would expect converting heat (instead of ammo) into anti-missile fire.
Binary Laser Cannon, effectively two large lasers fused into a single weapon giving you 16 damage for 12 heat (only a ER PPC is hotter). It's always pretty much experimental only in lore.
One Shot Launchers & Improved OS Launchers, single shot launchers with reduced weight as they require no ammo reloading. Both exist during this period, but would probably require special coding to ever be used and usually are not worth it.
3056
Light Gauss Rifle, Miniature Gauss Rifle for lighter battlemechs.
3057
Extended Range Small Pulse Laser, Clan Wolf prototype weapon.
Extended Range Medium Pulse Laser, Clan Wolf prototype weapon.
Extended Range Large Pulse Laser, Clan Wolf prototype weapon.
Small X-Pulse Laser, IS attempt to match clan pulse weapon ranges.
Medium X-Pulse Laser, IS attempt to match clan pulse weapon ranges.
Large X-Pulse Laser, IS attempt to match clan pulse weapon ranges.
Streak LRMs, streak version of normal LRM systems though they are twice the size and weight of normal versions. Clan only.
UAC (IS), the IS finally gets a full set of ultra AC weapons.
3058
ER Small Laser (IS), the IS variation of clan ER lasers.
ER Medium Laser (IS), the IS variation of clan ER lasers.
Enhanced Long Range Missiles, Fed Com enhancement to the standard LRMs with lowered minimum range.
Medium Range Missile Launchers, non-guided missile launchers fired more like ACs. They come in 10s, 20s, 30s, and 40s.
Streak SRM4s and 6s (IS), the IS finally gets a full set of Streak Launchers.
LB-X (IS), the IS finally gets a full set of LB-X weapons.
3059
Chemical Lasers, useless to us as they are only for vehicles that use ICE or Fuel Cell engines it's also clan only.
Heavy Small Lasers, even hotter than normal these have increased damage and the range of IS weapons though they are clan only.
Heavy Medium laser, even hotter than normal these have increased damage and the range of IS weapons though they are clan only. This version out damages the Large Laser and generates more heat than a LL.
Heavy Large Laser, even hotter than normal these have increased damage and the range of IS weapons though they are clan only. This version rivals the ER PPC for damage and heat generation.
Hypervelocity Autocannon, extreme range AC weapon that comes in 2, 5, and 10 ratings.
3060
Micro Pulse Laser, an even smaller pulse laser than the spl created and used by the clans.
Extended-Range Micro Laser, ER version of the Micro Laser.
Advanced Tactical Missile (ATM), clan system that has SRM-like damage with near LRM range. Comes in 3, 6, 9, & 12 packs.
3061
Heavy Gauss Rifle, Lyran attempt to increase the power of the normal Gauss Rifle however damage varies by range (from 25 to 10) and it has a minimum range like a PPC. Experimental.
3062
Rotary Autocannon, high rate of fire alternative to the UAC which fires faster (3 times faster than a UAC), but has a higher chance to jam at full speed.
Improved Narc Beacon, range increased NARC system.
3064
Rocket Launchers, one shot fairly long range weapons that fire in a straight line.
Bombast Laser, mostly limited to Solaris and experimental status with variable damage/rate of fire.
3065
Improved Heavy Gauss Rifle, upgrade of the earlier Heavy Gauss with no damage falloff like the earlier model. Not a field weapon until 3081.
3067
Heavy PPC, Combine attempt to match the damage of clan PPCs however it lacks their range (It also has a minimum range like a normal PPC).
Light PPC, Similar damage to a medium laser, but is heavier and larger, it does however have a better range.
Heavy Flamer, More powerful flamer with it's own ammo though the fuel for it can explode when damaged. The IS version comes a year later.
3068
Light Rifle, an old weapon that just had gone 'unused' until 3068 the Light Rifle is lighter than a AC2, does slightly more damage, and has less range.
Medium Rifle, similar to the LR the MR fills a spot much like the AC5 (6 damage, mid range) for a bit less tonnage than an AC5 (5t).
Heavy Rifle, similar to the other two it though it fills a role like the AC10 (9 damage, 8t, mid range).
Light Machinegun, a normal MG except it has increased range, it would effectively replace the MG. The clans have them in 3060.
Heavy Machinegun, it weights twice a normal MG and does 3 damage and would make ballistics lights so happy. The clans have them in 3060.
Machine Gun Arrays, which link MGs (std, Light, or Heavy) into a single weapon system (and hence dual or quad MGs per hardpoint)
Hyper-Assault Gauss Rifle, a rapid high rate of fire gauss weapon that comes in 3 versions depending on the number of shots fired (20, 30, & 40).
Light Autocannon, while developed by the NAIS during the clan invasions it didn't see use until much later it offers the same damage as a normal AC2 or 5 with reduced range, weight, and size.
Multi-Missile Launcher, single system that can fire SRMs or LRMs of any variety as needed. Comes in 3s, 5s, 7s, and 9s.
Plasma Rifle, Mid range weapon comparable to a PPC combined with a flamer, though it requires ammo.
3069
Improved Heavy Small laser, refinement of the Heavy laser line though it explodes when destroyed like gauss rifles do.
Improved Heavy Medium Laser, refinement of the Heavy laser line though it explodes when destroyed like gauss rifles do.
Improved Heavy Large Laser, refinement of the Heavy laser line though it explodes when destroyed like gauss rifles do.
Anti-Personnel Gauss Rifle, Clan light AP gauss that can replace MGs with greater range.
Plasma Cannon, a clan specific more heat focused version of the Plasma Rifle. Against mechs it acts like a flamer doing no damage, but transferring heat.
3070
Improved Advanced Tactical Missile (IATM), adds a streak style guidance system to the original ATM.
Thunderbolt Missile, based on the large single fire missiles first designed in 3053. These missiles do as much damage as an AC round of their rating (5, 10, 15, 20) though otherwise act like LRMs.
3072
Magshot, extremely light MG sized Gauss weapon. Mid-range dealing 2 damage per shot.
3080
Silver Bullet Gauss Rifle, a rapid fire gauss weapon originally designed by NAIS in 3051 and abandoned until the Free Worlds League stole it in 3078.
3082
Extended LRMs, massively extended range (nearly twice that of normal LRMs), however the minimum range is increased as well.
