Design challenge twenty-six features one of the classic BattleTech missile boats, the Trebuchet! Featuring dual LRM-15s this capable long-range fire support asset was originally designed for the SLDF in the final years of the Amaris Coup. The destruction wrought by the 1st Succession War obliterated that early precursor which caused its redesign in 2799 by House Marik where it has become a staple. While not a favorite of mine (especially the lostech 7M ‘upgrade’ which improperly utilizes NARCs in my opinion) this Mech definitely has its uses. I am curious to see if the LRM-5 Marik philosophy can work here but I want to see what you guys can come up with for the Salient Horizon universe.  Unfortunately, I couldn’t find the ’Mech of the Week for the Trebuchet but thankfully we still have sarna to provide us some inspiration.

Design Criteria
Design: Trebuchet Medium BattleMech
Era: 3052, just following the Truce of Tukayyid
Tech: InnerSphere Level 2
Mass: 50 tons

Tech Base
The tech base for this enterprise will be InnerSphere Level 2, also known as Star League lostech, circa 3053. Remember some Level 1 standards which Bradshaw and myself think still have value like Large Lasers and PPCs which feature the same damage factor as their higher tech brethren with less range and perhaps most significantly less heat. Here is a list for your design reference. Let me know if there is anything I missed!

Star League LosTech
Anti-Missile System
Arrow IV Artillery Missile System
Extended Range Large Laser (ER Large Laser)
Extended Range Particle Projection Cannon (ER PPC)
Gauss Rifle
Ultra Autocannon/5
LB 10-X Autocannon
One-Shot Missile Packs
Pulse Lasers (Small, Medium, & Large)
Streak SRM-2
Swarm LRMs
Thunder LRMs
Artemis IV FCS
Beagle Active Probe
Guardian ECM Suite
Myomer Accelerator Signal Circuitry (MASC)
Narc Missile Beacon
TAG
Cellular Ammunition Storage Equipment (CASE)
Double Heat Sinks
Endo Steel Internal Structure
Ferro-Fibrous Armor
Extra Light (XL) Engine

InnerSphere Low Tech
Blazer Cannon (or Binary Laser)
Recon Camera
Remote Sensor Dispenser

New Innovations
Triple Strength Myomer
Hatchet
C3 Computer

Design Traits of this Setting
Both the Federated Commonwealth and ComStar seem to have gone in the other direction with LRM batteries preferring larger LRM-15s and 20s linked to Artemis IV FCS to enhance accuracy. Facing the technologically superior Clan invaders have caused them to spend vast sums of resources on the finest technology available usually translating into high priced BattleMechs that few other factions can afford.
This is somewhat true for the Draconis Combine which has lost a significant portion of their industrial capacity to the Clans. This has been forced Kurita designers to innovate in new and different ways regardless of traditional warrior ethos which pervades the realm. Many Draconis optimizations have included the C3 System which is accelerated from the canon setting which saw their deployment lag.
The Free Worlds League in particular have embraced massed LRM-5s over the larger batteries to provide closer mass equivalents to Clan LRMs. Thanks to a corresponding increase in NARC units these ‘fire teams’ have become quite effective in the Marik Civil War. Also, the Blazer has made an appearance in the shattered FWLM searching for an advantage over their former brethren.
The Capellan Confederation typically fields cost effective designs at this time thanks to their resource strapped situation. While justifications for high end increases can be made like the Outreach Conference, Wrath of Blake technical aid, spoils of war from Isis forces, and good old Capellan espionage these should be minimized. My advice would be Periphery plus for these designs as the Confederation is under strain supporting Isis right now as it is. Growing stealth tech reflected in the Raven would be appropriate in many cases as sophisticated electronic lostech devices like the Guardian ECM Suite would be a priority for their recon designs. There is also a fire support role which is a hallmark of Liao tactical doctrine. The discovery of Thunder LRMs to deploy minefields and use of Arrow IV Artillery on the Catapult are themes which could be amplified here.
Regional factions like the Draconis March and the Periphery have seen the introduction of some ‘simple’ lostech items like Double Heat Sinks, Ferro-Fibrous, Streak SRM-2s, and Pulse Lasers. Extra-Light (XL) Engines remain too expensive and have drawbacks which make their deployment unlikely here. Advanced orbital facilities needed for EndoSteel manufacturing also remain out of reach at this point. They are not beyond using PPCs and Large Lasers either which they view as more efficient than their ER successors.

Please do your research (think Objective Raids) for available components as this will be another factor in rapid production. I love fluff and your winning designs will be featured in my BattleTech Salient Horizon alternate setting. I'd like to go beyond the refits bought to you by Technical Readout 3050 and delve into extensive redesigns of your BattleTech favorites. Sharpen up your favorite war machines perhaps drawing on past or current variants while remembering the spirit or role of these Mechs. Don't forget to justify the expense of your project and multiple winners are possible. Figure that all entries have to be completed and posted on these forums by Friday September 11th, 2020 by 11:59 PM which should give you all a full two weeks for this contest, good luck!!
